Abstract: There are disclosed a composition for color-development and a method for processing a silver halide color photographic material using same wherein the composition comprises an aromatic primary amine color developing agent, a compound represented formula (I) or a (II), and a polymer, being free from sulfite ion. The disclosure described a method for processing a silver halide color photographic material that gives a color photographic image high in maximum density and good in whiteness without causing problems by tarry substance in a color developer.

Description: The present invention relates to a method for processing silver halide color photographic materials. More particularly the present invention relates to a color processing method that prevents stain due to oxidation products of color developing agents and gives a photographic image excellent in whiteness. It is known that color developers containing an aromatic primary amine developing agent autoxidize when they come in contact with air (T.H. James, The Theory of the Photographic Process, 4th edition, p. 315 (1979)). As a result the color developer turns dark brown, and further a black tarry contaminant is produced. This black tarry contaminant will stick to the photographic material and become stain after the processing, or it will stick to processor parts in contact with the color developer, such as the processing solution tank, pipelines, and conveying rollers, and will stain heavily the processor when continuous processing is carried out in an automatic processor by supplying the developer. In particular, when parts that come in contact with the photographic material are stained, the stain will be transferred to the photographic material and the commercial value of the photographic material will be lost. Recently, it has become practiced that color photographic material is subjected to color processing in a short period of time, up to 5 min, under high temperature conditions of 30°C or higher. This high-temperature color developer is apt to be oxidized by air and is liable to produce the above tarry contaminant. Further, in the field of development processing of color negative film and color paper, development processing using small-sized automatic processors called "mini-labs" is becoming prevalent very quickly. In the "mini-lab" processing, since the processing amount per day is small, the time of the color developer staying in the color developer tank becomes longer and the color developer is in such a state that it is liable to be oxidized by air. As means of preventing air oxidation of color developers, techniques wherein a compound called a preservative is added to the color developer have been practiced. As preservatives, conventionally compounds such as sulfites and hydroxylamine salts are known (L.F.A. Mason, Photographic Processing Chemistry , p. 34 (1966)). EP-A-273986 discloses a developer composition comprising a hydroxylamine derivative to inhibit tar generation and JP-A-58-120250 discloses a developer solution comprising polyvinylpyrrolidone, whereby the effective components of the developer solution are not decomposed. In particular, sulfites are remarkably effective in preventing of coloring of the color developer and the occurrence of a tarry contaminant. However, it is known that, for the high-silver-chloride color photographic materials used recently in quick development processing, it is practically difficult to use sulfites that highly block color formation and highly solubilize silver. To perform quick development processing and low-replenishment processing wherein a high-silver-chloride photographic material is used, many preservatives in place of sulfites and hydroxylamine salts have been studied. For example, International Publication Patent No. WO 87-04534 discloses a method wherein alkylsubstituted hydroxylamines are used, and JP-A ("JP-A" means unexamined published Japanese patent application) Nos. 170642/1988 and 146041/1988 disclose a method wherein hydrazines and hydrazides are used as preservatives. It is also known that many compounds known as chelating agents of metal ions have been shown to play an important role in the preservation of developers (Research Disclosure No. 17048, June 1978), and they can be used together with the above preservatives. Although all of the above compounds have a high effect for suppressing air oxidation of color developers and for keeping photographic performance, they cannot suppress air oxidation completely, which results in the formation of a tarry contaminant that causes various injurious problems. In particular, in low-replenishment processing, since the periods of a color developer and a color developer replenisher staying in the tanks are longer and the pH and the concentration of the developing agent of the color developer replenisher are high, they are in a state liable to be oxidized by air, and therefore development of techniques is desired wherein formation of the above tarry contaminant in color developing agents is prevented or the influence of the contaminant is made unharmful. The first object of the present invention is to provide a method for processing a silver halide color photographic material that gives a color photographic image high in maximum density and good in whiteness. The second object of the present invention is to provide a composition for color-development that can prevent a color developer from forming a tarry contaminant or that can make the influence of a contaminant of a color developer harmless, that can prevent a tarry contaminant from sticking to parts of a processing machine or an automatic processor (e.g., a processing tank, pipelines, and conveying rollers), which stains them; and that can obtain a color photographic image excellent in brightness by improving desilvering property. The objects of the present invention have been attained by (1) A composition for color-development which comprises at least one aromatic primary amine color developing agent and at least one of compounds represented by the below-mentioned formula (I) or (II), and contains sulfite ions in an amount of 5.0 x 10 -3 mol/l or less wherein R 1 and R 2 each represent a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, or a heteroaromatic group, and R 1 and R 2 are not hydrogen atoms at the same time and they may bond each other together with the nitrogen atom to form a heterocyclic ring, wherein R 1 and R 2 may be further substituted; wherein R 31 , R 32 , and R 33 each represent a hydrogen atom, an alkyl group, an aryl group, or a heterocyclic group, R 34 represents a hydroxyl group, a hydroxyamine group, an alkyl group, an aryl group, a heterocyclic group, an alkoxy group, an aryloxy group, a carbamoyl group, or an amino group, and X 31 represents a bivalent group selected from -CO-, -SO 2 -, or and n is 0 or 1, wherein R 31 to R 32 each may have a substituent and when n is 0, R 34 represents a group selected from an alkyl group, an aryl group and a heterocyclic group and R 33 and R 34 may form cooperatively a heterocyclic ring, characterised in that the composition comprises at least one polymer selected from the group consisting of a vinyl alcohol homopolymer and a vinyl alcohol copolymer; and (2) A method for processing a silver halide color photographic material, characterised in that a silver halide color photographic material that has been exposed to light imagewise is processed with the color developing composition as disclosed above.

In formula (II), R 31 to R 34 each may have a substituent. As the heterocyclic ring represented by R 31 to R 33 , a 5- to 6-membered one is preferable, which is made up of those selected from C, H, O, N, S and halogen atoms, and it may be saturated or unsaturated. When n = 0, R 34 represents a group selected from an alkyl group, an aryl group, and a heterocyclic group, and R 33 and R 34 may form cooperatively a heterocyclic ring.

