ABSTRACT:
An improved 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 transfers with the ink design layer and forms an optically clear protective coating over the transferred ink design layer. The transferred release coating upon resolidification has an exceedingly high optical clarity, with no hazing, spotting, or halo discernible over the transferred ink design layer. The improved release coating incorporates a tackifying resin in a wax base. The wax base includes a montan wax and a crystalline wax such as paraffin wax. The wax base may also include a microcrystalline wax component. The tackifying resin is a transparent hydrogenated hydrocarbon resin.
