A silver halide color photographic light-sensitive material containing novel pyrazolotriazole type magenta couler is disclosed. The coupler is reprsented by the following Formula I:
wherein R1 is a primary alkyl, a secondary-alkyl group or a tertiary-alkyl group; R2 is an aralkyl group represented by the following Formula II; and X is a substituent capable of splitting off upon reaction with the oxdation product of a color developing agent;
wherein R3, R4, R5 and R6, are each a hydrogen atom or an alkyl group, provided that at least one of R3 and R4 is an alkyl group when R1 is a primary alkyl group; R7 is a group having a -COOM group, in which M is a hydrogen atom or a cation; and t is 0 or 1. The light-sensitive material is excel-lent in color foeming efficiency and color reproducibility.
本发明公开了一种含有新型
吡唑三唑类品红色耦合剂的卤化
银彩色感光材料。该耦合剂由下式 I 表示:
其中 R1 是伯烷基、仲烷基或叔烷基;R2 是由下式 II 表示的芳烷基;X 是在与
显色剂的氧化产物反应时能够分裂的取代基;
其中 R3、R4、R5 和 R6 各为氢原子或烷基,但当 R1 为伯烷基时,R3 和 R4 中至少有一个为烷基;R7 为具有 -COOM 基团的基团,其中 M 为氢原子或阳离子;以及 t 为 0 或 1。这种光敏材料在显色效率和色彩再现性方面表现出色。
