Abstract: A method for processing a silver halide color photographic material including a step of developing the material with a developer containing an aromatic primary amine color developing agent and at least one compounds represented by the following general formulae (Ia) and (Ib): wherein R¹, R², R³ and R⁴, which may be the same or different, each represents a hydrogen atom or an unsubstituted alkyl group; R⁵, R⁶ and R⁷, which may be the same or different, each represents an unsubstituted alkylene group; X¹ and X², which may be the same or different, each represents -O-, -S-, -CO-, -SO₂ or -SO-, or a combination thereof, and R⁸ represents a hydrogen atom or an unsubstituted alkyl group; and m and n, which may be the same or different, each is 0, l, 2 or 3; and wherein R¹³ represents a substituted alkylene group; and R⁹, R¹⁰, R¹¹ and R¹², which may be the same or different, each represents a hydrogen atom, a substituted or unsubstituted alkyl group or a substituted or unsubsti­ tuted aryl group. The developer has superior stability and reduces fogging in continuous processing.

Description: The present invention relates to a method for processing silver halide color photographic materials using a color developing solution with improved stability and color formation properties that remarkably limits the increase in fogging in continuous processing. Color photographic developing solutions containing aromatic primary amine color developing agents have long been conventionally used in the formation of color images, and now have a major role in the color photographic image formation process. However, it is well known that conventional color developing solutions are easily oxidized by air or metals, and that if the developing solutions thus oxidized are used to form a color image, fogging increases, sensitivity or gradation changes, and therefore the photographic characteristics are adversely affected. Therefore, various measures to improve the preservability of color developing solutions have been studied, and use of a combination of hydroxylamine and sulfite ions is the most general current practice. However, when hydroxylamine decomposes, ammonia is released, which causes fogging, and a sulfite ion acts as a competing compound against developing agents, for example, to disadvantageously reduce their color formation capability, so that neither is a preferred preservative. Particularly, although sulfite ions have been used to improve the preservability of various developing agents or to prevent decomposition of hydroxylamine, it greatly impedes color development, and when they are used in a system without benzyl alcohol (which is disadvantageous from the point of view of environmental pollution and preparation of a developing solution), the developed color density is significantly lowered. Alkanolamines described in Japanese Patent Application (OPI) No. 3532/79 (corresponding to U.S. Patent 4,170,478) (the term "OPI" as used herein refers to a "published unexamined Japanese patent application") and polyethyleneimines described in Japanese Patent Application (OPI) No. 94349/81 (corresponding to U.S. Patent 4,252,892) are suggested as compounds that can be substituted for sulfites, but these compounds remain unsatisfactory. Conventionally, to improve the stability of color developing solutions, various preservatives and chelating agents have been studied. For example, preservatives include aromatic polyhydroxy compounds described in Japanese Patent Application (OPI) Nos. 49828/77, 160142/84 and 47038/81 (corresponding to U.S. Patent 4,264,716) and U.S. Patent 3,746,544; hydroxycarbonyl compounds described in U.S. Patent 3,615,503 and British Patent 1,306,176; α-aminocarbonyl compounds described in Japanese Patent Application (OPI) Nos. 143020/77 (corresponding to U.S. Patent 4,155,764) and 89425/78; metal salts described in Japanese Patent Application (OPI) Nos. 44148/82 (corresponding to U.S. Patent 4,330,616) and 53749/82; and hydroxamic acids described in Japanese Patent Application (OPI) No. 27638/77 (corresponding to U.S. Patent 4,055,426). Chelating agents include aminopolycarboxylic acids described in Japanese Patent Publication Nos. 030496/73 and 30232/69 (corresponding to U.S. Patent 3,462,269); organic phosphonic acids described in Japanese Patent Application (OPI) No. 97347/81, Japanese Patent Publication No. 39359/81 (corresponding to U.S. Patent 3,794,591) and West German Patent 2,227,639; phosphonocarboxylic acids described, for example, in Japanese Patent Application (OPI) Nos. 102726/77 (corresponding to U.S. Patent 4,083,723), 42730778, 121127/79, 126241/80 and 65956/80 and compounds described, for example, in Japanese Patent Application (OPI) Nos. 195845/83 (corresponding to U.S. Patent 4,482,626) and 203440/83 and Japanese Patent Publication No. 40900/78. However, even if these techniques are used, preservative performance is inadequate, or the photographic characteristics are adversely affected, so that satisfactory results have not yet been attained, and excellent preservatives that can be substituted for sulfites are still keenly sought. In the case of color photographic materials containing a silver chlorobromide emulsion with a high chlorine content, fogging is liable to occur during color development as described in Japanese Patent Application (OPI) Nos. 95345/83 and 232342/84. When such an emulsion is used, it is essential to use a preservative that dissolves the emulsion to a reduced extent and has better preservability, and satisfactory preservatives from this viewpoint have not been found. EP-A-0231870 which is prior art by virtue of Article 54(3)EPC discloses a method for color image formation comprising imagewise exposing a color photographic light-sensitive material comprising a reflective support having provided thereon at least one light-sensitive layer containing a color coupler capable of forming a color image upon coupling with an oxidation product of an aromatic primary amine developing agent and a silver halide emulsion and processing the exposed light-sensitive material with a color developing solution containing substantially no benzyl alcohol within a development time of 2 min and 30 s, wherein said processing is carried out in the presence of specific polyamine compounds. Hydoxylamine may be used as preservative. GB-A-1080106 discloses a process for the production of a developed color photographic material which comprises treating the photographic silver halide material with a silver halide color development solution comprising a primary amine color developinment agent and a specific amine. The developer comprises hydroxylamine hydrochloride. FR-A-870256 discloses the use of a heterocyclic base, e.g. piperidine, to produce color images having an excellent brilliancy. DE-A-2740322 discloses a process for developing a silver halide photographic material with a developer solution comprising an aromatic primary amino, hydroxyl-amine or a hydroxylamine derivative and a 1-aryl-3-pyrazolidone derivative. It is the object of the invention to provide a method for processing a silver halide color photographic material using a color developing solution that is excellent in stability and that remarkably limits increase in fogging in continuous processing as well as excellent in color formation property even by processing the silver halide color photographic materials with a color developing solution substantially free from benzyl alcohol.

The color developing solution used in the present invention is now described in greater detail. The color developing solution used in the present invention contains a known aromatic primary amine color developing agent.

The substituent for the aryl group includes the same groups as those for the above-described alkyl group and the alkenyl group. R²¹ and R²² may be the same or different, and the substituents for R²¹ and R²² may be the same or different. Preferably, the carbon number of each of R²¹ and R²² is from 1 to 10, more preferably from 1 to 5. Nitrogen-containing heterocyclic rings that may be formed by R²¹ and R²² include a piperidyl group, a pyrrolidyl group, an N-alkylpiperidyl group, a morpholyl group, an indolinyl group and a benzotriazole group. Preferred substituents for R²¹ and R²² are a hydroxyl group, an alkoxy group, a sulfonyl group, an amido group, a carboxyl group, a cyano group, a sulfo group, a nitro group and an amino group. Specific examples of compounds represented by general formula (II) used in the present invention are given below. Compounds represented by general formula (II) can be synthesized by known processes as described in U.S. Patents 3,661,996, 3,362,961 and 3,293,034, Japanese Patent Publication No. 2794/67 and U.S. Patents 3,491,151, 3,655,764, 3,467,711, 3,455,916, 3,287,125 and 3,287,124. These compounds may form salts with acids such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, oxalic acid and acetic acid. In addition to hydroxylamines, other "compounds capable of directly stabilizing a developing agent" include, for example, hydrazines and hydrazides as described in Japanese Patent Application Nos. 170756/86, 171682/86, 173468/86, hydroxamic acids as described in Japanese Patent Application No. 186559/86 and α-hydroxyketones as described in Japanese Patent Application No. 188741/86. The amount of these compounds to be added to a color developing solution is preferably about 0.01 g to 30 g, more preferably about 0.1 g to 20 g, and most preferably about 0.5 to 10 g, per l of the color developing solution. Other preservatives may be added, if desired, for example, sulfites such as sodium sulfite, potassium sulfite, sodium bisulfite, potassium bisulfite, sodium metasulfite and potassium metasulfite, or carbonyl sulfite adducts. The amount of these to be added to a color developing solution is 0 g to about 20 g/l, preferably 0 g to about 5 g/l, and it is preferable to use the smallest amount necessary to provide stability to a color developing solution. Examples of such other preservatives are hydroxyacetones described in U.S. Patent 3,615,503 and British Patent 1,306,176; α-aminocarbonyl compounds described in Japanese Patent Application (OPI) Nos. 143020/77 and 89425/78; metals described in Japanese Patent Application (OPI) Nos. 44148/82 and 53749/82; sugars described in Japanese Patent Application (OPI) No. 102727/77; α,α′-dicarbonyl compounds described in Japanese Patent Application (OPI) No. 160141/84; salicylic acids described in Japanese Patent Application (OPI) NO. 180588/84; and gluconic acid derivatives described in Japanese Patent Application (OPI) No. 75647/81; and two or more of these can be used in combination, if desired. Of these compounds, aromatic polyhydroxy compounds are preferred. Preferably, the pH of the color developing solution used in the present invention is about 9 to 12, more preferably about 9 to 11.0, and other known compounds that are components of developing solutions can be added to the color developing solution. To maintain the pH, preferably, various buffers are used. Buffers include carbonates, phosphates, borates, tetraborates, hydroxybenzoates, glycine salts, N,N-dimethylglycine salts, leucine salts, norleucine salts, guanine salts, 3,4-dihydroxyphenylalanine salts, alanine salts, aminobutyrates, 2-amino-2-methyl-1,3-propanediol salts, valine salts, proline salts, trishydroxyaminomethane salts and lysine salts. In particular, carbonates, phosphates, tetraborates and hydroxybenzoates are excellent in solubility and buffering performance in a high pH range of 9.0 or above. When they are added to the color developing solution, advantageously they do not adversely affect photographic performance (e.g, cause fogging), and they are inexpensive, so that it is particularly preferred to use these buffers. Examples of these buffers are sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, trisodium phosphate, tripotassium phosphate, disodium phosphate, dipotassium phosphate, sodium borate, potassium borate, sodium tetraborate (borax), potassium tetraborate, sodium o-hydroxybenzoate (sodium salicylate), potassium o-hydroxybenzoate, sodium 5-sulfo-2-hydroxybenzoate (sodium 5-sulfosalicylate) and potassium 5-sulfo-2-hydroxybenzoate (potassium 5-sulfosalicylate). Preferably, the amount of the buffer added to the color developing solution is at least about 0.1 mol/l, more preferably about 0.1 mol/l to 0.4 mol/l. Various chelating agents can be used in the color developing solution to prevent precipitation of calcium and magnesium or to improve the stability of the color developing solution. Preferred chelating agents include organic compounds such as aminopolycarboxylic acids described in Japanese Patent Publication Nos. 30496/73 and 30232/69, organic phosphonic acids described in Japanese Patent Application (OPI) No. 97347/81, Japanese Patent Publication No. 39359/81 and West German Patent 2,227,639, phosphonocarboxylic acids described, for example, in Japanese Patent Application (OPI) Nos. 102726/77, 42730/78, 121127/79, 126241/80 and 659506/80 and compounds described, for example, in Japanese Patent Application (OPI) Nos. 195845/83 and 203440/83 and Japanese Patent Publication No. 40900/78.

