Description

FIELD OF THE INVENTION

The present invention relates to a method for processing (hereinafter referred to as "processing") an exposed silver halide color photographic material (hereinafter referred to as "color light-sensitive material"). More particularly, the present invention relates to a method for rapidly processing a color light-sensitive material having an improved desilvering capability.

BACKGROUND OF THE INVENTION

In general, the processing of a color light-sensitive material essentially consists of a color developing step and a desilvering step. In the color developing step, silver halide which has been exposed to light is reduced by a color developing agent to produce silver. At the same time, the color developing agent which as been oxidized reacts with a color forming agent (coupler) to provide color images. The silver thus produced is oxidized by a bleaching agent in a subsequent desilvering step and then acted on by a fixing agent to become a soluble silver complex which is then dissolved and removed.

The practical developing process comprises various auxiliary steps besides the above described basic steps in order to maintain photographic and physical qualities of the images or improve the preservability of the images. Examples of such auxiliary steps include a hardening step, a stopping step, an image stabilizing step, and a washing step.

In recent years, the industry has seen a growing demand for rapid processing, i.e., shorter time required for processing, especially at the desilvering step, which accounts for the majority of the total processing time.

As bleaching agents there have generally been known red prussiate, bichromate, ferric chloride, ferric aminopolycarboxylate complex, and persulfate.

However, red prussiate and bichromate have a disadvantage in that these salts can give cyanide or hexavalent chromium pollution and thus require a special treatment facility. Ferric chloride has a disadvantage in that it produces iron hydroxide or stain at the subsequent washing process, thereby impeding the practical use thereof. Persulfate has a disadvantage in that it requires a remarkably long period of time to finish bleaching due to its very weak bleaching effect.

Ferric aminopolycarboxylate complex salts (particularly ferric ethylenediaminetetraacetate complex salts) have less pollution problems and no storage problem as for persulfate and are therefore most widely put into practical use as bleaching agents.

However, it cannot always be said that ferric aminopolycarboxylate has a sufficient bleaching capability.

As a means of expediting the desilvering process there has heretofore been known a combined blixing solution containing ferric aminopolycarboxylate and thiosulfate as described in West German Patent No. 866,605. However, such a combined blixing solution has a disadvantage in that the coexistence of a ferric aminopolycarboxylate complex, which has a weak oxidizing power (bleaching power), with a thiosulfate having a reducing power provides a much weaker bleaching power, making it extremely difficult to fully desilver a color light-sensitive material for photography having a high sensitivity and a high silver content, in particular.

Furthermore, if the processing is conducted with a reduced amount of replenisher of the processing solutions (i.e., bleaching solution, blixing solution and/or fixing solution) to be used in the desilvering of the silver halide color photographic material, in order to protect the environment, save costs, and simplify the processing, silver halide eluted from the light-sensitive material is accumulated in a high concentration as a silver complex in these processing solutions. This causes more precipitate to be produced or reduces the activity of the processing solutions, further weakening the bleaching power thereof. Thus, it was found that a reduction in the amount of replenisher of the processing solution to be used in the desilvering process causes many difficulties.

On the other hand, as a method of improving the bleaching power there has been proposed a method which comprises adding various bleaching accelerators to the bleaching bath, blixing bath, or previous bath (prebath) thereof. Examples of such bleaching accelerators include various mercapto compounds as described in U.S. Pat. No. 3,893,858, British Patent No. 1,138,842, and Japanese Patent Application (OPI) No. 141623/78 (the term "OPI" as used herein refers to a "published unexamined Japanese patent application"), compounds containing disulfide bonds as described in Japanese Patent Application (OPI) No. 95630/78, thiazolidine derivatives as described in Japanese Patent Publication No. 9854/78, isothiourea derivatives as described in Japanese Patent Application (OPI) No. 94927/78, thiourea derivatives as described in Japanese Patent Application (OPI) No. 8506/70, and Japanese Patent Publication No. 26586/74, thioamide compounds as described in Japanese Patent Publication No. 42349/74, dithiocarbamate as described in Japanese Patent Application (OPI) No. 26506/80, and arylenediamine compounds as described in U.S. Pat. No. 4,552,834.

It is certain that among these bleaching agents, those showing a bleach accelerating effect are present. However, those bleaching accelerators leave much to be desired in practicality. For example, some bleaching accelerators are expensive or have insufficient stability in a bath having a bleaching capability.

