Abstract
Abstract A heat transfer print sheet comprising a base sheet, printing on said base sheet, a coating overlying the printed surface of the base sheet, said printing being capable of transferring through said coating upon application of heat and pressure, said coating preventing the heat transfer print sheet from adhering to a substrate to which the printing is transferred, said transferred printing permeating into the interior of said substrate to provide a wear resistant print thereon, said printing being transparent to light and thereby enhanced in color by any background color on said substrate.
