In the method, processing solutions having a fixing ability have improved stability with time during continuous processing and exhibit excellent desilvering performance. The method provides an image showing a reduced increase in stain with time and realizes improvements of the working environment.

Description: This invention relates to methods for processing a silver halide photographic material which reduce the deterioration of processing solutions with the passage of time during continuous processing, exhibit excellent desilvering properties, provide an image showing a reduced increase in stain with the passage of time, and achieve improvements in the working environment. In the photographic processing of silver halide light-sensitive materials, an important object has been to provide a satisfactory photographic image in a stable manner. This object has become more difficult to accomplish particularly in view of the latest requirements for speeding up of processing and reducing the rate of replenishment so that the amount of waste liquid can be reduced. For obtaining a satisfactory photographic image in a stable manner, the most significant factor is for photographic processing solutions to be stable against deterioration with the passage of time, such as by air oxidation. In particular, in the current color photographic processing systems where reduction of washing water or stabilizing processing has become widespread, improvement in the stability of the bleach-fixing or fixing bath and the subsequent washing or stabilizing bath is of extreme importance. Carbonyl-bisulfite addition compounds have hitherto been proposed as a preservative and as a means for improving the stability of a bleach-fixing or fixing bath. For example, methods of using these carbonyl-bisulfite addition compounds as a preservative for a bleach-fixing or fixing bath are described in JP-A-48-42733 (the term "JP-A" as used herein means an "unexamined published Japanese patent application"), JP-A-50-51326, JP-A-56-107244, and DE-B-2,102,713. However, although carbonyl-bisulfite addition compounds exhibit excellent performance as a preservative for a bleach-fixing or fixing bath, they have not yet been practically used because various problems arise in their use. In particular, when a conventional photographic light-sensitive material is processed with a bleach-fixing bath containing a carbonyl-bisulfite addition compound as a preservative, the resulting image has deteriorated preservability. That is, when the processed light-sensitive material is stored, the minimum density on the undeveloped area (D min ) increases with the passage of time and stain is generated. Moreover, lower aliphatic aldehydes, of the available carbonyl compounds, have a low vapor pressure and therefore give rise to handling problems and environmental problems, such as odor. Hence, there has been a strong desire for a method of processing a silver halide color photographic material in which a bleach-fixing or fixing bath exhibits excellent stability without causing deterioration of the resulting image with the passage of time or any other problems occurring. On the other hand, it is known to add a specific sulfinic acid to a processing solution as disclosed, for example, in JP-B-49-33787 (the term "JP-B" as used herein means an "examined Japanese patent publication"), GB-B-571,078, and US-A-3,293,036. JP-B-49-33787 relates to black-and-white development, and GB-B-571,078 relates to silver dye bleaching, both differing from the present invention in object of using a sulfinic acid and containing no disclosure at all as to stain prevention of color light-sensitive materials. Further, the compounds disclosed in US-A-3,293,036 have been found not to produce any effect on image stain generated with the passage of time. Although GB-B-1,379,615 states that the sulfinic acid can be used to improve the stability of a bleach-fixing bath per se , there is no suggestion as to stain prevention of color light-sensitive materials. In addition, JP-A-1-230039 describes the use of a sulfinic acid for stabilizing a processing solution and for prevention of stain of color light-sensitive materials. However, the effects produced are insufficient, or the solubility of the sulfinic acid in a processing solution is insufficient. It has been proposed to conduct bleaching or bleach-fixing by replacing conventionally employed (ethylenediaminetetraacetato)iron (III) complexes with a bleaching agent having a higher oxidizing power thereby to shorten the processing time or to reduce the amount of waste liquid. That is, use of a powerful oxidizing agent as a bleaching agent is expected to increase the rate of bleaching reaction to thereby achieve rapid bleaching or bleach-fixing. It is also expected that a bleaching bath or a bleach-fixing bath maintains a high bleaching ability even if it is fatigued due to consumption of the oxidizing agent (bleaching agent) and accumulation of silver ion and halogen ion as the processing progresses thereby to decrease the amount of replenisher needed. It has turned out, however, that such a powerful oxidizing agent (bleaching agent), when employed in a bleaching bath, diminishes the stability of the succeeding fixing bath with the passage of time due to the carry-over, or, when used in a bleach-fixing bath, considerably reduces the stability of the bleach-fixing bath per se with the passage of time, thus retarding the bleach-desilvering reaction. As a result, the succeeding washing or stabilizing bath also has reduced stability with the passage of time. It has thus been demanded to develop a technique for improving the stability of a bleach-fixing bath or a fixing bath with time. It has been proposed in JP-A-1-267540 to improve the stability of processing solutions by addition of a carbonyl-bisulfite addition compound and a compound having an amino group as a functional group to a bleach-fixing bath. However, the inventors have proved that a processing solution containing a carbonyl-bisulfite addition compound and a compound having an amino group forms a precipitate or a color change to black brown occurs on aging. EP-A-0409 276 which is state of the art under the provisions of Art. 54(3) EPC and, therefore, relevant for novelty considerations only, describes a method for processing an exposed silver halide color photographic material comprising the steps of: (a) color developing an exposed silver halide color photographic material; (b) bleach-fixing said developed material; (c) at least one of washing said bleach-fixed material with water and stabilizing said bleach-fixed material; (d) regenerating a portion of a solution from said step (b) for bleach-fixing to form a replenisher solution comprising at least a carbonyl bisulfite adduct; and (e) replenishing at least one solution in said bleach-fixing step (b) with said replenisher solution from step (d). EP-A-0294 769 describes a method for processing a silver halide photographic material in which a processing solution contains a sulfite and a sulfinic acid. An object of the present invention is to provide a method for processing a silver halide photographic material, in which a fixing bath or a bleach-fixing bath has excellent stability. Another object of the present invention is to provide a fixing bath or a bleach-fixing bath having excellent stability. Still another object of the present invention is to provide a method for processing a silver halide photographic material, which provides a photographic image having excellent preservability. A further object of the present invention is to provide a method for processing a silver halide photographic material, which achieves rapid desilvering. A still further object of the present invention is to provide a method for processing a silver halide photographic material, where environmental pollution does not occur. Yet a further object of the present invention is to provide a method for processing a silver halide photographic material, in which a washing bath or a stabilizing bath has excellent stability with the passage of time. As a result of extensive investigations, it has now been found that the above objects of the present invention are accomplished by using a fixing solution or a bleach-fixing solution with a specific composition.

