Description: FIELD OF THE INVENTION The present invention relates to a composition for the processing of a silver halide color photographic material. More particularly, the present invention relates to a processing composition containing a novel bleaching agent for use in the bleaching step after color development and a process for the processing of a silver halide color photographic material with said processing composition. BACKGROUND OF THE INVENTION A silver halide color photographic material (hereinafter referred to as a "color light-sensitive material") is essentially imagewise exposed to light, and then subjected to color development and desilvering. In the color development process, silver halide grains which have been exposed to light are reduced by a color developing agent to silver, and the resulting oxidation product of the color developing agent reacts with a coupler to form a dye image. In the subsequent desilvering step, developed silver produced at the development step is oxidized (bleached) with a bleaching agent having an oxidizing power to a silver salt which is then removed from the light-sensitive layer together with unused silver halide grains by a fixing agent which renders these silver salts and silver halide soluble (fixing). Bleaching and fixing may be effected separately as bleaching step and fixing step, or together as a blix step. These processing steps are further described in James, "The Theory of Photographic Process", 4th edition, 1977. For the purpose of maintaining desired photographic and physical properties of the dye image or for maintaining processing stability, various auxiliary steps may be added to these essential processing steps. Examples of these auxiliary steps include a rinse (with water) step, a stabilizing step, a film hardening step, and a stop step. These processing steps are normally effected by means of an automatic developing machine. In recent years, small-sized automatic developing machines called "mini-labo" have been installed in retail stores to provide rapid processing services to customers. Under these circumstances, it has been keenly desired to speed up processing. It has also been desired to considerably speed up the bleaching step. However, the ferric complex of ethylenediaminetetraacetic acid, which has been heretofore used in the art, is essentially disadvantageous in that its oxidizing power is weak. In spite of some improvements such as the use of bleach accelerators (e.g., addition of mercapto compounds as described in U.S. Patent 1,138,842), the objective, i.e., rapid bleaching has not yet been attained. Furthermore, when such a bleach accelerator is used, the bleaching power is considerably reduced due to the deterioration of the bleach accelerator, making it impossible to reduce the replenishment rate. As a result, the objective of considerably reducing the amount of waste liquid cannot be attained. As bleaching agents which can attain rapid bleach there have been known red prussiate, iron chloride, bromate, etc. However, red prussiate cannot be widely used due to problem of environmental protection. Iron chloride cannot be widely used due to the inconvenience of difficult handling due to metallic corrosion. Bromates cannot be widely used due to the solution instability. It has therefore been desired to provide a bleaching agent which provides for a rapid bleaching that can be effected with ease of handling and without any problem of discharge of waste liquid. In recent years, ferric complexes of 1,3-diaminopropanetetraacetic acid have been disclosed as bleaching agents which can meet these requirements. However, these bleaching agents have some disadvantages. One of these disadvantages is that these bleaching agents cause bleach fogging accompanied by bleach. As a process for eliminating bleach fogging there has been proposed a process which comprises the addition of a buffer to the bleaching solution (disclosed, for example, in JP-A-1-213657). (The term "JP-A" as used herein means an "unexamined published Japanese patent application".) However, this improvement leaves much to be desired. In particular, in the case of rapid processing where color development is effected in 3 minutes, heavier bleach fogging can be caused due to the use of a highly active developer. Further, the use of a processing solution having a bleaching capacity comprising a ferric complex of 1,3-diaminopropanetetraacetic acid causes an increase in stain during storage of the photographic material after processing. Another problem is that the use of a bleaching solution comprising a ferric complex of 1,3-diaminopropanetetraacetic acid causes an intensification of magenta dye on the dye image portion which leads to a change in gradation during storage after processing. A further problem is that when a shorter bleaching time is used, even though a bleaching solution comprising a ferric complex of 1,3-diaminopropanetetraacetic acid is used, since cyan dye on the image portion tends to become a leuco dye, the recovery to the original color is inhibited. It is also a problem that when a processing solution having bleaching capacity comprising a ferric complex of 1,3-diaminopropanetetraacetic acid is used, especially at bleach-fixing step where bleaching and fixing are carried out simultaneously, the stability of the solution is extermely poor. When such a solution is subjected to a continuous processing, desilvering capacity extremely decreases as compared with the starting of the processing, or precipitation forms. From DE-A-2554861 a bleaching composition for the processing of silver halide color photographic material comprising a metal chelate compound formed from a salt of Fe (III) and m-Xylylendiaminotetraacetic acid is known. The EP-A-0458131 discloses a processing composition for silver halide color photographic materials comprising a metal chelate compound formed of a salt of Fe(III), Mn(III), Co(III), Rh(II), Rh(III), Au(III), Au(II) and Ce(IV) and a compound of the general formula whereby R 5 and R 6 form an aromatic or heterocyclic 6-membered ring and t and u each represent 1. There is always an hydroxamic group present. The EPA-0461413 discloses a processing composition for silver halide color photographic material comprising a metal chelate compound formed from a salt of Fe(III), Mn(III), Co(III), Rh(II), Rh(III), Au(III), Au(II) and Ce(IV) and a compound of formula whereby R 5 and R 6 form an aromatic or heterocyclic 6-membered ring and t and u each represent 1. There is always an amide or thioamide group present. Documents EP-A-0 458 131 and EP-A-461 413 are comprised in the state of the art by virtue of Article 54(3) EPC. It has therefore been desired to provide a novel processing composition having a bleaching capacity which can substitute for these bleaching agents and a processing method using such a processing composition. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a processing composition which can be easily handled and causes no environmental problem of waste liquid and a processing method using such a processing composition. It is another object of the present invention to provide a processing composition having a bleaching capacity excellent in desilvering properties and a processing method using such a processing composition. It is a further object of the present invention to provide a processing composition having a bleaching capacity which causes little bleach fogging and a processing method using such a processing composition. It is a further object of the present invention to provide a processing composition having a bleaching capacity which causes little stain with time and a processing method using such a processing composition. It is a further object of the present invention to provide a processing composition having a bleaching capacity which provides rapid bleaching properties, no deterioration in the recovery to the original color and causes little gradation change with time and a processing method using such a processing composition. It is a further object of the present invention to provide a processing composition having a bleaching power with an excellent ageing stability and a processing method using the processing composition. It is a further object of the present invention to provide a processing composition which can stably maintain the above mentioned properties during a continuous processing and a processing method using such a processing composition. The above and other objects of the present invention will become more apparent from the following detailed description and examples.