The polymerization degree of said polymer used in the present invention is preferably 100 to 5,000 more preferably 200 to 2,000. Although there is no particular limit to the molecular weight of said polymer used in the present invention, preferable polymers are those having a molecular weight on the order of 1,000 to 50,000. When vinyl alcohol is used in the form of a copolymer, as compounds to be copolymerized therewith, for example, acryl esters, acrylamide, ethylene-imine, vinylpyridine, styrene, vinylmethylimidazole, acrylic acid, methacrylic acid, maleic anhydride, maleic acid, styrenesulfonic acid, vinylbenzoic acid, phenol, polyesters, silicon, vinylsuccinimide, acrylonitrile, vinyl esters, arylates, and vinylpyrrolidone can be mentioned, but the present invention is not limited to them if the copolymer contains 20 mol% or more of vinyl alcohol. Preferable copolymers are those containing vinyl alcohol in an amount of 40 mol% or more, more preferably in particular of 70 mol% or more and desirably these copolymers are substantially soluble in water. In the present invention, a copolymer or a homopolymer of these compounds is preferable. Preferable specific examples of said polymer are given below III-1 polyvinyl alcohol III-2 polyvinyl alcohol/vinyl acetate copolymer III-3 vinyl alcohol/acrylic acid copolymer III-4 vinyl alcohol/vinylpyrrolidone copolymer III-5 vinyl alcohol/methacrylic acid copolymer III-6 vinyl alcohol/maleic acid copolymer III-7 vinyl alcohol/acrylonitrile copolymer III-8 vinyl alcohol/acrylate copolymer III-9 vinyl alcohol/acrylate/acrylic acid copolymer Preferably the amount of the above compound to be added to the color developer is 0.05 g/ℓ to 2 g/ℓ, and more preferably 0.1 g/ℓ to 1 g/ℓ. In the present invention the color developer contains sulfite ions in an amount of 5.0 x 10 -3 mol/ℓ or less, i.e. it is "substantially free from sulfite ions". Particularly preferably the color developer does not contain sulfite ions at all in the case wherein a high-silver-chloride color photographic material having a silver chloride content of 80 mol% or more is subjected to color processing in view of color formation and process stability. In the present invention, however, a very small amount of sulfite ions used for the prevention of oxidation of the processing agent kit in which a developing agent is condensed before it is adjusted to be a tank solution is excluded from consideration. The above polymer is also used for parts of neutral pH and parts of acid pH of the processing agent kit. Herein, the polymer is desirably at a pH at which it can dissolve even if it is in a high concentration. The inventors have investigated in various ways for the purpose of preventing a color developer from turning colored and forming a black tarry contaminant and for the purpose of making the coloration and the contaminant unharmful, and as a result we have attained the purposes by using a compound of formula (I) or (II) in combination with a homopolymer or a copolymer of vinyl alcohol even in the absence of sulfite ions, and we have found a quick and low-replenishment processing method for processing a high-silver-chloride color photographic material in which the maximum density is high, the white background is excellent, and a contaminant is not formed. Although the compounds represented by formulae (I) and (II) are described as preservatives for developing agents in International Publication Patent No. WO 87-04534 and JP-A Nos. 146041/1988 and 170642/1986, their effect for preventing the above color developer from turning colored and forming a tarry contaminant was inadequate. If the above polymer of the present invention was used alone, the effect for preventing the above color developer from turning colored and forming a tarry contaminant was not exhibited at all, and when the above polymer of the present invention was used in combination with a preservative other than those of the present invention, such an effect could not been obtained. The effect obtained by the above combination is very unique, having not been expected at all, and is very surprising. JP-B ("JP-B" means examined Japanese patent publication) No. 20743/1972 describes the addition of the polymer of the present invention to a color developer. However, that addition is intended to prevent the color developer from depositing crystals, the process of the publication is carried out in the absence of compounds of formulae (I) and (II) and in the presence of sulfite ions, and the publication describes, for example, neither problems involved in the use of high-silver-chloride photographic materials nor measures of solving such problems as are taken up in the present invention. The color developer used in the present invention will now be described. In the present invention, the combination of a compound of formula (I) and (II) with another preservative is preferable in that the processing solution is stabilized and the processing stability in continuous processing is improved. As preferable preservatives can be mentioned hydroxamic acids, phenols, α-hydroxyketones, α-aminoketones, saccharides, monoamines, diamines, polyamines, quaternary ammonium salts, nitroxy radicals, alcohols, oximes, diamide compounds, and condensed ring-type amines. They are disclosed, for example, in JP-A Nos. 147823/1986, 173595/1986, 165621/1986, 186559/1986, 170756/1986, 188742/1986, and 188741/1986, U.S. Patent Nos. 3,615,503 and 2,494,903, JP-A No. 143020/1987, and JP-B No. 30496/1973. Among these, compounds represented by formula (IV) are preferable to use in combination with a compound represented by formula (I) or (II). wherein R 71 , R 72 , and R 73 , each represent a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, an aralkyl group or a heterocyclic group, and R 71 and R 72 , R 71 and R 73 , or R 72 and R 73 may bond together to form a nitrogen-containing heterocyclic group. R 71 , R 72 , and R 73 may have substituent. Particularly preferably R 71 , R 72 , and R 73 each represent a hydrogen atom or an alkyl group. As a substituent can be mentioned, for example, a hydroxyl group, a sulfo group, a carboxyl group, a halogen atom, a nitro group, and an amino group.

As typical organic antifoggants can be mentioned, for example, nitrogen-containing heterocyclic compounds, such as benzotriazole, 6-nitrobenzimidazole, 5-nitroisoindazole, 5-methylbenzotriazole, 5-nitrobenzotriazole, 5-chloro-benzotriazole, 2-thiazolyl-benzimidazole, 2-thiazolylmethyl-benzimidazole, indazole, hydroxyazaindolizine, and adenine. For the purpose of preventing fogging or the like, particularly in the processing a high-silver-chloride photographic material containing 80 mol% or over of silver chloride, it is preferable that chloride ions and bromide ions exist in the color developer in an amount of 3.0 x 10 -2 to 1.5 x 10 -1 mol/ℓ and 3.5 x 10 -5 to 1 x 10 -3 mol/ℓ. respectively. It is preferable that the color developer used in the present invention contains a brightening agent. As the brightening agent, 4,4'-diamino-2,2'-disulfostilbene compounds are preferable, which will be added in an amount of 0 to 10 g/ℓ, preferably 0.1 to 6 g/ℓ. If required, various surface-active agents, such as alkylsulfonic acids, arylphosphonic acids, aliphatic carboxylic acids, and aromatic carboxylic acids may be added. The processing time with the color developer for use in the present invention may be, for example, 10 to 120 see., preferably 20 to 60 see., in which effects of the present invention being remarkable. The processing temperature is 33 to 45°C, and preferably 36 to 40°C, under such conditions the effect of the present invention is particularly remarkable. The amount of the replenisher of the color developer during continuous processing is 20 to 220 mℓ, preferably 25 to 160 mℓ, and particularly preferably 30 to 110 mℓ, per 1 m 2 of the photographic material, which is preferable because the effect of the present invention can be exhibited efficiently. The color developer of the present invention has relatively better performance than that obtained by combinations other than the combination of the present invention, even if the opened surface ratio of the color developer (the air contact surface area (cm 2 )/the solution volume (cm 3 )) is in any state. Preferably the opened surface ratio is 0 to 0.1 cm -1 in view of the stability of the color developer. In the continuous processing, preferably, in practice, the opened surface ratio is in the range of 0.001 to 0.05 cm -1 , more preferably 0.002 to 0.03 cm -1 . Generally when hydroxylamine or the like is used as a preservative, it is widely known that even if the liquid opening rate of the color developer is made small, decomposition of the color developer due to heat or trace metals takes place. However, in the present color developer, such decomposition is very little, and the color developer can be stored for a long period of time or can practically be well used continuously for a