发明名称 Silver halide color photographic light-sensitive material
摘要 A silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, wherein the silver halide emulsion layer contains a silver halide emulsion which is spectrally sensitized by adding a spectral sensitizing dye prior to the completion of formation of silver halide particles and at least one kind of pyrazoloazole type magenta coupler represented by the following general formula (I): <IMAGE> (I) wherein R1 represents a hydrogen atom or a substituent; X represents a hydrogen atom or a group capable of being released upon a coupling reaction with an oxidation product of an aromatic primary amine developing agent; Za, Zb and Zc each represents a methine group, a substituted methine group, =N- or -NH-, one of the Za-Zb bond and the Zb-Zc bond being a double bond and the other being a single bond, and when the Zb-Zc bond is a carbon-carbon double bond, it may form a part of an aromatic ring; R1 or X may also form a polymer including a dimer or more; and when Za, Zb or Zc is a substituted methine group, the substituted methine group may form a polymer including a dimer or more. The silver halide color photographic light-sensitive material has a good color forming property and excellent stability during production and preservation, and provides color images having improved color reproducibility and image preservability.
