  • Receiving elements for image transfer film units
    Patent number: 4282305
    Abstract: An image dye receiving element comprises a support having thereon in order:(1) a layer comprising a source of metal ions and a binder therefor; and(2) a dye image receiving layer comprising a polymer containing heterocyclic tertiary groups.The receiving element can be used in an image transfer film unit which contains a dye ligand or dye ligand former and the film unit is stable to metal ion wandering and the resulting metallized dye image is stable to fading.

  • Catalytic activation of cobalt complex imaging by cobalt sulfide
    Patent number: 4188217
    Abstract: An imaging system and process wherein an element comprising a cobalt complex-developer redox system is catalyzed by cobalt sulfide. The cobalt sulfide can be imagewise produced by exposing a photoreducible cobalt complex in the presence of a thioamide, or it can be uniformly distributed and either masked in an imagewise fashion, or reacted with imagewise distributed color developing agent.