Specific examples of these buffering agents are sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, sodium tertiary phosphate, potassium tertiary phosphate, sodium secondary phosphate, potassium secondary 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). The buffering agent can be preferably employed in the color developing solution in an amount of 0.1 mol/ℓ or more, and more preferably from 0.1 to 0.4 mol/ℓ. Various chelating agents can be used in the color developing solution to prevent precipitation of calcium or magnesium or to improve the stability of the developing solution. Preferred chelating agents include organic acid compounds, such as aminopolycarboxylic acids, organic phosphonic acids, and phosphonocarboxylic acids. Specific examples of suitable chelating agents include nitrilotriacetic acid, diethylenetriaminepentaacetic acid, ethylenediaminetetraacetic acid, N,N,N-trimethylenephosphonic acid, ethylenediamine-N,N,N',N'-tetramethylenesulfonic acid, trans-cyclohexanediaminetetraacetic acid, 1,2-diaminopropanetetraacetic acid, hydroxyethyliminodiacetic acid, glycol ether diaminetetraacetic acid, ethylenediamine o-hydroxyphenylacetic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, and N,N'-bis(2-hydroxybenzyl)ethylenediamine-N,N'-diacetic acid. These chelating agents may be used either individually or as a combination of two or more thereof. The chelating agent is employed in an amount sufficient for blocking metallic ions in a color developing solution, usually in an amount of from about 0.1 g to about 10 g per liter of the color developing solution. If desired, a developing accelerator may be used in the color developing solution. However, it is preferable in view of the prevention of environmental pollution and color stain and the preparation of the solution that the color developing solution to be used in the present invention contains substantially no benzyl alcohol. The terminology "substantially no benzyl alcohol" as used herein means that the amount of benzyl alcohol is not more than 2 ml/ℓ, and preferably is zero. Examples of suitable developing accelerators include thioether compounds as described in JP-B-37-16088, JP-B-37-5987, JP-B-38-7826, JP-B-44-12380, JP-B-45-9019, and US-A-3,813,247; p-phenylenediamine compounds as described in JP-A-52-49829 and JP-A-50-15554; quaternary ammonium salts as described in JP-A-50-137726, JP-B-44-30074, JP-A-56-156826, and JP-A-52-43429; amine compounds as described in US-A-2,494,903, 3,128,182, 4,230,796, and 3,253,919, JP-B-41-11431, and US-A-2,482,546, 2,596,926, and 3,582,346; polyalkylene oxides as described in JP-B-37-16088, JP-B-42-25201, US-A-3,128,183, JP-B-41-11431, JP-B-42-23883, and US-A-3,532,501; 1-phenyl-3-pyrazolidones; and imidazoles. If desired, an antifoggant may also be employed in the color developing solution. Examples of suitable antifoggants include alkali metal halides, e.g., sodium chloride, potassium bromide and potassium iodide; and organic antifoggants. Typical examples of organic antifoggants are nitrogen-containing heterocyclic compounds, e.g., benzotriazole, 6-nitrobenzimidazole, 5-nitroisoindazole, 5-methylbenzotriazole, 5-nitrobenzotriazole, 5-chlorobenzotriazole, 2-thiazolylbenzimidazole, 2-thiazolylmethylbenzimidazole, indazole, hydroxyazaindolizine, and adenine. The color developing solution may contain a fluorescent brightening agent. Examples of suitable fluorescent brightening agents include 4,4'-diamino-2,2'-disulfostilbene compounds. The fluorescent brightening agent is used in an amount of generally up to 5 g/ℓ, and preferably from 0.1 to 4 g/ℓ. If desired, various surface active agents, such as alkylsulfonic acids, arylsulfonic acids, aliphatic carboxylic acids, and aromatic carboxylic acids, may also be employed in the color developing solution. Development processing with the above-described color developing solution is carried out at a processing temperature usually ranging from 20 to 50°C, and preferably from 30 to 40°C, for a processing time of generally from 20 seconds to 5 minutes, and preferably from 30 seconds to 2 minutes. The rate of replenishment is preferably as small as possible and suitably ranges from 100 to 1,500 mℓ/m 2 , preferably from 100 to 800 mℓ/m 2 , and more preferably from 100 to 400 mℓ/m 2 . If desired, the color developing bath may be separated into two or more baths, and the first or final bath is replenished with a replenisher to thereby reduce the developing time or the rate of replenishment. The method of processing according to the present invention is applicable to color reversal processing. The black-and-white developing solution which can be used in color reversal development is a black-and-white first developing solution which is used in reversal processing of color light-sensitive materials or a developing solution which is used for processing of black-and-white light-sensitive materials. The black-and-white developing solution generally contains various additives commonly employed in the art. Typical additives include developing agents, e.g., 1-phenyl-3-pyrazolidone, metol, and hydroquinone; preservatives, e.g., sulfites; alkali agents, e.g., sodium hydroxide, sodium carbonate, and potassium carbonate; organic or inorganic inhibitors, e.g., potassium bromide, 2-methylbenzimidazole, and methylbenzothiazole; water softeners, e.g., polyphosphates; and development inhibitors, e.g., a trace amount of an iodide, and a mercapto compound. An exposed color light-sensitive material is subjected to color development, desilvering, and washing. Desilvering comprises a bleaching step using a bleaching bath and a fixing step using a fixing bath or bleach-fixing (blixing) step using a bleach-fixing bath. These steps may be used in various orders to complete desilvering as follows. 1) Bleaching/fixing 2) Bleaching/bleach-fixing 3) Bleaching/bleach-fixing/fixing 4) Bleaching/washing/fixing 5) Bleaching/fixing/fixing 6) Bleach-fixing 7) Bleach-fixing/bleach-fixing The color developed light-sensitive material may be directly subjected to bleaching or bleach-fixing without any intermediate step. Alternatively, the color developed light-sensitive material may be subjected to an intermediate step, such as stopping, compensation development, and washing, prior to bleaching or bleach-fixing for the purpose of preventing unnecessary post development and aerial fog and reducing the carry-over of a color developing solution into the desilvering step or for the purpose of washing out components of the light-sensitive material, e.g., sensitizing dyes and dyes, and color developing agent impregnated in a light-sensitive material to eliminate the adverse influences of these components. If desired, washing may be followed by stabilizing, or washing may be replaced by stabilizing. These steps may be combined with prehardening, neutralizing, stop-fixing, and the like. Washing or rinsing may be conducted between these steps, if desired. Replenishment in desilvering is usually carried out by supplying a replenisher to a processing solution, while discarding the overflow as a waste liquid. Replenishment may be effected by a cocurrent system in which an overflow of a prebath is introduced into a succeeding