SUPPORTING BODY FOR PHOTOGRAPH

摘要

PURPOSE:To provide a photographic supporting body which shows excellent adhesion to a substrate or adhesion to a silver halide emulsion layer and little color change in a long-term storage or due to heat and can be produced in a simple process so that picture images of high resolution can be obtd. CONSTITUTION:This supporting body has a white reflecting layer on a substrate. The white reflecting layer is formed by applying a coating compsn. consisting of a white pigment and a binder. The white pigment essentially consists of titanium oxide. The binder essentially consists of vinyl chloride-vinyl acetate- maleic acid anhydride copolymers which are soluble in an org. solvent and have >=250 polymn. degree with (20wt.%-90wt.%): (5wt.%-50wt.%):(2wt.%-10wt.%) ratio of vinyl chloride: vinyl acetate:maleic acid anhydride.
