SILVER HALIDE COLOR PHOTOGRAPHIC SENSITIVE MATERIAL

摘要

PURPOSE:To improve the fading resistance of a formed cyan dye image in a dark place and/or in a light place by combinedly incorporating a specified 2-acylaminophenol cyan coupler, a specified phenol deriv. compound and a specified 2-phenylbenzotriazole compound into a silver halide emulsion layer. CONSTITUTION:At least one kind of cyan coupler represented by formula I (where R<1> is a diffusion resistant group, R<2> is 1-4C straight chain or branched alkyl and Z is H or a group eliminable by coupling), at least one kind of compound represented by formula II and at least one kind of compound represented by formula III are combinedly incorporated into a silver halide emulsion layer. The cyan coupler represented by the formula I is a so-called 2-acylaminophenol coupler and the amount of the coupler used is 0.05-2mol per 1mol silver halide in the silver halide emulsion layer. The compound represented by the formula II is a phenol deriv. compound known as an antioxidant and the preferred amount of the compound used is 1-200mol% of the total amount of the couplers in the silver halide emulsion layer. The compound represented by the formula III is a benzotriazole compound known as a UV absorber.