bath, or a countercurrent system in which an overflow of a succeeding bath is introduced into a prebath. For example, the overflow from a washing or stabilizing bath can be returned to a fixing bath or a bleach-fixing bath. The effects of the present invention are achieved to a much greater extent as the total time of desilvering is decreased. The preferred total time for desilvering is generally from 1 to 10 minutes, and more preferably from 1 to 6 minutes. The processing temperature of desilvering is generally from 25 to 50°C, and preferably from 35 to 45°C. Within the preferred temperature range, the rate of desilvering increases, and stain formation after processing can be effectively prevented. It is desirable that desilvering should be performed under good stirring. Methods for achieving good stirring include a method in which a stream of a processing solution is jetted against the surface of the emulsion layer as described in JP-A-62-183460, JP-A-62-183461, and US-A-4,758,858; a method of using a rotating means to enhance the stirring effects as described in JP-A-62-183461; a method in which a light-sensitive material is moved with its emulsion surface in contact with a wire blade placed in a processing solution to create a turbulence; and a method of increasing a total flow of circulating processing solution. These stirring means are effective in any of a bleaching bath, a bleach-fixing bath and a fixing bath. Enhanced stirring appears to accelerate the supply of the bleaching agent or the fixing agent into the emulsion layers and, as a result, to increase the rate of desilvering. The above-described means for improved stirring is more effective where a bleaching accelerator is used, markedly enhancing the acceleration effects and eliminating the inhibitory effect on fixing of the bleaching accelerator. An automatic developing machine which can be used in the present invention preferably has a means for conveying a light-sensitive material as described in JP-A-60-191257, JP-A-60-191258, JP-A-60-191259, Research Disclosure , No. 29118 (Jul., 1988), and US-A-4,758,858. As mentioned in JP-A-60-191257 supra , such a conveying means is effective to considerably reduce carry-over of a processing solution from a prior bath into a succeeding bath thereby to prevent a reduction of processing capacity. The means described in Research Disclosure , No. 29118 is also preferred. These means are particularly effective to achieve a reduction in the processing time or replenishment rate in each processing step. The above-described means for enhanced stirring is effective not only in desilvering but also in washing and development to reduce the processing time and the rate of replenishment. While bleach-fixing or fixing is generally followed by washing and stabilizing, a simplified method may be used, in which the processing in a processing solution having fixing ability is followed directly by stabilizing without any substantial amount of washing being conducted. Water to be used for washing may contain various known additives if desired. Suitable additives include hard water softeners, e.g., inorganic phosphonic acids, aminopolycarboxylic acids, and organic phosphonic acids; bactericides or antifungal agents for preventing growth of various bacteria or algae (e.g., isothiazolone, chlorinated organic compounds, benzotriazoles), and surface active agents for reducing the drying load and drying unevenness. The compounds described in L.E. West, Water Quality Criteria , Photo. Sci. and Eng., Vol. 9, No. 6, pp. 344-359 (1965) are also useful. A stabilizing bath used for stabilizing is a processing solution for stabilizing a dye image, including a solution providing buffering at a pH of 3 to 6, and a solution containing an aldehyde (e.g., glutaraldehyde). Formaldehyde is disadvantageous from the standpoint of environmental pollution. If desired, the stabilizing bath may contain an ammonium compound, a metallic compound (e.g., Bi compounds, Aℓ compounds), a fluorescent brightening agent, a chelating agent (e.g., EDTA, 1-hydroxyethylidene-1,1-diphosphonic acid), a bactericide, an antifungal agent, a hardening agent, and a surface active agent. Examples of effective antifungal agents include thiazolone compounds, e.g., 5-chloro-2-methylisothiazolin-3-one and 1,2-benzisothiazolin-3-one. Preferred surface active agents are silicone compounds represented by the formula shown below because of their effects in preventing water spots and defoaming effects. wherein a, b, d, and e each represents an integer of from 5 to 30; c represents an integer of from 2 to 5; and R represents an alkyl group having from 3 to 6 carbon atoms. The stabilizing bath preferably contains an alkanolamine for preventing sulfuration of thiosulfate ion which has been brought in with the light-sensitive material. The details of use of alkanolamines are described in US-A-4,786,583. Use of formaldehyde which is generally added to a stabilizing bath is not preferred in the present invention. The stabilizing bath has a pH of generally from 3 to 8, and preferably from 5 to 7, and the temperature is generally from 5 to 45°C, and preferably from 10 to 40°C. Washing and/or stabilizing is preferably carried out in a multi-stage countercurrent system using 2 to 4 stages. Two or more stabilizing baths may be used in multiple stages. The amount of a replenisher is generally from 1 to 50 times, preferably from 2 to 30 times, and more preferably from 2 to 15 times, the carry-over per unit area from a prior bath. The effects of the present invention are accomplished to a greater extent with decreased time of washing or stabilizing. From the standpoint of rapid processing, the total time required for washing and stabilizing is preferably from 10 to 50 seconds, and particularly preferably from 10 to 30 seconds. The smaller the rate of replenishment in washing or stabilizing, the greater the effects of the present invention. A preferred rate of replenishment ranges from 50 to 400 mℓ, and particularly from 50 to 200 mℓ, per m 2 of the light-sensitive material. Water which can be used in washing or stabilizing includes tap water, deionized water having Ca and Mg concentrations each reduced to 5 mg/ℓ or less by treatment with an ion-exchange resin, etc., and water sterilized by a ultraviolet germicidal lamp. Where each of the above-described processing steps is conducted in a continuous manner using an automatic developing machine, the processing solution tends to become concentrated due to evaporation, which is particularly conspicuous when a small amount of light-sensitive material is processed or when the processing tank has a wide open area. Such being the case, it is desirable to supply an adequate amount of water or a replenisher to make up for the loss due to vaporization. It is possible to reduce the amount of waste liquid by recycling the overflow from the washing or stabilizing bath to a preceding bath having a fixing ability. The color light-sensitive material generally contains yellow couplers, magenta couplers, and cyan couplers which develop a yellow, magenta, and cyan color, respectively, on coupling with an oxidation product of an aromatic amine color developing agent.

