Polyoxyalkylene overcoats for image-receiving elements

摘要

Diffusion transfer films and processes are disclosed wherein the processing composition includes a light reflecting pigment and an optical filter agent, and the image-receiving layer carries an overcoat comprising a polyoxyalkylene decolorizing agent hydrogen bonded with at least one other polymer and a salt of polyvinyl hydrogen phthalate, the overcoat layer being adapted to decolorize optical filter agent immediately adjacent the interface between the processing composition and the overcoat layer.
