Abstract
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.

In a heat transferable laminate of the type including a carrier support and a heat transferable substrate comprising a release layer in contact with the carrier support, and an ink design layer, said substrate being transferable from the carrier support to a receiving article upon application of heat to the carrier while said receiving article contacts the transferable substrate, an improved release layer, comprising:
- a wax component;
- and
- a binder resin comprising a thermoplastic acrylic-based terpolymer resin selected from the group consisting of a monoolefin/vinyl acetate/acrylic acid terpolymer and a monoolefin/allyl acetate/acrylic acid terpolymer, the improved release having a drop melting point between about 85.degree. C. to 135.degree. C., permitting transfer at between about 300.degree. F. and 600.degree. F. in less than 2 seconds and resolidifying after transfer to provide a transparent, matte, nonglossy, protective coating.
In a heat transferable laminate of the type including a carrier support and a heat transferable substrate comprising a release layer in contact with the carrier support, and an ink design layer, said substrate transferable from the carrier support to a receiving article upon application of heat to the carrier while said receiving article contacts the transferable substrate, an improved release layer comprising:
- a paraffin wax;
- and
- a binder resin comprising a mono-olefin/ethyl acrylate copolymer, the improved release having a drop melting point between about 85.degree. C. to 135.degree. C., permitting transfer of said heat transferable substrate at transfer temperatures between about 300.degree. F. to 600.degree. F. in a period less than about 2 seconds, and resolidifying after transfer to provide a transparent, matte, nonglossy, protective coating.
In a heat transferable laminate of the type including a carrier support and a heat transferable substrate comprising a release layer in contact with the carrier support, and an ink design layer, said substrate being transferable from the carrier support to a receiving article upon application of heat to the carrier while said receiving article contacts the transferable substrate, an improved release layer, comprising:
- a paraffin wax component;
- and
- a binder resin comprising a thermoplastic acrylic-based terpolymer selected from the group consisting of a monoolefin/vinyl acetate/carboxylic acid terpolymer and a monoolefin/allyl acetate/carboxylic acid terpolymer, wherein the carboxylic acid is a monounsaturated carboxylic acid having a carbon content between about C.sub.3 and C.sub.5, the improved release having a drop melting point between about 85.degree. C. to 135.degree. C., permitting transfer at between about 300.degree. F. and 600.degree. F. in less than 2 seconds and resolidifying after transfer to provide a transparent, matte, nonglossy, protective coating.
