Description: The present invention relates to a silver halide color photographic material which provides improvements in interimage effect, sharpness and inhibition of fogging during preservation of raw products. It has been known that silver halide color photographic materials undergo color development in which the resulting oxidation product of an aromatic primary amine color developing agent reacts with a coupler to produce indophenol, indoaniline, indamine, azomethine, phenoxazine, phenazine, and analogous dyes, forming color images. In this process, a subtractive color process is normally employed to effect color reproduction. Silver halide emulsions which are selectively sensitive to blue, green and red light, and agents for the formation of color images complementary to these colors, i.e., yellow, magenta and cyan are used in the subtractive color process. In order to form a yellow color image, acylacetanilide or dibenzoylmethane couplers are used. In order to form a magenta color image, pyrazolone, pyrazolobenzimidazole, pyrazolopyrazole, pyrazolotriazole, cyanoacetophenone or indazolone couplers are mainly used. In order to form a cyan color image, phenol or naphthol couplers are mainly used. However, dyes thus produced from these couplers do not exhibit an ideal absorption spectrum. In particular, magenta and cyan dyes thus produced exhibit a broad absorption spectrum or subsidiary absorption in a short wavelength range. This is not desirable with respect to color reproduction in color photographic light-sensitive materials. In particular, such a subsidiary absorption in a short wavelength range tends to cause a drop in saturation. This disadvantage can be somewhat reduced by developing an interimage effect. Examples of approaches for improving this interimage effect include the use of DIR hydroquinones as disclosed in U.S. Patents 3,379,529, 3,620,746, 4,377,634, and 4,332,878, and JP-A-49-129536 (the term "JP-A" as used herein means an "unexamined published Japanese patent application"). These DIR hydroquinones undergo oxidation during development to release a development inhibitor. However, when the rate of oxidation of these hydroquinones during development is raised to such an extent that the interimage effect is improved, photographically significant disadvantages develop (e.g., increase of fogging during preservation of raw products or during development). On the contrary, when the reducing power of these DIR hydroquinones is lowered to such an extent that such an increase of fogging is developed, it causes a lack of reducing power during development and hence a lack of release of a development inhibitor, giving little or no improvements in the interimage effect. When a fog inhibitor as disclosed in U.S. Patents 2,131,038, 2,694,716, 2,444,605, and 2,232,707 is used in combination with such a DIR hydroquinone, fogging can be somewhat inhibited, but the development activity of the DIR hydroquinone is lowered, causing a drop in the interimage effect. As mentioned above, it has heretofore been very difficult to develop a great interimage effect without causing the DIR hydroquinone to increase fogging. It has thus been keenly desired to provide an approach for developing an interimage effect while preventing the DIR hydroquinone from increasing fogging. US-A-4740453 discloses a silver halide photosensitive material comprising a support and at least one silver halide emulsion layer containing a compound capable of releasing a photographically useful group. It is therefore the object of the present invention to provide a silver halide color photographic light-sensitive material which exhibits a great interimage effect without causing an increase in fogging during preservation of raw products and which exhibits a high sharpness without deteriorating graininess. Said object of the present invention is accomplished with a silver halide color photographic material comprising on a support at least one silver halide emulsion layer, said material containing at least one compound represented by formula (I) : wherein R 11 represents