A silver halide color photographic material is disclosed which has a silver halide color photographic material having at least one silver halide emulsion layer on a support, the silver halide emulsion layer containing at least one magenta coupler of formula (1):
wherein R1 is a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group, R2 is a monovalent group; R3 is an alkylene group; Y is a halogen atom or a hydroxy or alkyl group; Z is a group that can be eliminated by a coupling reaction with the oxidized product of a color developing agent; X is a direct bond or an alkylene group of 1 to 5 carbon atoms: m is 0 or an integer from 1 to 4; and n is 0 or an integer from 1 to 5 and a1 least one non-color forming phenolic compound.
本发明公开了一种卤化银彩色感光材料,该材料在支撑体上具有至少一个卤化银乳剂层,该卤化银乳剂层含有至少一个式(1)的品红耦合剂:
其中 R1 是取代或未取代的烷基或取代或未取代的芳基;R2 是单价基团;R3 是亚烷基;Y 是卤素原子或羟基或烷基;Z 是可通过与显色剂的氧化产物发生偶联反应而消除的基团;X 是直接键或 1 至 5 个碳原子的亚烷基:m 是 0 或 1 至 4 的整数;n 是 0 或 1 至 5 的整数,以及至少一种不形成颜色的酚类化合物。
