A silver halide photosensitive material is disclosed for color photography which comprises a phenol type cyan coupler having the formula:
wherein
X1 is -CN,-COOR1,-COR1,-SO2OR1,-SO2R1,
in which
R1 is an alkyl group or an aryl group and R is a hydrogen atom, an alkyl group or an aryl group;
X2 is a hydrogen atom, a halogen atom, a hydroxy group, a nitro group or a monovalent organic group;
Y, which is optionally present, is a non-metallic group which forms a 5- or 6-membered condensed ring as indicated by the dotted lines;
Z is a hydrogen atom or a group removable upon coupling with an oxidation product of a color developing agent;
Ball isa ballastgroup; and
n is 0 or and integer from 1 to 4 inclusive such that, when n is 2 or more, each X2 may be the same or different.
本发明公开了一种用于彩色摄影的卤化银感光材料,该材料包含一种苯酚型青色耦合剂,其化学式为
其中
X1 是-CN、-COOR1、-COR1、-SO2OR1、-SO2R1、
其中
R1 是烷基或芳基,R 是氢原子、烷基或芳基;
X2 是氢原子、卤素原子、羟基、硝基或一价有机基团;
Y 是一个非金属基团,如虚线所示,形成一个 5 或 6 元缩合环;
Z 是氢原子或与显色剂的氧化产物偶联后可去除的基团;
Ball 是镇流器基团
n 为 0 或 1 至 4 的整数,当 n 为 2 或 2 以上时,每个 X2 可以相同或不同。
