ABSTRACT:
A photographic element comprises a support having thereon a layer containing a hydrophilic vehicle having dispersed therein a particulate polymeric material encapsulated with a chelating or already chelated polymer, said element, when the polymer is not already chelated, comprising a source of metal ions. The elements are useful in diffusion transfer processes, and particularly useful with chelating acid dyes or dye-forming materials to provide a metallized dye image.
