Description: FIELD OF THE INVENTION The present invention relates to a silver halide photographic material which is excellent in image quality such as graininess, and more particularly, to a silver halide photographic material containing a compound capable of releasing a development inhibitor upon oxidation in a development processing step. BACKGROUND OF THE INVENTION A series of compounds which are capable of releasing a photographically useful group via an oxidation reduction reaction have hitherto been known. For instance, as hydroquinone derivatives capable of releasing a development inhibitor, compounds as described in U.S. Patents 3,379,529, 3,620,746, 4,144,071, 4,377,634, 4,332,878 and 3,930,863 are exemplified. Also, as catechol derivatives, compounds as described in British Patent 1,400,149 are known. EP-A-204175 and JP-A-61-233741 both disclose silver halide photographic material comprising compounds which contain groups at the position of R₃ of formula (I) of the present invention. These groups are released upon the reaction with an oxidation product of a developing agent. As described in the above-mentioned patents, these hitherto known compounds are employed for various purposes depending on the kind of photographic light-sensitive material in which they are present. Among others, in color photographic light-sensitive materials, hydroquinones capable of releasing a development inhibitor exhibit effective properties for the purpose of improving sharpness, graininess and color reproducibility. However, these known compounds are still insufficient to meet stringent requirements and to improve various kinds of photographic properties. Therefore, further improvents have been desired. More specifically, the above described known compounds are apt to be oxidized and immediately release a development inhibitor at the time of development. However, they have the fatal defect that they are extremly unstable when incorporated into photographic light-sensitive materials and are readily oxidized by air during storage of the photographic light-sensitive materials. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a photographic light-sensitive material excellent instability during storage, sharpness, graininess and color reproducibility. Other objects of the present invention will become apparent from the following detailed description and examples. These objects of the present invention can be accomplished by a silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer, characterized in that the silver halide photographic material contains at least one compound represented by the following general formula (I): wherein R₁ and R₂ each represents a hydrogen atom or a group capable of being cleaved with an alkali; R₃ represents an aromatic group or a heterocyclic group, the group represented by R₃ is unable to be released upon the reaction with an oxidation product of a developing agent; R₄ represents a group capable of substituting on the benzene ring; n represents an integer from 0 to 2; and DI when released represents a development inhibitor or a precursor thereof, when n represents 2, two R₄'s may be the same or different, an when any two substituents of R₁, R₂ and R₄ are present on the adjacent positions, they may be divalent groups and connected with each other to form a cyclic structure(e.g., 5- or 6-membered cyclic structure).

Silver halide grains in the silver halide emulsion may have a regular crystal structure, for example, a cubic, octahedral or tetradecahedral structure, etc., an irregular crystal structure, for example, a spherical or tabular structure, etc., a crystal defect, for example, a twin plane, etc., or caqn be a composite structure thereof. The particle size of the silver halide may be varied and includes from fine grains having about 0.2 micron or smaller than 0.2 micron diameter to large grains having up to about a 10 micron diameter as projected area. Further, a polydispersed emulsion and a monodispersed emulsion may be used. The silver halide photographicemulsion used in the present invention can be prepared using known methods, for example, those as described in Research Disclosure , No. 17643 (December, 1978), pages 22 to 23, "I. Emulsion Preparation and Types" and ibid ., No. 18716 (November, 1979), page 648, P. Glafkides, Chimie et Physique Photographique , Paul Montel (1967), G.F. Duffin, Photographic Emulsion Chemistry , The Focal Press (1966), and V.L. Zelikman et al., Making and Coating Photographic Emulsion , The Focal Press (1964), etc. Monodispersed emulsions as described in U.S. Patents 3,574,628 and 3,655,394, British Patent 1,413,748, etc., are preferably used in the present invention. Further, tabular silver halide grains having an aspect ratio of about 5 or more than 5 can be employed in the present invention. The tabular grains may be easily prepared by the method as described in Gutoff, Photographic Science and Engineering , Vol. 14, pages 248 to 257 (1970), U.S. Patents 4,434,226, 4,414,310, 4,433,048 and 4,439,520, British Patent 2,112,157, etc. The crystal structure of the silver halide grains may be uniform or may be composed of different halide compositions between the inner portion and the outer portion, or may have a stratified structure. Alternatively, silver halides emulsions in which silver halide grains having different compositions may be connected to each other by an epitaxial junction or by any suitable compound other than silver halide such as silver thiocyanate, lead oxide, etc. Moreover, a mixture of grains having different crystal structures may be used. The silver halide emulsions used in the present invention are usually