PURPOSE:To prevent the formation of an unnecessary image arising from rubbing flaws and static electricity by incorporating a prescribed ratio of pulverized particles having a specific grain size into a back layer. CONSTITUTION:A silver halide emulsion layer and halation preventive layer are formed to one face of a base (e.g.: composite film prepd. by coating PE on both faces of a polyester film) and the back layer is formed on the other face. The pulverized particles (e.g.: pulverized inorg. particles of silica, etc., or org. particles of polymethyl methacrylate, etc.) having <=5mum average grain size are incorporated into the back layer at 0.1-10wt% by the weight of a binder (e.g.: gelatin). The reversed printing to obviate the generation of the unnecessary image is thereby permitted and the photosensitive material having high resolving power and high plate wear by a silver complex salt diffusion transfer method is obtd. |
