A photographic assembly for the photographic diffusion transfer process is provided wherein a stripping layer is used consisting of a graft copolymer of gelatin which has been substantially fully reacted with a dicarboxylic acid anhydride selected from phthalic anhydrides, succinic anhydrides, glutaric anhydrides and a monomer of a vinyl ester, a vinyl ether, an acrylic ester, an acrylic ether, a methacrylic ester or a methacrylic ether or a mixture thereof. These stripping layers exhibit good dry adhesion to the emulsion layer and to the mordant layer and moderate wet adhesion.
