Abstract
Photographic elements, diffusion transfer assemblages and processes are described wherein a polymeric vehicle is employed in a metallizable dye image-receiving layer, a layer adjacent thereto or both. The polymeric vehicle comprises a cross-linked polymer derived from recurring units of an acrylamide, a 1-vinyl-2-pyrrolidone or a 2-hydroxyethyl acrylate and a cross-linkable monomer.
