A silver halide color photographic material comprising a support having formed thereon at least one silver halide emulsion layer containing a pyrazoloazole series magenta coupler having at least one group expressed by the formula (S) below at a position other than the coupling active position.
wherein A represents a substituted or unsubstituted alkylene group, a substituted or unsubstituted cycloalkylene group, a substituted or unsubstituted arylene group, or a substituted or unsubstituted aralkylene group, in which in the main chain of said alkylene group, cycloalkylene group, arylene group, or aralkylene group, -O-, -S-, -CO-, -CO2-, -OCO-,
or -
may be contained; L represents
or
B represents a hydrogen atom or a substituted or unsubstituted alkyl or aryl group which does not contain therein -SO2-; n is 0 or 1; and R and R' each represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group. In the above, in the case that the pyrazoloazole series magenta coupler is a 1H-pyrazolo[5,1-c] [1,2,4]triazole derivative, A does not represent an aralkylene group containing an arylene group directly connected to L. The silver halide color photographic light-sensitive material has improved coloring properties.
一种卤化银彩色感光材料,它包括一个支撑体,支撑体上至少形成有一层卤化银乳剂,该层含有吡唑啉系列品红色偶联剂,该偶联剂在偶联活性位以外的位置上至少有一个由下式(S)表示的基团。
其中 A 代表取代或未取代的亚烷基、取代或未取代的环亚烷基、取代或未取代的亚芳基或取代或未取代的亚芳基,在所述亚烷基、环亚烷基、亚芳基或亚芳基的主链中,-O-、-S-、-CO-、-CO2-、-OCO-、
或
可包含; L 代表
或
B代表氢原子或取代或未取代的烷基或芳基,其中不包含-SO2-;n为0或1;R和R'各自代表氢原子、取代或未取代的烷基或取代或未取代的芳基。在上述中,在吡唑并唑系列品红色偶联剂是 1H-吡唑并[5,1-c] [1,2,4]triazole 衍生物的情况下,A 不代表含有与 L 直接连接的芳烷基的芳烷基。
