摘要： 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.
