Abstract
Abstract A metallized laminate and process of manufacture wherein a metallic layer or underlying ink layer appears in a pattern on the laminate. The method in a specific embodiment involves the steps of forming a laminate by coating a heat stable release coat onto a carrier sheet; coating an ink layer in a pattern on the heat stable release coating so that at least portions of the release coat remain uncovered with ink, and applying a metallic layer over the release coat so that at least a portion of the metallic layer is in direct contact with and adheres directly to the release coat. Portions of the metallic layer may be removed by an etchant. A heat activatable adhesive layer is applied over the metallic layer. The laminate so formed is heat transferable from the carrier sheet to an article.

Claim 9
Independent Claim
219 words
A method of transferring a design to an article comprising the steps of: (a) coating a heat stable release coating onto a carrier sheet, said carrier sheet comprising polyethylene terephthalate and said heat stable release coating comprising polyethersulfone; (b) coating an ink layer in a pattern on the heat stable release coating so that at least portions of the release coating remain uncovered with ink; (c) applying a metallic layer over the release coating so that at least a portion of the metallic layer is in direct contact with and adheres directly to the release coating; (d) applying an etchant resistant coating over portions of said metallic layer so that other portions of the metallic layer remain exposed, said etchant resistant coating selected from the group consisting of polyethersulfone, polyamide lacquer and polyvinylchloride; (e) applying an etchant coating in contact with said etchant resistant coating and said exposed metallic portions, said etchant coating removing said exposed metallic portions upon contact therewith; (f) applying a heat activatable adhesive layer over the metallic layer, said release layer, ink layer and metallic layer forming a transferable laminate; (g) transferring said transferable laminate from the carrier to an article at heat transfer temperatures in the range from 200° F. to 500° F., the transferred laminate on the article having a bright metallic appearance.