Two or more of these chelating agents may be used in combination, if desired. The amount of these chelating agents added is any amount enough to capture the metal ions in the color developing solution, for example, on the order of about 0.1 to 10 g per l. If desired, a development accelerator may be added to the color developing solution, without particular limitation. However, in view of prevention of environmental hazards, ease of preparation of the solution, and prevention of fogging, the present color developing solution is substantially free from benzyl alcohol. Herein, the term "substantially free from benzyl alcohol" means that the amount of benzyl alcohol per liter of color developing solution is up to about 2 mℓ, and preferably no benzyl alcohol is added. The compounds represented by general formulae (Ia) and (Ib) used in the present invention have a remarkable effect in stabilizing a color developing solution substantially free from benzyl alcohol. Other development accelerators that can be used include thioether compounds disclosed, for example, in Japanese Patent Publication Nos. 16088/62, 5987/62, 7826/63, 12380/69 and 9019/70 and U.S. Patent 3,813,247; p-phenylenediamine compounds disclosed in Japanese Patent Application (OPI) Nos. 49829/77 and 15554/75; quaternary ammonium salts disclosed, for example, in Japanese Patent Application (OPI) No. 137726/75, Japanese Patent Publication No. 30074/69 and Japanese Patent Application (OPI) Nos. 156826/81 and 43429/77; p-aminophenols described in U.S. Patents 2,610,122 and 4,119,462; amine compounds described, for example, in U.S. Patents 2,494,903, 3,128,182, 4,230,796 and 3,253,919, Japanese Patent Publication No. 11431/66 and U.S. Patents 2,482,546, 2,596,926 and 3,582,346; polyalkylene oxides disclosed, for example, in Japanese Patent Publication Nos. 16088/62 and 25201/67, U.S. Patent 3,128,183, Japanese Patent Publication Nos. 11431/66 and 23883/67 and U.S. Patent 3,532,501; as well as 1-phenyl-3-pyrazolidones; hydrazines; mesoionic compounds; ionic compounds; and imidazoles, which can be optionally used. In the present invention, an antifoggant can be optionally used without limitation, including alkali metal halides such as sodium chloride, potassium bromide and potassium iodide and organic antifoggants. Typical examples of organic antifoggants include nitrogencontaining heterocyclic ring compounds such as benzo-triazole, 6-nitrobenzimidazole, 5-nitroisoindazole, 5-methylbenzotriazole, 5-nitrobenzotriazole, 5-chlorobenzotriazole, 2-thiazolylbenzimidazole, 2-thiazolylmethylbenzimidazole, indazoles, hydroxyazaindolizine and adenine.

It is preferred that the replenishing amount be small and the replenishing amount is generally about 20 to 600 mℓ, preferably about 50 to 300 mℓ, and more preferably about 100 to 200 mℓ, per m² of the photosensitive material processed according to the invention. The bleaching solution, the bleach-fix solution and the fixer used in the present invention are now described. Although any conventional bleaching agent can be used in the bleaching solution or the bleach-fix solution used in the present invention, it is preferred to use organic complex salts of iron (III) (e.g., complex salts of aminopolycarboxylic acids (such as ethylenediaminetetraacetic acid and diethylenetriaminepentaacetic acid) and organic phosphonic acids (such as aminopolyphosphonic acids and phosphonocarboxylic acids)), organic acids such as citric acid, tartaric acid and malic acid; persulfates; and hydrogen peroxide. In these compounds, organic complex salts of iron (III) and persulfates are preferred from the viewpoint of quick processing and the prevention of environmental pollution. Examples of aminopolycarboxylic acid and aminopolyphosphonic acid or organic phosphonic acid useful for forming the organic complex salts of iron (III), are: Ethylenediaminetetraacetic acid, Diethylenetriaminepentaacetic acid, Ethylenediamine-N-(β-oxyethyl)-N,N′,N′-triacetic acid 1,3-Diaminopropanetetraacetic acid, Triethylenetetraminehexaacetic acid, Propylenediaminetetraacetic acid, Nitrilotriacetic acid, Nitrilotripropionic acid, Cyclohexanediaminetetraacetic acid, 1,3-Diamino-2-propanoltetraacetic acid, Methyliminodiacetic acid, Iminodiacetic acid, Hydroxyliminodiacetic acid, Dihydroxyethylglycine ethyl ether diaminetetraacetic acid, Glycol ether diaminetetraacetic acid, Ethylenediaminetetrapropionic acid, Ethylenediaminedipropionic acid, Phenylenediaminetetraacetic acid, 2-Phosphonobutane-1,2,4-triacetic acid, 1,3-Diaminopropanol-N,N,N′,N′-tetramethylenephosphonic acid, Ethylenediamine-N,N,N′,N′-tetramethylenephosphonic acid, 1,3-Propylenediamine-N,N,N′,N′-tetramethylenephosphonic acid, 1-Hydroxyethylidene-1,1′-diphosphonic acid, etc. These compounds may form any salt of sodium, potassium, lithium and ammonium. In these compounds, the iron (III) complex salts of ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, 1,3-diaminopropanetetraacetic acid, and methyliminodiacetic acid are preferred from the viewpoint of high bleaching power. These ferric ion complex salts may be used in the form of a complex salt or a ferric ion complex salt may be formed in solution using (a) a ferric salt such as ferric sulfate, ferric chloride, ferric nitrate, ammonium iron (III) sulfate and ferric phosphate and (b) a chelating agent such as an aminopolycarboxylic acid, an aminopolyphosphonic acid and a phosphonocarboxylic acid. One or more complex salts may be used in the form of complex salts, or alternatively one or more ferric salts can be used to form complex salts in solution by using ferric salts and a chelating agent. Further, one or more chelating agents may be used. In either case, a chelating agent may be used in excess of the stoichiometric amount required to form a ferric ion complex salt. Of iron complex salts, aminopolycarboxylic acid iron complex salts are preferred, and the amount used is about 0.01 to 1.0 mol/l, preferably about 0.05 to 0.50 mol/l. Further, if desired, the bleaching solution or the bleach-fix solution may contain a bleach accelerating agent. Specific examples of useful bleach accelerating agents include compounds having a mercapto group or a disulfide group described, for example, in U.S. Patent 3,893,858, West German Patents 1,290,812 and 2,059,988, Japanese Patent Application (OPI) Nos. 32736/78, 57831/78, 37418/78, 65732/78, 72623/78, 95630/78, 95631/78, 104232/78, 124424/78, 141623/78 and 28426/78 and Research Disclosure, No. 171129 (July, 1978); thiazolidine derivatives as described in Japanese Patent Application (OPI) No. 140129/75; thiourea derivatives described in Japanese Patent Publication No. 8506/70, Japanese Patent Application (OPI) Nos. 20832/77 and 32735/78 and U.S. Patent 3,706,561; iodides described in West German Patent 1,127,715 and Japanese Patent Application (OPI) No. 16235/83; polyethylene oxides described in West German Patents 966,410 and 2,748,430; polyamine compounds described in Japanese Patent Publication No. 8836/70; and iodide and bromide ions and compounds described in Japanese Patent Application (OPI) Nos. 42434/74, 59644/74, 94927/78, 35727/79, 26506/80 and 163940/83. Of these, compounds having a mercapto group or a disulfide group are preferred in view of their high acceleration effect, and, in particular, compounds described in U.S. Patent 3,893,858, West German latent 1,290,812 and Japanese Patent Application (OPI) No. 95630/78 are preferred. It is preferred that the bleach liquid or blix liquid for use in this invention contains a rehalogenating agent such as a bromide (e.g., potassium bromide, sodium bromide or ammonium bromide), a chloride (e.g., potassium chloride, sodium chloride or ammonium chloride), and an iodide (e.g., ammonium iodide). Also, if necessary, the bleach liquid or blix liquid may further contain a corrosion inhibitor such as an inorganic acid or an organic acid having a pH buffering capability, or the alkali metal salt or ammonium salt thereof, such as boric acid, borax, sodium metaborate, acetic acid, sodium acetate, sodium carbonate, potassium carbonate, phosphorus acid, phosphoric acid, sodium phosphate, citric acid, sodium citrate or tartaric acid, or ammonium nitrate or guanidine. As the fixing agent which is used for the fix or the blix in this invention, there are thiosulfates such as sodium thiosulfate or ammonium thiosulfate; thiocyanates such as sodium thiocyanate or ammonium thiocyanate; thioether compounds such as ethylenebisthioglycolic acid or 3,6-dithia-1,8-octanediol; and water-soluble silver halide dissolving agents such as thioureas. They may be used solely or as a mixture thereof. Furthermore, for the blix processing in this invention, a specific blix liquid composed of a combination of a fixing agent and a large amount of a halide such as potassium iodide, as described in Japanese Patent Application (OPI) No. 155354/80 can be also used. In the present invention, it is preferred to use a thiosulfate, particularly ammonium thiosulfate, in the fixing bath or bleach-fixing bath as a fixing agent. Preferably the amount of fixing agent used per l is in the range of about 0.3 to 2 mol, more preferably about 0.5 to 1.0 mol. Preferably, the pH range of the bleach-fix solution or fixer in the present invention is about 3 to 10, more preferably about 5 to 9. When the pH is lower, although the desilvering ability may be