Furthermore, if the light-sensitive material is processed in a bleaching bath, blixing bath, or prebath thereof containing these various bleaching accelerators, and these bleaching accelerators are compounds containing mercapto groups, these mercapto compounds produce a sparingly soluble silver salt with unexposed silver halide or silver halide produced by the bleaching reaction in the emulsion layer of the light-sensitive material. Such a sparingly soluble silver salt cannot be solubilized by a fixing agent, possibly causing poor fixation.

Thus, the inventors have found that the reduction of the amount of replenisher of the processing solution to be used in the desilvering process causes more silver ions to be accumulated in the desilvering bath, and these silver ions form a sparingly soluble silver salt with the mercapto compound, further reducing the bleach accelerating effect to an insufficient level. The inventors have also found that the presence of iodide ions in the desilvering solution promotes such a reaction.

Furthermore, the above described mercapto compounds include those which react with sulfite ions in the processing solution to undergo decomposition (Sulfur Dioxide, L. C. Schroeter, Pergamon Press (1966)). The ordinary blixing solution comprising a thiosulfate as a fixing agent contains a sulfite in combination. Therefore, such a mercapto compound is susceptible to decomposition in the blixing solution.

As described above, the use of such a mercapto bleaching accelerator in the processing solution or its prebath to be used in the desilvering process has many limitations.

On the other hand, there has been known a process which comprises processing a light-sensitive material containing such a mercapto compound or its precursor as described in Japanese Patent Application (OPI) Nos. 135834/87 and 80649/87. However, if such a mercapto compound is contained in a light-sensitive material, it may greatly affect the photographic properties, and silver halide contained in unexposed portions in the light-sensitive material and such a mercapto compound form a sparingly soluble salt. Thus, this approach leaves much to be desired.

SUMMARY OF THE INVENTION

One object of the present invention is to provide a method for processing a silver halide color photographic material which enables rapid desilvering even with a reduced amount of replenisher of a desilvering solution.

Another object of the present invention is to provide a method for processing a color light-sensitive material which is excellent in the blixing capability, particularly in the fixing capability.

A further object of the present invention is to provide a rapid desilvering step which enables the stabilization of the blixing solution.

Still another object of the present invention is to provide a rapid desilvering step which causes fewer pollution problems.

Still a further object of the present invention is to provide a rapid desilvering step which cost less and is more practical than those currently available.

These objects of the present invention are accomplished by providing a method for processing a silver halide color photographic material which comprises imagewise exposing a silver halide color photographic light-sensitive material to light, color-developing the light-sensitive material, and then desilvering the light-sensitive material, wherein: (a) the silver halide color photographic light-sensitive material contains a compound which reacts with an oxidation product of an aromatic primary amine color developing agent to form a bleaching accelerator, (b) the desilvering step is conducted with at least a processing solution containing a ferric complex salt of an organic acid, and (c) the total amount of replenisher of the processing solution to be used in the desilvering step satisfies either the following conditions (i) and (ii):

(i) the total amount of replenisher is 1,000 ml or less per m² of the light-sensitive material if the coated amount of silver per m² of the light-sensitive material is 2.0 or more;

DETAILED DESCRIPTION OF THE INVENTION

When a compound which reacts with an oxidation product of an aromatic primary amine color developing agent to release a bleaching accelerator (hereinafter referred to as "bleaching accelerator-releasing compound") is contained in a light-sensitive material in accordance with the present invention, the result is surprising in that very rapid desilvering can be made to occur even under the above described conditions (i) or (ii) wherein a very small amount of the processing solution is replenished.

Further, the present inventors found that these objects of the present invention are accomplished by a method for the processing of a silver halide color photographic material which comprises imagewise exposing the silver halide color photographic material to light, color-developing the silver halide color photographic material and then desilvering the light-sensitive material with a processing solution having a blixing capability, wherein the silver halide color photographic material contains a compound which reacts with an oxidation product of an aromatic primary amine color developing agent to release a bleaching accelerator, and the processing solution having a blixing capability contains preferably a ferric aminopolycarboxylate complex salt having a molecular weight of 300 or more in the form of a free acid.

