Abstract
A silver halide color photographic material which comprises a support having thereon at least two silver halide light-sensitive layers having essentially the same color sensitivity but different speeds and a light-insensitive layer positioned adjacent to the highest-speed layer of said light-sensitive layers and containing a compound which reacts with the oxidation products of a color developing agent to form a diffusible development restraining compound or a precursor thereof. The photographic material provides a color image having excellent graininess and color reproduction and has excellent characteristics of development processing.
