    (54) Light-sensitive silver halide photographic material


    (57) 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.