On the other hand, Research Disclosure, RD Nos. 24242 and 11449, and Japanese Patent Application (OPI) No. 201247/86 describe methods using bleaching accelerator-releasing couplers. In the above described processed method, however, the light-sensitive material is bleached and then fixed after being color-developed. Since such a bleaching accelerator is stable in a bleaching solution so long as the replenished amount of the bleaching solution is in the normal range, the effect of the bleaching accelerator in the case where such a bleaching accelerator-releasing compound is used is similar to that of the case where such a bleaching accelerator is incorporated in the bleaching solution. Thus, the above described method provides no special effects. Furthermore, there has been no teaching that the use of a high molecular weight ferric aminopolycarboxylate complex salt providing a stable blixing solution as described herein can further eliminate the deterioration in the blixing capability, particularly in the fixing capability.

Another method has been proposed which comprises washing a light-sensitive material containing such a bleaching accelerator-releasing compound after being color-developed, and then subjecting the light-sensitive material to blixing. However, it was found that this method has a disadvantage in that the bleaching accelerator is washed out from the light-sensitive material in the washing bath, thereby impeding the expected bleach accelerating effect.

When a light-sensitive material containing the present bleaching accelerator-releasing coupler is color-developed, a bleaching accelerator is released in the vicinity of metal produced by development (hereinafter referred to as "developed silver") in an amount proportional to the amount of developed silver. Since such a bleaching accelerator is transferred to the subsequent desilvering process while being adsorbed by metal, it presumably prevents the reaction with silver ions and/or iodide compound ions which produces precipitates. Therefore, a light-sensitive material containing the present bleaching accelerator-releasing coupler which has been color-developed is preferably immediately processed with a processing solution having a blixing capability or a processing solution having a fixing capability and then with a processing solution having a blixing capability. If such a light-sensitive material which has been color-developed is washed with water, and then processed with a processing solution having a blixing capability, the bleach accelerating effect is disadvantageously eliminated. In order to prevent such an elimination of the bleach accelerating effect when the light-sensitive material is not immediately processed with a processing solution having a blixing capability or a processing solution having a fixing capability and then with a processing solution having a blixing capability, the light-sensitive material which has been color-developed is preferably immediately processed with a processing solution having a salt concentration of 2×10^-3 mol/l or more, and then processed with a processing solution having a blixing capability.

The condition (i) wherein the coated amount of silver per m² of the silver halide photographic material is 2.0 g or more (particularly from 2.0 to 20 g) can be applied to color negative film, color reversal film, color negative film for motion picture, color internegative film, etc. In the present invention, the total amount of replenisher of the processing solution to be used in the desilvering of such light-sensitive materials can be remarkably reduced to 1,000 ml or less, and preferably from 100 to 700 ml, per m² of the light-sensitive material.

The condition (ii) wherein the coated amount of silver per m² of the silver halide photographic material is less than 2.0 g (particularly from 0.3 to less than 2.0 g) can be applied to color paper, reversal color paper, automatic positive color paper, color positive paper for motion picture, etc. In the present invention, the total amount of replenisher of the processing solution to be used in the desilvering of such light-sensitive materials can be remarkably reduced to 400 ml or less, preferably 300 ml or less, and particularly preferably from 50 to 300 ml, per m² of the light-sensitive material.

The desilvering step as mentioned herein normally consists of one or a combination of two or three of processing with a processing solution having a bleaching capability (bleaching), processing with a processing solution having a blixing capability (blixing), and processing with a processing solution having a fixing capability (fixing).

Examples of such a combination include the following:

(1) Bleaching-Fixing

(2) Bleaching-Blixing

(3) Blixing

(4) Fixing-Blixing

(5) Bleaching-Blixing-Fixing

(6) Blixing-Bleaching

(7) Blixing-Fixing

In view of the rapid processing, preferred among these combinations is the combination (2) as described in Japanese Patent Application (OPI) No. 143755/86. Also, the combination (3) having less steps may be preferably used for the purpose of simplifying the processing.

In the present invention, the total amount of replenisher of the processing solution to be used in the desilvering means the replenished amount of the processing solution if the desilvering process consists of only one desilvering process as in the combination (3) or the total of the replenished amount of two or more desilvering solutions if the desilvering process consists of two or more desilvering steps as in the combinations (1), (2), (4), (5), (6) and (7).

