发明名称 SILVER HALIDE COLOR PHOTOGRAPHIC SENSITIVE MATERIAL
摘要 PROBLEM TO BE SOLVED: To provide a silver halide color photographic sensitive material having high sensitivity, excellent graininess and excellent treatment stability. SOLUTION: This photographic material has photographic structural layers consisting of each at least one red photosensitive layer, green photosensitive layer, blue photosensitive layer and nonphotosensitive layer on one surface of a supporting body. In this material, the green photosensitive layer consists of three layers of high sensitivity layer, medium sensitivity layer and low sensitivity layer having different sensitivities. The high sensitivity layer contains at least two kinds of two-equiv. pyrazolone magenta coupler having different reaction rates with the oxide part of a color developing agent. The medium sensitivity layer and low sensitivity layer contain, as a single state, the two- equiv. pyrazolone magenta coupler having the lowest reaction rate of the two- equiv. pyrazolone magenta couplers included in the high sensitivity layer.