When two or more substituents are present, they may be the same or different. R 8' preferably represents a hydrogen atom, an aliphatic acyl group, or an aliphatic sulfonyl group, and more preferably a hydrogen atom. Y c' preferably represents a group releasable at any of sulfur, oxygen and nitrogen atoms.

Imidazo[1,2-b]pyrazoles described in US-A-4,500,630 are preferred of the pyrazoloazole couplers of formula (M-II), in view of the reduced yellow side absorption and fastness to light. Pyrazolo[1,5-b][1,2,4]triazoles described in US-A-4,540,654 are particularly preferred. Additional examples of suitable pyrazoloazole couplers include pyrazolotriazole couplers having a branched alkyl group at the 2-, 3- or 6-position of the pyrazolotriazole ring as described in JP-A-61-65245; pyrazoloazole couplers containing a sulfonamido group in the molecule thereof as described in JP-A-61-65246; pyrazoloazole couplers having an alkoxyphenylsulfonamido ballast group as described in JP-A-61-147254; and pyrazolotriazole couplers having an alkoxy group or an aryloxy group at the 6-position as described in European Patent Publication Nos. 226,849 and 294,785.

Specific examples of couplers represented by formulae (C-I), (C-II), (M-I), (M-II), and (Y) which can be used are shown below. The couplers can be incorporated into silver halide emulsion layers using known methods, e.g., the method of US-A-2,322,027. For example, the coupler can be dissolved in a high-boiling point organic solvent, such as alkyl phthalates (e.g., dibutyl phthalate, dioctyl phthalate), phosphoric esters (e.g., diphenyl phosphate, triphenyl phosphate, tricresyl phosphate, dioctylbutyl phosphate), citric esters (e.g., acetyl tributyl citrate), benzoic esters (e.g., octyl benzoate), alkylamides (e.g., diethyllaurylamide), and fatty acid esters (e.g., dibutoxyethyl succinate, dioctylazelate), or a low-boiling point organic solvent having a boiling point of from about 30° to 150°C, such as lower alkyl acetates (e.g., ethyl acetate, butyl acetate), ethyl propionate, sec-butyl alcohol, methyl isobutyl ketone, β-ethoxyethyl acetate, and methyl Cellosolve acetate, and the resulting solution is dispersed in a hydrophilic colloid. The above-described high-boiling organic solvent and low-boiling point organic solvent may be used in combination, if desired. For the details of the high-boiling point organic solvents, reference can be made in JP-A-62-215272. Other usable high-boiling organic solvents which can be effectively used for dissolving the couplers include N,N-dialkylaniline derivatives. Of them, those having an alkoxy group at the o-position of the N,N-dialkylamino group thereof are preferred. Examples of suitable compounds are represented by the following formula: High-boiling organic solvents of the above formula are effective to prevent formation of magenta stain on white background of color prints with time and also to prevent fog due to development. The N,N-dialkylaniline derivative as a solvent is usually used in an amount of from 10 to 500 mol%, and preferably from 20 to 300 mol, based on the coupler. It is also possible to impregnate the coupler into a loadable latex polymer (described, e.g., in US-A-4,203,716) in the presence or absence of the above-described high-boiling point organic solvent or dissolved in a water-insoluble and organic solvent-soluble polymer and emulsified and dispersed in a hydrophilic colloid aqueous solution. The homo- or copolymers described in WO 88/00723, pp. 12-30 are preferably employed. In particular, acrylamide polymers are preferred from the standpoint of dye image stability. A dispersion method using a polymer as described in JP-B-51-39853 and JP-A-51-59943 can also be employed. Couplers having an acid radical, e.g., a carboxyl group and a sulfo group, may be introduced into a hydrophilic colloid in the form of an alkaline aqueous solution. Silver halides which can be used in photographic emulsion layers of the light-sensitive material may be any of silver chloride, silver bromide, silver chlorobromide, silver iodobromide, silver chloroiodobromide, and silver iodobromide. The silver halide grains of the photographic emulsions may have a regular crystal form, such as a cubic form, a tetradecahedral form, and an octahedral form; an irregular crystal form, such as a spherical form and a plate form; a crystal form having a crystal defect, such as a twinning plane; or a composite crystal form thereof. The silver halide grains can have a wide range of grain sizes, including fine grains of about 0.2 µm or less to large grains having a projected area diameter of 10 µm. The silver halide emulsion may be a mono-dispersed emulsion or a poly-dispersed emulsion. Silver halide photographic emulsions which can be used in the present invention can be prepared by the processes described, e.g., in Research Disclosure , No. 17643 (Dec., 1978), pp. 22-23, "I. Emulsion Preparation and Types", and ibid , No. 18716 (Nov., 1979). Mono-dispersed emulsions described in US-A-3,574,628 and US-A-3,655,394 and GB-B-1,413,748 can be advantageously used as well. Tabular silver halide grains having an aspect ratio of about 5 or more are also useful. Suitable tabular grains can easily be prepared by the processes described, e.g., in Gutoff, Photographic Science and Engineering , Vol. 14, pp. 248-257 (1970), US-A-4,434,226, 4,414,310, 4,433,048, and 4,439,520, and GB-B-2,112,157. The silver halide grains may be homogeneous grains having a uniform crystal structure throughout the individual grains or heterogeneous grains including those in which the inside and the outer shell have different halogen compositions, those in which the halogen composition differs within layers thereof, and those having a silver halide of a different halogen composition epitaxially grown. Silver halide grains fused with compounds other than silver halides, e.g., silver rhodanide or lead oxide may also be used. A mixture comprising grains of various crystal forms can also be used. The silver halide emulsions are usually subjected to physical ripening, chemical ripening, and spectral sensitization. Additives which can be used in these steps are described in Research Disclosure , Nos. 17643 and 18716 as listed below. Other known photographic additives which can be used in the present invention are also described therein as listed below. Additive RD 17643 RD 18716 1.