The method for processing a silver halide color photographic material containing a compound which releases a bleaching accelerator (i.e., a bleaching accelerator-releasing compound) with a processing solution containing a specific ferric complex salt and having a blixing capability in accordance with the present invention enables an improvement in the solution stability and rapid processing with an excellent blixing capability. It was also found that the deterioration in color restoration of cyan images which becomes a remarkable with increasing processing speed can be eliminated by incorporating at least one cyan dye-forming coupler represented by the formulae (l-I) or (l-II) in the light-sensitive material. More surprisingly, such an improvement in color restoration becomes more remarkable when a ferric aminopolycarboxylate complex salt is used as a bleaching agent than when a ferric ethylenediaminetetraacetate is used. Such an improvement in color restoration enables a further rapid blixing processing. Furthermore, the combined use of the cyan dye-forming coupler enables an improvement in image stability. ##STR63## wherein R₁₀₁ and R₁₀₂ each independently represents an aliphatic group, an aryl group or a heterocyclic group; R₁₀₃ represents a hydrogen atom, a halogen atom, an aliphatic group having from 5 to 25 carbon atoms, an aryl group having from 5 to 25 carbon atoms, an acylamino group, or nonmetallic atomic groups which form a 5- or 6- membered nitrogen-containing ring together with R₁₀₂ ; A₁₀ represents a hydrogen atom or coupling-releasable group; and n₁ represents an integer of 0 or 1. ##STR64## wherein R₁₁₁ represents --CONR₁₁₅ R₁₁₆, --NHCOR₁₁₅, --NHCOOR₁₁₇, --NHSO₂ R₁₁₇, --NHCONR₁₁₅ R₁₁₆ or --NHSO₂ NR₁₁₅ R₁₁₆ ; R₁₁₂ represents a group which can be substituted by a naphthol ring; n₁ represents an integer of 0 to 3; R₁₁₃ represents a monovalent organic group; and X₁₀ represents a hydrogen atom or a group which can be released by a coupling reaction with an oxidation product of an aromatic primary amine developing agent, with the provisos that: (a) R₁₁₅ and R₁₁₆ may be the same or different and each independently represents a hydrogen atom, an aliphatic group having from 5 to 25 carbon atoms, an aromatic group having from 5 to 25 carbon atoms, or a heterocyclic group, (b) R₁₁₇ represents an aliphatic group, and aromatic group or a heterocyclic group, (c) when m₁ is a plural number, the plurality of R₁₁₂ may be the same or different or may be connected to each other to form a ring, and (d) R₁₁₂ and R₁₁₃ or R₁₁₃ and X₁₀ may be connected to each other to form a ring.

The present silver halide color photographic material is normally subjected to washing and/or stabilization after being subjected to desilvering such as fixing or blixing.

The amount of water to be used in the washing process can be widely selected depending on the properties (different with components such as coupler) and use of the light-snesitive material, washing water temperature, number of washing tanks (stages), replenishing system of a replenisher (e.g., countercurrent or cocurrent), an other various conditions. In a multistage countercurrent system, the relationship between the number of washing tanks and the amount of water to be used in the washing process can be determined in accordance with a method as described in Journal of the Society of Motion Picture and Television Engineers, Vol. 64, pp. 248 to 253 (May, 1955).

In a multistage countercurrent system as described in the foregoing literature, the amount of water to be used in the washing process can be greatly decreased. However, such a multistage countercurrent system is disadvantageous in that an increase in the time of retention of water in the tanks causes the propagation of bacteria which produce suspended matter that may be attached to the light-sensitive material. In the processing of the present color light-sensitive material, such a problem can be extremely effectively solved by decreasing calcium and magnesium as described in Japanese Patent Application (OPI) No. 288838/87 (corresponding to European Patent Application No. 248459A). Such a problem can also be solved by the use of isothiazolone compounds and thiabendazole as described in Japanese Patent Application (OPI) No. 8542/82, chlorine bactericides such as sodium chlorinated isocyanurate, or bactericides such as benzotriazole as described in Hiroshi Horiguchi, Chemistry of Bactericide and Antifugal Agents, Association of Sanitary Engineering, Sterilization of Microorganism, and Sterizilization and Antifugal Engineering, and Japan Sterilization and Antifungal Association, Dictionary of Bactericide and Antifungal Agents.

The pH value of the washing water to be used in the processing of the present light-sensitive material is in the range of 4 and 9 and preferably 5 to 8. The temperature of washing water and the washing time can be freely determined depending on the properties and application of the light-sensitive material. The optimum washing time is normally between 20 seconds and 10 minutes at a temperature of 15° to 45° C., and preferably between 30 seconds and 5 minutes at a temperature of 25° to 50° C.

