Abstract
Abstract Disclosed is a color photographic product having a patrone and a silver halide color photographic material rolled in said patrone, which said silver halide color photographic material comprises; a support having a thickness of 90 μm or less, a backing layer on a first face of said support, a silver halide emulsion layer and a protective layer on a second face of said support, wherein each outermost layer on said first and second face has a coefficient of kinetic friction of 0.33 or less with respect to a velvet attached to an opening of said patrone and said opening has a gap of 0.5 to 2.9 mm. A silver halide photographic light-sensitive material according to this invention is improved in flaw resistance, image sharpness and film abrasion resistance.
