    摘要： A substantially protein free receiving layer for use in a photographic diffusion transfer process comprises silver precipitants and a colloid binder comprising at least 90 percent, by weight, of a copolymer of (1) about 90 percent to about 98 percent, by weight, of at least one haloalkyl methacrylate in which the haloalkyl group contains 1 to 10 carbon atoms with (2) about 2 percent to about 10 percent, by weight, of an unsaturated polymerizable organic acid having three to six carbon atoms. The layer can also contain toning and/or processing compounds.