Furthermore, the present light-sensitive material may be processed directly with a stabilizing solution rather than by wahsing with water. In such a stabilizing process, known methods as described in Japanese Patent Application (OPI) Nos. 8543/82, 14834/83, 184343/84, 220345/85, 238832/85, 239784/85, 239749/85, 4054/86 and 118749/86 can all be used. Particularly, a stabilizing bath containing 1-hydroxyethylidene-1,1-diphosphonic acid, 5-chloro-2-methyl-4-isothiazoline-3-one, a bismuth compound, an ammonium compound, etc., may be preferably used in the present invention.

The washing process may be followed by a stabilizing process such as a stabilizing bath containing formalin and a surface active agent used as a final processing bath for color light-sensitive material for photography.

The silver halide color photographic material to be used in the present invention is described hereinafter. The emulsion layer in the light-sensitive material may comprise any silver halide selected from silver bromide, silver bromoiodide, silver chlorobromide, silver bromochloroiodide, silver chloride and silver chloroiodide. Particularly preferred among these silver halides is silver bromoiodide. If silver bromoiodide is used, its content of silver iodide is normally in the range of 40 mol % or less, preferably 20 mol % or less, and particularly 10 mol % or less.

The processing method of the present invention is further advantageous in that the bleaching of the light-sensitive material can be effectively accelerated even if the light-sensitive material contains silver iodide, which easily produces precipitation.

The above described particulate silver halide may have a regular crystal structure such as a cube, an octahedron and a tetradecahedron, an irregular crystal structure such as a sphere, a crystal structure having a crystal defect such as twinning plane, or a composite thereof. Alternatively, a mixture of grains of various crystal structure may be used.

the above described silver halide may be in the form of a monodispersed emulsion having a narrow distribution or a polydispersed emulsion having a wide distribution.

The above described emulsion layer may comprise tabular grains having an aspect ratio of 5 or more.

The crystal structure of the present silver halide grains may be uniform, or such that the halide composition varies between the inner portion and the outer portion thereof, or may be a layer. These emulsion grains are disclosed in British Patent No. 1,027,146, U.S. Pat. Nos. 3,505,068, 4,444,877, 4,668,614. Alternatively, silver halides having different compositions may be connected to each other by an epitaxial junction or by any suitable compound other than silver halide such as silver thiocyanate and zinc oxide.

The above described emulsion grains may be those of a surface latent image type in which latent images are formed mainly in the surface portion thereof or those of an internal latent image type in which latent images are formed mainly in the interior thereof. Alternatively, the above described emulsion grains may have the interior thereof chemically sensitized.

A silver halide photographic emulsion which can be used in the present invention can be produced by well known methods, for example, methods as described in Research Disclosure, RD No. 17643, vol. 176, pages 22 and 23, "Emulsion Preparation and Types" (Dec., 1978) and Research Disclosure, RD Np. 18716, Vol. 187, page 648 (Nov., 1979).

The preparation of a silver halide photographic emulsion which can be used in the present invention can be accomplished by using various silver halide solvents such as ammonia, potassium thiocyanate, and thioether and thione as described in U.S. Pat. No. 3,271,157 and Japanese Patent Application (OPI) Nos. 12360/76, 82408/78, 144319/78, 100717/79 and 155828/79.

A typical monodispersed emulsion is an emulsion of silver halide grains having an average grain diameter of more than about 0.1 μm in which the grain diameter of at least 95% by weight thereof falls within ±40% of the average grain diameter. In the present invention, an emulsion of silver halide grains having an average grain diameter of 0.25 to 2 μm in which the grain diameter of at least 95% by weight or number of grains falls within ±20% of the average grain diameter may be used.

In the process of formation or physical ripening of the silver halide grain, cadmium salts, zinc salts, lead salts, thallium salts, iridium salts or complex salts thereof, rhodium salts or complex salts thereof, or iron salts or complex salts thereof may coexist.

The emulsion to be used to be used in the present invention may be normally subjected to phsyical ripening and then to chemical ripening and spectral ripening before use. Examples of additives to be used in such processes are described in Research Disclosure, RD Nos. 17643 (December, 1978) and 18716 (November, 1979). The places where such a description is found are summarized in the table below.

As a spectral sensitizer for the present color photographic light-sensitive material there may be used any suitable spectral sensitizer selected from the above described known compounds. Particularly, exemplary compounds represented by the formula (IV) or (V) described in Japanese Patent Application No. 313598/86 (pp. 90-110) may be preferably used in the present processing process.