in which R 13 represents an alkyl, aryl or heterocyclic group, R 14 represents hydrogen and R 15 represents hydrogen,an alkyl or aryl group; R 12 represents a substituent having a Hammett's substituent constant σp of 0.3 or less; n represents an integer of 0, 1 or 2, and when n is 2, the two R 12 's may be the same or different ; B represents a timing group which releases PUG after being separated from a hydroquinone nucleus; PUG represents a development inhibitor; ℓ represents an integer; and A and A' each represents a hydrogen atom or a group capable of being removed by an alkali; and R 11 and R 12 , R 11 and A or A', R 12 and A or A', and two R 12 's may together form a ring. In addition to compounds of formula (I) the material may contain at least one compound of formula (II) or (III): wherein Q 1 represents an atomic group containing at least one hetero atom and is required for the formation of a heterocyclic group containing 5 or more members together with carbon atoms connected thereto; R 21 represents a group capable of substituting on the hydroquinone nucleus; and B, PUG, ℓ, A and A' are as defined above; wherein R 31 represents an alkyl group containing two or more carbon atoms in which the carbon atom adjacent to the carbonyl group is not substituted by a hetero atom, a cycloalkyl group, an aryl group or a heterocyclic group; R 32 and R 33 each represents hydrogen or a substituent having a Hammett's substituent constant σp of 0.3 or less; and B, PUG, ℓ, A and A' are as defined above. As a result of a further study, it was found that among the group of compounds represented by formula [III], those represented by formulae [IIIA] and [IIIB] can be used in a small amount to exhibit excellent properties. wherein R 34 represents a substituent; n' represents an integer of 2 or more; and PUG, A, A', B and ℓ are as defined above. wherein R 35 represents a substituent; m represents an integer of 1 to 5 (when m is 2 or more, the plurality of R 35 's may be the same or different); and A, A', B, PUG and ℓ are as defined in formula [I]. The inventors made extensive studies to overcome the disadvantages of the prior art DIR hydroquinones. As a result, the inventors found a surprising fact that the use of DIR hydroquinones represented by formulae [I], and optionally additionally [II] and/or [III] enables a drastic improvement in the interimage effect without causing an increase in fogging during preservation of raw products. Examples of known approaches for improving the interimage effect while preventing the DIR hydroquinone from causing an increase in fogging include the combined use of compounds as disclosed in JP-A-63-17445. In the present invention, a great interimage effect can be accomplished without causing an increase in fogging by using at least one compound represented by formula [I] in an amount less than the prior art DIR hydroquinones without using these prior art fog inhibitors.

(m.p. 165 - 166°C) SYNTHESIS EXAMPLE 8 (Synthesis of Compound III-(17)) 1) Synthesis of m-nitrobenzoic acid-2,5-dimethoxyanilide (8-1) 26 ml of thionyl chloride was added dropwise to a solution of 56.1 g of m-nitrobenzoic acid in 300 ml of acetonitrile while being cooled with ice. 52.1 g of 2,5-dimethoxyaniline was added to the reaction mixture. The reaction system was stirred at room temperature for 30 minutes. The resulting crystals were filtered off. The crude crystals thus obtained were recrystallized from acetonitrile to obtain 61 g of the desired compound. 2) Synthesis of m-nitrobenzoic acid-2,5-dimethoxyanilide (8-21) A mixture of 45 g of reduced iron, 4.5 g of ammonium chloride, 60 ml of water and 400 ml of isopropanol was stirred at an elevated temperature over a steam bath. 60 g of (8-1) thus obtained was gradually added to the reaction system. The reaction system was heated under reflux for 1 hour. The reaction mixture was cooled to room temperature where iron powder was removed by filtration. The filtrate was concentrated. The residue was dissolved in ethyl acetate, washed with water, and dried. The solvent was then distilled off.

