ABSTRACT:
An improved release coating for heat transferable laminate and improved method for curing the release coating for heat transferable laminates wherein an ink design layer is transferred from a carrier web onto an article such as a plastic or glass container upon application of heat and pressure. The improved release coating does not contain wax components but exhibits release properties similar to wax based formulations. The improved release contains U-V curable components which are cured by exposure to ultraviolet light after the laminate containing the ink design, is transferred to a receiving article. The heat transferable laminate preferably includes a barrier layer intermediate the release layer and ink design layer. The barrier layer also contains U-V curable components. The barrier layer is cured by exposure to ultraviolet radiation during formation of the laminate structure and prior to transfer of the laminate to a receiving article. The improved release formulation upon curing by ultraviolet radiation produces a hard, glossy, optically clear protective layer exhibiting enhanced resistance to abrasion, scuffing and solvent attack.
