ABSTRACT:
A photographic element comprises a support having thereon a layer containing a copolymer comprising a vinylimidazole in association with metal ions. The metal forms a novel complex with the polymer and photographic elements comprising these materials are useful in diffusion transfer processes, and particularly useful with metal-coordinating dyes such as chelating dyes or dye-forming materials to provide a metallized dye image.