These couplers can be incorporated into the photographic emulsion layers using various known dispersion methods. Examples of high-boiling point organic solvents which can be used in a oil-in-water dispersion method are described, e.g., in US-A-2,322,027. A method of using a polymer as a medium for dispersing couplers as described in JP-B-48-30494, US-A-3,619,195, DE-B-1,957,467, and JP-B-51-39835 can also be employed. With respect to the latex dispersion method, the steps involved, the effects, and specific examples of impregnatable lattices are described in US-A-4,199,363 and DE-A-2,541,274 and 2,541,230. Antistatic agents which can be suitably used in the light-sensitive material include fluorine-containing surface active agents or polymers as described in JP-A-62-109044 and JP-A-62-215272, nonionic surface active agents as described in JP-A-60-76742, JP-A-60-80846, JP-A-60-80848, JP-A-60-80839, JP-A-60-76741, JP-A-58-208743, and JP-A-62-172343, JP-A-62-173459 and JP-A-62-215272, and electrically conductive polymers or latices (including nonionic, anionic, cationic, and amphoteric) as described in JP-A-57-204540 and JP-A-62-215272. Preferred of them are the cationic latex polymers described in JP-B-44-16238, JP-A-50-54672, JP-A-54-1398, US-A-4,118,231 and 3,988,158, JP-B-58-56858, JP-A-55-65950, JP-A-55-67746. Examples of suitable inorganic antistatic agents include halides, nitrates, perchlorates, sulfates, acetates, phosphates or thiocyanates of ammonium, alkali metals or alkaline earth metals and, in addition, electrically conductive tin oxide or zinc oxide, or complex oxides thereof (metal oxides doped with antimony, etc.). Further, various charge transfer complexes, π-conjugated high polymers and doped products thereof, organic metal compounds, and interlayer compounds are also useful as anti static agents. Such compounds include TCNO(tetracyanoquinodimethane)/TTF(tetrathiofulvalene), polyacetylene, and polypyrrole. Examples of these antistatic agents are described in Morita, et al., Kagaku to Kogyo , Vol. 59 (3), pp. 103-111 (1985), ibid , Vol. 59 (4), pp. 146-152 (1985). Fluorine-containing compounds or silicon-containing compounds can be used as an antistatic agent, an adhesion preventing agent, a slipping agent, or a coating aid to improve various characteristics of the light-sensitive material. These compounds may be either low-molecular weight compounds or high-molecular weight compounds. A choice is made depending on the end use from known fluorine-containing compounds and silicon-containing compounds including, for example, the compounds described in JP-A-62-215272. Polymers can also be used in the present invention. Polymers may be used in the form of a polymer latex. In the present invention, polymers have the following functions: a) When used in gelatin, to increase dimensional stability and softness, and to decrease frictional resistance; or to diminish the tendency of a dispersed material to agglomerate due to presence of a metal salt. b) To increase electrical conductivity for a reduction in the quantity of static electricity. c) To accelerate drying. d) To prevent destruction of a color forming layer. e) To increase the wet strength of a photographic paper. f) To increase covering and protective power of dispersed materials. g) To accelerate development. h) To reduce high temperature fog. i) To increase color density. j) To reduce distortion desensitization. Disclosures of these functions of polymers are found, e.g., in JP-A-62-215272. These and other known polymers can be used depending on the end use of a light-sensitive material. In the present invention, other various known additives or modifiers for improving the coating characteristics and film properties, such as surface active agents, slipping agents, thickeners, antistatic agents, matting agents, and the like, can be employed. Any known additives, including those described in JP-A-62-215272, can be used depending on the end use to achieve these effects. Examples of supports which can be appropriately used in the present invention are described, e.g., in Research Disclosure , No. 17632, p. 28, and ibid , No. 18716, pp. 647 (right column) to 648 (left column). The method of processing according to the present invention is applicable to various color light-sensitive materials. It is also applicable to color light-sensitive materials described in JP-A-64-59351 and JP-A-63-129341. In light-sensitive materials for photography, hydrophilic colloidal layers on the side having the emulsion layers preferably have a total film thickness of not more than 28 pm and a rate of swell T 1/2 of not more than 30 seconds. The terminology "total film thickness" as used herein means the film thickness as measured after conditioning at 25°C and a relative humidity of 55% for 2 days. The terminology "rate of swell T 1/2 " means the time required for a color light-sensitive material to swell to 1/2 the saturated swollen thickness, the saturated swollen thickness being defined to be 90% of the maximum swollen thickness which is reached when the color light-sensitive material is swollen with a color developing solution at 30°C for 3 minutes and 15 seconds. The rate of swell can be determined by methods known in the art using, for example, a swellometer of the type described in A. Green et al., Photographic Science and Engineering , Vol. 19, No. 2, pp. 124-129. The rate of swell T 1/2 can be controlled by adding a hardening agent for a gelatin binder or by varying the aging conditions of the coating compositions. Further, the light-sensitive material preferably has a degree of swelling of from 150 to 400%. The terminology "degree of swelling" as used herein means the value obtained from the maximum swollen film thickness as defined above according to formula: (maximum swollen film thickness - film thickness)/film thickness. The present invention is illustrated in greater detail with reference to the following Examples, but it should be understood that the present invention is not deemed to be limited thereto. All percents, parts, and ratios are by weight unless otherwise indicated.