(m.p. 189 - 190°C) The present color photographic light-sensitive material 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 present silver halide photographic material comprises light-sensitive layers containing 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 multilayer 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. However, the order of arrangement can be optionally reversed depending on the desired 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 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-57-112751, JP-A-62-200350, JP-A-62-206541, and JP-A-62-206543, a low sensitivity emulsion layer can be provided further 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 toward the support. In another embodiment, BH, BL, GL, GH, RH, and RL can be arranged in this order toward the support. In a further embodiment, BH, BL, GH, GL, RL, and RH can be arranged in this order toward the support. As described in JP-B-55-34932 (the term "JP-B" as used herein means an "examined Japanese patent publication"), a blue-sensitive layer, GH, RH, GL, and RL can be arranged in this order toward the support. Alternatively, as described in JP-A-56-25738 and 62-63936, a blue-sensitive layer, GL, RL, GH, and RH can be arranged in this order toward 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 toward the support in a color-sensitive layer as described in JP-A-59-2024643. Alternatively, a high sensitivity emulsion layer, a low sensitivity emulsion layer and a middle sensitivity emulsion layer or a low sensitivity emulsion layer, a middle sensitivity emulsion layer and a high sensitivity emulsion layer can be arranged in this order. In the case where the layer structure comprises four or more layers, the order of arrangement of the layers can also be altered as described above. In order to improve the color reproducibility, a donor layer (CL) described in U.S. Patents 4,663,271, 4,705,744 and 4,707,436 and JP-A-62-160448 and JP-A-63-89850 and having an interimage effect and a different spectral sensitivity distribution from the main light-sensitive layer such as BL, GL and RL may be preferably provided adjacent or close to the main light-sensitive layer. As described above, various layer structures and arrangements can be selected depending on the purpose of the light-sensitive material. A suitable silver halide to be incorporated in the photographic emulsion layer in the present color light-sensitive material for photographing is silver bromoiodide, silver chloroiodide or silver bromochloroiodide containing silver iodide in an amount of 30 mol % or less. Particularly suitable is silver bromoiodide containing silver iodide in an amount of 2 mol % to 25 mol %. Silver halide grains in the photographic emulsions may be so-called regular grains having a regular crystal form, such as a cube, an octahedron and a tetradecahedron, or those having an irregular crystal form such as a sphere and a tabular form, those having a crystal defect such as a twinning plane, or those having a combination of these crystal forms. The silver halide grains may be either fine grains of 0.2 µm or smaller in diameter or giant grains having a projected area diameter of up to 10 µm, preferably fine grains having a diameter of 0.1 to 0.2 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, "I. Emulsion Preparation and Types", and No. 18716 (November 1979), page 648, Research Disclosure No. 307105 (November 1989), pages 863-865, 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 can be preferably used in the present invention. Tabular grains having an aspect ratio of about 5 or more can 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 a core and an outer shell 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 or lead oxide, 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 and 18716 as tabulated below. In the present invention, finely divided light-insensitive silver halide grains are preferably used. Finely divided light-insensitive silver halide grains are finely divided silver halide grains which are not sensitive to light upon imagewise exposure for obtaining color images and are not substantially developed. Preferably, finely divided light-insensitive silver halide grains are not previously fogged. Finely divided silver halide grains have a silver bromide content of 0 to 100 mol % and may optionally contain silver chloride and/or silver iodide, preferably 0.5 to 10 mol % of silver iodide. Finely divided silver halide grains preferably have an average grain diameter of 0.01 to 0.5 µm (as calculated in terms of the average diameter of a projected area corresponding to a sphere), more preferably 0.02 to 0.2 µm. The preparation of finely divided silver halide grains can be accomplished in the same manner as ordinary light-sensitive silver halide. In this case, the surface of the silver halide grains does not need to be optically sensitized. Also, silver halide grains do not need to be spectrally sensitized. However, before being added to the coating solution, the silver halide emulsion preferably comprises a known stabilizer such as a triazole, an azaindene, a benzothiazolium or a mercapto compound incorporated therein. Known photographic additives which can be used in the present invention are also described in the above cited two references as shown in the following table.

