摘要：
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, subjecting the colloidal, elemental metal coated donor or receptor substrate to an electroless metal plating solution to provide a second elemental metal coating which is electrically conductive on said substrate.