A part of the samples was exposed to light at an adjusted exposure amount so as to provide a grey density of 2.0. The unexposed samples and the exposed samples were processed according to the following procedures using processing solutions having the following compositions and a processing machine for motion picture film (running test). The ratio of the unexposed sample and the exposed sample was 1:1. Samples evaluated as hereinafter described were processed after the total amount of the color developer replenisher reached 3 times the volume of the tank of the start liquor.

Diammonium Ethylenediaminetetraacetate 1.7 g Preservative see Table 1 Ammonium Thiosulfate (700 g/ℓ) 340.0 mℓ Water to make 1.0 ℓ pH 7.0 Washing Water: The start liquor and the replenisher had the same composition. Tap water was passed through a mixed bed column packed with an H type strongly acidic cation-exchange resin ("Amberlite IR-120B" produced by Rohm & Haas Co.) and an OH type strongly basic anion-exchange resin ("Amberlite IRA-400" produced by Rohm & Haas) to decrease the amount of calcium and magnesium ions, each to 3 mg/ℓ or less. To the deionized water were added 20 mg/ℓ of dichlorinated sodium isocyanurate and 150 mg/ℓ of sodium sulfate. The resulting washing water had a pH between 6.5 and 7.5. Stabilizing Bath: The start liquor and the replenisher had the same composition. Formaldehyde (37 wt% aq. soln.) 1.2 mℓ Surface Active Agent (C 10 H 21 -O(CH 2 CH 2 O) 10 H) 0.4 g Ethylene Glycol 1.0 g Water to make 1.0 ℓ pH 5.0-7.0 Then, the same running test as described above was conducted, except for carrying out bleaching at 38°C for 40 seconds using Bleaching Bath (B) shown below in place of Bleaching Bath (A) at a rate of replenishment of 25 mℓ/m. Each of the processed samples obtained from samples which had been uniformly exposed to light to provide a grey density of 2.0 was analyzed using a fluorescent X-ray method to determine the amount of residual silver. On the other hand, each of the processed samples obtained from the unexposed samples was stored under a high temperature and high humidity condition (60°C, 70% RH) for 35 days to observe stain (the increase in minimum density of the yellow or magenta image). The stain was expressed in terms of a difference in minimum density (D min ) between the yellow or magenta image before storage and the yellow or magenta image after storage ( Δ D B or Δ D G , respectively). Δ D B = (D min of yellow image after storage) - (D min of yellow image before storage) Δ D g = (D min of magenta image before storage) - (D min of magenta image after storage) Further, the fixing bath, washing water, and stabilizing bath were examined to determine whether or not any precipitate was formed. The results of these measurements and evaluations are shown in Table 2 below. As can be seen from the results in Tables 1 and 2 above, when the compound used according to the present invention is used in a fixing bath, the fixing bath and the succeeding processing solutions have improved stability, and no precipitates are formed. Further, as compared with known aldehyde bisulfite addition compounds described, e.g., in JP-A-48-42733, the compound used in the present invention proves effective to improve image preservability. The compound used in the present invention improves the stability of a processing solution with time as compared with the acetaldehyde bisulfite addition compound. This seems to be because the amount of acetaldehyde is decreased due to oxidative deterioration or evaporation loss, whereas the compound used in the present invention is not so influenced and shows excellent stability of itself. It is also seen that use of a 2-equivalent magenta coupler (ExM-5) provides an improvement in image preservability. The reason why the washing bath and the stabilizing bath also show improved stability as well as the fixing bath to which the compound used in the present invention is added is believed due to the carry-over from the fixing bath into the succeeding baths. The compound used in the present invention also surpassed the compounds proposed in JP-A-1-267540 in improving stability of processing solutions with time (i.e., reduction in tendency to form precipitates). EXAMPLE 2 A running test was carried out in the same manner as in Run No. 1 of Example 1, except for changing the preservative of the fixing bath as shown in Table 3 below. The formation of precipitates in each processing solution of fixing, washing, and stabilizing and the increase of coloring of the fixing bath were evaluated. The results obtained are shown in Table 3 below. As is apparent from the results in Table 3 above, when the preservative of the present invention is used as a preservative in a fixing bath, the fixing bath and the succeeding processing solutions exhibit improved stability with time as compared with conventional preservatives, i.e., sodium sulfite or an acetaldehyde bisulfite addition compound described, e.g., in JP-A-48-42733. The compound used in the present invention also proved to be advantageous in that precipitation in the processing solutions was reduced and the fixing bath underwent no coloration as compared with the carbonyl bisulfite addition compound described in JP-A-1-267540. EXAMPLE 3 The following layers were coated on a paper support having polyethylene laminated on both sides thereof and having colloidal silica and colloidal alumina coated on the back side thereof. The resulting multi-layer color paper was designated Sample 301. The coating compositions were prepared as follows. Preparation of First Layer Coating Composition: To a mixture of 19.1 g of a yellow coupler (ExY), 4.4 g of a dye image stabilizer (Cpd-1), and 0.7 g of a dye image stabilizer (Cpd-7) were added 27.2 mℓ of ethyl acetate and 8.2 g of a solvent (Solv-3) to form a solution. The resulting solution was emulsified and dispersed in 185 mℓ of a 10% gelatin aqueous solution containing 8 mℓ of 10% sodium dodecylbenzenesulfonate. Separately, a cubic silver chlorobromide emulsion having a mean grain size of 0.88 µm and a coefficient of variation of size distribution of 0.08 and locally containing 0.2 mol% of silver bromide on the grain surface was prepared, and each of blue-sensitive sensitizing dyes shown below was added thereto in an amount of 2.0 x 10 -4 mol/mol-Ag. The thus spectrally sensitized emulsion was then subjected to sulfur sensitization. The above-prepared coupler dispersion and the finished emulsion were mixed to prepare a First Layer coating composition having the composition shown below. Coating compositions for the Second to Seventh Layers were also prepared in the same manner as the First Layer coating composition. To each coating composition, 1-oxy-3,5-dichloro-s-triazine sodium salt was added as a gelatin hardening agent. The spectral sensitizing dyes used in each light-sensitive layer and their amounts are shown below. To the coating composition for the red-sensitive emulsion layer was further added a compound shown below