Various color couplers can be used in the present invention. Specific examples of such color couplers are described in patents cited in Research Disclosure, RD No. 17643 (VII-C to G). An important dye-forming coupler is a coupler which provides three primaries of subtractive color processes, i.e., yellow, magenta and cyan upon color development. Specific examples of a nondiffusible 4- or 2-equivalent dye-forming coupler of such a type include those described hereinafter besides those described in patents cited in Research Disclosure, RD No. 17643 (VII-C and D).

Typical examples of yellow couplers which may be used in the present invention include known oxygen-releasing type yellow couplers and nitrogen-releasing type yellow couplers, α-Pivaloylacetanilide couplers are excellent in the fastness of color-forming dye, particularly in the fastness to light. On the other hand, α-benzoylacetanilide couplers can provide a high color density.

Examples of magenta couplers which may be used in the present invention include a hydrophobic 5-pyrazolone and pyrazoloazole couplers containing ballast groups. Such 5-pyrazolone couplers preferably contain an arylamino group or an acylamino group as a substituent in the 3-position thereof in view of hue of the color-forming dye or color density.

As cyan couplers which may be used in the present invention, in addition to the cyan dye-forming couplers as described above, hydrophobic nondiffusible naphthonic and phenolic couples may be used. Preferred examples of such cyan couplers include oxygen-releasing type 2-equivalent naphtholic couplers.

A coupler which provides a color-forming dye having a proper diffusibility may be used in combination with the above described couplers to improve the graininess. Specific examples of such couplers include magenta couplers as described in U.S. Pat. No. 4,366,237, and yellow, magenta and cyan couplers as described in European Patent No. 96,570.

The above described dye-forming couplers and special couplers may form a dimer or higher polymer. Typical examples of polymerized dye-forming couplers are described in U.S. Pat. No. 3,451,820. Specific examples of polymerized magenta couplers are described in U.S. Pat. No. 4,367,292.

Couplers which release a photographically useful residual group may be preferably used in the present invention. Useful examples of DIR couplers which release a development inhibitor are described in patents cited in Research Disclosure, RD No. 17643 (VIIF).

The present light-sensitive material may comprise a coupler which imagewise releases a nucleating agent or a development accelerator or a precursor thereof upon development. Specific examples of such a coupler are described in British Patent Nos. 2,097,140 and 2,131,188. Other examples of such a coupler which may be used in the present invention include DIR redox compound-releasing couplers as described in Japanese Patent Application (OPI) No. 185950/85, and couplers which release a dye which restores color after coupling release as described in European Patent No. 173,302A.

The incorporation of the present couplers in the light-sensitive material can be accomplished by various known dispersion methods. Examples of high boiling point solvents which can be used in an oil-in-water dispersion method are described in U.S. Pat. No. 2,322,027. Specific examples of the process and effects of the latex dispersion method and latex for such dispersion method are described in U.S. Pat. No. 4,199,363 and West German Patent Application (OLS) Nos. 2,541,274 and 2,541,230.

The light-sensitive material to be used in the present invention may contain as a color antifoggants or color stain inhibitors hydroquinone derivatives, aminophenol derivatives, amine derivatives, gallic acid derivatives, catechol derivatives, ascorbic acid derivatives, colorless couplers, sulfonamidophenol derivatives or the like.

The light-sensitive material to be used in the present invention may comprise a known discoloration inhibitor. Typical examples of such a known discoloration inhibitor include hindered phenols such as hydroquinones, 6-hydroxycoumarones, 5-hydroxycoumarans, spirochromans, p-alkoxyphenols, hindered phenols or bisphenols, gallic acid derivatives, methylenedioxybenzenes, aminophenols, hindered amines, and ether or ester derivatives obtained by silylating or alkylating phenolic hydroxyl groups thereof. Furthermore, metal complexes such as (bissalicylaldoximate)nickel complex and (bis-N,N-dialkyldithiocarbamate)nickel complex may be used.

In the present photographic light-sensitive material, the photographic emulsion layer and other layers may be coated on a flexible support such as plastic film commonly used for photographic light-sensitive materials.

The coating of the photographic emulsion layer and other layers onto the support can be accomplished by any suitable method such as a dip coating method, a roller coating method, a curtain coating method and an extrusion coating method.

The present invention can be applied to various color light-sensitive materials, for example, color light-sensitive materials for a color negative film for a motion picture, a color reversal film for a slide or TV, a color paper, a color positive film or a color reversal paper.

