Abstract
Abstract An image-receiving material for silver salt diffusion transfer process having at least two layers wherein (I) a polymer layer containing diffusible compound, which can change the property of silver image formed in a binder layer containing silver deposition nuclei, and (II) the binder layer containing silver deposition nuclei on said polymer layer are provided on support, said polymer layer comprising at least one water insoluble hydrophilic polymer selected from the group consisting of homopolymers, copolymers and graft polymers of monoacrylates of polyhydric alcohols and homopolymers, copolymers and graft polymers of monomethacrylates of polyhydric alcohols.