improved, deterioration of the solution and production of leuco compound from cyanine dyes are increased. By contrast, when the pH is higher, desilvering is slowed, and staining is liable to occur. To adjust the pH, for example, hydrochloric acid, sulfuric acid, nitric acid, acetic acid, a bicarbonate, ammonia, caustic potash, caustic soda, sodium carbonate or potassium carbonate is added as required. Further, the bleach-fix solution can contain a fluorescent brightening agent, an antifoaming agent, a surface active agent, a polyvinyl pyrrolidone and an organic solvent such as methanol. The bleach-fix solution or the fixing solution in the present invention contains, as a preservative, a sulfite ion-releasing compound such as a sulfite (e.g., sodium sulfite, potassium sulfite and ammonium sulfite), a bisulfite (e.g., ammonium bisulfite, sodium bisulfite and potassium bisulfite) and a metabisulfite (e.g., potassium metabisulfite, sodium metabisulfite and ammonium metabisulfite). Preferably, these compounds are present in an amount of about 0.02 to 0.50 mol/l, more preferably about 0.04 to 0.40 mol/l in terms of sulfite ions. Although, generally, as a preservative a sulfite is added, for example, ascorbic acid, a carbonyl bisulfite adduct or a carbonyl compound also can be used. Further, for example, a buffering agent, a fluorescent brightening agent, a chelating agent and an antimildew agent can be added, if required. The washing step of the present invention is now described in detail. The term "washing step" as used herein includes processes which can be substituted for a conventional water washing step, such as a rinsing process and a water washing promoting process. In the present invention, instead of the usual "washing process", a "stabilizing process", for example, without a substantial washing step can be used alone. Thus, in the present invention, the term "washing process" is broad enough to include any of the above processes. Since the amount of washing water or of stabilizing solution used in the present invention varies depending on the number of baths of a multicountercurrent washing process, and the quantity of components of the photosensitive material carried over from the preceding bath, although it is hard to specify the quantity, it is generally sufficient if the bleaching or fixer components in the final bath or the bath after the bath having a fixing function is decreased to about 1 x 10⁻⁴ times the concentration of these components in the original bath. For example, in the case of three-tank countercurrent washing, it is preferred that the washing water quantity be at least about 1,000 mℓ, more preferably at least about 5,000 mℓ, per m² of the photosensitive material. When it is desired to save water, the quantity used is about 100 to 1,000 mℓ per m² of the photosensitive material. The washing process or stabilizing process temperature is typically about 15 to 45°C, preferably about 20 to 35°C. For the purpose of preventing precipitation or stabilizing the washing water, various known compounds may be added to the washing step bath. For example, an inorganic phosphoric acid, a chelating agent such as aminocarboxylic acids and organic phosphonic acids, a fungicide or an antifungal agent for preventing bacteria, algae or mold from occurring, as described, for example, in Journal of Antibact. Antifung. Agents, Vol. 11, No. 5, pages 207 to 223 (1983), and by Hiroshi Horiguchi in Bokin Bobai no Kagaku, a metal salt such as a magnesium salt and an aluminum salt, an alkali metal salt, an ammonium salt, and a surface active agent for preventing uneven washing or drying load may be added, if desired. Further, compounds described, for example, by West in Photographic Science and Engineering, Vol. 6, pages 344 to 359 (1965) may be added. The present invention is particularly useful when a chelating agent, a fungicide and an antifungal agent are added to washing water, and water is greatly saved by multi-countercurrent washing using two or more tanks. The present invention is also particularly useful when instead of the usual washing stage, a multi-countercurrent stabilizing process ("stabilizing process") as described in Japanese Patent Application (OPI) No. 8543/82 is used. In these cases, it is sufficient if the bleaching or fixing components in the final bath are descreased to about 5 × 10⁻² or below, preferably about 1 × 10⁻², times the original concentration of these components. It is also effective to use only water from which calcium ions and magnesium ions are substantially removed, such as distilled water and deionized water, to greatly reduce the amount of water used. For the purpose of stabilizing the image, various compounds can be optionally added to the stabilizing bath. For example, various buffering agents (e.g., borates, metaborates, borax, phosphates, carbonates, potassium hydroxide, sodium hydroxide, ammonia water, monocarboxylic acids, dicarboxylic acids and polycarboxylic acids that are used in combination) for adjusting the film pH (e.g., to a pH of about 3 to 8) and aldehydes such as formaldehyde can be used. Further, chelating agents (e.g., inorganic phosphoric acids, aminopolycarboxylic acids, organic phosphonic acids, aminopolyphosphonic acids and phosphonocarboxylic acids), fungicides (e.g., thiazole tungicides, isothiazole fungicides, halogenated phenols, sulfanilamide and benzotriazole), surface active agents, fluorescent brightening agents, and hardening agents can be used, and two or more of them can be used in combination. To improve the stability of the color image formed, it is preferred to add, as a film pH adjusting agent to the stabilization bath, an ammonium salt such as ammonium chloride, ammonium nitrate, ammonium sulfate, ammonium phosphate, ammonium sulfite and ammonium thiosulfate. It is also preferred that a process to decrease the amount of Ca or Mg as described in Japanese Patent Application No. 131632/86 is employed to improve the stability of washing water. When the amount of washing water or a stabilizing solution is required to be reduced, it is preferred to introduce part or all of the overflow of washing water into the preceding bleach-fix bath or fixing bath, to decrease the amount of discharge. In continuous processing, the use of replenishing solutions can prevent the solution compositions from fluctuating, thereby securing consistent results. The replenishing amount can be decreased to half of the standard replenishing amount or can be further decreased to reduce costs. Each processing bath may be provided, as desired, with any conventional processing apparatus without limitation, including a heater, a temperature sensor, a level sensor, a circulating pump, a filter, a floating lid, a squeegee, a nitrogen agitation equipment and an air agitation equipment. The present method can be applied to any processing method in which a color developing solution is used. For example, the present method can be applied to development of color paper, color reversal paper, color positive film, color direct positive film, color negative film and color reversal film, and is particularly advantageous when applied to the development of color paper and color reversal paper. Although the silver halide emulsion of the photographic material used in the present invention may have any halogen composition, including silver bromoiodide, silver bromide, silver chlorobromide and silver chloride, when rapid processing or a low replenishment processing is carried out, it is preferred to use a silver chloride emulsion or a silver chlorobromide emulsion containing at least about 60 mol%, more preferably about 80 to 100 mol%, of silver chloride. When high sensitivity is required, and fogging during the production, storage and/or processing is required to be particularly reduced, it is preferred to use a silver bromide emulsion or a silver chlorobromide emulsion containing at least about 50 mol%, more preferably at least about 70 mol%, of silver bromide. If the content of silver bromide is about 90 mol% or over, rapid processing becomes difficult. It is at times preferred to use a technique for accelerating development, for example, using a development accelerator such as a developer, a fogging agent or a silver halide solvent described later, since such a technique makes development accelerate to some degree without being restricted by the content of silver halide. In any case, it is preferred that the emulsion does not contain a large amount of silver iodide, and it is sufficient that the amount of silver bromide is at most about 3 mol%, in silver halide emulsions used for color paper. In the case of color photographic films (e.g., negative films and reversal films), silver bromoiodide and silver bromochloroiodide emulsions are preferred, in which the content of silver bromide is preferably about 3 to 15 mol%. In the silver halide grains contained in these emulsions, the phase of the core may differ from the phase of the surface layer; a multiple phase structure having a junction structure may be used; or the entire grain may be composed of a uniform phase. These grains may be present as a mixture. Average grain size of silver halide grains (the grain size being defined as grain diameter if the grain has a spherical or a nearly spherical form and as a length of the edge if the grain has a cubic form, and being averaged based on projected