Abstract: Photographic elements, two-sheet diffusion transfer assemblages containing such elements, and dye image-receiving elements are described. The photographic element comprises a support, a neutralizing layer, a timing layer, a vinylidene chloride polymeric layer, a polymeric primer layer, and at least one silver halide emulsion layer having a dye image-providing material associated therewith. The vinylidene chloride polymeric layer and the polymeric primer layer prevent unwanted transfer of portions of the emulsion layer to a receiver when the receiver and photographic element are peeled apart. The polymeric primer layer can be either a particular ionic vinyl polymer or a particular ionic polyester.

Abstract: Two-sheet diffusion transfer assemblages and photographic elements are described which contain a primer layer located between a polymeric acid layer and a timing layer. The primer layer prevents unwanted transfer of portions of the emulsion layer to the receiver when the receiver and photographic element are peeled apart. The primer layer comprises:(a) a mixture of gelatin and cellulose nitrate, or(b) a mixture of an acrylic acid copolymer and a particular acrylic acid terpolymer, or(c) an acrylic acid copolymer as described herein.