The amount of the rehalogenating agent to be incorporated in the blix solution is in the range of 0.001 to 2.0 mol/ℓ, preferably 0.01 to 1.0 mol/ℓ. The bleaching composition of the present invention or blix solution used in the present invention may further comprise a bleach accelerator, a corrosion inhibitor for inhibiting the corrosion of the processing bath, a buffer for maintaining the processing solution at a desired pH range, a fluorescent brightening agent, an antifoaming agent or the like if desired. As such a bleach accelerator there can be used a compound containing a mercapto group or disulfide group as disclosed in U.S. Patents 3,893,858 and 1,138,842, German Patent 1,290,812, JP-A-53-95630 (the term "JP-A" as used herein means an "unexamined published Japanese patent application"), and Research Disclosure No. 17129 (1978), the thiazoline derivative as disclosed in JP-A-50-140129, the thiourea derivative as disclosed in U.S. Patent 3,706,561, the polyethylene oxide as disclosed in German Patent 2,748,430, the polyamine compound as disclosed in JP-B-45-8836 (the term "JP-B" as used herein means an "examined Japanese patent publication"), the imidazole compound as disclosed in JP-A-49-40493, or the like.

The pH value of the bleaching solution or blix solution of the present invention is in the range of 2.0 to 8.0, preferably 3.0 to 7.5. If the color development step is immediately followed by bleach or blix step, the processing solution is preferably used at a pH range of 6.0 or less, more preferably 5.5 or less, in order to inhibit bleach fogging. If the pH value of the processing solution falls below 2.0, the metal chelate according to the present invention becomes unstable. Therefore, the pH value of the processing solution is preferably in the range of 2.0 to 5.5. In order to adjust the pH value of the processing solution having a bleaching capacity to the above mentioned range, the above mentioned organic acid can be used in combination with an alkaline agent (e.g., aqueous ammonia, KOH, NaOH, imidazole, monoethanolamine, diethanolamine). Particularly preferred among these alkaline agents is aqueous ammonia. In the processing step, the processing solution containing complex salt of iron (III) and having a bleaching power which has been used is preferably aerated to oxidize the resulting ferrous complex. This regenerates the bleaching agent, keeping the photographic properties extremely stable. The bleach or blix step may be effected generally at a temperature of 30 to 50°C, preferably 35 to 45°C. For light-sensitive materials for picture taking, the bleaching or blix time generally ranges from 10 seconds to 5 minutes, preferably from 10 seconds to 60 seconds, more preferably from 10 seconds to 30 seconds. For light-sensitive materials for printing, the bleaching time generally ranges from 5 seconds to 70 seconds, preferably 5 seconds to 50 seconds, more preferably 5 seconds to 30 seconds, and particularly preferably 5 seconds to 15 seconds. Under these preferred processing conditions, excellent results, for example, rapid processing and no increase in stain can be provided. The fixing solution or blix solution may comprise a fixing agent. Examples of such a fixing agent include a thiosulfate, a thiocyanate, a thioether, an amine, a mercapto, a thione, a thiourea, and an iodide. Specific examples of these compounds include ammonium thiosulfate, sodium thiosulfate, potassium thiosulfate, guanidine thiosulfate, potassium thiocyanate, dihydroxyethyl-thioether, 3,6-dithia-1,8-octanediol, and imidazole. Among these compounds, thiosulfate, especially ammonium thiosulfate may be preferably used for rapid fixing. Further, two or more kinds of fixing agents can be used in combination for rapid fixing. For example, ammonium thiosulfate may be preferably used in combination with ammonium thiocyanate, imidazole, thiourea, thioether or the like. In this case, the secondary fixing agent may be used generally in an amount of 0.01 to 100 mol% based on ammonium thiosulfate. The amount of the fixing agent to be incorporated in the fixing solution or blix solution is generally in the range of 0.1 to 3.0 mol/ℓ, preferably 0.5 to 2.0 mol/ℓ. The pH value of the fixing solution depends on the kind of the fixing agent contained therein and is normally in the range of 3.0 to 9.0. In particular, if a thiosulfate is used, the pH value of the fixing solution is preferably in the range of 6.5 to 8.0 for stable fixing properties. The fixing solution and/or blix solution may comprise a preservative to enhance the aging stability thereof. The fixing solution or blix solution containing a thiosulfate may effectively comprise a sulfite and/or hydroxylamine, hydrazine or aldehyde-bisulfite adduct (e.g., acetaldehyde-bisulfite adduct, particularly aromatic aldehyde-bisulfite adduct as described in JP-A-1-298935) as a preservative. Further, sulfinic compounds as described in JP-A-62-143048 may be preferably used. The fixing solution and/or blix solution may preferably comprise a buffer to keep the pH value thereof constant. Examples of such a buffer include a phosphate, an imidazole such as imidazole, 1-methylimidazole, 2-methylimidazole, and 1-ethylimidazole, triethanolamine, N-allylmorpholine, and N-benzoylpiperadine. The fixing solution may comprise various chelating agents to opacify iron ions brought by the bleaching solution to improve the stability thereof. Preferred examples of such chelating agents include 1-hydroxyethylidene-1,1-diphosphonic acid, ethylenediamine-N,N,N',N'-tetramethylenephosphonic acid, nitrilotrimethylenephosphonic acid, ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, and 1,2-propanediaminetetraacetic acid. The fixing step may be effected generally at a temperature of 30 to 50°C, preferably 35 to 45°C. For light-sensitive materials for picture taking, the fixing time generally ranges from 35 seconds to 2 minutes, preferably from 40 seconds to 100 seconds. For light-sensitive materials for printing, the fixing time ranges from 10 seconds to 70 secons, preferably 10 seconds to 30 seconds. The desilvering step may consist of a bleach step and/or blix step in combination. Typical examples of such a combination include: i. Bleach - fixing ii. Bleach - blix iii. Bleach - rinse - fixing iv. Blix v. Fixing - blix vi. Fixing - blix - fix Light-sensitive materials for picture taking may be preferably subjected to the combination i, ii, iii, or iv, more preferably i, ii or iii. Light-sensitive material for print may be preferably subjected to the combination v. The present invention can be applied to any desilvering step which is effected after color development through the stop step, the rinse step or the like. In the present desilvering step such as bleaching, blix and fixing, the agitation is preferably intensified as much as possible to more effectively accomplish the effects of the present invention. In particular, the agitation can be intensified by various methods. For example, the processing solution may be jetted to the surface of the emulsion layer of the light-sensitive material as described in JP-A-62-183460 and 62-183461. The agitating effect can be improved by a rotary means as described in JP-A-62-183461. Furthermore, the agitating effect can be improved by moving the light-sensitive material with the emulsion surface in contact with a wiper blade provided in the bath so that a turbulence occurs on the emulsion surface. Moreover, the agitation can be intensified by increasing the total circulated amount of processing solution. Such an agitation improving method can be effectively applied to the bleaching bath, blix bath or fixing bath. The improvement in agitation effect expedites the supply of a bleaching agent, fixing agent or the like into the emulsion film, resulting in an improvement in desilvering rate. The above mentioned agitation improving method is more effective when a bleach accelerator is used. In this case, the agitation improving method can remarkably enhance the bleach accelerating effect or eliminate the effect of inhibiting fixation by the bleach accelerator. The above mentioned strong agitation may be used in the color development, rinse with water or stabilization. The color developer used in the present color development may comprise a known aromatic primary amine color developing agent. Preferred examples of such an aromatic primary amine color developing agent include p-phenylenediamine derivatives.

Typical examples of such additives include developing agents such as 1-phenyl-3-pyrazolidone, methol and hydroquinone, preservatives such as sulfite, accelerators comprising alkali such as sodium hydroxide, sodium carbonate and potassium carbonate, inorganic or organic inhibitors such as potassium bromide, 2-methylbenzimidazole and methylbenzthiazole, water softners such as polyphosphoric acid, and development inhibitors comprising iodides (in a slight amount) or mercapto compound. The present processing process essentially consists of the above mentioned color development step and the subsequent desilvering step, preferably followed by rinse step and/or stabilizing step. The rinsing water to be used in the rinsing step can comprise various surface active agents to inhibit unevennes due to waterdrop at the time of drying the light-sensitive material after processing. Examples of these surface active agents include polyethylene glycol type nonionic surface active agents, polyvalent alcohol type nonionic surface active agents, alkylbenzenesulfonate type anionic surface active agents, higher alcohol sulfuric ester type anionic surface active agents, alkylnaphthalene sulfonate type anionic surface active agents, quaternary ammonium salt type cationic surface active agents, amine salt type cationic surface active agents, amino acid type amphoteric surface active agents, and betaine type amphoteric surface active agents. However, ionic surface active agents can react with various ions introduced into the system upon processing to form insoluble substances. Therefore, nonionic surface active agents may be preferably used. In particular, alkylphenol-ethylene oxide adducts may be preferably used. Particularly preferred examples of such alkylphenols include octyl, nonyl, dodecyl, and dinonylphenol. The molar amount of ethylene oxide to be added is preferably 8 to 14. In addition, silicone surface active agents, which exhibit a high antifoaming effect, may be preferably used. The rinsing solution may contain various anti-bacterial agents and anti-fungal agents to inhibit the formation of fur and the proliferation of mold on the light-sensitive material which has been processed. Examples of these anti-bacterial agents and anti-fungal agents include thiazolylbenzimidazole compounds as disclosed in JP-A-57-157244 and 58-105145, isothiazolone compounds as disclosed in JP-A-54-27424 and 57-8542, chlorophenolic compounds such as trichlorophenol, bromophenolic compounds, organic tin or zinc compounds, thiocyanic or isothiocyanic compounds, acid amide compounds, diazine or triazine compounds, thiourea compounds, benzotriazolealkyl guanidine compounds, quaternary ammonium salts such as benzammonium chloride, antibiotics such as penicilline, and general-purpose anti-fungal agents as described in Journal of Antibacterial and Antifungal Agents", Vol. 1, No. 5, p 207 - 223 (1983). Two or more of these antibacterial or anti-fungal agents can be used in combination. Various germicides as described in JP-A-48-83820 can be used. Various chelating agents may be preferably incorporated in the system. Preferred examples of these chelating agents include aminopolycarboxylic acid such as ethylenediaminetetraacetic acid and diethylenetriaminepentaacetic acid, organic phosphonic acid such as 1-hydroxyethylidene-1,1-diphosphonic acid and ethylenediamine-N,N,N',N'-tetramethylenephosphonic acid, and hydrolyzates of anhydrous maleic polymers as described in European Patent 345172A1. Preservatives which can be incorporated in the above mentioned fixing solution or blix solution may be preferably incorporated in the rinsing solution. As the stabilizing solution to be used in the stabilizing step there can be used a processing solution for stabilizing dye images. Examples of such a processing solution include solution preferably with a pH value of 3 to 6 having a buffering capability, and solution containing an aldehyde (e.g., formalin, glutaraldehyde), hexamethylenetetramine compound, hexahydrotriazine compound or N-methylol compound disclosed in JP-A-2-153348 and U.S. Patent 4,859,574. The stabilizing solution may