areas of the grains, plate like grain is calculated as a spherical form) is preferably from 0.1 µm to 2 µm, and particularly from 0.15 µm to 1.5µm. Grain size distribution may be either narrow or broad. A so-called monodispersed silver halide emulsion can be employed in the present invention. The degree of monodispersity is indicated using a value, i.e., a coefficient of variation, which is obtained by dividing the standard deviation derived from grain size distribution curve of silver halide by the average grain size, and the coefficient of variation is preferably 20% or less and particularly 15% or less. Further, in order to achieve the desired gradation of the light-sensitive material, two or more monodispersed silver halide emulsions (preferably having the above described coefficient of variation) which have different grain sizes from each other can be mixed in one emulsion layer or can be coated in the form of superimposed layers which have substantially the same spectral sensitivity. Moreover, two or more polydispersed silver halide emulsions or combinations of a monodispersed emulsion and a polydispersed emulsion may be employed in a mixture or in the form of superimposed layers. Silver halide grains which can be used in the present invention may have a regular crystal structure, for example, a cubic, octahedral, dodecahedral or tetradecahedral structure, an irregular crystal structure, for example, a spherical structure, or a composite structure thereof. Further, tabular silver halide grains can be used. Particularly, a silver halide emulsion wherein tabular silver halide grains having a ratio of diameter/thickness of not less than 5, preferably not less than 8, account for at least 50% of the total projected area of the silver halide grains present can be employed. In addition, mixtures of silver halide grains having different crystal structures may be used. These silver halide emulsions may be those of surface latent image type in which latent images are formed mainly on the surface thereof, those of internal latent image type in which latent images are formed mainly in the interior thereof. Photographic emulsions as used in the present invention can be prepared in any suitable manner, for example, by the methods as described in P. Glafkides, Chimie et Physique Photographique, Paul Montel (1967), G.F. Duffin, Photographic Emulsion Chemistry, The Focal Press (1966), V.L. Zelikman et al., Making and Coating Photographic Emulsion, The Focal Press (1964), and Research Disclosure, Vol. 170, Item No. 176, 43 (I) (December, 1978). That is, any of an acid process, a neutral process or an ammonia process can be employed. Soluble silver salts and soluble halogen salts can be reacted by techniques such as a single jet process, a double jet process, and a combination thereof. In addition, there can be employed a method (so-called reversal mixing process) in which silver halide grains are formed in the presence of an excess of silver ions. A conversion method wherein a halogen salt which can form more insoluble silver halide is added may also be used. As one system of the double jet process, a so-called controlled double jet process in which the pAg in a liquid phase where silver halide is formed is maintained at a predetermined level can be employed. This process can prepare a silver halide emulsion in which the crystal form is regular and the particle size is nearly uniform. Further, an emulsion prepared by a conversion process can be used, by which a silver halide already formed is converted to a silver halide whose solubility product is smaller, before completing the formation of the silver halide grains. Alternatively, an emulsion which is subjected to similar halogen conversion after completing the formation of the silver halide grains can also be used. During the step of formation or physical ripening of silver halide grains, cadmium salts, zinc salts, lead salts, thallium salts, iridium salts or complex salts thereof, rhodium salts or complex salts thereof, iron salts or complex salts thereof, may be allowed to coexist. After the formation of silver halide grains, silver halide emulsions are usually subjected to physical ripening, removal of soluble salts and chemical ripening and then employed for coating. Known silver halide solvents (for example, ammonia, potassium thiocyanate, and thioethers and thione compounds as described in U.S. Patent 3,271,157, Japanese Patent Application (OPI) Nos. 12360/76, 82408/78, 144319/78, 100717/79, 155828/79) can be employed during the step of formation, physical ripening or chemical ripening of silver halide. For removal of soluble silver salts from the emulsion after physical ripening, for example, a noodle washing process, a flocculation process or an ultrafiltration process, can be employed. The silver halide emulsions in materials processed by the present invention can be sensitized, e.g., by any of a sulfur sensitization method that uses activated gelatin and a compound (e.g., thiosulfates, thioureas, mercapto compounds and rhodanine) containing sulfur capable of reacting with silver; a reduction sensitization method that uses a reducing material (e.g., stannous salts, amines, hydrazine derivatives, formamidinesulfinic acid and silane compounds); and a noble metal sensitization method that uses a metal compound (e.g., gold complex salts, and complex salts of metals of Group VIII of the Periodic Table such as Pt, Ir, Pd, Rh and Fe), either alone or in combination. The blue-sensitive, green-sensitive and red-sensitive emulsions used in the present invention are typically spectrally sensitized using methine dyes and other dyes to have the respective color sensitivities. The dyes used for the purpose include cyanine dyes, merocyanine dyes, complex cyanine dyes, complex merocyanine dyes, holopolar cyanine dyes, hemicyanine dyes, styryl dyes, and hemioxonol dyes. Particularly useful dyes are dyes belonging to cyanine dyes, merocyanine dyes and complex merocyanine dyes. For these dyes can be applied nuclei which are usually utilized as base heterocyclic nuclei. Examples of these nuclei are pyrroline nuclei, oxazoline nuclei, thiazoline nuclei, pyrrole nuclei, oxazole nuclei, thiazole nuclei, selenazole nuclei, imidazole nuclei, tetrazole nuclei and pyridine nuclei; the nuclei formed by fusing an alicyclic hydrocarbon ring to the aforesaid nuclei or the nuclei formed by fusing an aromatic hydrocarbon ring to the aforesaid nuclei, i.e., indolenine nuclei, benzindolenine nuclei, indole nuclei, benzoxazole nuclei, naphthoxazole nuclei, benzothiazole nuclei, naphthothiazole nuclei, benzoselenazole nuclei, benzimidazole nuclei and quinone nuclei. These nuclei may have a substituent on the carbon atom thereof. For the merocyanine dyes or complex merocyanine dyes can be applied 5- or 6-membered heterocyclic nuclei such as pyrazolin-5-one nuclei, thiohydantoin nuclei, 1-thiooxazolidine-2,4-dione nuclei, thiazolidine-2,4-dione nuclei, rhodanine nuclei or thiobarbituric acid nuclei, as nuclei having a ketomethylene structure. The sensitizing dyes described above may be used singly or as a combination thereof, and a combination of sensitizing dyes is frequently used for super color sensitization. Useful sensitizing dyes are disclosed in Research Disclosure, Vol. 176, Item No. 17643 (IV) (December, 1978), U.S. Patents 2,688,545, 2,977,229, 3,397,060, 3,522,052, 3,527,641, 3,617,293, 3,628,964, 3,666,480, 3,672,898, 3,679,428, 3,703,377, 3,769,301, 3,814,609, 3,837,862 and 4,026,707, British Patents 1,344,281 and 1,507,803, Japanese Patent Publication Nos. 4936/68 and 12375/78 and Japanese Patent Application (OPI) Nos. 10618/77 and 109925/77. In addition to a sensitizing dye, the emulsion can contain a dye that does not itself have a spectral sensitizing effect, or a material that does not substantially absorb visible light, but that exhibits a super-sensitizing effect. These sensitizing dyes may be added at the time of grain formation, before or after chemical sensitization, at the time of chemical sensitization or at the time of coating. When a sensitizing dye is added at the time of grain formation, not only is the adsorption enhanced, but it is also effective for control of the crystalline configuration of grains or the control of the grain structure. When a sensitizing dye is added at the time of chemical sensitization, not only is the adsorption enhanced, but it is also effective to control the sites of chemical sensitization and to prevent crystals from being distorted. These methods of addition are particularly useful when an emulsion contains a high silver halide content, and are also particularly useful when applied to grains in which the grain surface is increased in silver bromide or silver iodide content. It is preferable that these couplers are incorporated into photographic light-sensitive materials and these couplers are rendered diffusion resistant by means of containing a ballast group or being polymerized. It is also preferred that the coupling active position of these couplers is substituted with a group capable of being released (2-equivalent couplers) than with a hydrogen atom (4-equivalent couplers) from the standpoint that the coating amount of silver is reduced. Further, couplers which form dyes having an appropriate diffusibility, non-color-forming couplers, or couplers capable of releasing development