PURPOSE:To lower the resistance for drawing out of a photosensitive material of a broad size from a cassette by specifying the coefft. of dynamic friction of a back layer. CONSTITUTION:This product is formed by rolling the color photographic sensitive material for printing provided with silver halide emulsion layers on a base (A) and the coefft. of dynamic friction of the back layer (B) thereof is adjusted to 0.30-0.60. The reflection type base formed by coating the base paper with a thermoplastic resin, for example, alpha-olefin polymer and having <=180mum thickness is used for base A. Gelatin, etc, are usable for the back layer B on the thermoplastic resin layer of the back. A matting agent such as silica and a fluorine-contained anionic surface active agent, etc., are combined and may be added together with a hardener to the gelatin in order to lower the coefft. of friction. |