contain all compounds which can be incorporated in the rinsing solution. The stabilizing solution may optionally further contain an ammonium compound such as ammonium chloride and ammonium sulfite, metallic compound such as Bi and Al, fluorescent brightening agent, various dye stabilizers such as N-methylol compound as described in JP-A-2-153350 and JP-A-2-153348, and U.S. Patent 4,859,574, film hardener, and alkanolamine as described in U.S. Patent 4,786,583. A stabilization method using the above mentioned dye stabilizers may also be used. The rinsing step or stabilizing step is preferably effected in a multistage countercurrent process. The number of stages is preferably 2 to 4. The replenishment rate of the rinsing solution or stabilizing solution is generally 1 to 50 times, preferably 2 to 30 times, more preferably 2 to 15 times the amount of the solution to be brought over from the preceding bath per unit area. As water to be used in the rinsing step or stabilizing step there may be preferably used tap water, water obtained by deionizing water with an ion exchange resin so that Ca and Mg concentrations are each reduced to 5 mg/ℓ or less, and water sterilized by halogen, ultraviolet ray, etc. As water for making up for the evaporation loss there may be used tap water, preferably the above mentioned deionized or sterilized water which can be preferably used in the the rinsing step or stabilizing step. In the present invention, in order to correct for the concentration due to evaporation in the bleaching solution and blix solution as well as other processing solutions, a proper amount of water or correcting solution or processing replenisher may be preferably supplied into the system. The overflow solution from the rinsing step or stabilizing step can be flown into a preceding bath having a fixing capability to reduce the amount of the processing solution to be discharged. The processing method of the present invention may be preferably effected by means of an automatic developing machine. Conveying methods in such an automatic developing machine are described in JP-A-60-191257, JP-A-60-191258, and JP-A-60-191259. In order to speed up the processing, the crossover time between processing baths in the automatic developing machine is preferably minimized. An automatic developing machine with a crossover time of 10 seconds or less is described in JP-A-1-319038. When a continuous processing is effected by means of an automatic developing machine in accordance with the processing method of the present invention, a replenisher may be preferably supplied into the system depending on the amount of the light-sensitive material which has been processed in order to make up for the consumption of components of the processing solution accompanied by the processing of the light-sensitive material or inhibit the accummulation of undesired components eluted from the light-sensitive material in the processing solution. Further, two or more procesing baths may be provided in each processing step. In this case, a countercurrent process may be preferably used wherein a replenisher flows from one bath to its preceding bath. In particular, the rinse step and the stabilizing step may be preferably effected in a 2- to 4-stage cascade system. The amount of the replenisher to be supplied may be preferably reduced so far as the change in the composition of each processing solution doesn't cause any deterioration of photographic properties or other troubles such as solution contamination. For color light-sensitive materials for picture taking, the amount of the color developer replenisher to be supplied is generally in the range of 100 ml to 1,500 ml, preferably 100 ml to 1,000 ml per m 2 of light-sensitive material. For color light-sensitive materials for print, the amount of the color developer replenisher to be supplied is generally in the range of 20 ml to 500 ml, preferably 30 ml to 200 ml per m 2 of light-sensitive material. For color light-sensitive materials for picture taking, the amount of the bleaching solution replenisher to be supplied is generally in the range of 10 ml to 500 ml, preferably 10 ml to 160 ml per m 2 of light-sensitive material. For color light-sensitive materials for print, the amount of the bleaching solution replenisher to be supplied is generally in the range of 20 ml to 300 ml, preferably 50 ml to 150 ml per m 2 of light-sensitive material. For color light-sensitive materials for picture taking, the amount of the blix solution replenisher to be supplied is generally in the range of 100 ml to 3,000 ml, preferably 200 ml to 1,300 ml per m 2 of light-sensitive material. For color light-sensitive materials for print, the amount of the blix solution replenisher to be supplied is generally in the range of 20 ml to 300 ml, preferably 50 ml to 200 ml per m 2 of light-sensitive material. The blix solution replenisher may be supplied as monobath or separately as bleaching composition and fixing composition. Alternatively, the overflow solution from the bleaching bath and/or the fixing bath may be mixed to provide a blix solution replenisher. For color light-sensitive materials for picture taking, the amount of the fixing solution replenisher to be supplied is generally in the range of 300 ml to 3,000 ml, preferably 300 ml to 1,000 ml per m 2 of light-sensitive material. For color light-sensitive materials for print, the amount of the fixing solution replenisher to be supplied is in the range of 20 ml to 300 ml, preferably 50 ml to 200 ml per m 2 of light-sensitive material. The replenishment rate of the rinsing solution or stabilizing solution is generally 1 to 50 times, preferably 2 to 30 times, more preferably 2 to 15 times the amount of the solution to be brought over from the preceding bath per unit area. In order to further reduce the replenishment rate for environmental protection, various regeneration methods may be preferably used in combination. The regeneration of the processing solution may be effected while the processing solution is circulated in the automatic developing machine. Alternatively, the processing solution may be removed from the processing bath, subjected to a proper regeneration treatment, and then returned to the processing bath as replenisher. The regeneration of the developer can be