long period of time without difficulty. Therefore, in such a case, preferably the opened surface ratio is smaller, and most preferably the opened surface ratio is 0 to 0.002 cm -1 . Conversely, there is a method wherein a large opened surface ratio is used, provided that after a certain amount of a photographic material is processed, the processing solution is discarded, and even in such a processing method, the constitution according to the present invention can exhibit excellent performance. In the present invention desilvering is effected after dolor development. Alternatively, after color development water-washing may be effected, and then desilvering may be effected. Further, when fixing is effected after bleaching, water-washing may be effected between the bleaching step and the fixing step, if necessary. In particular, preferably the above-mentioned water-washing may be carried out, in the case of regeneration treatment of fixing solution. Although the desilvering step generally consists of a bleaching step and a fixing step, particularly preferably the both steps are carried out simultaneously. In the bleaching solution or bleach-fixing solution used in the present invention, an aminopolycarboxylic acid-iron complex is used as a bleaching agent. Aminopolycarboxylic acids to be useful preferably are shown below A-1 Methyliminodiacetic acid A-2 Iminodiacetic acid A-3 Ethylenediaminetetraacetic acid A-4 Diethylentriamineheptaacetic acid A-5 Glycoletherdiaminetetraacetic acid A-6 Cyclohexanediaminetetraacetic acid A-7 1,3-Propanediaminetetraacetic acid A-8 1,4-Butanediaminetetraacetic acid A-9 Hydroxyethylethylenediaminetriacetic acid These bleaching agents can be used in combination with each other, if necessary. The amount of bleaching agent to be used is preferably to be small for preventing environmental pollution,and is preferably 0.01 to 0.2 mol, more preferably 0.02 to 0.1 mol, per liter of bleaching solution or bleach-fixing solution. Although the above-mentioned bleaching agents are generally used in the form of iron (III) complex in the present invention, particularly preferably iron (II) complex is contained in a ratio of 3 to 35 % of total iron complex, in view of the improvement of whiteness. When the ratio of iron (II) complex is in the above range, stain (tarr adhered and color remaining ratio) originated from color development is further reduced. More preferably, iron (II) complex consists of 10 to 30 % of total iron complex. To get the composition having the above ratio iron (III) complex and iron (II) complex may be mixed as the above ratio, or only iron (III) complex may be added, followed by partially reduction to iron (II) complex. As reduction process can be mentioned a method of adding such reducing reagent as sulfite and ascorbic acid, a method to control iron (II) formed by bleaching using aeration, and a method to keep iron (II) complex concentration at a somewhat higher level by reusing overflowed solution after processing (regeneration use). Among these, method to control iron (II) concentration by aeration or regeneration is most preferable embodiment because of being easy and cheap method. In the regeneration, bleaching solutions from other processing process can be regenerated when combined together. Further, the bleaching solution or the bleach-fixing solution used in the present invention can contain rehalogenation agents, such as bromides (e.g., potassium bromide, sodium bromide, and ammonium bromide), chlorides (e.g., potassium chloride, sodium chloride, and ammonium chloride), or iodides (e.g., ammonium iodide). In the bleaching solution or the bleach-fixing solution relating to the present invention, various compounds may be used as a bleach accelerating agent. Examples of useful bleach accelerating agent are described in the following specification of patent: compounds having a mercapto group or a disulfide bond described in U.S. Patent No. 3,893,858, German Patent No. 1,290,812, and JP-A No. 95630/1978, thiazoline derivatives described in JP-A No. 140129/1975, thiourea compounds described in U.S. Patent No. 3,706,561, polyoxiethylene compounds described in German Patent No. 2,748,430, and polyamine compounds described in JP-B No. 8836/1970. The fixing agent used in the bleach-fixing solution or the fixing solution relating to the present invention includes known fixing agents, for example, thiosulfates such as sodium thiosulfate and ammonium thiosulfate, thiocyanates, such as sodium thiocyanate and ammonium thiocyanate, thioether compounds such as ethylenebisthioglycolic acid and 3,6-dithia-1,8-octanediol, and water-soluble silver halide solvents such as thiourea, and use can be made one or mixture of two or more of them. Further, a special bleach-fixing solution comprising a combination of a fixing agent and a large amount of silver halide such as silver iodide, as described in JP-A No. 155354/1980, can be used. In the present invention, preferably thiosulfates and particularly ammonium thiosulfate can be used. The amount of the fixing agent per liter is preferably 0.3 to 2 mol, more preferably in the range of 0.5 to 1.0 mol. The bleach-fixing solution or the fixing solution used in the present invention contains, as a preservative, compounds that release sulfite ion, such as sulfites (e.g., sodium sulfite, potassium sulfite, and ammonium sulfite), bisulfites (e.g., ammonium bisulfite, sodium bisulfite, and potassium bisulfite), and methabisulfites (e.g., potassium methabisulfite, sodium methabisulfite, and ammonium methabisulfite). Preferably these compounds are contained in an amount of about, 0.02 to 0.60 mol per liter, and more preferably 0.04 to 0.40 mol per liter, in terms of sulfite ions. In particular, the addition of ammonium sulfite is preferable. As a preservative, generally a sulfite is added, but other compounds, such as ascorbic acid, carbonyl bisulfite addition compound, sulfinic acids, or carbonyl compounds, may be added. In the present invention, preferably the pH of the bleach-fixing solution or the fixing solution is in a range of 4 to 6.5, and more preferably 5 to 6, in view of the improvement of whiteness. It is considered that, when pH is kept in the above-mentioned range, the whiteness is improved by easily removing of stain (tarr adhered and remaining color) originated from the processing. To adjust pH, according to necessary, hydrochloric acid, sulfuric acid, nitric acid, acetic acid, bicarbonate, ammonia, caustic potassium, caustic sodium, sodium carbonate, and potassium carbonate can be added. In the present invention, the processing time by fixing solution or bleach-fixing solution may be 10 to 120 see and preferably 20 to 60 see. And the replenishing amount may be 20 to 250 me, preferably 30 to 250 mℓ, per m 2 of photographic material. Preferably, the pH of bleaching solution may be 0.1 to 7, particularly preferably 1.0 to 6.0. The time in bleaching bath may be 10 see. to 2 min, preferably 30 sec. to 100 sec., and the processing temperature may be 25°C to 40°C. The replenishing amount may be 30 to 500 mℓ, preferably 50 to 300 mℓ, per m 2 of photographic material. Additionally, the bleach-fixing solution, the bleaching solution,or the fixing solution may contain various fluorescent brightening agents, antifoaming agents, surface-active agents, or organic solvents such as polyvinylpyrrolidone. If required, one or more of inorganic or organicacids or alkaline metal or ammonium salts thereof that has a pH-buffering property, such as, boric acid, borax, sodium methaborate, acetic acid, sodium acetate, potassium carbonate, phosphorous acid, phosphoric acid, sodium phosphate, citric acid, sodium citrate, and tartaric acid, or corrosion preventing agents such as ammonium nitrate or guanidine can be contained. Further, chelating agents or anti-mold agents may be added, according to needs. In the present invention, the bleach-fixing solution, the bleaching solution, or the fixing solution can be reused after regeneration. Reuse is preferable in view of reducing the volume of waste solution. In the present invention, method for regeneration and reuse of bleach-fixing solution or bleaching solution is preferably to reuse solution which has been additionally added insufficient chemicals (e.g., generally, bleaching agent, halide compound and acid) to the overflowed solution generated in the processing and stored until a prescribed volume, as replenisher, but it is not limited to this method. Tank solution or stocked solution may be subjected to aeration. The reuse of fixing solution after desilvering may be a most preferable embodiment in the present invention. although the method for desilvering method is selected from a method using steel-wool described in JP-A No. 3624/1973 and U.S. Patent No. 4,065,313, an electrolysis-method described in U.S. Patent Nos. 4,014,764 and 4,036,715, JP-B No. 40491/1978, and JP-A No. 23245/1986, and a dilution-method described in JP-B No. 33697/1981, the