Abstract: An imaging film donor sheet comprising a substrate, a controlled release/adhesive layer and a vapor-deposited colorant layer, wherein the deposited colorant layer exhibit a discernible microstructure, preferably a columnar microstructure. A matching receptor sheet is provided. A method of preparing the donor sheet as well as a method of imaging is provided.

Abstract: The present invention provides a process for thermal mass transfer of metallic images, the process comprising the steps of(a) providing(1) a toner fluid dispersion comprising electrostatically charged, colloidal elemental metal particles dispersed in an electrically nonconductive organic carrier liquid and an amount of a soluble surfactant effective to charge and stabilize said dispersion,(2) a dielectric or photoconductive substrate, and(3) a thermoplastic receptor substrate,(b) electrophoretically depositing the charged colloidal elemental metal particles of the toner fluid in a uniform or imagewise fashion on the dielectric or photoconductive substrate using standard electrographic techniques to provide a donor substrate bearing an electrically nonconductive, colloidal, elemental metal coating thereon;(c) transferring, by application of energy, said metal coating from said donor substrate to said thermoplastic receptor substrate, to provide a metallic image on said receptor substrate,(d) optionally, subjec

Abstract: The present invention relates to toner fluid dispersions comprising electrostatically charged colloidal elemental metal particles dispersed in nonconductive organic liquid media of low dielectric constant and containing a charge-inducing surfactant. In other aspects, processes are disclosed for electrophoretically depositing the colloidal elemental metal particles of the toner fluid to produce nonconductive, continuous coatings or patterns and methods of enhancing the coatings or patterns to make them electrically conductive.

Abstract: A novel donor construction is used for thermal mass transfer imaging applications. The donor constructions are coated from pigment dispersions which are flushed in solutions containing a chlorinated wax. Because of near refractive index matching to the coloring pigments and the low cohesive strength of the chlorinated wax, this novel thermal mass transfer system is characterized by low transfer energy requirements and high transparency in the transferred images.

Abstract: A thermal imaging transfer process and donor sheet are described. The donor sheet comprises a layer of particulate colorant/binder on a substrate. Essentially individual particles are transferred during imaging to provide a high resolution image.

Abstract: The surface properties of solid substrates are improved by the formation of discrete sites of inorganic materials on one surface of the substrate.

Abstract: An article having a primed surface or improved electric charge transfer properties is disclosed. The surface has discrete sites of inorganic materials thereon.

Abstract: Imaging processes where charge images are transferred from one surface to another are improved by the presence of conductivity sites on at least one of the surfaces, said sites being discrete, composed of an inorganic material, and having an average length between 1.0 and 20 nm. Between 0.1 and 40% of either the photoconductive surface or dielectric layer may be covered with electrically conductive sites.
