PURPOSE:To provide the titled film for forming a magenta color with high saturation by controlling the color formation of a reddish dye to an arbitrary bluish side and capable of protecting the surface of photographic paper, obtained by containing a layer based on a specific metal compound and resin in a cover film. CONSTITUTION:A layer comprising a heat meltable adhesive obtained by dispersing or dissolving a compound of a metal selected from A, Mg, Ca and Sn in a resin solution based on resin in which a sublimable dye is easily deposited and diffused represented by polyester resin, epoxy resin and cellulose acetate resin is contained to obtain a cover film capable of diffusing and color devloping the dye when fused under heating to photographic paper formed by coating the single surface of a heat resistant substrate and controlling a magenta color. As the above-mentioned metal compound, substance capable of being dispersed or dissolved in the resin solution to form a transparent adhesive layer is used and, for example, a compound of an org. acid such as oleic acid and the above-mentioned metal is represented. |
