Abstract (en)
[origin: EP0327274A2] A light-sensitive silver halide photographic material comprising at least two light-sensitive silver halide emulsion layers containing diffusion-resistant couplers and at least one non-light-sensitive intermediate layer sandwiched between the light-sensitive silver halide emulsion layers provided on a support, wherein the non-light-sensitive intermediate layer contains a compound which deactivates the oxidized product of a color developing agent, the relative color formation speed ratio k1/k2 (lower color formation speed is defined as k1, and higher color formation speed as k2; when the color formation speeds are equal, either one may be applicable) between the diffusion-resistant couplers contained in the respective two light-sensitive silver halide emulsion layers adjacent to the non-light-sensitive intermediate layer is 0.25 </= k1/k2 </= 1, and the relationship of the k1/k2 to the ability Sc is represented by Formula (I): Sc.k1/k2 >/= 0.2 Formula (I) wherein Sc represents an abilty of the compound to deactivate the oxidized product of the color developing agent in the non-light-sensitive intermediate layer. According to the light-sensitive silver halide color photographic material of the present invention, the effect of preventing color turbidity and color reproducibility can be remarkably improved.