inhibitors (DIR couplers) or development accelerators accompanying with the coupling reaction can also be employed. Typical examples of oil protect type acylacetamide series couplers are described in U.S. Patents 2,407,210, 2,875,057 and 3,265,506. In the present invention, the use of 2-equivalent yellow couplers is preferred, and typical examples thereof are oxygen atom coupling-off yellow couplers described, for example, in U.S. Patents 3,408,194, 3,447,928, 3,933,501 and 4,022,620; and nitrogen atom coupling-off yellow couplers described, for example, in Japanese Patent Publication No. 10739/80, U.S. Patents 4,401,752, 4,326,024, Research Disclosure, No. 18053 (April, 1979), British Patent 1,425,020, and West German Offenlegungsschriften 2,219,917, 2,261,361, 2,329,587 and 2,433,812. α-Pivaloylacetanilide couplers are excellent in fastness, particularly fastness to light, of the developed color dye, while α-benzoylacetanilide couplers can provide a high developed color density. Magenta couplers used in the present invention include oil protected indazolone type couplers, cyanoacetyl type couplers, and preferably 5-pyrazolone type couplers and pyrazoloazole type couplers such as pyrazolotriazoles. Of 5-pyrazolone type couplers, those substituted with an arylamino group or an acylamino group at the 3-position thereof are preferred in view of hue and a color density of dyes formed. Typical examples thereof are described in U.S. Patents 2,311,082, 2,343,703, 2,600,788, 2,908,573, 3,062,653, 3,152,896 and 3,936,015. 2-Equivalent 5-pyrazolone type couplers are preferably used. Particularly, nitrogen atom-releasing groups as described in U.S. Patent 4,310,619 and arylthio groups as described in U.S. Patent 4,351,897 are preferred as releasing groups. Further, 5-pyrazolone type couplers having a ballast group as described in European Patent 73,636 are advantageous because they provide a high color density. Examples of pyrazoloazole type couplers include pyrazolobenzimidazoles as described in U.S. Patent 3,369,879, and preferably pyrazolo[5,1-c][1,2,4]triazoles as described in U.S. Patent 3,725,067, pyrazolotetrazoles as described in Research Disclosure, RD No. 24220 (June, 1984) and Japanese Patent Application (OPI) No. 33552/85 and pyrazolopyrazoles as described in Research Disclosure, RD No. 24230 (June, 1984) and Japanese Patent Application (OPI) No. 43659/85. Imidazo[1,2-b]pyrazoles as described in European Patent 119,741 are preferred, and pyrazolo[1,5-b][1,2,4]triazoles as described in European Patent 119,860 are particularly preferred in view of less yellow subsidiary absorption and light fastness of dyes formed. As cyan couplers used in the present invention, oil protected naphthol type and phenol type couplers are exemplified. Typical examples thereof include naphthol type couplers as described in U.S. Patent 2,474,293 and preferably oxygen atom-releasing type 2-equivalent naphthol type couplers as described in U.S. Patents 4,052,212, 4,146,396, 4,228,233 and 4,296,200. Specific examples of phenol type couplers are described in U.S. Patents 2,369,929, 2,801,171, 2,772,162 and 2,895,826. Cyan couplers fast to humidity and temperature are preferably used in the present invention. Typical examples thereof include phenol type cyan couplers having an alkyl group having more carbon atoms than a methyl group at the meta-position of the phenol nucleus as described in U.S. Patent 3,772,002, 2,5-diacylamino-substituted phenol type couplers as described in U.S. Patents 2,772,162, 3,758,308, 4,126,396, 4,334,011 and 4,327,173, West German Patent Application (OLS) No. 3,329,729 and European Patent 121,365, and phenol typc couplers having a phenylureido group at the 2-position thereof and an acylamino group at the 5-position thereof as described in U.S. Patents 3,446,622, 4,333,999, 4,451,559 and 4,427,767. Particularly, in the present method of processing, by using color materials containing at least one of cyan couplers represented by the general formulae (C-I) and (C-II) given below, fogging is reduced and good photographic characteristics can be obtained. The improvement obtained when processing these materials is unexpectedly significant and surprising. wherein R³¹ represents an alkyl group, a cycloalkyl group, each having 1 to 32 carbon atoms, an arylamino group having 6 to 32 carbon atoms, an amino group or a heterocyclic ring group including a 5- or 6-membered ring containing at least one hetero atom of S, N and O; R³² represents an alkyl group having 1 to 32 carbon atoms or an aryl group having 6 to 32 carbon atoms; R³³ represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 32 carbon atoms or an alkoxy group having 1 to 32 carbon atoms, and R³³ may be linked with R³² to form a ring; and Z¹ represents a hydrogen atom, a halogen atom or a coupling-off group capable of being cleaved by a reaction of the coupler with the oxidation product of an aromatic primary amine color developing agent; wherein R³⁴ represents an alkyl group, a cycloalkyl group each having 1 to 32 carbon atoms, an aryl group having 6 to 32 carbon atoms or a heterocyclic group including a 5- or 6-membered ring containing at least one hetero atom or S, N and O; R³⁵ represents an alkyl group having at least 2 carbon atoms; R³⁶ represents a hydrogen atom, a halogen atom or an alkyl group having 1 to 32 carbon atoms; and Z² represents a hydrogen atom, a halogen atom or a coupling-off group capable of being cleaved by a reaction of the coupler with the oxidation product of an aromatic primary amine color developing agent.

Specific examples of cyan couplers represented by general formulae (C-I) and (C-II) are given below: Cyan couplers represented by general formulae (C-I) and (C-II) can be synthesized, for example, by the methods described in Japanese Patent Application (OPI) No. 166956/84 and Japanese Patent Publication No. 11572/74. Couplers that produce developed color dyes exhibiting suitable diffusibility can also be used to improve graininess. Examples of such dye diffusing couplers are described in U.S. Patent 4,366,237 and British Patent 2,125,570; examples of magenta couplers are described in European Patent 96,570; and examples of yellow, magenta or cyan couplers are described in West German Offenlegungsschrift No. 3,234,533. Dye-forming couplers and the above special couplers may form a dimer or more higher polymer. Typical examples of polymerized dye-forming couplers are described in U.S. Patents 3,451,820 and 4,080,211. Specific examples of polymerized magenta couplers are described in British Patent 2,102,173 and U.S. Patent 4,367,282. To satisfy the properties required for a photographic material, two types of the above-described couplers can be used in the same photosensitive layer, or the same compound can be introduced into two or more layers. The couplers used in the present invention are incorporated into a photosensitive material by an oil-in-water dispersion method. In the oil-in-water dispersion method, the coupler is dissolved in a high boiling organic solvent having a boiling point of at least 175°C and/or a so-called auxiliary solvent having low boiling point, and then finely dispersed in water or an aqueous medium such as an aqueous gelatin solution in the existence of a surface active agent as the solution thereof. Examples of the high boiling point organic solvent are described in U.S. Patent 2,322,027. The formation of the dispersion may be accomplished with phase inversion. The auxiliary solvent may be removed or reduced by distillation, noodle washing, or ultrafiltration, before the dispersion of the coupler is coated. Specific examples of the high boiling point organic solvent which is used for dispersing the couplers in this invention include phthalic acid esters (e.g., dibutyl phthalate, dicyclohexyl phthalate, di-2-ethylhexyl phthalate or decyl phthalate), phosphoric acid esters or phosphonic acid esters (e.g., triphenyl phosphate, tricresyl phosphate, 2-ethylhexyldiphenyl phosphate, tricyclohexyl phosphate, tri-2-ethylhexyl phosphate, tridecyl phosphate, tributoxyethyl phosphate, trichloropropyl phosphate or di-2-ethylhexylphenylphosphate), benzoic acid esters (e.g., 2-ethylhexyl benzoate, dodecyl benzoate or 2-ethylhexyl-p-hydroxy benzoate), amides (e.g., diethyldecanamide or N-tetradecylpyrazolidone), alcohols or phenols (e.g., isostearyl alcohol or 2,4-di-tert-amylphenol), aliphatic carboxylic acid esters (e.g., dioctyl azerate, glycerol tributyrate, isostearyl lactate or trioctyl citrate), aniline derivatives (e.g., N,N-dibutyl-2-butoxy-5-tert-octylaniline), hydrocarbons (e.g., paraffin, dodecylbenzene or diisopropylnaphthalene). In this invention, an organic solvent having a low boiling point of at least about 30°C, and preferably from about 50°C to about 160°C, can be used as auxiliary solvent as described above. Specific examples of the low boiling organic solvent are ethyl acetate, butyl acetate, ethyl propionate, methyl ethyl ketone, cyclohexanone, 2-ethoxyethyl acetate and dimethylformamide. The steps and effects of the latex dispersion method and specific examples of latex for impregnation are described in U.S. Patent 4,199,363, West German Patent Application (OLS) Nos. 2,541,274 and 2,541,230. Generally, the amount of couplers used is about 0.001 to 1 mol per mol of a photosensitive silver halide. Preferably in the case of a yellow coupler the amount