The present invention will be further illustrated in the following examples, but the present invention should not be construed as being limited thereto.

Unless otherwise specified, all ratios, percents, etc., are by weight.

Washing Solution (mother liquor was also used as replenisher):

City water was passed through a mixed bed column filled with a strongly acidic H type cation exchange resin (Amberlite IR-120B manufactured by Rohm & Haas Co.) and an OH type anion exchange resin (Amberlite IR-400 manufactured by Rohm & Haas Co.) so that the concentration of calcium and magnesium ions were reduced to 3 mg/liter or less. Sodium bichlorinated isocyanurate and sodium sulfate were added to the water in amounts of 20 mg/liter and 1.5 g/liter, respectively.

The pH of the washing solution thus prepared was in the range of 6.5 to 7.5.

The above described specimens were then subjected to a continuous processing. The amount of the bleaching solution and blixing solution replenished were changed as shown in Table I-2(Processing A).

Specimen 101 was subjected to a continuous processing in the same manner as in Processing A except that the undermentioned bleaching accelerator was added to the bleaching solution (Processing B). ##STR73##

The added amount of this bleaching accelerator was 5×10^-3 mol/liter-the bleaching solution.

Specimen 101 was also subjected to a continuous processing in the same manner as in Processing A except that the undermentioned bleaching accelerator was added to the bleaching solution (Processing C). ##STR74##

The added amount of this bleaching accelerator was 5×10^-3 mol/liter-the bleaching solution. At the beginning and the end of each continuous processing, specimens which had been exposed to light of 4,200° K. 20 CMS were processed. These specimens thus processed were measured for the amount of residual silver by a flourescent X-ray analysis method. After the continuous processings, the bleaching solution and the blixing solution were examined for the presence of any precipitate. The results are shown in Table I-2.

Table I-2 shows that the present light-sensitive material specimens can provide images having a small amount of residual silver even if processed with a lesser amount of the processing solution replenished at the desilvering step. The results also show that the present light-sensitive material specimens leave a small amount of precipitate in the processing solution.

EXAMPLE I-2

Specimens 106 and 107 having different coated amounts of silver from Specimen 104 were prepared in the same manner as in Specimen 104 except that the coated amount of each layer was changed. These specimens were then subjected to a continuous processing in the same masnner as in Processing A of Example I-1.

In the same manner as in Example I-1, these specimens were examined for the amount of residual silver at the beginning, the middle and the end of the continuous processing. These specimens were also checked for the presence of precipitate in the bleaching solution and the blixing solution after being processed. The results are shown in Table I-3.

Second Washing Solution (mother liquor was also used as replenisher):

City water was passed through a mixed bed column filled with a strongly acidic H type cation exchange resin (Amberlite 1R-120B manufactured by Rohm & Haas Co.) and an OH type anion exchange resin (Amberlite 1R-400 manufacture by Rohm & Haas Co. ) so that the concentration of calcium and magnesium ions were reduced to 3 mg/liter or less. Sodium dichlorinated isocyanurate and sodium sulfate were added to the water in amounts of 20 mg/liter and 1.5 g/liter, respectively. The pH of the solution was in the range of 6.5 to 7.5.

The above described specimens which had been exposed to light of 3,200° K. 100 CMS through an optical wedge were measured for the amount of residual silver at the minimum density portion and maximum density portion of yellow image and observed for the condition of the bleaching solution and the blixing solution at the beginning, middle and end of the continuous processing. Furthermore, these specimens were subjected to various continuous processings with different supply amount of the bleaching solution and the blixing solution. The results are shown in Table I-7.

Table I-7 shows that the present processing method leaves a small amount of residual silver and provides an excellent image having a low minimum density in the same manner as Example I-1. However, Specimen 205 having much silver coated thereon shows an increase in the amount of residual silver.

The specimens were processed with the above described processing solutions and washing solution in the above described processing steps. The results were compared.

Washing Solution:

City water was passed through a mixed bed column filled with a strongly acidic H type cation exchange resin (Dialon SK-1B, manufactured by Mitsubishi Chemical Industries, Ltd.) and a strongly basic OH type anion exchange resin (Diaion SA-10A, manufactured by Mitsubishi Chemical Industries, Ltd.) so that the water having the undermentioned composition was obtained. Sodium dichlorinated isocynanurate was added to the water as a disinfectant in an amount of 20 mg/liter.

