The present invention relates to a silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, which contains at least one nondiffusible pyrazolo(1,5-b)(1,2,4)-triazole magenta coupler represented by the following general formula (I) in at least one of the silver halide emulsion layers in order to acquire high color formability and to produce a dye image excellent in hue:
wherein R1 represents an alkyl group; R2 and R3 each represents a hydrogen atom or an alkyl group, provided that both are not a hydrogen atom; R4 represents an alkyl group, an alkoxy group or a halogen atom; L represents an alkylene group; m represents an integer of 0 to 5; n represents an integer of 0 to 5, and when n is 2 or more, the R4.'s may be different from one another; and X represents a halogen atom.
本发明涉及一种卤化银彩色感光材料,该材料包括一个支撑体,支撑体上至少有一层卤化银乳剂层,在至少一层卤化银乳剂层中含有至少一种由下通式(I)表示的不可扩散吡唑(1,5-b)(1,2,4)-三唑洋红耦合剂,以获得高显色性并产生色调优异的染料图像:
其中 R1 代表烷基;R2 和 R3 各自代表氢原子或烷基,但两者都不是氢原子;R4 代表烷基、烷氧基或卤素原子;L 代表亚烷基;m 代表 0 至 5 的整数;n 代表 0 至 5 的整数,当 n 为 2 或 2 以上时,R4.