in an amount of 2.6 x 10 -3 mol/mol-AgX. To each of the coating compositions for the blue-, green- and red-sensitive emulsion layers was further added 1-(5-methylureidophenyl)-5-mercaptotetrazole in an amount of 8.5 x 10 -5 mol, 7.7 x 10 -4 mol, and 2.5 x 10 -4 mol, respectively, per mol of AgX. For the purpose of preventing irradiation, the following dyes were added to the emulsion layers. The layer structure of the multi-layer color paper is shown below. The amount of silver halide coated is shown as silver coverage (g/m 2 ). Support: Polyethylene-laminated paper, the polyethylene layer on the side to be coated with the First Layer contained a white pigment (TiO 2 ) and a bluish dye (ultramarine). The couplers and other photographic additives used above are shown below. Solvent (Solv-3): O=P(O-C 9 H 19 (iso)) 3 Sample 302 was prepared in the same manner as Sample 301, except for using the following layer as the Third Layer (green-sensitive emulsion layer). Samples 301 and 302 were cut to a fixed size and fabricated. After imagewise exposure, the samples were processed according to the following procedure using processing solutions having the following compositions using a paper processor until the total amount of the color developer replenisher reached 3 times the tank volume of the start liquor (running test). Then, a pair of samples were processed in the same manner, one pair being unexposed, and the other pair being exposed to light at an adjusted exposure amount so as to provide a grey density of 2.0. The bleach-fixing bath was replenished with a bleach-fixing bath replenisher and the rinsing bath (1) (121 mℓ). The contact area of each processing solution with air was 500 cm 2 .

Ion-exchange water having calcium and magnesium levels each reduced to 3 ppm or less. Then, the same procedure was repeated, except for replacing the bleaching agent of the bleach-fixing bath, ammonium(ethylenediaminetetraacetato)iron (III), with an equimolar amount of ammonium (1,3-diaminopropanetetraacetato)iron (III). Each of the processed samples obtained from those which had been uniformly exposed to light to provide a grey density of 2.0 was analyzed using a fluorescent X-ray method to determine the amount of residual silver. Further, the bleach-fixing bath and washing water were examined whether or not any precipitate was formed. The results of these measurements and evaluations are shown in Table 4 below. As shown by the results in Table 4 above, the compounds used according to the present invention, when used as a preservative in a bleach-fixing bath, improve the stability of the bleach-fixing bath and the succeeding processing solution as compared with known preservatives, such as ammonium sulfite and acetaldehyde (described in JP-A-48-42733). When, in particular, a (1,3-propanediaminetetraacetato)iron (III) complex salt is used as a bleaching agent, not only the bleach-fixing bath but also the succeeding processing solutions undergo serious deterioration due to poor stability with time. It can be seen that the use of the compounds used according to the present invention as a preservative results in a marked improvement in stability of these processing solutions, thus achieving rapid desilvering consistently with improved stability of processing solutions. The compounds used in the present invention also proved advantageous in that precipitation in the processing solutions is reduced as compared with the use of the carbonyl bisulfite addition compound described in JP-A-1-267540. It is believed that the performance of carbonyl compounds as a preservative depends on its readiness to form an addition compound with bisulfite ion. The compounds used in the present invention appear to be superior to salicylaldehyde in this respect and, therefore, achieve stabilization of the washing water as demonstrated above. Further, the compounds used in the present invention have the advantage of preventing coloration of the bleach-fixing bath. Considering that coloration of the processing solution is a phenomenon characteristic of aldehydes having a hydroxyl group, a hydroxyl group seems to undergo a chemical reaction with a component carried over from the developing solution to form a coloring component. Thus, the present invention is effective to improve the stability of processing solutions. Also, in case of Sample 302, the same results as in Sample 301 can be obtained. EXAMPLE 4 Samples 401 to 410 were prepared in the same manner as Sample 301 of Example 3, except for replacing the cyan coupler ExC used in the Fifth Layer of Sample 301 with each of Cyan Couplers C-i to C-viii and Cyan Couplers C-a and C-b shown below. Each of Samples 401 to 410 was cut to a width of 35 mm and fabricated, and the unexposed sample was continuously processed in the same manner as in Run Nos. 3 or 7 of Example 3. The processed sample was stored under high temperature and high humidity conditions (60°C, 70% RH) for 35 days, and stain (the increase in minimum density of the yellow image) was evaluated.

EXAMPLE 5 The following First to Fourteenth Layers were coated on a 100 µm thick paper support having polyethylene laminated on both sides thereof, and the following Fifteenth to Sixteenth Layers were coated on the opposite side of the support. The polyethylene layer on the First Layer side of the support contained titanium oxide as a white pigment and a trace amount of ultramarine as a bluish dye. The chromaticity of the surface of the support was 88.0, -0.20, and -0.75 according to an L*a*b* colorimetric system. The resulting sample was designated Sample 501. The silver bromide emulsions used in the light-sensitive emulsion layers except for the Fourteenth Layer were prepared according to the following process. A potassium bromide aqueous solution and a silver nitrate aqueous solution were simultaneously added to a gelatin aqueous solution at 75°C over a 15 minute period under vigorous stirring to obtain an octahedral silver bromide emulsion having a mean grain size of 0.40 µm. To the emulsion were added 0.3 g of 3,4-dimethyl-1,3-thiazolin-2-thione, 6 mg of sodium thiosulfate, and 7 mg of chloroauric acid tetrahydrate each per mol of silver, and the emulsion was heated at 75°C for 80 minutes for chemical sensitization. The thus obtained silver bromide grains were allowed to grow as a core in the same precipitation-inducing environment as described above to ultimately obtain an octahedral mono-dispersed core/shell silver bromide emulsion having a mean grain size of 0.7 µm and a coefficient of size variation of about 10%. To the emulsion were added 1.5 mg of sodium thiosulfate and 1.5 mg of chloroauric acid tetrahydrate each per mol of silver, followed by heating at 60°C for 60 minutes for chemical sensitization. An internal latent image type silver halide emulsion was thus obtained. Further, the mixing ratio of each components is by weight. In the Fourteenth Layer, a Lippmann emulsion which had not been subjected to surface chemical sensitization was used.