electrolysis-method is particularly preferable to use. Desilvering can be effected to tank solution by providing the apparatus, or stocked solution of overflow. Although the generation method of fixing solution may be preferable to reuse solution which has been added insufficient chemicals (e.g., generally, fixing agent, preservative, and pH-adjusting agent) to the overflowed solution after desilvering as replenisher, but the invention is not limited to this. Further, a method for desilvering and regeneration of solution combined with other used fixing solution may be a preferable embodiment in view of shortening time and number of regeneration. The silver halide color photographic material used in the present invention is generally washed and/or stabilized after the fixing or the desilvering, such as the bleach-fixing. The amount of washing water in the washing step can be set over a wide range, depending on the characteristics of the photographic material (e.g., the characteristics of the materials used, such as couplers), the application of the photographic material, the washing water temperature, the number of the washing water tanks (stages), the type of replenishing (i.e., depending on whether the replenishing is of the countercurrent type or of the down flow type), and other various conditions. The relationship between the number of washing water tanks and the amount of water in the multi-stage countercurrent system can be determined based on the method described in Journal of the Society of Motion Picture and Television Engineers, Vol. 64, pp. 248 to 253 (May 1955). According to the multi-stage countercurrent system, the amount of washing water can be reduced considerably. But a problem arises that bacteria can propagate due to the increase in the residence time of the water in the tanks, and the suspended matter produced will adhere to the photographic material. To solve such a problem in processing the color photographic material of the present invention, the process for reducing calcium and magnesium described in JP-A No. 288838/1987 can be used quite effectively. Further, isothiazolone compounds and thiabendazoles described in JP-A No. 8542/1982, chlorine-type bactericides, such as sodium chlorinated isocyanurates described in JP-A No. 120145/1986, benzotriazoles described in JP-A No. 267761/1986, copper ions, and bactericides described by Hiroshi Horiguchi in Bokin Bobai-zai no Kagaku, Biseibutsu no Genkin, Sakkin, Bobai Gijutsu (edited by Eiseigijutsu-kai), and Bokin Bobai-zai Jiten (edited by Nihon Bokin Bobai-gakkai), can be used. The pH range of the washing water in the processing steps for the photographic material of the present invention may be 4 to 9, preferably 5 to 8. The temperature and time of washing, which can be set according to the use or property of the photographic material, is generally in the range 15 to 45°C and 20 sec. to 2 min., preferably 25 to 40°C and 30 sec. to 1 min. According to the present invention good photographic properties without the increasing of stain can be obtained even if processing by such short-time washing. Further, the photographic materials of the present invention can be processed directly by a stabilizing solution without a washing step. In such a stabilizing process, all known methods described, for example, in JP-A Nos. 8543/1982, 14834/1983, 184343/1984, 220345/1985, 238832/1985, 239784/1985, 239749/1985, 4045/1986, and 118749/1986 can be used. A preferred inclusion is to use a stabilizing bath containing 1-hydroxyethylidene-1,1-diphosphonate, 5-chloro-2-methyl-4-isothiazolone-3-one, a bismuth compound, or an ammonium compound. In some cases a stabilizing process is carried out following the above-described washing process, and an example of such cases is a stabilizing bath containing formalin and a surface-active agent for use as a final bath for color photographic materials for photographing. The time of the processing steps of the present invention is defined as the period from the time when the photographic material is brought in contact with the color developer to the time when the phptographic material leaves the final bath (which is generally a washing bath or a stabilizing bath), and the effect of the present invention can be exhibited remarkably in rapid processing steps wherein the time of those processing steps is 3 min 30 see or below, preferably 3 min or below. Now the color photographic material to be used in the present invention will be described in detail. The color photographic material used in the present invention can be constituted by applying at least each of a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer on a base. For common color print papers, the above silver halide emulsion layers are applied in the above-stated order on the base, but the order may be changed. Color reproduction by the subtractive color process can be performed by incorporating, into these photosensitive emulsion layers, silver halide emulsions sensitive to respective wavelength ranges, and so-called color couplers capable of forming dyes complementary to light to which the couplers are respectively sensitive, that is, capable of forming yellow complementary to blue, magenta complementary to green, and cyan complementary to red. However, the constitution may be such that the photosensitive layers and the color formed from the couplers do not have the above relationship. The silver halide emulsion to be used in the present invention is more preferably, in a rapid and low amount replenishing processing, one having a composition of 80 mol% or more of silver chloride and being substantially free from silver iodide. Herein the term "substantially free from silver iodide" means that the silver iodide content in 1 mol% or below, and preferably 0.2 mol% or below. When the silver chloride content in lower or the silver iodide content is higher than the above-mentioned, rapid processing in impossible because of the developing speed being slow. Therefore, a higher silver chloride content is preferable. That is, 90 mol% or more is preferably, and 95 mol% or more is more preferably. Further, a silver halide emulsion that has silver chloride content still increased is preferably employed for reducing the replenishing amount. In such a case, 98 to 99.9 mol% of silver chloride content such as almost pure silver chloride is also preferably used. However, when a pure silver chloride is used, in some cases there may be caused disadvantages with respect to sensitivity and prevention of pressure marks. Although the halogen compositions of the emulsions may be the same or different from grain to grain, if emulsions whose grains have the same halogen composition are used, it is easy to make the properties of the grains homogeneous. With respect to the halogen composition distribution in a silver halide emulsion grain, for example, a grain having a so-called uniform-type structure, wherein the composition is uniform throughout the silver halide grain, a grain having a so-called layered-type structure, wherein the halogen composition of the core of the silver halide grain is different from that of the shell (which may comprises a single layer or layers) surrounding the core, or a grain having a structure with nonlayered parts different in halogen composition in the grain or on the surface of the grain (if the nonlayered parts are present on the surface of the grain, the structure has parts different in halogen composition joined onto the edges, the corners, or the planes of the grain) may be suitably selected and used. To secure high sensitivity, it is more advantageous to use either of the latter two than to use grains having a uniform-type structure, which is also preferable in view of the pressure resistance. If the silver halide grains have the above-mentioned structure, the boundary section between parts different in halogen composition may be a clear boundary, or an unclear boundary due to the formation of mixed crystals caused by the difference in composition, or it may have positively varied continuous structures. In these high-silver-chloride emulsions, the structure is preferably such that the silver bromide localized phase in the layered form or nonlayered form is present in the silver halide grain and/or on the surface of the silver halide grain as mentioned above. The silver bromide content of the composition of the above-mentioned localized phase is preferably at least 10 mol%, and more preferably over 20 mol%. The localized phase may be present in the grain, or on the edges, or corners of the grain surfaces, or on the planes of the grains, and a preferable example is a localized layer epitaxially grown on each corner of the grain. On the other hand, for the purpose of suppressing the lowering of the sensitivity as much as possible when the photographic material undergoes pressure, even in the case of high-silver-chloride emulsions having a silver chloride content of 90 mol% or over, it is preferably