Claim 1
Independent Claim
197 words
An image-receiving element for color diffusion transfer photography for use with a photographic element containing at least one silver halide emulsion layer having incorporated therein a dye image-forming material that is soluble in alkaline solution and becomes diffusible upon development of the silver halide emulsion layer with an alkaline processing solution, and to which the dye image-forming material is imagewise transferred when the alkaline processing solution is spread between the image-receiving element and the photographic element; in which the image-receiving element comprises a support having at least one layer thereon, at least one layer of the image-receiving element being a hydrophilic image-receiving layer consisting essentially of polyvinyl alcohol or a mixture of at least 50 weight percent polyvinyl alcohol and one or more natural or other synthetic polymers and a polymethylol compound selected from the group of polymethylol compounds represented by the general formula (III) ##STR17## wherein R 7 , R 8 and R 9 each represents a hydrogen atom, a methylol group or an alkyl group and at least two of R 7 to R 9 are methylol groups and wherein said layer containing said polymethylol compound also contains a non-volatile acid as a cross-linking promoter.