The incorporation of these couplers in the light-sensitive material can be accomplished by any suitable known dispersion method. Examples of high boiling point solvents to be used in an oil-in-water dispersion process are described in U.S. Patent 2,322,027. Specific examples of high boiling point organic solvents having a boiling point of 175°C or higher at normal pressure which can be used in an oil-in-water dispersion process include phthalic esters (e.g., dibutyl phthalate, dicylcohexyl phthalate, di-2-ethylhexyl phthalate, decyl phthalate, bis(2,4-di-t-amylphenyl)phthalate, bis(2,4-di-t-amylphenyl)isophthalate, bis(1,1-diethylpropyl)phthalate), phosphoric or phosphonic esters (e.g., triphenyl phosphate, tricresyl phosphate, 2-ethylhexyl diphenyl phosphate, tricyclohexyl phosphate, tri-2-ethylhexyl phosphate, tridecyl phosphate, tributoxy ethyl phosphate, trichloropropyl phosphate, di-2-ethylhexyl phenyl phosphonate), benzoic acid esters (e.g., 2-ethylhexyl benzoate, dodecyl benzoate, 2-ethylhexyl-p-hydroxy benzoate), amides (e.g., N,N-diethyldodecanamide, N,N-diethyllaurylamide, N-tetradecylpyrrolidone), alcohols or phenols (e.g., isostearyl alcohol, 2,4-di-tert-amylphenol), aliphatic carboxylic esters (e.g., bis(2-ethylhexyl)sebacate, dioctyl azerate, glycerol tributylate, isostearyl lactate, trioctyl citrate), aniline derivatives (N,N-dibutyl-2-butoxy-5-tert-octylaniline), and hydrocarbons (e.g., paraffin, dodecylbenzene, diisopropyl naphthalene). As an auxiliary solvent there can be used an organic solvent having a boiling point of 30°C or higher, preferably 50°C to 160°C. Typical examples of such an organic solvent include ethyl acetate, butyl acetate, ethyl propionate, methyl ethyl ketone, cyclohexanone, 2-ethoxyethyl acetate, and dimethylformamide. The process and effects of a latex dispersion method and specific examples of latexes to be used in dipping are described in U.S. Patent 4,199,363, West German Patent Application (OLS) 2,541,274, and 2,541,230. Various preservatives or antimold agents such as 1,2-benzisothiazoline-3-one, n-butyl, p-hydroxybenzoate, phenol, 4-chloro-3,5-dimethylphenol, 2-phenoxyethanol, and 2-(4-thiazolyl)benzimidazole as described in JP-A-63-257747, 62-272248, and 1-80941 may be preferably incorporated in the present color light-sensitive material. The present invention is applicable to various types of color light-sensitive materials, particularly preferably to color negative films for common use or motion picture, color reversal films for slide or television, color papers, color positive films and color reversal papers. Suitable supports which can be used in the present invention are described in the above cited RD 17643 (page 28) and 18716 (right column on page 647 to left column on page 648). In the present light-sensitive material, the total thickness of all the hydrophilic colloidal layers on the emulsion side is preferably in the range of 28 µm or less, more preferably 23 µm or less, particularly 20 µm or less. The film swelling rate T 1/2 is preferably in the range of 30 seconds or less, more preferably 20 seconds or less. In the present invention, the film thickness is determined after being stored at a temperature of 25°C and a relative humidity of 55 % for 2 days. The film swelling rate T 1/2 can be determined by a method known in the art, e.g., by means of a swellometer of the type described in A. Green et al, "Photographic Science Engineering", vol. 19, No. 2, pp. 124-129. T 1/2 is defined as the time taken until half the saturated film thickness is reached wherein the saturated film thickness is 90 % of the maximum swollen film thickness reached when the light-sensitive material is processed with a color developer at a temperature of 30°C for 195 seconds. The film swelling rate T 1/2 can be adjusted by adding a film hardener to gelatin as binder or altering the ageing condition after coating. The percentage of swelling of the light-sensitive material is preferably in the range of 150 to 400 %. The percentage of swelling can be calculated from the maximum swollen film thickness determined as described above in accordance with the equation: (maximum swollen film thickness - film thickness)/film thickness. The color photographic light-sensitive material according to the present invention can be developed in accordance with an ordinary method as described in RD Nos 17643 (pp. 28-29), 18716 (left column - right column on page 651) and 307105 (pp. 880-881). The color developer to be used in the development of the present light-sensitive material is preferably an alkaline aqueous solution containing as a main component an aromatic primary amine color developing agent. An aminophenolic compound can be effectively used as a color developing agent. In particular, p-phenylenediamine compounds are preferably used. Typical examples