Abstract
Abstract silver halide color photographic material is described comprising on a support thereof at least one emulsion layer containing silver halide grains of high chloride content wherein said silver halide grains have on the surface thereof a layer mainly composed of silver bromide and 90 to 99.5 mol % of the silver halide of said grains is silver chloride and 0.5 to 10 mol % of the silver halide is silver bromide.
