Silver halide color photographic material
摘要:
A conventional silver halide color photographic material is described, containing a coupler having a dye moiety having the maximum absorption wave length shifted to a short wave length by a linkage which is cleaved directly or through a timing group by a coupling reaction with the oxidation product of a developing agent and forming a compound or the precursor thereof (compound A) having a dye moiety having the maximum absorption wave length before shifting as the result of the above-described reaction and a compound capable of fixing the hue of the compound A at a long wave length and/or capable of immobilizing the compound A in the photographic layer.