is about 0.01 to 0.5 mol per mol of a photosensitive silver halide; in the case of a magenta coupler the amount is about 0.003 to 0.3 mol per mol of a photosensitive silver halide; and in the case of a cyan coupler the amount is about 0.002 to 0.3 mol per mol of a photosensitive silver halide. The photographic material processed by the present invention may contain, as a color fogging preventing agent or a color mixing preventing agent, any of conventional hydroquinone derivatives, aminophenol derivatives, amines, gallic acid derivatives, catechol derivatives, ascorbic acid derivatives, colorless couplers and sulfonamidophenol derivatives. In the photosensitive material processed by the present invention, a known fading preventing agent can be used. Typical examples of organic fading preventing agents include hydroquinones, 6-hydroxychromans, 5-hydroxycoumarans, spirochromans, p-alkoxyphenols, hindered phenols including bisphenols, gallic acid derivatives, methylenedioxybenzenes, aminophenols, hindered amines and ether or ester derivatives of these compounds obtained by silylating or alkylating the phenolic hydroxyl group of these compounds. Further, metal complexes such as (bissalicylaldoximato)nickel complex and (bis-N,N-dialkyldithiocarbamato)nickel complexes can be used. To prevent the yellow dye image from being deteriorated by heat, humidity or light, compounds having both a hindered amine structure and a hindered phenol structure in the same molecule as described in U.S. Patent 4,268,593 give good results. To prevent the magenta dye image from being deteriorated, particularly by light, spiroindanes described in Japanese Patent Application (OPI) No. 159644/81 and hydroquinone-diether-substituted or hydroquinone-monoether-substituted chromans described in Japanese Patent Application (OPI) No. 89835/80 are preferably used. To improve shelf stability and particularly light fastness of the cyan image, a benzotriazole type ultraviolet absorbent is also preferably used. This ultraviolet absorbent may be coemulsified with a cyan coupler. The coating amount of the ultraviolet absorbent is an amount sufficient to provide the cyan dye image with light stability, not so high as to cause the unexposed part (white part) of a color photographic paper to yellow. The coating amount is generally in the range of about 1 x 10⁻⁴ mol/m² to 2 x 10⁻³ mol/m², more preferably about 5 x 10⁻⁴ mol/m² to 1.5 x 10⁻³ mol/m². In the photosensitive layer structure of a typical color paper, one and preferably both, of the layers adjacent to a cyan coupler-containing red-sensitive emulsion layer contain an ultraviolet absorbent. When an ultraviolet absorbent is added to an intermediate layer between a green-sensitive layer and a red-sensitive layer, it may be coemulsified with a color mixing preventing agent. When an ultraviolet absorbent is added to a protective layer, another protective layer as an outer-most layer may be applied. In this protective layer, a matting agent having any desired particle diameter may be included. In the photosensitive material to which the present invention is applied, the ultraviolet absorbent can be added to a hydrophilic colloid layer. In the photosensitive material used in the present invention, for the purpose of prevention of irradiation or halation or for other purposes, a water-soluble dye may be included as a filter dye in a hydrophilic colloid layer. Oxonol type dyes, anthraquinone type dyes or azo type dyes are preferably used for these purposes, and oxonol dyes that absorb green light and red light are particularly preferred. The photographic emulsion layer or other hydrophilic colloid layers of the photosensitive material used in the present invention may contain stilbene type brightening agents, triazine type brightening agents, oxazole type brightening agents or cumarin type brightening agents. Water-soluble brightening agents may be used or water-insoluble brightening agents in the form of a dispersion may be used. The present invention can be used to process a multilayer multicolor photographic material having at least two different spectral sensitivities on a base. Generally, a multilayer color photographic material has at least one red-sensitive emulsion layer, at least one green-sensitive emulsion layer and at least one blue-sensitive emulsion layer on a base. The order of the arrangement of these layers may be varied as desired. Each of these emulsion layers may be composed of two or more emulsion layers differing in sensitivity, and a non-photosensitive layer may be present between two or more emulsion layers having the same sensitivity. It is preferred that the photosensitive material used in the present invention, in addition to a silver halide emulsion layer, have suitable conventional auxiliary layers such as a protective layer, an intermediate layer, a filter layer, an antihalation layer and a backing layer. As a binder or a protective colloid that can be used in the emulsion layer and the intermediate layers of the photosensitive material used in the present invention, gelatin is advantageously used, but other hydrophilic colloids can be used. For example, proteins such as gelatin derivatives, graft polymers of gelatin with other polymers, albumin and casein; cellulose derivatives such as hydroxyethyl celluloses, carboxymethyl celluloses and cellulose sulfates, sugar derivatives such as sodium alginate and starch derivatives; and various synthetic hydrophilic polymers such as homopolymers or copolymers, for example, polyvinyl alcohols, polyvinyl alcohol partial acetals, poly-N-vinylpyrrolidones, polyacrylic acids, polymethacrylic acids, polyacrylamides, polyvinylimidazoles and polyvinylpyrazoles can be used. It is particularly useful to use acrylic acid-modified polyvinyl alcohols in a protective layer when an emulsion having a high silver halide content is to be processed by rapid processing. Useful gelatins include lime-processed gelatins, acid-processed gelatins and enzyme-processed gelatins as described in Bull. Soc. Sci. Phot. Japan, No. 16, page 30 (1966). Hydrolyzates and enzymolyzates of gelatin can also be used. To the photosensitive material processed by the present invention may be added, in addition to the above additives, various conventional stabilizers, stain preventives, developers or their precursors, the abovementioned development accelerators and their precursors, lubricants, mordants, matting agents, antistatic agents, plasticizers or other additives. Typical examples of these additives are described in Research Disclosure, No. 17643 (December, 1978) and Research Disclosure, No. 18716 (November, 1979). In photographic papers, the support is preferably a reflective base that increases the reflectivity and makes the dye image formed in a silver halide emulsion layer clear. Such reflective bases include a base coated with a hydrophobic resin containing a light reflecting material dispersed therein such as titanium oxide, zinc oxide, calcium carbonate and calcium sulfate. For example, baryta paper, polyethylene-coated paper, polypropylene type synthetic paper, a transparent base (e.g., glass plate, film of polyesters such as polyethylene terephthalate, cellulose triacetate and cellulose nitrate, polyamide film, polycarbonate film and polystyrene film) having a reflective layer or a reflecting material can be suitably selected according to the application. The invention will now be explained in greater detail and with reference to the following Examples. Unless otherwise indicated, all parts, percents and ratios are by weight. EXAMPLE 1 The following color developing solution was prepared. Color Developing Solution : Compound (A) Given in Table 1 Compound (B) Given in Table 1 Sodium sulfite 0.2 g Potassium carbonate 30 g EDTA·2Na 1 g Sodium chloride 1.5 g 4-Amino-3-methyl-N-ethyl-N-[β-(methanesulfonamido)ethyl]-p-phenylenediamine sulfate 5.0 g Brightener (4,4′-diaminostilbene UVITEX-CK, manufactured by Ciba-Geigy) 3.0 g Water to make 1,000 mℓ pH adjusted to 10.05 using KOH and H₂SO₄ The thus prepared samples (Nos. 1 to 20) of color developing solutions were introduced into open test tubes such that the opening ratio (opening area/sample volume) was 0.06 cm⁻¹, and were allowed to stand at 35°C for 4 weeks. Thereafter, the amount lost due to evaporation was replaced with distilled water, and the remaining ratio of the aromatic primary amine color developing agent was determined by liquid chromatography. As is apparent from Table 1, in contrast when only hydroxylamine or diethylhydroxylamine (Sample Nos. 1 and 2) was used, when compounds such as triethanolamine, polyethyleneimine or sodium sulfite were also present, the ratio of the developing agent remaining could be increased, although not to a satisfactory extent (Sample Nos. 3, 4 and 5). However, as is apparent from Sample Nos. 9 to 20, when compounds represented by general formula (Ia) were added to the developing solution, the ratio of the developing agent remaining was remarkably improved, demonstrating the improvement in the preservability of the color developing solution. Particularly, as is apparent from Sample Nos. 11 and 12, the combination of a compound represented by general formula (Ia) and hydroxylamine compound II-(5) remarkably improved preservability. EXAMPLE 2 The color developing solutions used in Example 1 were used. In the same manner as in