formed with physical ripening, chemical ripening and spectral sensitization. Various kinds of additives which can be employed in these steps are described in Research Disclosure , No. 17643 (December, 1978) and ibid ., No. 18716 (November, 1979) and relevant items are summarized in the table now shown. Further, known photographic additives which can be used in the present invention are also described in the above literature and relevant items are summarized in the table below. The compounds represented by general formula (I) and the couplers which can be used in the photographic light-sensitive material of the present invention can be introduced into the photographic light-sensitive material according to various known dispersing methods. Suitable examples of organic solvent having a high boiling point which can be employed in an oil droplet-in-water type dispersing method are described in U.S. Patent 2,322,027, etc. Processes and effects of latex dispersing methods and specific examples of latexes for loading are described, for example, in U.S. Patent 4,199,363, West German Patent Application (OLS) Nos. 2,541,274 and 2,541,230, etc. Suitable supports which can be used in the present invention are described, for example, in Research Disclosure , No. 17643, page 28 and Research Disclosure , No. 18716, page 647, right column to page 648, left column, as mentioned above. The color photographic light-sensitive material according to the present invention can be subjected to development processing in a conventional manner as described in Research Disclosure , No. 17643, pages 28 to 29 and Research Disclosure , No. 18716, page 651, left column to right column, as mentioned above. After development, bleach-fixing or fixing, the silver halide color photographic material according to the present invention is usually subjected to a water washing process and/or a stabilizing process. The amount of water to be used in the water washing step can be set in a broad range, in accordance with the characteristic of the photographic light-sensitive material which is processed (for example, depending upon the raw material components, such as coupler, etc.) or the use of the material, as well as the temperature of the washing water, the number of the washing tanks (the number of the washing stages), the replenishment system (countercurrent or parallelcurrent) and other various kinds of conditions. Among the above conditions, the relation between the number of the washing tanks and the amount of the washing water in a multi-stage countercurrent system can be obtained by the method described in Journal of the Society of Motion Picture and Television Engineers , Vol. 64, pages 248 to 253 (May, 1955). According to the multi-stage countercurrent system described in the above publication, the amount of water to be used in the water washing step can be greatly reduced, however, bacteria would propagate in the tank because of the need to prolong the staying time of washing water in the tank so that some floating substances formed would adhere to the photographic material which is processed. This is a troublesome problem. As the means for preventing the propagation of bacteria, the method described in Japanese Patent Application (OPI) No. 288838/87, where calcium and magnesium are reduced, can extremely effectively be utilized in the practice of the present invention. Also, the isothiazolone compounds and the thiabendazoles described in Japanese Patent Application (OPI) No. 8542/82, the chlorine series bactericides such as the chlorinated sodium isocyanurates, benzotriazoles and other various bactericides or fungicides described in H. Horiguchi, Chemistry of Bactericides and Fungicides , Bactericidal and Fungicidal Technique to Microorganism , edited by Sanitary Technical Association (Japan) and Encyclopedia of Bactericides and Fungicides , edited by Japan Bactericidal and Fungicidal Association can also be used. The pH of the washing water in the processing of the photographic material in accordance with the present invention is from 4 to 9, preferably 5 to 8. The temperature and time for the washing can be set variously in accordance with the characteristics of the photographic material which is processed, the use thereof, etc., and in general, it is from 15 to 45°C and 20 seconds to 10 minutes, and preferably from 25 to 40°C and 30 seconds to 5 minutes. Further, the photographic material of the present invention can directly be processed with a stabilizer solution without taking the water washing step. When such the stabilization step is directly carried out, any and every known method, for example, the methods described in Japanese Patent Application (OPI) Nos. 8543/82, 14834/83, 184343/84, 220345/85, 238832/85, 239784/85, 239749/85, 4054/86 and 118749/86, etc. can be utilized. A stabilizer solution containing 1-hydroxyehtylidene-1,1-diphosphonic acid, 5-chloro-2-methyl-4-isothiazoline-3-one, bismuth compounds or ammonium compounds can preferably be used in the above described stabilization step. After the water washing step described above, further stabilization step may be carried out. In this case, a stabilizer solution containing formalin and a surfactant, which is usually used as a final processing solution for a color photographic material for photography. When the photographic light-sensitive material of the present invention is a black-and-white silver halide photographic material, it can be subjected to development processing according to methods as described in Research Disclosure , Vol. 176, No. 17643, pages 28 to 29 and Research Disclosure , Vol. 187, No. 18716, page 651, left column to right column.
