ABSTRACT:
Product and process for heat transfer labeling employing a release layer that is resistant to discoloration, cracking and crawling. The release layer is formed by a blend of oxidized and unoxidized polyethylenes in proportions that prevent objectionable discoloration and hold a superimposed design in situ in order to relieve stresses that could otherwise produce cracking and crawling during heat transfer labeling. Viscosity can be suitably controlled by the addition of a minority amount of paraffin.