Example 1, the remaining ratio of the aromatic primary amine color developing agent was determined. The results are given in Table 2. As is apparent from Table 2, in contrast to the developing solution containing only hydroxylamine or diethylhydroxylamine (Sample Nos. 1 and 2), when compounds such as triethanolamine, polyethyleneimine or sodium sulfite were also prevent, the ratio of the developing agent remaining could be increased, but to an insufficient extent (Sample Nos. 3, 4 and 5). However, when compounds according to the invention were used, the preservability of the developing agent could be improved (Sample Nos. 9 to 20), and in particular, when the hydroxylamine II-(33) was added, the preservability was remarkably improved (Sample Nos. 11 and 12). These results demonstrate the surprising superiority of the invention combination, in contrast to triethanolamine, sodium sulfite and polyethyleneimine, in improving the stability of the color developing agent. EXAMPLE 3 A paper base having opposite surfaces laminated with polyethylene was coated with layers having compositions shown in Table B below, to prepare a multilayer color photographic paper. The coating composition of each layer was prepared as described below. The structures of the couplers, the dye stabilizers, and other compounds used in the coating liquids are given below. Preparation of the First Coating Liquid 27.2 mℓ of ethyl acetate and 7.9 mℓ of solvent (c) were added to 19.1 g of yellow coupler (a) and 4.4 g of dye stabilizer (b) to dissolve them, and the solution was emulsified and dispersed into 185 mℓ of a 10% aqueous gelatin solution containing 8 mℓ of a 10% aqueous solution of sodium dodecylbenzenesulfonate. Separately, a blue spectral sensitizing dye shown below was added to a silver chlorobromide emulsion (silver bromide: 1 mol%, Ag content: 70 g/kg) in an amount of 5.0 × 10⁻⁴ mol per mol of silver chlorobromide to prepare 90 g of a blue-sensitive emulsion. The emulsified dispersion and the emulsion were mixed and dissolved to prepare the first layer coating liquid, with a gelatin concentration adjusted to have the composition shown in Table B. In a similar manner to the first coating liquid, using constituents shown in Table B, the second layer to the seventh layer were prepared and coated. As a gelatin hardening agent, 1-oxy-3,5-dichloro-s-triazine sodium salt was added to each layer. The spectral sensitizers used for the respective emulsion layers are shown below. The following dyes were used as irradiation preventing dyes in emulsion layers. The structural formulae of compounds including couplers used herein are given below: Seventh Layer : Protective Layer Gelatin 1.33 g/m² Acryl-modified copolymer of polyvinyl alcohol (degree of modification: 17%) 0.17 g/m² Sixth Layer : Ultraviolet Absorbing Layer Gelatin 0.54 g/m² Ultraviolet Absorbent (h) 0.21 g/m² Solvent (j) 0.09 cc/m² Fifth Lyaer : Red-Sensitive Layer Silver chlorobromide emulsion (silver bromide: 0.5 mol%) 0.26 g/m² Gelatin 0.98 g/m² Cyan coupler (k) 0.38 g/m² Dye image stabilizer (ℓ) 0.17 g/m² Solvent (m) 0.23 cc/m² Fourth Layer : Ultraviolet Absorbing Layer Gelatin 1.60 g/m² Ultraviolet absorbent (h) 0.62 g/m² Color mixing preventing agent (i) 0.05 g/m² Solvent (j) 0.26 cc/m² Third Layer : Green-Sensitive Layer Silver chlorobromide emulsion (silver bromide: 0.5 mol%) 0.16 g/m² Gelatin 1.80 g/m² Magenta coupler (e) 0.48 g/m² Dye image stabilizer (f) 0.20 g/m² Solvent (g) 0.68 cc/m² Second Layer : Color Mixing Preventing Layer Gelatin 0.99 g/m² Color mixing preventing agent (d) 0.08 g/m² First Layer : Blue-Sensitive Layer Silver chlorobromide emulsion (silver bromide: 1 mol%) 0.30 g/m² Gelatin 1.86 g/m² Yellow coupler (a) 0.82 g/m² Dye image stabilizer (b) 0.19 g/m² Solvent (c) 0.34 cc/m² Base : Polyethylene-laminated paper (the polyethylene on the first layer side contained a white pigment (TiO₂) and a bluish dye (ultramarine)) The color photographic paper obtained was exposed at 2,854°K through a wedge at 250 CMS and subsequently processed by the following steps, in which the composition of the color developing solution was varied. Processing Step Temperature (°C) Time (s) Color Developing 35 45 Bleach-Fix 35 45 Stabilizing (1) 35 45 Stabilizing (2) 35 20 Stabilizing (3) 35 20 Drying 70-80 60 The stabilizing solutions were used in three-tank countercurrent washing, from stabilizing solution (3) to stabilizing solution (1). The processing solutions used were as follows: Color Developing Solution : Additive C See Table 3 Additive D See Table 3 Benzyl alcohol See Table 3 Diethylene glycol See Table 3 Sodium sulfite 0.2 g Potassium carbonate 30 g Nitrilotriacetic acid 1 g Sodium chloride 1.5 g Color developing agent (see Table 3) 0.01 mol Brightener (4,4′-diaminostilbene) 3.0 g Potassium bromide 0.01 g Water to make 1,000 mℓ pH adjusted using KOH and H₂SO₄ to 10.05 Bleach-Fix Solution : EDTA Fe(III)NH₄·2H₂O 60 g EDTA·2Na·2H₂O 4 g Ammonium thiosulfate (70% aq. soln.) 120 mℓ Sodium sulfite 16 g Glacial acetic acid 7 g Water to make 1,000 mℓ pH adjusted using KOH and H₂SO₄ to 5.5 Stabilizing Solution : Formalin (37% aq. soln.) 0.1 mℓ 1-Hydroxyethylidene-1,1-diphosphonic acid (60% aq. soln.) 1.6 mℓ Bismuth chloride 0.35 g Ammonia water (26% aq. soln.) 2.5 mℓ Nitrilotriacetic acid·3Na 1.0 g EDTA·4H 0.5 g Sodium sulfite 1.0 g 5-Chloro-2-methyl-4-isothiazoline-3-one 50 mg Water to make 1,000 mℓ pH adjusted using KOH and H₂SO₄ to 4.0 A portion of each of the above color developing solutions was placed in an open 1-liter beaker, was allowed to stand at 35°C for 21 days, and then was used in the above processing steps, in an aged solution test. Processing using the color developing solution (fresh solution) that had not been aged is referred to as a fresh solution test. The photographic characteristics obtained by the fresh solution test and the aged test solution are shown in Table 3. The photographic characteristics examined were the Dmin and the gradation in the magenta density. Dmin is the minimum density, and the gradation is the change in density from a density of 0.5 to the density produced by an exposure higher by a factor of 0.3 log E. From Table 3, it can be seen that in Experiments 1 to 4, Dmin and gradation changed with time, and contrast became high, while in Experiments 5 to 18, the change in Dmin and gradation with time was small, demonstrating the remarkable improvement in stability of photographic characteristics. Also, it is seen that in Experiments 5 to 8, the change in Dmin and gradation in Experiment 8 was small, and of the color developing agent, compound d was the best. EXAMPLE 4 Example 3 was repeated except that the spectral sensitizers given below were used in the coating liquids, to prepare a multilayer color photographic paper, and the color developing solutions were allowed to stand at 35°C for 28 days instead of at 35°C for 21 days. The photographic characteristics obtained using the fresh solution and the aged solution in the same manner as in Example 3 are given in Table 4. In the comparative examples (Experiment Nos. 1 to 4), the increase in Dmin and the change in gradation were great, while in the present invention the change in photographic characteristics with time was small, and in particular, good results were obtained when color developing agents c and d were used. When benzyl alcohol was not present, the change in photographic characteristics was small and better results were obtained. EXAMPLE 5 Example 3 was repeated, except that the bromide ion content of the green-sensitive emulsion layer was changed to 80 mol%, to prepare a color photographic paper. The color photographic paper was subjected to wedge exposure, and the changes in photographic characteristics were assessed, based on the occurrence of fogging when using the aged solution. In the case of the developing solution in the comparative examples, fogging increased greatly when the aged solution was used, while in the case of the aged solution of the developing solution according to the invention, the increase in fogging was small and good photographic characteristics were maintained. EXAMPLE 6 Example 4 was repeated, except that the bromide ion content in the green-sensitive emulsion layer was changed to 80 mol%, and the changes in photographic characteristics were assessed using the aged solution in the same way as in Example 4. When the color developing solution according to the invention was used, the increase in fogging was small and good results were obtained. EXAMPLE 7 A color photographic paper was prepared in the same manner as in Example 3, and after it was subjected to wedge exposure, running processing (continuous processing) test were carried out by using color developing solutions in the following steps until the replenishing amount reached 3 times the tank volume (10 liters). Step Temperature (°C) Time (s) Replenishing Amount (mℓ/m²) Color Developer 35 45 160 Bleach-Fix 35 45 100 Rinsing (1) 30 20 Rinsing (2) 30 20 Rinsing (3) 30 20 200 Drying 60-70 30 The rinsing was carried out using a three-tank countercurrent system from rinsing (3) to rinsing (1). The composition of each processing solution used was as follows: Bleach-Fix Solution (the tank solution was the same as the replenisher) EDTA Fe(III)NH₄·2H₂O 60 g EDTA·2Na·2H₂O 4 g Ammonium thiosulfate (70% aq. soln.) 120 mℓ Sodium sulfite 16 g Glacial acetic acid 7 g