ABSTRACT:
In a photographic monosheet material for the dye diffusion transfer process a temporary bond is adjusted between a first layer and a second layer by placing between said layers another layer of a graft polymer which is obtained by grafting a monomer containing double bonds capable of radical polymerization onto a hydrophilic linear basis polymer. The two layers are firmly bonded to each other but are easily separated, when the processing liquid is forced between them.