accomplished by the ion exchange with an anionic exchange resin, the removal of accummulated substances by electrodialysis and/or the addition of a chemical as regenerant. The percent regeneration is preferably 50% or more, more preferably 70% or more. As such an anionic exchange resin there may be used one commercially available. An ion exchanger having a high selectivity as disclosed in JP-A-63-11005 may be preferably used. The metal chelate bleaching agent contained in the bleaching solution and/or blix solution becomes a reduced state upon bleach. When the metal chelate of the reduced state is accummulated, the bleaching capacity is lowered. In some cases, the image dye becomes a leuco dye, causing a drop in the image density. Therefore, the bleaching solution and/or blix solution may be preferably subjected to a continuous regeneration treatment in linkage with processing. Specifically, an air pump may be preferably used to blow air through the bleaching solution and/or blix solution so that the metal chelate of the reduced state is reoxidized with oxygen (so-called aeration). The regeneration of the processing solution may also be accomplished by the addition of an oxidizing agent such as hydrogen peroxide, persulfate and bromate. The regeneration of the fixing solution or blix solution can be accomplished by electrolytic reduction of accummulated silver ions. Accummulated halogen ions may be preferably removed by an anionic exchange resin to maintain the desired fixing properties. In order to reduce the amount of rinsing solution to be used, ion exchange or ultrafiltration may be used. In particular, ultrafiltration may be preferably used. The photographic light-sensitive material adapted for the present processing can comprise at least one blue-sensitive layer, at least one green-sensitive layer and at least one red-sensitive layer on a support. The number of silver halide emulsion layers and light-insensitive layers and the order of arrangement of these layers are not specifically limited. In a typical embodiment, the silver halide photographic material comprises light-sensitive layers consisting of a plurality of silver halide emulsion layers having substantially the same color sensitivity and different light sensitivities on a support. The light-sensitive layers are unit light-sensitive layers having a color sensitivity to any of blue light, green light and red light. In the multi-layer silver halide color photographic material, these unit light-sensitive layers are normally arranged in the order of red-sensitive layer, green-sensitive layer and blue-sensitive layer as viewed from the support side. However, the order of arrangement can be optionally reversed depending on the purpose of application. Alternatively, two unit light-sensitive layers having the same color sensitivity can be arranged with a unit light-sensitive layer having a different color sensitivity interposed therebetween. Light-insensitive layers such as various interlayers can be provided between these silver halide light-sensitive layers and on the uppermost layer and lowermost layer. These interlayers can comprise couplers, DIR compounds or the like as described in JP-A-61-43748, JP-A-59-113438, JP-A-59-113440, JP-A-61-20037 and JP-A-61-20038. These interlayers can further comprise a color stain inhibitor, ultraviolet absorbent, stain inhibitor, etc. as commonly used. The plurality of silver halide emulsion layers constituting each unit light-sensitive layer can be preferably in a two-layer structure, i.e., high sensitivity emulsion layer and low sensitivity emulsion layer, as described in West German Patent 1,121,470 and British Patent 923,045. In general, these layers are preferably arranged in such an order that the light sensitivity becomes lower towards the support. Furthermore, a light-insensitive layer can be provided between these silver halide emulsion layers. As described in JP-A-57-l12751, JP-A-62-200350, JP-A-62-206541, and JP-A-62-206543, a low sensitivity emulsion layer can be provided remote from the support while a high sensitivity emulsion layer can be provided nearer to the support. In an embodiment of such an arrangement, a low sensitivity blue-sensitive layer (BL), a high sensitivity blue-sensitive layer (BH), a high sensitivity green-sensitive layer (GH), a low sensitivity green-sensitive layer (GL), a high sensitivity red-sensitive layer (RH), and a low sensitivity red-sensitive layer (RL) can be arranged in this order remote from the support. In another embodiment, BH, 3L, GL, GH, RH, and RL can be arranged in this order remote from the support. In a further embodiment, BE, BL, GH, GL, RL, and RH can be arranged in this order remote from the support. As described in JP-B-55-34932, a blue-sensitive layer, GH, RH, GL, and RL can be arranged in this order remote from the support. Alternatively, as described in JP-A-56-25738 and JP-A-62-63936, a blue-sensitive layer, GL, RL, GH, and RH can be arranged in this order remote from the support. As described in JP-B-49-15495, a layer arrangement can be used such that the uppermost layer is a silver halide emulsion layer having the highest sensitivity, the middle layer is a silver halide emulsion layer having a lower sensitivity, and the lowermost layer is a silver halide emulsion layer having a lower sensitivity than that of the middle layer. In such a layer arrangment, the light sensitivity becomes lower towards the support. Even if the layer structure comprises three layers having different light sensitivities, a middle sensitivity emulsion layer, a high sensitivity emulsion layer and a low sensitivity emulsion layer can be arranged in this order remote from the support in a color-sensitive layer as described in JP-A-59-2024643. As described above, various layer structures and arrangements can be selected depending on the purpose of light-sensitive material. Any of these layer arrangements can be applied to the color light-sensitive material used in the present invention. In the present invention, the dried thickness of all the constituting layers of the color light-sensitive material except for support and its subbing layer is preferably in the range of 20.0 µm or less, more preferably 18.0 µm or less to accomplish the objects of the present invention. The