Water to make 1,000 mℓ pH adjusted using KOH and H₂SO₄ to 5.5 The color photographic paper was processed with the above processing solutions in the above steps, and at the start of the running processing and after the completion of the running processing test, the B.G.R. densities (stain) in unexposed portions were measured using a Fuji automatic densitometer. Further, the sample after the completion of running processing was allowed to stand at 80°C (5 to 10% RH) for 1 month, and the B.G.R. densities in unexposed portions were measured. The results obtained and the changes in photographic characteristics are given in Table 5. From the results given in Table 5, it can be seen that in Experiment Nos. 1 and 2, after the running processing, the stains increased greatly, while in Experiment Nos. 3 to 13, the increase in the stains was quite low. Further, in contrast to Experiment Nos. 1 and 2, with respect to the changes with time after the completion of processing in Experiment Nos. 3 to 13, the increase in the stains was very small. EXAMPLE 8 Using the color photographic paper obtained in Example 4, a running test was performed until the amount of the replenishment of the color developing solution reached 3 times the tank volume (10 l). The composition of the color developing solution was changed as shown in Table 6. The composition of the remaining processing solutions were the same as the compositions of the processing solutions used in Example 7. The changes in photographic characteristics were measured as in Example 7. The results are shown in Table 6. According to the invention, the increase in Dmin in the course of running processing was lowered, and the increase in the Dmin due to the aging of the processed photographic material was lowered. This effect was further improved when benzyl alcohol was omitted. EXAMPLE 9 As shown in Table C, a paper the opposite surfaces of which each had been laminated with a polyethylene layer and which had been subjected to corona treatment was coated with the first layer (lowermost layer) to the seventh layer (uppermost layer) to prepare a photographic paper sample. The preparation of each of the coating liquids for the layers is described below, along with the structures of the couplers, the dye stabilizers, and other compounds used in the coating liquids. The coating liquid for the first layer was prepared as follows. A mixture of 200 g of a yellow coupler, 93.3 g of a fading preventing agent, 10 g of a high boiling point solvent (p), 5 g of a solvent (q) and 600 mℓ of ethyl acetate as a co-solvent was heated to 60°C to be dissolved, and then was mixed with 3,300 mℓ of a 5% aqueous gelatin solution containing 330 mℓ of a 5% aqueous solution of Alkanol B (trade name for an alkylnaphthalenesulfonate produced by Du Pont). The resulting liquid was emulsified using a colloid mill to prepare a coupler dispersion. The ethyl acetate was removed from the dispersion under reduced pressure, then 1,400 g of an emulsion (containing 96.7 g of Ag and 170 g of gelatin) containing a sensitizing dye for a blue-sensitive emulsion and 1-methyl-2-mercapto-5-acetylamino-1,3,4-triazole was added to the dispersion, and 2,600 g of a 10% aqueous gelatin solution was added to prepare a coating liquid. The coating liquids for the second layer to the seventh layer were prepared in the same manner using the composition shown in Table C. The cyan couplers shown in Table 7 were used in the fifth layer to prepare photographic papers.

The couplers used were as follows: The thus-obtained multilayer color photographic papers were subjected to wedge exposure and were processed in the following processing steps. Step Time Temperature (°C) Color Development 3 min 30 s 33 Bleach-Fix 1 min 30 s 33 Rinsing 2 min 30 (3-tank cascade) Drying 1 min 80 The processing solutions used were as follows: Color Development Solution : Water 800 m Sodium sulfite see Table 7 N,N′-Bis(2-hydroxybenzyl)ethylene-diamine-N,N′-diacetic acid 0.1 g Nitrilo-N,N,N-trimethylenephosphonic acid (40% aq. soln.) 1.0 g Potassium bromide 1.0 g Additives C and D See Table 7 Potassium carbonate 30 g N-Ethyl-N-(β-methanesulfonamidoethyl)-3-methyl-4-aminoaniline sulfate 5.5 g Fluorescent brightening agent (4,4′-diaminostilbene) 1.0 g Water to make 1,000 mℓ pH adjusted using KOH to 10.10 Bleach-Fix Solution : Ammonium thiosulfate (70% aq. soln.) 150 mℓ Sodium sulfite 15 g Ethylenediamine iron (III) ammonium salt 60 g Ethylenediaminetetraacetic acid 10 g Fluorescent brightening agent (4,4′-diamionstilbene) 1.0 g 2-Mercapto-5-amino-3,4-thiadiazole 1.0 g Water to make 1,000 mℓ pH adjusted using ammonia water to 7.0 Rinsing Solution : 5-Chloro-2-methyl-4-isothiazoline-3-one 40 mg 2-Methyl-4-isothiazoline-3-one 10 mg 2-Octyl-4-isothiazoline-3-one 10 mg Bismuth chloride (40% aq. soln.) 0.5 g Nitrilo-N,N,N-trimethylenephosphonic acid (40% aq. soln.) 1.0 g 1-Hydroxyethylidene-1,1-diphosphonic acid (60% aq. soln.) 2.5 g Fluorescent brightening agent (4,4′-diaminostilbene) 1.0 g Ammonia water (26% aq. soln.) 2.0 mℓ Water to make 1,000 mℓ pH adjusted using KOH to 7.5 In the above steps, in the same manner as in Example 3, the fresh solution and an aged solution obtained by allowing a part of the color developing solution to stand for 21 days were used, and gradation and Dmin of the cyan image were measured. The increase of Dmin and gradation using the aged solution in comparison with the fresh solution are shown in Table 7. From Table 7, it is seen that in contrast to Experiment Nos. 1 to 3, in Experiment Nos. 4 to 18, even when the developing solution that had been allowed to stand for 21 days was used, the change in Dmin and gradation was small, and therefore that the photographic characteristics were stabilized. It can also be seen, in particular, that when cyan coupler "(C-5)" or "(C-38)" (Experiment Nos. 6, 7, 10, 11, 13, 15, 17 and 18) were used and the sulfite ion concentration in the developing solution was low (Experiment Nos. 10 and 11), the preservability of the developing solution was high and its photographic characteristics were stabilized. EXAMPLE 10 In the same manner as in Example 9, photographic paper samples were prepared except for changing Additive D, and the increase of Dmin and the gradation using the aged solution over those obtained using the fresh solution were measured to determine the change in photographic characteristics. The results are given in Table 8. When using the developer according to the invention, the change in photographic characteristics when using aged solution is small, and in particular, when cyan couplers represented by (C-I) and (C-II) were used, good results were obtained, i.e., the increase in Dmin was low and the change in gradation was small. EXAMPLE 11 Example 1 was repeated, except that in Sample Nos. 9 and 12 (instead of Compounds(Ia)-1 and (Ia)-17), Compounds (Ia)-6, (Ia)-8, (Ia)-11, (Ia)-22, (Ia)-24, (Ia)-28, (Ia)-31, (Ia)-33, (Ia)-34, (Ia)-38 and (Ia)-39 were used. As in Example 1, the compounds according to the present invention provided excellent preservability in comparison with the comparative examples. EXAMPLE 12 Example 10 was repeated, except that Compounds II-(3), II-(6), II-(7), II-(12), II-(16), II-(19) and II-(23) were used. Good results were obtained in the increase in Dmin and the change in gradation. EXAMPLE 13 A color photographic paper prepared in the same manner as in Example 4, except that the following spectral sensitizers for blue-sensitive, green-sensitive and red-sensitive emulsion layers were used. The papers were imagewise exposed, and subjected to a running processing (continuous processing) test in the same processing steps as those in Example 8, using the same color deveooping solutions as in Example 8 until the amount of the replenisher became 3 times the tank volume. Spectral sensitizers used: As the rinsing liquid, the following washing water was used. Washing Water Tap water was passed through a mixed bed chromatographic column loaded with an H-type strong acid cation exchange resin (Diaion SK-IB manufactured by Mitsubishi Chemical Industries Ltd.) and an OH-type strong basic anion exchange resin (Diaion SA-10A manufactured by Mitsubishi Chemical Industries Ltd.) to obtain water having a calcium ion content of 1.1 mg/ℓ, a magnesium ion content of 0.5 mg/ℓ and a pH of 6.9. As a fungicide, sodium dichloroisocyanurate (20 mg/ℓ) was added thereto. After continuous processing, the same assessment as in Example 8 was carried out, and the same results as in Example 8 were obtained. These results demonstrate that according to the present invention, the stability and the color forming property of a color developing solution were improved, and that when an aged color developing solution was used, the increase in fogging and change in gradation were greatly reduced, to provide color images with excellent photographic characteristics. This effect in the present invention was remarkable, particularly in a color developing solution substantially free from benzyl alcohol that is a harmful environmental pollutant. Further, when a photographic material containing specific cyan couplers was processed, the effect of the present invention was remarkably improved. Additionally in continuous processing, the increase in fogging was remarkably reduced and the color images obtained were excellent in stability despite the use of aged developer.