Processing (B):

Processing (B) was conducted in the same manner as Processing (A) except that NH₄ [Fe(III) (EDTA)] and EDTA.2Na in the blixing solution were replaced by the equimolecular amounts of NH₄ [FE(III)(DTPA)] (ferric ammonium diethylenetriaminepentaacetate) and diethylenetriaminepentaacetic acid as bleaching agents.

Processing (C):

Processing (C) was conducted in the same manner as Processing (A) except that ammonium iodide was added to the blixing solution in an amount of 1.20 g/liter, the light-sensitive material specimens wre not exposed to light, and the blixing was conducted for 2 minutes. Thus, the fixation of unexposed silver halide was examined.

Processing (D):

Processing (D) was conducted in the same manner as Processing (B) except that ammonium iodide was added to the blixing solution in an amount of 1.20 g/liter, the light-sensitive material specimens were not exposed to light, and the blixing was conducted for 2 minutes.

Processing (E):

Processing (E) was conducted in the same manner as Processing (A) except that 2-mercapto-1,3,4-triazole was added to the blixing solution as a known bleaching accelerator in an amount of 0.40 g/liter.

Processing (F):

Processing (F) was conducted in the same manner as Processing (E) except that ammonium iodide was added to the blixing solution in an amount of 1.2 g/liter, the light-sensitive material specimens were not exposed to light, and the blixing was conducted for 2 minutes.

After being subjected to the above described Processings (A), (B), (C), (D), (E) and (F), the light-sensitive material specimens were examined for the amount of residual silver. The results are shown in Table II-2.

Table II-2 shows many interesting results. For the examination of the blixing capability, the use of the present bleaching accelerator-releasing couplers provides excellent images with a lesser amount of residual silver both in Processings (A) and (B) as compared to the case where the present bleaching accelerator-releasing couplers are not used. On the other hand, an unexpected result was obtained in the examination of the fixing capability in Processings (C) and (D). Particularly, if no bleaching accelerator-releasing couplers are used, the blixing solution in worse in the fixing capability when it comprises a ferric diethylenetriaminepentaacetate complex salt (DTPA.Fe) as a bleaching agent than when it comprises a ferric ethylenediaminetetraacetate (EDTA.Fe). It was also found that the fixing capability is further deteriorated when the blixing solution contains a known bleaching accelerator. On the contrary, it was found that the light-sensitive materials comprising the present bleaching accelerator-releasing couplers give a surprising result. Particularly, the light-sensitive materials comprising the present bleaching accelerator-releasing couplers exhibit a better fixing capability when DPTA.Fe is used than when no DTPA/Fe is used. Furthermore, it was found that the specimens comprising the cyan dye-forming couplers represented by the formulae (L-I) and (L-II) further improve their fixing capability. These results are probably because DTPA.Fe(III) complex salt has a larger molecular weight than EDTA Fe(III) complex salt and therefore tends to interact with gelatin, coupler, etc., in the emulsion layer in the specimens, deteriorating the diffusiblity of the fixing agent (S₂ O₃ ^2- salt) in the emulsion layer. It is believed that such interaction can be relaxed by the bleaching accelerator-releasing compound of the present invention.

 **Invention

EXAMPLE II-2

500 ml of each blixing solution to be used in Processings (A) and (B) was put into a 1 liter beaker and allowed to stand open at a temperature of 25° C. The two blixing solutions wre compared for the number of days they produced sulfur particles (sulfurization). The results were as follows.

______________________________________                                    
Processing (A) (EDTA.Fe)                                                  
                      12 days                                             
Processing (B) (DTPA.Fe)                                                  
                      30 days or more                                     
______________________________________

Thus, it was found that the blixing solution comprising a DTPA Fe (Processing (B)) is less susceptible to sulfurization and more excellent in stability than the blixing solution comprising EDTA Fe (Processing (A)).

EXAMPLE II-3

The specimens prepared in Example II-1 were stored at a temperature of 80° C. and a relative humidity of 70% for 7 days, and then examined for cyan density. On the other hand, the same specimens wre rebleached with a processing solution ("CN-16 N₂ ", manufactured by Fuji Photo Film Co., Ltd.) at a temperature of 38° C. for 10 minutes, and then examined for deterioration in color restoration. The results are shown in Table II-3. Table II-3 shows that the use of the cyan dye-forming couplers represented by the formulae (L-I) and (L-III) gives excellent results in preservation of cyan images and color restoration.
