Filed:

May 3, 1984

Appl. No.:

6/606747

Inventors:

Friedrich H. H. Geurtsen - Holliston MA

International Classification:

B32B 706
C09J 702
C09J 704

US Classification:

428200

Abstract:

An improved 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. On transfer the release splits from the carrier and forms a protective coating over the transfered design. The improved release is coated onto the carrier as a solvent based-wax release. The release coating is then dried to evaporate the solvent contained therein. The improved release has the property that its constituents remain in solution down to temperatures approaching ambient temperature. Upon transfer, the release forms a protective coat which may be subjected to hot water. The improved release contains a montan wax, a rosin ester or hydrocarbon resin, a solvent, and ethylene-vinyl acetate copolymer having a low vinyl acetate content.

C09J 506

US Classification:

156235

Abstract:

A decorative laminate and method of transferring designs onto articles. The laminate is formed of a transfer substrate affixed to a support member. The transfer substrate is composed of a protective layer, an ink layer and a resinous coating layer. Optionally, a barrier layer is provided beteen the resinous layer and the ink layer. In many applications the protective coating layer may be omitted. The laminate is applied to an article using a heated silicone rubber transfer pad to which the transfer substrate adheres during the transfer process.

US Classification:

Abstract:

Apparatus for heat transfer labelling of articles using a resilient pad maintained at elevated temperatures. Decorative laminates affixed to a support member such as a web are fed to a heated platen. A resilient pad consisting of a silicone elastomer is pressed against the laminate at the heated platen, whereby the laminate adheres to the pad when it retracts from the platen. The heated pad is then pressed against an article to be labelled, to which the transfer substrate adheres in preference to the pad surface. The resilient pad is typically heated to a temperature above ambient temperature but lower than that of the heated platen. The pad is heated by repetitive contact with the platen, and additionally by an independent heater. The pad may include one or more interior heating elements, or an exterior radiant heater located adjacent the pad during periods between label transfers. This apparatus is well suited to the labelling of articles of a wide variety of sizes, shapes, and materials.