specification of the dried film thickness is based on the color developing agent to be incorporated into these constituting layers during and after processing. This means that bleach fogging or stain during the storage of images after processing depends greatly on the amount of the remaining color developing agent. In respect to the occurrence of bleach fogging or stain, the increase in magenta color probably due to the green-sensitive layer is greater than that in cyan and yellow colors. The lower limit of the specified film thickness is preferably lowered from the above mentioned specification to such an extent that the properties of the light-sensitive material is not remarkably deteriorated. The lower limit of the total dried thickness of the layers constituting the light-sensitive material except support and its subbing layer is 12.0 µm. The lower limit of the total dried thickness of the constituting layers provided between the light-sensitive layer nearest to the support and the subbing layer of the support is 1.0 µm. The reduction of the film thickness may be effected in either light-sensitive layer or light-insensitive layer. The film thickness of the multilayer color light-sensitive material used in the present invention can be determined in accordance with the following method: The light-sensitive material specimen is stored at a temperature of 25°C and a relative humidity of 50% for 7 days. The total thickness of the specimen is determined. The coating layers are then removed from the support. The thickness of the support is determined. The difference in the two measurements is the total thickness of the coating layers. The measurement of the film thickness can be accomplished by means of a contact type thickness meter comprising a piezoelectric element (e.g., K-402B Stand, available from Anritus Electric Co., Ltd.). The removal of the coating layers from the support can be effected by the use of an aqueous solution of sodium hypochlorite. A section of the specimen is photographed by a scanning type electron microscope preferably at 3,000 power or more. The total thickness of the coating layers on the support and the thickness of each of these coating layers are measured and compared to the measured value of the total thickness of the coating layers obtained by the film thickness meter (absolute value of the measured thickness) to calculate the thickness of each of these coating layers. The percent swelling of the light-sensitive material used in the present invention [determined by (equilibrium swollen film thickness in water at 25°C - total dried film thickness at 25°C, 55%RH/total dried film thickness at 25°C, 55%RH) × 100] is preferably in the range of 50 to 200%, more preferably 70 to 150%. If this value deviates from the above specified range, the remaining amount of the color developing agent increases, giving adverse effects on photographic properties, desilvering property and other picture qualities, and film physical properties such as film strength. The swelling rate of the light-sensitive material used in the present invention (as determined by T1/2, which is defined by the time required to reach half the saturated swollen film thickness (90% of the maximum swollen film thickness in the color developer (at a temperature of 30°C, 195 seconds)) is preferably in the range of 15 seconds or less, more preferably 9 seconds or less. The silver halide to be incorporated in the photographic emulsion layer in the color light-sensitive material used in the present invention may be any silver halide composition such as silver chloride, silver bromide, silver bromochloride, silver bromoiodide, silver chloroiodide and silver bromochloroiodide. Silver halide grains in the photographic emulsions may be so-called regular grains having a regular crystal form, such as cube, octahedron and tetradecahedron, or those having an irregular crystal form such as sphere and tabular, those having a crystal defect such as twinning plane, or those having a combination of these crystal forms. The silver halide grains may be either fine grains of about 0.2 µm or smaller in diameter or giant grains having a projected area diameter of up to about 10 µm. The emulsion may be either a monodisperse emulsion or a polydisperse emulsion. The preparation of the silver halide photographic emulsion which can be used in the present invention can be accomplished by any suitable method as described in Research Disclosure No. 17643 (December 1978), pp. 22-23, and No. 307105 (November 1989), pp. 863-865, "I. Emulsion Preparation and Types", and No. 18716 (November 1979), page 648, Glafkides, "Chimie et Physique Photographique", Paul Montel (1967), G.F. Duffin, "Photographic Emulsion Chemistry", Focal Press, 1966, and V.L. Zelikman et al., "Making and Coating Photographic Emulsion Focal Press", 1964. Furthermore, monodisperse emulsions as described in U.S. Patents 3,574,628 and 3,655,394, and British Patent 1,413,748 can be preferably used in the present invention. Tabular grains having an aspect ratio of about 5 or more can also be used in the present invention. The preparation of such tabular grains can be easily accomplished by any suitable method as described in Gutoff, "Photograpahic Science and Engineering", vol. 14, pp. 248-257, 1970, U.S. Patents 4,434,226, 4,414,310, 4,433,048, and 4,439,520, and British Patent 2,112,157. The individual silver halide crystals may have either a homogeneous structure or a heterogeneous structure composed of an inner portion and an outer portion differing in halogen composition, or may have a layered structure. Furthermore, the grains may have fused thereto a silver halide having a different halogen composition or a compound other than silver halide, e.g., silver thiocyanate, lead oxide, etc. by an epitaxial junction. Mixtures of grains having various crystal forms may also be used. The silver halide emulsion to be used in the present invention is normally subjected to physical ripening, chemical ripening and spectral sensitization. Additives to be used in these steps are described in Research Disclosure Nos. 17643, 18716 and 307105 as tabulated below. Known photographic additives which can be used in the present invention are described in the above-cited three Research Disclosures as tabulated below.