also practiced to use grains having a uniform-type structure, wherein the distribution of the halogen composition in the grain is small. In the present invention, the coating amount of silver halide is preferably 0.75 g/m 2 or less in terms of silver in view of processing-rapidness and processing-stability. A coating amount of 0.70 ∼ 0.40 g/m 2 is more preferable and 0.65 ∼ 0.45 g/m 2 is most preferable. The average grain size of the silver halide grains contained in the silver halide emulsion used in the present invention (the diameter of a circle equivalent to the projected area of the grain is assumed to be the grain size, and the number average of grain sizes is assumed to be an average grain size) is preferably 0.1 to 2 µm. Further, the grain size distribution thereof is preferably one that is a so-called monodisperse dispersion, having a deviation coefficient (obtained by dividing the standard deviation of the grain size by the average grain size) of 20 % or below, and desirably 15 % or below. In this case, for the purpose of obtaining one having a wide latitude, it is also preferable that monodisperse emulsions as mentioned above are blended to be used in the same layer, or are applied in layers. As to the shape of the silver halide grains contained in the photographic emulsion, use can be made of grain in a regular crystal form, such as cubic, tetradecahedral, or octahedral, or grains in an irregular crystal form, such as spherical or planar, or grains that are a composite of these. Also, a mixture of silver halide grains having various crystal forms can be used. In the present invention, of these, grains containing grains in a regular crystal form in an amount of 50 % or over, preferably 70 % or over, and more preferably 90 % or over, are preferred. Further, besides those mentioned above, an emulsion wherein the tabular grains having an average aspect ratio (the diameter of a circle calculated/the thickness) of 5 or over, and preferably 8 or over, exceed 50 % of the total of the grains in terms of the projected area, can be preferably used. The silver chloromide emulsion used in the present invention can be prepared by methods described, for example, by P. Glafkides, in Chimie et Phisique Photographique (published by Paul Montel, 1967), by G.F. Duffin in Photographic Emulsion Chemistry (published by Focal Press, 1966), and by V.L. Zelikman et al. in Making and Coating Photographic Emulsion (published by Focal Press, 1964). That is, any of the acid process, the neutral process, the ammonia process, etc. can be used, and to react a soluble silver salt and a soluble halide, for example, any of the single-jet process, the double-jet process, or a combination of these can be used. A process of forming grains in an atmosphere having excess silver ions (the so-called reverse precipitation process) can also be used. A process wherein the pAg in the liquid phase where a silver halide is to be formed is kept constant, that is, the so-called controlled double-jet process, can be used as one type of double-jet process. According to the controlled double-jet process, a silver halide emulsion wherein the crystal form is regular and the grain sizes are nearly uniform can be obtained. Into the silver halide emulsion used in the present invention, various polyvalent metal ion impurities can be introduced during the formation or physical ripening of the emulsion grains. Examples of such compounds to be used include salts of cadmium, zinc, lead, copper, and thallium, and salts or complex salts of an element of Group VIII, such as iron, ruthenium, rhodium, palladium, osmium, iridium, and platinum. Particularly the elements of Group VIII can be preferably used. Although the amount of these compounds to be added varies over a wide range according to the purpose, preferably the amount is 10 -9 to 10 -2 mol for the silver halide. The silver halide emulsion used in the present invention is generally chemically sensitized and spectrally sensitized. As the chemical sensitization method, sulfur sensitization, wherein typically an unstable sulfur compound is added, noble metal sensitization, represented by gold sensitization, or reduction sensitization can be used alone or in combination. As the compounds used in the chemical sensitization, preferably those described in JP-A No. 215272/1987, page 18 (the right lower column) to page 22 (the right upper column), are used. The spectral sensitization is carried out for the purpose of providing the emulsions of the layers of the photographic material of the present invention with spectral sensitivities in desired wavelength regions. In the present invention, the spectral sensitization is preferably carried out by adding dyes that absorb light in the wavelength ranges corresponding to the desired spectral sensitivities, that is, by adding spectrally sensitizing dyes. As the spectrally sensitizing dyes used herein, for example, those described by F.M. Harmer in "Heterocyclic compounds - Cyanine dyes and related compounds" (published by John Wiley & Sons [New York, London], 1964) can be mentioned. As specific examples of the compounds and the spectral sensitization method, those described in the above JP-A No. 215272/1987, page 22 (the right upper column) to page 38, are preferably used. In the silver halide emulsion used in the present invention, various compounds or their precursors can be added for the purpose of stabilizing the photographic performance or preventing fogging that will take place during the process of the production of the photographic material, or during the storage or photographic processing of the photographic material. As specific examples of these compounds, those described in the above-mentioned JP-A No. 215272/1987, pages 39 to 72, are preferably used. As the emulsion used in the present invention, use is made of a so-called surface-sensitive emulsion, wherein a latent image is formed mainly on the grain surface, or of a so-called internal-image emulsion, wherein a latent image is formed mainly within the grains.

The couplers represented by formulae (C-I) to (Y) are contained in the silver halide emulsion layer constituting the photographic layer generally in an amount of 0.1 to 1.0 mol, preferably 0.1 to 0.5 mol, per mol of the silver halide. In the present invention, in order to add the coupler to the photographic layer, various known techniques can be applied. Generally, the oil-in-water dispersion method known, as the oil-protect method, can be used for the addition, that is, after the coupler is dissolved in a solvent, it is emulsified and dispersed into an aqueous gelatin solution containing a surface-active agent. Alternatively, it is also possible that the coupler solution containing a surface-active agent can be added to water or an aqueous gelatin solution to form an oil-in-water dispersion with phase reversal of the emulsion. In the case of an alkali-soluble coupler, it can be dispersed by the so-called Fisher dispersion method. It is also possible that the low-boiling organic solvent can be removed from the coupler dispersion by means of distillation, noodle washing, ultrafiltration, or the like, followed by mixing with the photographic emulsion. As the dispersion medium for the couplers, it is preferable to use a high-boiling organic solvent and/or a water-insoluble polymer compound having a dielectric constant of 2 to 20 (25°C) and a refractive index of 1.5 to 1.7 (25°C). As the high-boiling organic solvent for the coupler of the present invention and other couplers, a high-boiling organic solvent represented by the following formula (A), (B), (C), (D), or (E) is preferably used. wherein W 1 , W 2 , and W 3 each represent a substituted or unsubstituted alkyl group, cycloalkyl group, alkenyl group, aryl group or heterocyclic group, W 4 represents W 1 , OW 1 or S-W 1 , n is an integer of 1 to 5, when n is 2 or over, W 4 groups may be the same or different, and in formula (E), W 1 and W 2 may together form a condensed ring. Among these, compounds represented by formulae (A), (B), and (C) are preferable for the purpose of the present invention. Now, compounds represented by formulae (A) to (C) are described in more details. In formula (A), (B), or (C), when W 1 W 2 , or W 3 has a further substituent, the substituent may be one having a connecting group selected from one or more of -CON , -RN (wherein R represents a phenyl group having 2- to 6- valency that is removed hydrogen atom), and -O-. Alkyl group represented by W 1 , W 2 , or W 3 in formulae (A), (B), and (C) may be either straight chain-type or branched type, for example, methyl group, ethyl group, propyl group, butyl group, pentyl group, hexyl group, heptyl group, octyl group, nonyl group, decyl group, undecyl group, dodecyl group, tridecyl group, tetradecyl group, pentadecyl group, hexadecyl group, heptadecyl group, octadecyl group, nonadecyl group, or eicodecyl group. As substituents allowable for these alkyl groups, can be