发明名称 SILVER HALIDE PHOTOSENSITIVE MATERIAL
摘要 PURPOSE:To enhance sensitivity, color formation performance, image sharpness, resistances to light, heat, and humidity, etc., by incorporating a specified phenolic cyan dye image-forming coupler in a silver halide emulsion layer. CONSTITUTION:An intended silver halide color photosensitive material is obtained by incorporating in at least one of silver halide emulsion layers a phenolic cyan coupler having at the 2-position of the phenol ring, a phenylureido group having -SO2R, R being alkenyl or alkynyl, at the 4-position, H or a group releasable in the coupling reaction with the oxidized product of a color developing agent, and at the 5-position, an acylamino group. This cyan coupler can be easily synthesized in accordance with the reaction course represented by reaction equations I , R1 being a ballast group, such as optionally substd. alkyl or the like, and the coupler is embodied by formulae II, III, etc.
