Abstract:
1. A method of applying an image to a receptor element which comprises the steps of: (i) imaging a heat-setting label sheet, said imaging being provided by a laser printer or a laser copier, wherein said heat-setting label sheet comprises: a pressure sensitive adhesive layer comprising at least one of a polyester, acrylic polymer, or copolymer blend, said polyester, acrylic polymer, or copolymer blend having a glass transition temperature (Tg) of less than 0° C.; and an Adhesion Layer comprising a thermoplastic polymer which melts in the range of 50–250° C., a wax which melts in the range of 50–250° C., or combinations thereof; a barrier layer coated on the support, said barrier layer comprising (1) a vinyl acetate with a Tg in the range of −10° C. to 100° C.; (2) a thermoplastic polymer having essentially no tack at transfer temperatures, a solubility parameter of at least 19 (Mpa) (ii) peeling said image and Adhesion Layer from said support, wherein said peeling occurs without water, heat, or chemical aids; (iii) positioning the Adhesion Layer against said receptor element; and either (iv) applying heat to the Adhesion Layer by placing a sheet of paper or protective film in between the Adhesion Layer and heating device to protect the label from damage caused by the heating device during heating, or applying heat from the side of the receptor element that does not contain the image and Adhesion Layer, wherein said heat is applied with a heat press or an iron.
