COLOR DIFFUSION TRANSFER PHOTOGRAPHIC UNIT WITH A COPOLYMERIC MORDANT LAYER CONTAINING QUATERNARY NITROGEN AND FLUORINE

摘要

A color diffusion transfer photographic unit comprising a silver halide photosensitive element and an image-receiv-ing element, which unit comprises a copolymer containing, as comonomers, a monomer having a quarternary nitrogen and a monomer having at least one fluorine atom. The use of this copolymer in this photographic unit gives excellent mordanting property without giving any bad effects on the photographic properties. The film forming property is excellent when the copolymer mordant is used singly or in combination with a binder. No deterioration is found in the image receiving property.
