摘要:
A silver halide color photographic light-sensitive material comprising a support having coated thereon at least one silver halide emulsion layer, the color photographic light-sensitive material having at least one layer containing at least one 2-equivalent magenta coupler of the 5-pyrazolone type represented by the following general formula (I):
wherein W represents a phenyl group substituted with at least one substituent selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, an alkoxycarbonyl group and a cyano group; Y represents an acylamino group or an anilino group; and Z represents a group capable of being released upon coupling, and at least one compound represented by the following general formula (II):
wherein R' and R Z , which may be the same or different, each represents a hydrogen atom, an alkyl group or an aryl group, provided that both R' and R' do not represent hydrogen atoms atthe same time; Z' represents a methine group, a substituted methine group orthe group-N=; and Q represents an atomic group which contains a nitrogen atom, a sulfur atom or an oxygen atom and is necessary to form a 5-membered ora 6-membered heterocyclic ring together with the group-C=Z 1 -. The silver halide color photographic light-sensitive material can provide an excellent magenta color image without the occurrence of stain, even when the color photographic material is processed in a processing solution under the running condition.