The specimen further comprised B-4, B-5, W-2, W-3, F-1, F-2, F-3, F-4, F-5, F-6, F-7, F-8, F-9, F-10, F-11, F-12, F-13, and iron salts, lead salts, gold salts, platinum salts, iridium salts, and rhodium salts. Specimen 101 thus prepared was exposed to white light (color temperature of light source: 4,800°K) through an optical wedge, and then processed by means of an automatic developing machine for motion picture in the following process. The processing was continued until the accumulated replenishment of each processing solution reached 2.5 times the capacity of the tank. The processing properties set forth below were the results of the processing which was effected at that time. Processing step Step Time Temperature Replenishment rate Tank capacity Color development 3 min.15 sec. 38.0°C 23 ml 15 ℓ Bleach 50 sec. 38.0°C 5 ml 5 ℓ Blix 50 sec. 38.0°C - 5 ℓ Fixing 50 sec. 38.0°C 16 ml 5 ℓ Washing (1) 30 sec. 38.0°C - 3 ℓ Washing (2) 20 sec. 38.0°C 34 ml 3 ℓ Stabilization 20 sec. 38.0°C 20 ml 3 ℓ Drying 1 min. 55°C The washing step was effected in a counter-current process wherein the washing water flows from (2) to (1). The oveflow solution from the washing tank was all introduced into the fixing bath. The bleaching bath was provided with a subtank through which air was blown into the bleaching bath at a rate of about 200 ml/min. to aerate the bleaching solution. The processing baths were each provided with an agitating means as described in JP-A-62-183460 so that a jet of the processing solution was allowed to collide with the emulsion surface of the light-sensitive material. The replenishment of the blix bath was accomplished by replenishing the bleaching bath and the fixing bath in such an arrangement that the upper portion of the bleaching bath and the lower portion of the blix bath, and the upper portion of the fixing bath and the lower portion of the blix bath were connected to each other via a pipe in the automatic developing machine so that the overflow solution from the bleaching bath and the fixing bath resulted by replenishing was all introduced into the blix bath. The amount of the developer to be brought over to the bleaching bath, the amount of the bleaching solution to be brought over to the blix bath, the amount of the blix solution to be brought over to the fixing bath, and the amount of the fixing solution to be brought over to the washing bath were 2.5 ml, 2.0 ml, 2.0 ml, and 2.0 ml per m of 35-mm wide light-sensitive material, respectively. The time for crossover was 5 seconds in all the steps. This crossover time is included in the processing time at the previous step. The various processing solutions had the following compositions: Developer Mother Solution Replenisher Diethylenetriaminepentaacetic acid 2.0 g 2.2 g 1-Hydroxyethylidene-1,1-diphosphonic acid 3.3 g 3.3 g Sodium sulfite 3.9 g 5.2 g Potassium carbonate 37.5 g 39.0 g Potassium bromide 1.4 g 0.4 g Potassium iodide 1.3 mg - Hydroxylamine sulfate 2.4 g 3.3 g 2-methyl-4-[4-ethyl-N-(β-hydroxyethyl)amino]-aniline sulfate 4.5 g 6.1 g Water to make 1.0 ℓ 1.0 ℓ pH 10.05 10.15 Bleaching solution Mother Solution Replenisher Compound as set forth in Table 1 0.383 mol 0.547 mol Ferric nitrate nonahydrate 0.370 mol 0.528 mol Ammonium bromide 84.0 g 120.0 g Ammonium nitrate 17.5 g 25.0 g Hydroxyacetic acid 63.0 g 90.0 g Acetic acid 33.2 g 47.4 g Water to make 1.0 ℓ 1.0 ℓ pH adjusted with aqueous ammonia 3.60 2.80 Mother solution for blix bath A mixture of 15 : 85 of the above mentioned mother solution of bleaching solution and the above mentioned mother solution of fixing solution.

Dichlorinated sodium isocyanurate and sodium sulfate were then added to the solution in amounts of 20 mg/ℓ and 150 mg/ℓ, respectively. The washing solution thus obtained had a pH value of 6.5 to 7.5. Stabilizing solution (The mother solution was used also as replenisher) 37 % Formalin 2.0 ml Polyoxyethylene-p-monononylphenylether (mean polymerization degree: 10) 0.3 Disodium ethylenediaminetetraacetic acid 0.05 Water to make 1.0 ℓ pH 5.0 - 8.0 Specimen 101 thus processed was then measured for the remaining amount of silver on the maximum density portion by means of a fluorescent X-ray analyzer. The results are set forth in Table 1. The specimen was also measured for green density on the minimum density portion. Furthermore, another Specimen 101 was processed in the same manner as mentioned above except that the bleaching solution to be used in the automatic developing machine was replaced by the following reference bleaching solution causing no bleach fogging. The difference in the density on Dmin portion from that obtained by using the reference bleaching solution was determined as bleach fogging. The results are set forth in Table 1.

