A heat transferable laminate wherein an ink design image is transferred from a carrier support to a receiving article, typically a plastic bottle or container, by application of heat to the carrier. The heat transferable laminate is composed of a carrier support, release coating, an ink design layer, and improved adhesive coating thereon. The improved adhesive coating is prepared from a mix containing an adhesive component and a film-forming component blended in a miscible solvent. The solvent evaporates upon drying the coating. The adhesive component contains a blend of vinylacetate/ethylene copolymer and a styrene-based resin. The adhesive coating is equally suitable as an adhesive on heat transferable laminates for transfer to a wide variety of plastic articles including polyolefins, polystyrene, and polyvinylchloride. The improved adhesive coating obviates a long standing prior art need to pretreat polyolefin receiving articles as by preflaming prior to applying the heat transferable laminate thereto. The improved adhesive formulation exhibits a wide array of advantageous properties for the intended application. These properties include uniform coatability on wax or nonwax release and on ink at low coating thickness, highly sensitive heat activatable tackification, maintenance of film integrity during heat transfer of the laminate to the receiving article, high bonding strength, and abrasion resistence. |
