Abstract

PURPOSE:To prevent variation of photographic performance due to the lapse of time during storage, especially, increase of fog by specifying a coupler to be added to a silver halide emulsion layer and an inhibitor to be added to a photographic constituent layer. CONSTITUTION:The silver halide photogrpahic sensitive material has the photographic constituent layer comprising at least one silver halide emulsion layer and a nonphotosensitive hydrophilic colloidal layer on a support, and at least one of the silver halide emulsion layers contains at least one of couplers to be allowed to release a diffusive development inhibitor or its precursor by the coupling reaction with the oxidation product of a developing agent, and at least one of the photographic constituent layers contains as the inhibitor the compound or its water-soluble salt represented by the formula shown on the right in which X is -OH or -NH2; each of R1 and R2 is H, halogen, an aliphatic group, or an aromatic group, and each may link to each other to form a hetero ring together with the N atom; Y is a group substitutable on the benzene ring; and (n) is an integer of 0-4. As a result, variation of photographic performance due to the lapse of time during storage can be made less probable and, especially, increase of fog can be prevented.

A high-sensitivity microparticulation technique Sj that harmonizes the contradictory properties of A degree and graininess has also been developed, and has been shown to be effective as a photosensitive material for general use, medical use, and printing. However, on the other hand, fi! Small 7 of photosensitive materials for shadows
With the introduction of formatted formats (for example, 110 film, disk film, etc.), enlarged prints from 77' film have suffered from image roughness (graininess) and deterioration of sharpness, which have seriously degraded print image quality. is also true. Conventionally, various techniques for improving sharpness are known, and among them, many methods using couplers that can release a development inhibitor or its precursor during a coupling reaction with an oxidized developing agent, so-called DIR couplers, have been disclosed.

It is known that However, diffusive DIR has the drawback that it is susceptible to fluctuations in photographic performance during storage over time, and in particular, fog tends to increase, and it has not reached the level of 1g4.
