发明名称 SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL HAVING GOOD SPECTRAL ABSORPTION CHARACTERISTICS OF FORMED COLOR MATTER
摘要 PURPOSE:To improve the color reproducibility of the titled material by incorpo rating at least one of a specified yellow coupler and at least one of a specified compd. in at least one layer of a silver halide emulsion layer. CONSTITUTION:At least one of the yellow coupler shown by formula I and at least one of the compd. shown by formula II are incorporated in at least one layer of the silver halide emulsion layer. In formulas I and II, R1 is halogen atom. or alkoxy group, R2 is hydrogen atom. or a group capable of substituting to a benzene ring, R3 is a monovalent org. residual group, Z1 is a group capable of releasing by a reaction with the oxidant of a color developing main agent, R<1>-R<3> are each an aliphatic or an aromatic group, (l)-(n) are each 0 or 1. Thus, the titled material having the improved color reproducibility is obtd.