mentioned, taking the case of formula (A) as an example, a halogen atom, a cycloalkyl group, an aryl group, and an ester group can be mentioned. The alkyl group includes those substituted by halogen such as F, Cℓ, and Br (e.g., -C 2 HF 4 , -C 5 H 3 F 8 , -C 6 H 3 F 10 , -C 2 H 4 Cℓ, -C 3 H 5 Cℓ, -C 3 H 5 Cℓ 2 , -C 3 H 5 CℓBr, and -C 3 H 5 Br 2 ) cycloalkyl group (e.g., an ester of malic acid (e.g., -CH 2 CH(OH)-COOC 6 H 13 ), and an ester of tartalic acid (eg., -CH(OH)CH(OH)COOC 8 H 17 , In formula (B) and (C), the same substituent as in alkyl group of formula (A) may be substituted. Cycloalkyl group represented by W 1 , W 2 , or W 3 includes, for example, and substituted cyclohexyl group includes, for example, Aryl group represented by W 1 , W 2 , or W 3 includes, for example, and substituted aryl group includes, for example, Alkenyl group includes, for example, -C 4 H 7 , -C 5 H 9 , -C 6 H 11 , -C 7 H 13 , -C 8 H 15 , -C 10 H 19 , -C 12 H 23 , and -C 18 H 35 , and substituted alkenyl grup includes, for example, substtution product of halogen atom (e.g., F, Cℓ, The dielectric constant of these high-boiling solvents of the present invention is more preferably in a range of 3.80 to 5.50. Specific examples of high-boiling solvent represented by formula (A), (B), or (C) are shown below. (P― 1 ) O=P(OC 4 H 9 -n) 3 (P― 3 ) O=P(OC 6 H 13 ―n) 3 (P― 6 ) O=P(OC 8 H 17 ―n) 3 (P― 10 ) O=P(OC 9 H 19 ―n) 3 As the high-boiling organic solvent used in the present invention, any compound other than compounds represented by formulae (A ) to (E ) can also be used if the compound has a melting point of 100°C or below and a boiling point of 140°C or over, and if the compound is substantially immiscible with water and is a good solvent for the coupler. Preferably the melting point of the high-boiling organic solvent is 80°C or below. Preferably the boiling point of the high-boiling organic solvent is 160°C or over, and more preferably 170°C or over. Details of these high-boiling organic solvents are described in JP-A No. 215272/1987, page 137 (the right lower column) to page 144 (the right upper column). Herein, with respect to the high-boiling organic solvent used in the present invention, therm "substantially immiscible with water" means that the solubility to water at 25°C is 5 weight % or below, and preferably 3 weight% or below. Although the amount of high-boiling organic solvent to be used in the present invention may be any amount corresponding to the kind and amount of a coupler, preferably the weight ratio of high-boiling organic solvent to the coupler may be 0.05 to 20. Although presence of at least one emulsion layer containing the high-boiling organic solvent is enough for the color photographic material, preferably it is contained in all emulsion layers. And more preferably the high-boiling solvent is used in layers containing lipophilic material other than emulsion layer. Further, the high-boiling solvent used in the present invention can be used alone or by being mixed. Further, without impairing the effects of the present invention, compounds other than those defined in the present invention can be used in mixture as a high-boiling solvent. The dielectric constant of the above-mentioned organic solvent is preferably in a range of 3.7 to 6.0. The couplers can also be emulsified and dispersed into an aqueous hydrophilic colloid solution by impregnating them into a loadable latex polymer (e.g., U.S. Patent No. 4,203,716) in the presence or absence of the above-mentioned high-boiling organic solvent, or by dissolving them in a polymer insoluble in water and soluble in organic solvents. Preferably, homopolymers and copolymers described in International Publication Patent No. WO 88/00723, pages 12 to 30, are used, and particularly the use of acrylamide polymers is preferable because, for example, dye images are stabilized. The photographic material that is prepared by using the present invention may contain, as color antifoggant, for example, a hydroquinone derivative, an aminophenol derivative, a gallic acid derivative, or an ascorbic acid derivative. In the photographic material used in the present invention, various anti-fading agent (discoloration preventing agent) can be used. That is, as organic anti-fading additives for cyan, magenta and/or yellow images, hydroquinones, 6-hydroxychromans, 6-hydroxycoumarans, spirochromans, p-alkoxyphenols, hindered phenols, including bisphenols, gallic acid derivatives, methylenedioxybenzenes, aminophenols, hindered amines, and ether or ester derivatives obtained by silylating or alkylating the phenolic hydroxyl group of these compounds can be mentioned typically. Metal complexes such as (bissalicylaldoximato)nickel complex and (bis-N,N-dialkyldithiocarbamato)nickel complexes can also be used. Specific examples of the organic anti-fading agents are described in the following patent specifications: Hydroquinones are described, for example, in U.S. Patent Nos. 2,360,290, 2,418,613, 2,700,453, 2,701,197, 2,728,659, 2,732,300, 2,735,765, 3,982,944, and 4,430,425, British Patent No. 1,363,921, and U.S. Patent Nos. 2,710,801 and 2,816,028; 6-hydroxychromans, 5-hydroxycoumarans, and spirochromans are described, for example, in U.S. Patent Nos. 3,432,300, 3,573,050, 3,574,627, 3,698,909, and 3,764,337 and JP-A No. 152225/1987; spiroindanes are described in U.S. Patent No. 4,360,589; p-alkoxyphenols are described, for example, in U.S. Patent No. 2,735,765, British Patent No. 2,066,975, JP-A No. 10539/1984, and JP-B No. 19765/1982; hindered phenols are described, for example, in U.S. Patent Nos. 3,700,455, JP-A No. 72224/1977, U.S. Patent No. 4,228,235, and JP-B No. 6623/1977; gallic acid derivatives, methylenedioxybenzenes, and aminophenols are described, for example, in U.S. Patent Nos. 3,457,079 and 4,332,886, and JP-B No. 21144/1981 respectively; hindered amines are described, for example, in U.S. Patent Nos. 3,336,135, 4,268,593, British Patent Nos. 1,326,889, 1,354,313, and 1,410,846, JP-B No. 1420/1976, and JP-A Nos. 114036/1983, 53846/1984, and 78344/1984; and metal complexes are described, for example, in U.S. Patent Nos. 4,050,938 and 4,241,155 and British Patent 2,027,731(A). To attain the purpose, these compounds can be added to the photosensitive layers by coemulsifying them with the corresponding couplers, with the amount of each compound being generally 5 to 100 wt.% for the particular coupler. To prevent the cyan dye image from being deteriorated by heat, and in particular light, it is more effective to introduce an ultraviolet absorber into the cyan color-forming layer and the opposite layers adjacent to the cyan color-forming layers. As the ultraviolet absorber, aryl-substituted benzotriazole compounds (e.g., those described in U.S. Patent No. 3,533,794), 4-thiazolidone compounds (e.g., those described in U.S. Patent Nos. 3,314,794 and 3,352,681), benzophenone compounds (e.g., those described in JP-A No. 2784/1971), cinnamic acid ester compounds (e.g., those described in U.S. Patent Nos. 3,705,805 and 3,707,395), butadiene compounds (e.g., those described in U.S. Patent No. 4,045,229), or benzoxazole compounds (e.g., those described in U.S. Patent Nos. 3,406,070, 3,677,672, and 4,271,207) can be used. Ultraviolet-absorptive couplers (e.g., α-naphthol type cyan dye forming couplers) and ultraviolet-absorptive polymers can, for example, be used also. These ultraviolet-absorbers may be mordanted in a particular layer. In particular, the above-mentioned aryl-substituted benzotriazole compounds are preferable. In the present invention, together with the above couplers, in particular together with the pyrazoloazole coupler, the following compounds are preferably used. That is, it is preferred that a compound (F), which will chemically bond to the aromatic amide developing agent remaining after the color-developing process, to form a chemically inactive and substantially colorless compound, and/or a compound (G), which will chemically bond to the oxidized product of the aromatic amide color developing agent remaining after the color-developing process, to form a chemically inactive and substantially colorless compound, are used simultaneously or separately, for example, to prevent the occurrence of stain due to the formation of a color-developed dye by the reaction of the couplers with the color-developing agent remaining in the film during storage after the processing or with the oxidized product of the color-developing agent, and to prevent other side effects. Preferable as compound (F) are those that can react with p-anisidine a the second-order reaction-specific rate k2 (in trioctyl phosphate at 80°C) in the range of 1.0 ℓ/mol·sec to 1 x 10 -5 ℓ/mol·sec. The second-order reaction- specific rate can be determined by the method described in JP-A No. 158545/1983. If k2 is over this range, the compound itself becomes unstable, and in some cases the compound reacts with gelatin or water to decompose. On the other hand, if