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.
Claims9
A photographic element comprising a support having thereon a dye mordant containing-layer containing a hydrophilic vehicle having dispersed therein a non-metal chelating particulate polymeric material encapsulated with a member of the group consisting of a chelating polymer having associated therewith a source of metal ions and a metal chelated with a chelating polymer.
A photographic element comprising a support having thereon a dye mordant containing-layer containing a hydrophilic vehicle having dispersed therein a non-metal chelating particulate polymeric material encapsulated with a metal chelated with a chelating polymer.
A dye image-receiving element comprising a support having thereon a dye mordant containing-layer containing a hydrophilic vehicle having dispersed therein a non-metal chelating particulate polymeric material encapsulated with a member selected from the group consisting of a chelating polymer having associated therewith a source of metal ions and a metal chelated with a chelating polymer.
A photographic element comprising a dye mordant containing-layer containing a hydrophilic vehicle having dispersed therein a non-metal chelating particulate polymeric dye mordant encapsulated with a metal chelated with a chelating polymer and containing a dye or dye-forming material, imagewise.
A complex comprising metal coordinated to a dye and to the encapsulating polymer of a non-metal chelating particulate polymeric dye mordant encapsulated with a chelating polymer.
