PURPOSE:To obtain a photosensitive material for the silver salt diffusion transfer process prevented from sticking, and hardly foaming in developing a processing compsn. by adding a matting agent contg. a specified amt. of particles specified in size to the uppermost layer of the photosensitive material. CONSTITUTION:The matting agent to be added contains particles having >=10mum diameter in an amt. of 7-30 volume % of the total particles. The matting agent is an org. or inorg. powder, preferably, particle diameters of 1-25mum, especially, 2-20mum. It is, preferably, embodied by dispersible vinyl polymer like polymethyl methacrylate, cellulose acetate-propionate, or starch. As the inorg. matting agent, silver halide, strontium sulfate, calcium carbonate, silica, magnesia, and titania, etc., are, preferably, used. |
