The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a novel silver halide color photographic light-sensitive material in which interaction between a DIR compound and a hydroquinone compound is prevented. It is already known that a silver halide photographic light-sensitive material contains a compound that can release a development inhibitor upon reaction with the oxidation product of a color developing agent (this is called a DIR compound). The active site of a photographic coupler is substituted with a group that can act as a development inhibitor when released, and when a coupling reaction occurs, this substituent diffuses and affects the development of silver halide, causing image graininess. and sharpness, which can substantially improve overall color reproduction. In this regard, ``Photographic Science Engineering''
(Photographic Science and Engineering) No. 13
It is described in the paper "Development - Inhibitor Release Singing Coupler" published in Vol. 74 (1969). DIR compounds include U.S. Patent No. 3,623,245;
Specifications of the same No. 3928041 and JP-A-49-77635
Disclosures are known in publications such as No. 49-104630 and No. 52-36028. On the other hand, alkyl-substituted hydroquinone is used in the intermediate layer in order to prevent unnecessary fogging and contamination due to air oxidation of the developing agent, and to prevent color mixing due to diffusion of oxidized products of the developing agent into adjacent layers during development. This is well known. These hydroquinone compounds include US Pat. No. 2,732,300;
Although disclosed in the specifications of No. 3700453 and No. 2728659 and Japanese Patent Application Laid-open No. 15438/1983,
These alkyl-substituted hydroquinone compounds,
In a silver halide photographic light-sensitive material containing a DIR compound, when added to a layer containing the DIR compound or an adjacent layer, it interacts with the DIR compound, decomposes the DIR compound, and acts to inhibit development. It has the disadvantage that the group is liberated and the photographic sensitivity decreases. Furthermore, recently, with the trend toward higher sensitivity of silver halide color photographic materials, two-equivalent couplers with high color development efficiency have been used, which tends to cause unnecessary fog.To prevent this, hydroquinone is used as an antifoggant. As the usage amount of hydroquinone compounds increases, the above-mentioned drawbacks increase significantly, making it difficult to use hydroquinone compounds. Therefore, the first object of the present invention is to provide a silver halide color photographic photosensitive material that does not interact with a DIR compound even when a hydroquinone compound is used in a hydrophilic colloid layer containing a DIR compound or in a hydrophilic colloid layer adjacent thereto. The goal is to provide materials. A second object of the present invention is to provide a silver halide color photographic light-sensitive material that can obtain a good antifogging effect without causing a decrease in sensitivity. It is an object of the present invention to incorporate a DIR compound that couples with the oxidation product of an aromatic primary amine developing agent to release a development inhibitor but does not form a dye into a silver halide emulsion layer or a hydrophilic compound adjacent to said emulsion layer. In the silver halide color photographic light-sensitive material containing the DIR compound in the color colloid layer, one or more sulfonic acid groups or salts thereof, or carboxylic acid groups or This was achieved by incorporating a hydroquinone compound containing a salt thereof and having a substituent having a total of 8 or more carbon atoms on an aromatic nucleus into a silver halide color photographic light-sensitive material. Further, as an advantage of the present invention, since the hydroquinone of the present invention is water-soluble, it can be easily dispersed in water, and a dispersion step using a high boiling point solvent or the like can be omitted. The DIR compound used in the present invention is represented by the following general formula [][][]. In the formula, X 1 represents a hydrogen atom or a halogen atom (chlorine atom, bromine atom, etc.). On the other hand, the group represented by Y is a group that, when reacting with the oxidation product of the color developing agent, separates to form an aryl mercapto compound, a heterocyclic mercapto compound, or a triazole compound having a development inhibiting effect. Examples of the heterocyclic mercapto compound include mercaptotetrazole compounds (for example, 1
