Abstract:
1. A layered sheet for application of a thermal coating to an image printed on porous media substrate, comprising: (a) an adhesive protective layer configured for flowing when the layered sheet is heated to an application temperature; (b) a carrier ribbon configured for carrying the adhesive protective layer, said carrier ribbon having a phase transition temperature (Tp) that is at least 20° C. greater than that of the adhesive protective layer, such that when the layered sheet is heated to the application temperature, the carrier ribbon has a coefficient of thermal expansion of less than 500 μm/m/° C. and substantially maintains its form; and (c) a release layer adhered between the adhesive protective layer and the carrier ribbon, wherein the release layer has a phase transition temperature (Tp) that is at least 2° C. greater than the adhesive protective layer, said release layer configured such that when the layered sheet is heated to the application temperature and the adhesive protective layer is applied to a porous media substrate, a first adhesion force between the porous media substrate and the adhesive protective layer is greater than a second adhesion force provided by the release layer.
