Abstract: The present invention provides a method of forming an electroluminescent circuit by screen printing. The method according to the invention includes screen printing a rear electrode pattern on a substrate, which is preferably a polyester sheet, screen printing a dielectric layer over the rear electrode pattern, screen printing a front electrode pattern on the dielectric layer, and screen printing a phosphor layer over the front electrode layer. The rear electrode pattern preferably includes a solid layer disposed upon the substrate and the front electrode pattern preferably includes a plurality of opaque lines separated by spaces. In an alternative embodiment, the method according to the invention includes screen printing the phosphor layer on the substrate, screen printing the front electrode pattern on the phosphor layer, screen printing the dielectric layer over the front electrode pattern, and screen printing the rear electrode pattern over the dielectric layer.

Abstract: A process for coating and transfer printing sheet metal for producing a decorated section of metal that is especially suited for use in harsh environments. The process yields a section of metal having a transfer printed layer comprising a thermoset coating material and a protective overcoat layer formed of substantially clear thermoset coating material. The process includes the steps of coating a section of metal with a pigmented thermosetting coating material, curing the coating material to form a base coat layer, transfer printing the base coat layer to form a transfer printed layer, applying a protective clear thermosetting coating material over the transfer printed layer, and curing the protective clear thermosetting coating material so as to provide a clear protective overcoat layer covering the transfer printed layer.