of such p-phenylenediamine compounds include 3-methyl-4-amino-N,N-diethylaniline, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methoxyethylaniline, and sulfates, hydrochlorides and p-toluenesulfonates thereof. Particularly preferred among these compounds is 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline sulfate. These compounds can be used in combination of two or more thereof depending on the desired application. The color developer normally contains a pH buffer such as a carbonate and a phosphate of an alkaline metal or a development inhibitor or fog inhibitor such as bromides, iodides, benzimidazoles, benzothiazoles and mercapto compounds. If desired, the color developer may further contain various preservatives, e.g., hydroxylamine, diethylhydroxylamine, sulfites, hydrazines (e.g., N,N-biscarboxymethyl hydrazine), phenylsemicarbazides, triethanolamine, and catecholsulfonic acids; organic solvents, e.g., ethylene glycol and diethylene glycol; development accelerators, e.g., benzyl alcohol, polyethylene glycol, quaternary ammonium salts, and amines; color-forming couplers; competing couplers; auxiliary developing agents, e.g., 1-phenyl-3-pyrazolidone; viscosity-imparting agents; various chelating agents exemplified by aminopolycarboxylic acids, aminopolyphosphoric acids, alkylphosphonic acids, and phosphonocarboxylic acids, e.g., ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminoacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, nitrilo-N,N,N-trimethylenephosphonic acid, ethylenediamine-N,N,N',N'-tetramethylenephosphonic acid, and ethylenediamine-di(o-hydroxyphenylacetic acid), and salts thereof. Reversal processing is usually carried out by black-and-white development followed by color development. Black-and-white developers to be used can contain one or more of the known black-and-white developing agents, such as dihydroxybenzenes, e.g., hydroquinone, 3-pyrazolidones, e.g., 1-phenyl-3-pyrazolidone, and aminophenols, e.g., N-methyl-p-aminophenol. The color developer or black-and-white developer usually has a pH of from 9 to 12. The replenishment rate of the developer is usually 3 ℓ or less per m 2 of the light-sensitive material. However, the replenishment rate depends on the type of color photographic material to be processed. The replenishment rate may be reduced to 500 ml/m 2 or less by decreasing the bromide ion concentration in the replenisher. When the replenishment rate is reduced, it is preferable to reduce the area of the liquid surface in contact with air in the processing tank to prevent evaporation and air-oxidation of the liquid. The area of the liquid surface in contact with air can be represented by the opening value defined as follows: Opening value = Area of liquid surface in contact with air (cm 3 )/volume of liquid (cm 3 ) The opening value is preferably in the range of 0.1 or less, more preferably 0.001 to 0.05. The reduction of the opening value can be accomplished by providing a cover such as floating cover on the surface of a photographic processing solution in the processing tank, or by a process which comprises the use of a mobile cover as described in JP-A-1-82033, or a slit development process as described in JP-A-63-216050. The reduction of the opening value can be applied not only to color development and black-and-white development but also to the subsequent steps such as bleach, blix, fixing, rinse and stabilization. The replenishment rate can also be reduced by a means for suppressing accumulation of the bromide ion in the developing solution. The color development time is normally selected between 2 and 5 minutes. The color development time can be further reduced by carrying out color development at an elevated temperaure and at a high pH value with a color developing solution containing a color developing agent in a high concentration. The photographic emulsion layer which has been color-developed is normally subjected to bleach. Bleach may be effected simultaneously with fixation (i.e., blix), or these two steps may be carried out separately. For speeding up processing, bleach may be followed by blix. Further, when two blix baths connected in series are used, an embodiment wherein blix is preceded by fixation, and an embodiment wherein blix is followed by bleach may be arbitrarily selected according to the intended purpose. Bleaching agents to be used include compounds of polyvalent metals, e.g., iron (III), peroxides, quinones, and nitro compounds. Typical examples of these bleaching agents are organic complex salts of iron (III) with aminopolycarboxylic acis, e.g., ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, and glycol ether diaminetetraacetic acid, or citric acid, tartaric acid, malic acid, etc. Of these, aminopolycarboxylic acid-iron (III) complex salts such as (ethylenediaminetetraacetato)iron (III) complex salts are preferred in view of speeding up processing and conservation of the environment. In particular, aminopolycarboxylic acid-iron (III) complex salts are useful in both a bleaching solution and a blix solution. The bleaching or blix solution comprising such an aminopolycarboxylic acid-iron (III) complex salt normally has a pH value of 4.0 to 8.0. For speeding up processing, it is possible to adopt a lower pH value. The bleaching bath, blix bath or a prebath thereof can contain, if desired, a bleaching accelerator. Examples of useful bleaching accelerators include compounds containing a mercapto group or a disulfide group as described in U.S. Patent 3,893,858, West German Patent 1,290,812, and 2,059,988, JP-A-53-32736, JP-A-53-57831, JP-A-53-37418, JP-A-53-72623, JP-A-95630, JP-A-53-95631, JP-A-53-104232, JP-A-53-124424, JP-A-53-141623, and JP-A-53-28426, and Research Disclosure No. 17129 (July 1978), thiazolidine derivatives as described in JP-A-50-140129, thiourea derivatives as described in JP-B-45-8506, JP-A-52-20832, JP-A-53-32735 and U.S. Patent 3,706,561, iodides as described in West German Patent 1,127,715 and JP-A-58-16235, polyoxyethylene compounds as described in West German Patents 966,410 and 2,748,430, polyamine compounds as described in JP-B-45-8836, compounds as described in JP-A-49-40943, JP-A-49-59644, JP-A-53-94927, JP-A-54-35727, JP-A-55-26506, and JP-A-58-163940, and bromine ions. Preferred among these compounds are compounds containing a mercapto group or a disulfide group because of their great acceleratory effects. In particular, the compounds disclosed in U.S. Patent 3,893,858, West German Patent 1,290,812, and JP-A-53-95630 are preferred. The compounds disclosed in U.S. Patent 4,552,834 are also preferred. These bleaching accelerators may be incorporated into the light-sensitive material. These bleaching accelerators are particularly effective for blix of color light-sensitive materials for photography. The bleaching solution or the blix solution to be used in the present invention may preferably comprise an organic acid besides the above mentioned compounds for the purpose of inhibiting bleach stain. A particularly preferred organic acid is a compound having an acid dissociation constant (pKa) of 2 to 5. Specific examples of such an organic acid include acetic acid and propionic acid. Fixing agents to be used for fixation include thiosulfates, thiocyanates, thioethers, thioureas, and a large amount of iodides. The thiosulfates are normally used, with ammonium thiosulfate being applicable most broadly. These thiosulfates may be preferably used in combination with thiocyanates, thioether compounds, thiourea or the like. As preservatives for the fixing bath or the blix bath there can be preferably used sulfites, bisulfites, carbonyl bisulfite adducts or sulfinic acid compounds as described in European Patent 294769A. Further, various aminopolycarboxylic acids or organic phosphonic acids can be added to the fixing bath or blix bath for the purpose of stabilizing the solution. In the present invention, the fixing solution or blix solution preferably comprises a compound having a pKa of 6.0 to 9.0, preferably imidazole such as imidazole, 1-methylimidazole, 1-ethylimidazole and 2-methylimidazole, in an amount of 0.1 to 10 mol/ℓ. The total desilvering time is preferably short so long as poor desilvering does not take place. The total desilvering time is preferably in the range of 1 to 3 minutes, more preferably 1 to 2 minutes. The desilvering temperature is in the range of 25 to 50°C, preferably 35 to 45°C. In this preferred temperature range, the desilvering rate can be improved, and the occurrence of stain after processing can be effectively inhibited. In the desilvering step, the agitation is preferably intensified as much as possible. 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 in the light-sensitive material as described in JP-A-62-183460 and JP-A-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 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, the blix bath or the 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 the 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 automatic developing machine to be used in the present invention is preferably equipped with a light-sensitive material conveying means as described in JP-A-60-191257, JP-A-60-191258, and JP-A-60-191259. As described in the above cited JP-A-60-191257, such a conveying means can remarkably reduce the amount of the processing solution carried over from a bath to its succeeding bath, exhibiting a high effect of inhibiting the deterioration of properties of the processing solution. This procedure is particularly effective for reducing the processing time at each step or for reducing the replenishment rate of the processing solution. It