k 2 is below this range, the reaction with the remaining aromatic amine developing agent becomes slow, resulting, in some cases, in the failure to prevent the side effects of the remaining aromatic amine developing agent, which prevention is aimed at by the present invention. More preferable as compound (F) are those that can be represented by the following formula (FI) or (FII): Formula (FI) R 31 - (A) n - X 31 wherein R 31 and R 32 each represent an aliphatic group, an aromatic group, or a heterocyclic group, n is 1 or 0, A represents a group that will react with an aromatic amine developing agent to form a chemical bond therewith, X 31 represents a group that will react with the aromatic amine developing agent and split off, B represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, an acyl group, or a sulfonyl group, Y represents a group that will facilitate the addition of the aromatic amine developing agent to the compound represented by formula (FII), and R 31 and X 31 , or Y 32 and R 32 or B, may bond together to form a ring structure. Of the processes wherein compound (F) bonds chemically to the remaining aromatic amine developing agent, typical processes are a substitution reaction and an addition reaction. Specific examples of the compounds represented by formulae (FI), and (FII) are described, for example, in JP-A Nos. 158545/1988, 28338/1987, 2042/1989, and 86139/1989. On the other hand, more preferable examples of compound (G), which will chemically bond to the oxidized product of the aromatic amine developing agent remaining after color development processing, to form a chemically inactive and colorless compound, can be represented by the following formula (GI): Formula (GI) R 33 - Z 33 wherein R 33 represents an aliphatic group, an aromatic group, or a heterocyclic group, Z 33 represents a nucleophilic group or a group that will decompose in the photographic material to release a nucleophilic group. Preferably the compounds represented by formula (GI) are ones wherein Z represents a group whose Pearson's nucleophilic n CH 3 I value (R.G. Pearson, et al., J. Am. Chem. Soc ., 90 , 319 (1968)) is 5 or over, or a group derived therefrom. Specific examples of compounds represented by formula (GI) are described, for example, in European published Patent No. 255722, JP-A Nos. 143048/1987, 229145/1987, 230039/1989, and 57259/1989, andEuropean Published Patent Nos. 298321 and 277589. Details of combinations of compound (G) and compound (F) are described in European Published Patent No. 277589. The photographic material to be used in the present invention may contain, in the hydrophilic colloid layer, water-soluble dyes as filter dyes or to prevent irradiation, and for other purposes. Such dyes include oxonol dyes, hemioxonol dyes, styryl dyes, merocyanine dyes, cyanine dyes, and azo dyes. Among others, oxonol dyes, hemioxonol dyes, and merocyanine dyes are useful. As a binder or a protective colloid that can be used in the emulsion layers of the present photographic material, gelatin is advantageously used, but other hydrophilic colloids can be used alone or in combination with gelatin. In the present invention, gelatin may be lime-treated gelatin or acid-processed gelatin. Details of the manufacture of gelatin is described by Arthur Veis in The Macromolecular Chemistry of Gelatin (published by Academic Press, 1964). As a base to be used in the present invention, a transparent film, such as cellulose nitrate film, and polyethylene terephthalate film or a reflection-type base that is generally used in photographic materials can be used. The use of a reflection-type base is more preferable. The "reflection base" is one that enhances reflectivity, thereby making sharper the dye image formed in the silver halide emulsion layer, and it includes one having a base coated with a hydrophobic resin containing a dispersed light- reflective substance, such as titanium oxide, zinc oxide, calcium carbonate, and calcium sulfate, and also a base made of a hydrophobic resin containing a dispersed light- reflective substance. For example, there can be mentioned baryta paper, polyethylene-coated paper, polypropylene- type synthetic paper, a transparent base having a reflective layer, or additionally using a reflective substance, such as glass plate, polyester films of polyethylene terephthalate, cellulose triacetate, or cellulose nitrate, polyamide film, polycarbonate film,polystyrene film, and vinyl chloride resin. As the other reflection base, a base having a metal surface of mirror reflection or secondary diffuse reflection may be used. A metal surface having a spectral reflectance in the visible wavelength region of 0.5 or more is preferable and the surface is preferably made to show diffuse reflection by roughening the surface or by using a metal powder. The surface may be a metal plate, metal foil or metal thin layer obtained by rolling, vapor deposition or galvanizing of metal such as, for example, aluminum, tin, silver, magnesium and alloy thereof. Of these, a base obtained by vapor deposition of metal is preferable. It is preferable to provide a layer of water resistant resin, in particular, a layer of thermoplastic resin. The opposite side to metal surface side of the base according to the present invention is preferably provided with an antistatic layer. The details of such base are described, for example, in JP-A Nos. 210346/1986, 24247/1988, 24251/1988 and 24255/1988. It is advantageous that, as the light-reflective substance, a white pigment is kneaded well in the presence of a surface-active agent, and it is preferable that the surface of the pigment particles has been treated with a divalent to tetravalent alcohol. The occupied area ratio (%) per unit area prescribed for the white pigments finely divided particles can be obtained most typically by dividing the observed area into contiguous unit areas of 6 µm x 6 µm, and measuring the occupied area ratio (%) (Ri) of the finely divided particles projected onto the unit areas. The deviation coefficient of the occupied area ratio (%) can be obtained based on the ratio s/ R , wherein s stands for the standard deviation of Ri, and R stands for the average value of Ri. Preferably, the number (n) of the unit areas to be subjected is 6 or over. Therefore, the deviation coefficient s/ R can be obtained by In the present invention, preferably the deviation coefficient of the occupied area ratio (%) of the finely divided particles of a pigment is 0.15 or below, and particularly 0.12 or below. If the variation coefficient is 0.08 or below, it can be considered that the substantial dispersibility of the particles is substantially "uniform." Next, the present invention will be described in detail by the following examples. Example 1 A multilayer color photographic paper was prepared by coating layers as hereinbelow described on a paper laminated on both sides with polyethylene. Coating solutions were prepared as follows: Preparation of the first-layer coating solution To a mixture of 60.0 g of yellow coupler (ExY) and 28.0 g of discoloration inhibitor (Cpd-1), 150 mℓ of ethyl acetate, 1.0 mℓ of solvent (Solv-3) and 3.0 mℓ of solvent (Solv-4) were added and dissolved. The resulting solution was added to 450 mℓ of 10 % aqueous gelatin solution, and then the mixture was dispersed by a supersonic homogenizer. The resulting dispersion was mixed with and dissolved in 420 g of silver chloro-bromide emulsion (silver bromide : 0.7 mol%) containing a blue-sensitive sensitizing dye, described below, to prepare the first-layer coasting solution. Coating solutions for the second to seventh layers were also prepared in the same manner as in the first layer coating solution. As a gelatin hardener for the respective layers, 1,2-bis(vinylsulfonyl)ethane was used. As spectral sensitizers for the respective layers, the following compounds were used: Blue-sensitive emulsion layer: Anhydro-5,5'-dichloro-3,3'-disulfoethylthia-cyanine hydroxide Green-sensitive emulsion layer: Anhydro-9-ethyl-5,5'-diphenyl-3,3'-disulfoethyloxacarbocyanine hydroxide Red-sensitive emulsion layer: 3,3'-Diethyl-5-methoxy-9,9'-(2,2'-dimethyl-1,3-propano)thiacarbocyanine iodide As a stabilizer for the respective emulsion layer, a mixture (7 : 2 : 1 in molar ratio) of the following compounds was used: 1-(2-Acetoaminophenyl)-5-mercaptotetrazole, 1-Phenyl-5-mercaptotetrazole, and 1-(p-Methoxyphenyl)-5-mercaptotetrazole As irradiation preventing dyes the following compounds were used: [3-Carboxy-5-hydroxy-4-(3-(3-carboxy-5-oxo-1-(2,5-sulfonatophenyl)-2-pyrazoline-4-iridene)-1-propenyl)-1-pyrazolyl]benzene-2,5-disulfonatedisodium salt, N,N'-(4,8-Dihydroxy-9,10-dioxo-3,7-disulfonatoanthracene-1,5-diyl)bis(aminomethanesulfonate)tetrasodium salt, and [3-Cyano-5-hydroxy-4-(3-(3-cyano-5-oxo-1-(4-sulfonatophenyl)-2-pyrazoline-4-iridene)-1-pentanyl)-1-pyrazolyl]benzene-4-sulfonato-sodium salt (Composition of layers) The composition of each layer is shown below.

