The copolymer of the vinylidene chloride, vinyl chloride, vinyl acetate and maleic anhyride is preferably the copolymer of 29W80mol% vinylidene chloride, 20W80mol% vinyl chloride, 5W20mol% vinyl acetate, and 0.1W5mol% maleic anhydride. The generation of the film exfoliation of the silver halide photosensitive layer, fogging and spots by development processing is thereby obviated and the image having the good reproducibility of hues, gradations, etc., and excellent sharpness is obtd.