is usual that the thus desilvered silver halide color photographic materials of the invention are subjected to washing and/or stabilization. The quantity of water to be used in the washing can be selected from a broad range depending on the characteristics of the light-sensitive material (for example, the kind of couplers, etc.), the end use of the light-sensitive material, the temperature of the washing water, the number of washing tanks (number of stages), the replenishment system (e.g., counter-flow system or direct-flow system), and other various factors. Of these factors, the relationship between the number of washing tanks and the quantity of water in a multistage counter-flow system can be obtained according to the method described in "Journal of the Society of Motion Picture and Television Engineers", vol. 64, pp. 248-253 (May 1955). According to the multi-stage counter-flow system described in the above reference, although the requisite amount of water can be greatly reduced, bacteria would grow due to an increase in the retention time of water in the tank, and floating masses of bacteria stick to the light-sensitive material. In the present invention, in order to cope with this problem, the method of reducing calcium and magnesium ion concentrations described in JP-A-62-288838 can be used very effectively. Further, it is also effective to use isothiazolone compounds or thiabendazoles as described in JP-A-57-8542, chlorine type bactericides, e.g., chlorinated sodium isocyanurate, benzotriazole, and bactericides described by Hiroshi Horiguchi, "Bokinbobaizai no kagaku", Eisei Gijutsu Gakkai (ed.), "Biseibutsu no mekkin, sakkin, bobigijutsu", and Nippon Bokin Bobi Gakkai (ed.), "Bokin bobizai jiten" (1986). The washing water has a pH value of from 4 to 9, preferably from 5 to 8. The temperature of the water and the washing time can be selected from broad ranges depending on the characteristics and the end use of the light-sensitive material, but usually ranges from 15 to 45°C in temperature and from 20 seconds to 10 minutes in time, preferably from 25 to 40°C in temperature and from 30 seconds to 5 minutes in time. The light-sensitive material of the invention may be directly processed with a stabilizer in place of the washing step. For stabilization, any of the known techniques as described in JP-A-57-8543, JP-A-58-14834, and JP-A-60-220345 can be used. The aforesaid washing step may be followed by stabilization in some cases. For example, a stabilizing bath containing a dye stabilizer and a surface active agent is used as a final bath for the color light-sensitive materials for photography. Examples of such a dye stabilizer include aldehydes such as formalin and glutaraldehyde, N-methylol compounds, hexamethylenetetramine, and aldehyde-sulfurous acid adducts. The stabilizing bath may also contain various chelating agents or bactericides. The overflow accompanying the replenishment of the washing bath and/or stabilizing bath can be reused in other steps such as desilvering. In the processing using an automatic developing machine, if these processing solutions are concentrated due to evaporation, water may be preferably supplied to the system to compensate for the evaporation. The present silver halide color light-sensitive material may contain a color developing agent for the purpose of simplifying and expediting processing. Such a color developing agent is preferably used in the form of various precursors. Examples of such precursors include indoaniline compounds as described in U.S. Patent 3,342,597, Schiff's base type compounds as described in U.S. Patent 3,342,599, and Research Disclosure Nos. 14,850 and 15,159, and aldol compounds as described in Research Disclosure No. 13,924, metal complexes as described in U.S. Patent 3,719,492, and urethane compounds as described in JP-A-53-135628. The present silver halide color light-sensitive material may optionally comprise various 1-phenyl-3-pyrazolidones for the purpose of accelerating color development. Typical examples of such compounds are described in JP-A-56-64339, JP-A-57-144547, and JP-A-58-115438. In the present invention, the various processing solutions are used at a temperature of 10°C to 50°C. The standard temperature range is normally from 33°C to 38°C. However, a higher temperature range can be used to accelerate processing, thereby reducing the processing time. On the contrary, a lower temperature range can be used to improve the picture quality or the stability of the processing solutions. The present silver halide photographic material can also be applied to a heat-developable light-sensitive material as described in U.S. Patent 4,500,626, JP-A-60-133449, JP-A-59-218443, and JP-A-61-238056, and European Patent 210,660A2. The present invention will be further described in the following examples.

