<p>PURPOSE:To improve the mordant layer and decrease white turbidity when wetted with water-base phorographic processing liquid, in lamination type color diffusion transfer process photographic elements, by using specific polymer mordant dye and acid processing gelatine in the mordant layer. CONSTITUTION:A polymer mordant dye having the unit of formula (R1 to R3 are alkyl of which total number of C is more than 12; X(-) is anion) and perferably having the molecular weight of about 10,000 to 50,000, and a acid processing gelatine are dissolved in a mixed solution of water and ethanol or the like, and is spread and dried on the transparent support body. It is preferable that the polyme mordant dye may be used at 20 to 80 wt.% and 0.5 to 8 g/m<2> rate. Above this is provided a photosensitive halogenated silver emulsion layer combined with color image donor substance, and a photosensitive sheet is combined with a cover sheet.</p> |
