ABSTRACT:
Elements for use in a photographic diffusion transfer process comprising a sheet-like support having a polymeric acid neutralizing layer bonded thereto, wherein said polymeric acid layer is formed from a composition including a crosslinking agent that effects temporary crosslinks within said polymeric layer to promote resistance to aqueous interference during film unit assembly, but which readily hydrolyze under processing conditions so as to accommodate swelling of the polymeric layer in the presence of alkali processing composition.
