An improved nonglossy release formulation for use in a heat transferable laminate wherein an ink design image is transferred from a carrier support to an article by application of heat to the carrier support. The improved release enhances anchorage of the ink design image while maintaining the required degree of release during transfer to an article. The improved release prevents image distortion during heat transfer to the article and provides the transferred image with a transparent, nonglossy, abrasion and corrosion resistant protective coating. The improved release is composed of a paraffin wax and a binder adhesion-promoting resin composed of a mono-olefin/vinylacetate/acrylic acid terpolymer or a mono-olefin/ethyl acrylate copolymer.