The coated sample 101 was subjected to the test described below using color developer shown below. First, sample above described was subjected to a gradation exposure to light for sensitometry using a sensitometer (FWH model by Fuji Photo Film Co., Ltd., the color temperature of light source was 3200 K). At that time, the exposure was carried out in such a manner that the exposure was 250 CMS with the exposure time being 0.1 second. The sample above described was processed by the processing process shown below using processing solutions compositions of which are described below. The composition was changed as shown in Table 1. Processing steps Temperature Time Color developing 38°C 45 sec. Bleach-fixing 37°C 45 sec. Water washing 1 30 - 37°C 30 sec. Water washing 2 30 - 37°C 30 sec. Water washing 3 30 - 37°C 30 sec. Drying 70 - 85°C 60 sec. The compositions of the respective processing solution were as follows: Color developer Water 800 mℓ Additive (see Table 1) 0.15 g Ethylenediaminetetraphosphonic acid 9.4 g 1-Hydroxyethylidene-1,1-dephosphonic acid 0.6 g Triethanolamine 15.0 g Sodium chloride 3.0 g Potassium bromide 0.02 g Potassium carbonate 25 g N-ethyl-N-(β-methanesulfonamidoethyl)-3-methyl-4-aminoaniline sulfate 5.0 g Organic preservative (see Table 1) 0.05 mol Sodium sulfite see Table 1 Fluorescent brightening agent (WHITEX-4®, made by Sumitomo Chem. Ind.) 1.0 g Water to make 1000 mℓ pH (25°C) 10.0 Bleach-fixing solution Water 400 mℓ Ammonium thiosulfate (70 %) 100 mℓ Sodium sulfite 38 g Iron (III) ammonium ethylene-diaminetetraacetate 55 g Disodium ethylenediaminetetraacetate 5 g Ammonium bromide 40 g Glacial acetic acid 9 g Water to make 1000 mℓ pH (25°C) 5.40 Rinsing solution (both tank solution and replenisher) Ion-exchanged water (calcium and magnesium each were contained in a concentration of 3 ppm or below) Said color developer was aged for 20 days at a constant temperature of 40°C with an open area of 25 cm 2 per liter in contact with air. At the start of the above aging, said sensitometry was processed, and the maximum density of cyan color formation was measured by a Macbeth densitometer to assess the color-forming property of the color developer. Then after the completion of the aging, said sensitometry was processed and the minimum density of the yellow was measured, and then to remove the tarry stain of the coated sample, the sample was dipped in a 5 % aqueous acetic acid solution for 5 min and the yellow minimum density was again measured. Thus, the yellow minimum density difference before and after the acid washing of the coated sample was measured to assess the degree of staining of the white background of the coated sample. Further, it was observed visually whether the color developer after the aging was colored or formed a tarry contaminant. The results are summarized in Table 1. As is apparent from Table 1, when the constitutional requirements of the present invention are satisfied, a color image high in maximum density and excellent in whiteness is obtained with the contamination of the color developer after aging being less, thereby attaining the objects of the present invention (Experiment Nos. 11, 12, 15 to 22). If the compounds of formulae (I) and (II) and a sulfite are not contained, irrespective of the presence or absence of a polymer, an increase in yellow minimum density (ΔDmin) is great and the coloration and the formation of a tarry contaminant of the color developer are great, which is far from attaining the objects of the present invention (Experiment Nos. 1 to 3). When the polymer used in the present invention is not contained and a sulfite is not also contained, irrespective of the presence or absence of the compounds of formulae (I) and (II), the increase in yellow minimum density (ΔDmin) is great and the coloration and the formation of a tarry contaminant of the color developer are great, which is far from attaining the objects of the present invention (Experiment Nos. 3, 5, 8, and 9). When a sulfite is contained in the color developer, irrespective of the presence or absence of the compounds of formulae (I) and (II) and a polymer, the increase in yellow minimum density and the coloration and the formation of a tarry contaminant are little but the maximum density is low, which is far from attaining the objects of the present invention. Experiments 4 to 7 Thus, when the constitutional requirements of the present invention are simultaneously satisfied, the effect of the present invention is exhibited, so that the uniqueness of the combination of the constitutional requirements of the present invention can be understood. Although the density difference in the yellow minimum density increase between Experiment Nos. 1 and 10 is 0.03, which is very little, when their white backgrounds are compared visually, their whiteness is clearly different. An increase of 0.03 or more in minimum density is of practical significance, and an increase of 0.05 or more falls in such a range that it loses its commercial value. Example 2 A multilayer photographic material was prepared by multi-coatings composed of the following layer composition on a two-side polyethylene laminated paper support. Coating solutions were prepared as follows: Preparation of the first layer coating solution To a mixture of 19.1 g of yellow coupler (ExY), 4.4 g of image-dye stabilizer (Cpd-1) and 0.7 g of image-dye stabilizer (Cpd-7), 27.2 mℓ of ethyl acetate and 8.2 g of solvent (Solv-1) were added and dissolved. The resulting solution was dispersed and emulsified in 185 mℓ of 10 % aqueous gelatin solution containing 8 mℓ of sodium dodecylbenzenesulfonate. Separately another emulsion was prepared by adding two kinds of blue-sensitive sensitizing dye, shown below, to a silver chlorobromide emulsion (cubic grains, having 0.82 µm of average grain size, and 0.08 of deviation coefficient of grain size distribution, in which 0.2 mol% of silver bromide was located at the surface of grains) in such amounts that each dye corresponds 2.0 x 10 -4 mol per mol of silver, and then sulfur-sensitized. The thus-prepared emulsion and the above-obtained emulsified dispersion were mixed together and dissolved to give the composition shown below, thereby preparing the first layer coating solution. Coating solutions for the second to seventh layers were also prepared in the same manner as the first-layer coating solution. As a gelatin hardener for the respective layers, 1-hydroxy-3,5-dichloro-s-treazine sodium salt was used. As spectral-sensitizing dyes for the respective layers, the following compounds were used: To the red-sensitive emulsion layer, the following compound was added in an amount of 2.6 x 10 -3 mol per mol of silver halide: Further, 1-(5-methylureidophenyl)-5-mercaptotetrazole was added to the blue-sensitive emulsion layer, the green-sensitive emulsion layer, and the red-sensitive emulsion layer in amount of 8.5 x 10 -5 mol, 7.7 x 10 -4 mol, and 2.5 x 10 -4 mol, per mol of silver halide, respectively. Further, 4-hydroxyl-6-methyl-1,3,3a,7-tetrazaindene was added to the blue-sensitive emulsion layer and the green-sensitive emulsion layer in amount of 1 x 10 -4 mol and 2 x 10 -4 mol, per mol of silver halide, respectively.

Each overflowed solution was regenerated by the method shown below, and was reused as a replenishing solution. Regeneration of bleaching solution Chemicals shown below were added to 10 liter of overflowed solution, and the pH of solution was adjusted to 4.5. Fe(III) ammonium ethylenediaminetetraacetate 100 g Ethylenediaminetetraacetic acid 10 g Ammonium bromide 150 g Nitric acid 30 g Regenerated solution obtained was used as a replenishing solution.

At that point, the concentration of total iron ions was measured by an atomic absorption spectrometry. The concentration of Fe(II) complex was measured by a colring method using basophenanthroline. As a result, it was that the ratio of Fe(II) complex was 30 %. According to the processings of the present invention, minimum density and the amount of residual silver were made very low and good color image was obtained when the ratio of Fe (II) was 3 to 30 %. Further, in such processing as this, good results can be obtained by using the compound of the present invention. Sample A was exposed to light through an wedge and processed by using above-described processing solutions. Mimimum density of magenta at unexposed part of processed sample was measured by Macbeth densitometer to evaluate bleach-fogging. Further, the amount of residual silver at the maximum exposed part was measured by a flurescent X-ray method. Next, the concentration of Fe(II) in bleaching solution was reduced by bubbling of air into the tank of bleaching solution and, at the same time, sample A was treated in the same manner as descrived above. Thus the relation of bleach-fogging and desilvering property to the ratio of Fe(II) complex were determined. Results are shown in Table 4.