-Phenyl-5-mercaptotetrazole, 1-
nitrophenyl-5-mercaptotetrazole,
1-naphthyl-5-mercaptotetrazole, etc.), mercaptothiazole-based compounds (e.g., 2-mercaptobenzthiazole, 2-mercaptonaphthothiazole, etc.), mercaptooxadiazole-based compounds (e.g., 5-mercapto-1,2,4 -oxadiazole, etc.), mercaptopyrimidine-based compounds (e.g., 4-mercaptopyrimidine, etc.), mercaptothiadiazole-based compounds (e.g., 2-mercapto-5-amino-1,3,4-thiadiazole, etc.), mercaptotriazine-based compounds, Examples include compounds (such as 2-mercapto-1,3,5-triazine) and mercaptotriazole compounds (such as 3-mercapto-1,2,4-triazole). Examples of arylmercapto compounds include mercaptobenzene compounds (for example, 1-mercapto-2
-benzoic acid, 1-mercapto-2-nitrobenzene, 1-mercapto-3-heptadecanoylaminobenzene, etc.). Examples of triazole compounds include benzotriazole compounds bonded at the 1- or 2-position (for example, 5-methylbenzotriazole, 5-
Bromobenzotriazole, 5-octadecanamidobenzotriazole, 5-benzyloxybenzotriazole, etc.) are useful. Z represents a group of nonmetallic atoms required to form a carbocycle or a heterocycle, such as a 5-membered or 6-membered saturated or unsaturated carbocycle, and this carbocycle forms a condensed ring at an appropriate position. Specific examples include monocyclic or condensed rings such as cyclopentanone ring, cyclohexanone ring, indanone ring, benzindanone ring, and the carbocyclic ring has at least one substituted or unsubstituted alkyl group, It represents an aryl group, a nitro group, a cyano group, an alkoxy group, an aryloxy group, an acylamino group, a sulfonamide group, a sulfamoyl group, a carbamoyl group, an acyloxy group, a heterocyclic group, and the like. Specific examples of these include alkyl groups (e.g. tert-butyl group, octyl group, dodecyl group, etc.), aryl groups (e.g. phenyl group, tolyl group, etc.), and alkoxy groups (e.g. octyloxy group, dodecyloxy group, etc.). , aryloxy groups (e.g., phenoxy group, p-tert-butylphenoxy group, naphthoxy group, etc.), acylamino groups (e.g., acetamido group, butylamide group, etc.), sulfonamide groups (e.g.,

æãããïŒ[Table] From the table above, when only the DIR compound (D-1) of the present invention is used, there is an effect of reducing Fog, but a softening effect due to a decrease in Dmax is observed (Sample-2). It can be seen that the sample (4) using only the hydroquinone compound of the present invention has an antistain effect equivalent to that of the conventional hydroquinone compound sample (3), with little loss in sensitivity. On the other hand, when examining the interaction, the test material (5) that used a conventional alkyl-substituted hydroquinone compound in combination with the DIR compound of the present invention showed an interaction immediately and was desensitized at 60°C.
After 2 days at 80% RH, the interaction is further promoted and significant desensitization is observed. On the other hand, sample (6) using a combination of the DIR compound of the present invention and the hydroquinone compound of the present invention has performance that combines the effects of hydroquinone and the DIR compound, and shows no desensitization even after 2 days at 60% and 80%RH. The fact that no interaction was observed and same-day performance was maintained indicates that there is no interaction. Also, when looking at the interaction based on the DIR effect, there is no interaction as sample (6) using the hydroquinone compound of the present invention has the same DIR effect as sample (2) using only the DIR compound. I understand that. On the other hand, it can be seen that in sample (5), the conventional hydroquinone compound and the DIR compound of the present invention interact, resulting in significant desensitization. Here, the DIR effect is (1-D T )Ã of the same-day sample.
The value is expressed as 100, indicating that there is no desensitization of S1 , and the larger the value, the greater the effect. Here D
T represents the density of samples 2 to 6 at the same exposure amount as the exposure amount for sample (1) with a density of 1.0. Example 2 A composition as shown in the table below was emulsified and dispersed on a transparent triacetate film support in the same manner as in Example-1, and added to a silver halide emulsion having the same composition as in Example-1 to obtain the same coated silver amount. , Sample 7 made into a coating film,
I got 8, 9, 10, 11. (However, sample No. 10 was prepared by adding the hydroquinone of the present invention as a 1% aqueous solution.)
