Abstract: A photographic element comprising a support, a layer containing an image dye ligand or dye ligand forming material and a layer containing a dye mordant, wherein the mordant layer has associated therewith:(1) a polymer containing groups which form coordination complexes with metal ions; and(2) a source of metal ions.The polymer holds the metal ions in the vicinity of the dye mordant so that the metal ions can metallize the dye or dye forming material at the image receiving layer. These complexes, elements, and receiving elements are particularly useful in diffusion transfer processes. Novel polymers are also described.