Furthermore, 1,2-benzisothiazoline-3-one, 2-phenoxyethanol, and phenethyl alcohol were incorporated in these layers as preservatives and antifungal agents. The term "monodisperse emulsion" as used herein means an "emulsion having a grain diameter variation coefficient of 20 % or less". Oil-1: Dibutyl phthalate Oil-2: Tricresyl phosphate Preparation of Specimens 102 to 118 Specimens 102 to 113 were prepared in the same manner as in Specimen 101 except that DIR compound Cpd-D incorporated in the 4th layer was replaced by Comparative Compound A, Comparative Compound B, Comparative Compound C, and Present Compounds I-(1), I-(2), I-(3), I-(4), I-(5), I-(12), I-(16), I-(19), I-(21), I-(25), I-(31), I-(32), I-(35), and I-(40) in equimolecular amounts, respectively. Specimens 101 to 118 thus obtained were cut into strips. These specimens were imagewise exposed to light through a red filter, and then uniformly exposed to light through a green filter. These specimens were then exposed to soft X-rays with widths of 20 µm and 1 mm for the evaluation of edge effect. These specimens were processed in a manner as described later. For the evaluation of interimage effect, the difference in magenta density between the portion in which the cyan color density is 2.0 and the portion in which the cyan color density is minimum was determined. For the measurement of edge effect, the density at 1-mm wide and 20-µm wide portions was determined through a red filter by means of a microdensitometer. For the evaluation of edge effect, the ratio of these measurements was determined. These specimens were then stored at a temperature of 40°C and a relative humidity of 80 % for 14 days. Another batch of these specimens were stored at room temperature for 14 days. These specimens were processed at the same time. These specimens were then compared for the maximum density of the cyan coloring layer. The results are set forth in Table 1. Table 1 shows that the use of the present DIR compound [I] provides great interimage and edge effects and a small drop in the maximum density (corresponding to a rise in fogging) during storage.

EXAMPLE 3 Preparation of Specimen 501 Preparation of emulsion of amorphous (thick twined crystal tablet) silver halide grains An aqueous solution of silver nitrate and an aqueous solution of potassium bromide were added to a solution of 25 g of potassium bromide, 24 g of potassium iodide, 1.9 g of potassium thiocyanate and 24 g of gelatin in 1 ℓ of water in a vessel at a temperature of 60°C with vigorous stirring in an ordinary ammonia process by a double jet process. Finally, an emulsion of relatively amorphous thick tabular silver bromoiodide grains with an iodine content of 8 mol % and an average grain diameter of 1.0 µm was prepared. To this emulsion was added Dye (a) in an amount of 230 mg/mol Ag and phenoxy ethanol in an amount of 50,000 ppm based on gelatin. The emulsion was then subjected to chemical sensitization (after-ripening) with sodium thiosulfate and chloroauric acid to obtain a light-sensitive silver bromoiodide emulsion (B). A light-sensitive silver bromoiodide emulsion (C) was prepared in the same manner as Emulsion (B) except that the content of potassium iodide in the starting solution was altered to 18 g and the temperature was altered to 40°C. The emulsion grains had an iodine content of 6 mol % and an average grain diameter of 0.6 µm. Furthermore, Emulsion D was prepared in the same manner as Emulsion C except that the material was not subjected to chemical sensitization.

These emulsions were dissolved in a mixture of tricresyl phosphate in the same amount and ethyl acetate in a 10-fold amount, and then subjected to dispersion in a homogenizer. Specimens 501 to 552 thus obtained were then evaluated for edge effect in the same manner as in Example 1. These specimens were processed at a temperature of 20°C in a small tank in accordance with D-76 processing method for 7 minutes. The results show that the specimens comprising DIR compounds exhibit a high edge effect and, among them, the specimens comprising DIR compounds used in the present invention particularly exhibit a high edge effect.
