Abstract
Abstract There is disclosed a silver halide color photographic material which comprises on a base at least one silver halide emulsion layer that is made up of at least one coupler and a silver halide grains of high silver-chloride and at least one-non-photosensitive layer containing at least one oil-soluble color-mixing inhibitor and at least homopolymer or copolymer represented by formula (I), with or without one of substantially non-diffusible oil-soluble compound represented by formula (II) or (III), and a method for forming an image by developing said silver halide color photographic material. The disclosure as described provides a color photographic material and a method for forming an image being excellent in image quality and in color separation and low in mixing of colors.
