ABSTRACT:
Two-sheet diffusion transfer assemblages, photographic elements and dye image-receiving elements are described wherein an overcoat layer is present on the photographic element or the dye image-receiving element superposed thereon. The overcoat layer comprises either silica or an ionic polyester in a hydrophilic colloid which prevents spontaneous delamination during the lamination period, yet permits satisfactory peel-apart afterwards.