The results are set forth in Table 1. The results set forth in Table 1 show that as compared to the processing solutions comprising the comparative compounds the processing solution having a bleaching capacity comprising the chelate compounds used in the present invention can reduce the remaining amount of silver and cause little bleach fogging and little increase in stain after processing.

EXAMPLE 3 A multilayer color photographic paper specimen was prepared by coating on a polyethylene both sides-laminated paper support which had been corona-discharged and then provided with a gelatin subbing layer containing sodium dodecylbenzenesulfonate various photographic constiuent layers having the following compositions. The coating liquids for these layers were prepared as follows: Coating liquid for 1st laye 19.1 g of a yellow coupler (ExY), 4.4 g of a dye stabilizer (Cpd-1) and 0.7 g of a dye stabilizer (Cpd-7) were dissolved in 27.2 ml of ethyl acetate, 4.1 g of a solvent (Solv-3) and 4.1 g of a solvent (Solv-7). The solution thus obtained was then emulsion-dispersed in 185 ml of a 10% aqueous solution of gelatin containing 8 ml of 10 % sodium dodecylbenzensulfonate to prepare Emulsion Dispersion A. On the other hand, a silver bromochloride emulsion A (3 : 7 mixture (ratio of molar amount of silver) of a large size emulsion A of cubic grains with a mean grain size of 0.88 µm and a grain size distribution fluctuation coefficient of 0.08 and a small size emulsion A of cubic grains with a mean grain size of 0.70 µm and a grain size distribution fluctuation coefficient of 0.10, both having 0.3 mol% silver bromide localized on the surface thereof) was prepared by incorporating the blue-sensitive sensitizing dyes A and B as described later in amounts of 2.0×10 -4 mol and 2.5×10 -4 mol based on mol of silver in the large size emulsion A and the small size emulsion A, respectively, and then subjecting the material to chemical sensitization with a sulfur sensitizer and a gold sensitizer. Emulsion Dispersion A and Silver Bromochloride Emulsion A were then mixed and dissolved to prepare a coating liquid for the 1st layer having the following composition. Coating liquids for the 2nd to 7th layers were prepared in the same manner as in the 1st layer coating liquid. There was incorporated in each layer a sodium salt of sodium salt of 1-oxy-3,5-dichloro-s-triazine as gelatin hardener.

The results are set forth in Table 5. These photographic light-sensitive material specimens were also measured for density. Dmin values measured by green light were read from the characteristic curve. The same specimens were processed in the same manner as above except that they were processed with the following reference bleaching solution causing no bleach fogging at a temperature of 38°C at a replenishment rate of 25 ml/35 mm width and 1 m length for 390 seconds.

Dmin values were read from the characteristic curve. The difference (Δmin) in Dmin of the specimens from that obtained by using the reference bleaching solution were determined. Dmin value obtained by the reference bleaching solution was 0.60. Bleach fogging (Δmin) = (Dmin of each specimen) - (Dmin obtained by reference bleaching solution) The results are set forth in Table 5. These specimens were also measured for increase in fogging during the storage after processing. For this measurement, these specimens were stored under a wet heat condition (60°C, 70%RH) in a dark place for 4 weeks. The change in Dmin on noncolored portion between before and after storage was determined. Increae in fogging (ΔD) = (Dmin after storage) - (Dmin before storage) The results are set forth in Table 5. The results set forth in Table 1 show that as compared to the comparative compounds the present compounds are capable of reducing the remainining amount of silver while contributing to eliminating bleach fogging and stain during the storage of dye images after processing.

The results are set forth in Table 8. These photographic light-sensitive material specimens were also measured for density. Color density values D R measured by red light on the maximum color density portion were read from the characteristic curve. Another batch of these specimens were processed in the same manner as mentioned above except that the following reference bleaching solution causing no malrecovery to original color was used in stead of the above mentioned bleaching solution and bleach was effected at a temperature of 38°C at a replenishment rate of 25 ml/35 mm width and 1 m length for 600 seconds.

D R values were read from the characteristic curve. The difference (ΔD R ) in D R of the specimens from that obtained by the reference bleaching solution were determined. D R value of the specimens, obtained by the reference bleaching solution was 2.1. Malrecovery to original color (ΔD R ) = (D R obtained by reference bleaching solution) - (D R of each specimen) The results are set forth in Table 8. These specimens were also measured for change in gradation during the storage after processing. For this measurement, these specimens were stored under a wet heat condition (60°C, 70%RH) in a dark place for 4 weeks. The term "gradation (γ G )" as used herein means the "difference between the color density (D G1 ) measured by green light on the portion which has been exposed by one tenth of the exposure that gives the maximum color density measured by green light and the color density (D G2 ) measured by green light on the portion which has been exposed by one thousandth of the exposure that gives the maximum color density measured by green light on the characteristic curve. Gradation = D G1 - D G2 Change in gradation (Δγ G ) = (γ G after storage) - (γ G before storage) The results are set forth in Table 8.