Then, an unexposed sample and a sample uniformly exposed to light at an exposure amount adjusted to provide a grey density of 2.0 were processed for evaluation. Processing Step Temp. Time Rate of Replenishment Tank Volume (°C) (sec) (mℓ/m 2 ) (ℓ) Color Development 38 135 300 15 Bleach-Fixing 33 40 300 3 Washing (1) 33 40 - 3 Washing (2) 33 40 320 3 Drying 80 30 - - The washing bath was replenished with a countercurrent system, in which bath (2) was replenished while introducing the overflow therefrom into bath (1). The carry-over from the bleach-fixing bath into the washing bath (1) was 35 mℓ/m 2 , and the amount of the washing water replenisher was 9.1 times the carry-over of the bleach-fixing bath. The contact area of each processing solution with air was 75 cm 2 . The processing solutions used had the following compositions. Bleach-Fixing Bath: (The start liquor and the replenisher had the same composition.) Disodium Ethylenediaminetetraacetate Dihydrate 4.0 g Ammonium (ethylenediaminetetraacetato)iron (III) Dihydrate 70.0 g Ammonium Thiosulfate (700 g/ℓ) 180 mℓ Sodium p-Toluenesulfinate 20.0 g Preservative (see Table 6) 0.3 mol Ammonium Sulfite 0.3 mol 5-Mercapto-1,3,4-triazole 0.5 g Ammonium Nitrate 10.0 g Water to make 1000 mℓ pH (25°C) 6.20 Washing Water: (The start liquor and the replenisher had the same composition.) Tap water was passed through a mixed bed column packed with an H type strongly acidic cation-exchange resin ('Amberlite IR-120B", produced by Rohm & Haas) and an OH type anion-exchange resin ("Amberlite IRA-400" produced by Rohm & Haas) to decrease the calcium and magnesium each to 3 mg/ℓ or less. To the deionized water were added 20 mg/ℓ of dichlorinated sodium isocyanurate and 1.5 g/ℓ of sodium nitrate. The resulting washing water had a pH between 6.5 and 7.5. The processed sample obtained from the exposed sample was analyzed using a fluorescent X-ray method to determine the amount of residual silver. The density of the cyan image was measured, and the sample was soaked in the bleaching bath used in Run No. 7 of Example 1 for 30 minutes, washed with water for 1 minute and dried. The color density of the thus treated cyan image was measured to evaluate color restoration insufficiency (ΔD R = (cyan density after re-bleaching) - (cyan density before re-bleaching)). Further, the formation of a precipitate in the bleach-fixing bath and the washing water was determined. The results obtained are shown in Table 6 below. As can be seen from the results in Table 6 above where processing is carried out with an automatic developing machine having a contact area between each processing solution and air as small as 75 cm 2 , when a bleach-fixing bath containing ammonium sulfite conventionally used as a preservative is employed, satisfactory color restoration cannot be achieved, and the developed cyan dye becomes a leuco dye causing a reduction in color density. The color restoration insufficiency can be eliminated using the compound according to the present invention. This effect was particularly marked in using Compounds A'-1, A'-2, A'-3, A'-9, and A'-10. Further, the compounds used in the present invention proved to have the advantage of preventing coloration of the bleach-fixing bath as compared with a conventionally used carbonyl bisulfite addition compound (described in JP-A-1-267540). EXAMPLE 6 The procedures of Example 1 were repeated, except for altering the preservative in the fixing bath as shown in Table 9 below. The formation of a precipitate in the fixing bath, washing water and stabilizing bath and coloration of these processing solutions were determined. The results obtained are shown in Table 9 below. The compounds E-1, E-2, F-1, G-2 and E-17 are represented by the following formulae : As can be seen from the results in Table 9, as compared with the single use of each of the compounds used according to the present invention, the combined use of these compounds results in an improvement in the stability of the fixing bath and the succeeding processing solutions, and no precipitate is formed. This effect is particularly marked in Bleaching Bath (A). This combined use also results in an improvement in desilvering performance and image preservability. These effects can also be produced when the compounds used in the present invention are separately used in a fixing bath and washing water. EXAMPLE 7 A sample was prepared in the same manner as in Example 5, except for replacing Cpd-26 and ExM-3 with Cpd-26' and ExM-3' shown below, respectively. The resulting sample was processed in the same manner as in Example 5, except that Components (I) and (II) shown in Table 11 below were used as a preservative in the bleach-fixing bath. The results obtained are shown in Table 11 below. As is shown by the results in Table 11, where processing is carried out using an automatic developing machine having a contact area between each processing solution and air as small as 75 cm 2 , with a bleach-fixing bath containing ammonium sulfite conventionally used as a preservative, satisfactory color restoration cannot be achieved, and the developed cyan dye becomes a leuco dye reducing the color density. This color restoration insufficiency can be eliminated by using a combination of the compounds used according to the present invention as compared with the single use of these compounds. Further, the combined use is effective to markedly prevent formation of a precipitate in the bleach-fixing bath or washing water. As demonstrated above, the stability of processing solutions can be improved and stain formation can be suppressed by incorporating Component (I) and Component (II) into a processing solution of at least one of the processing steps involved.
