ABSTRACT:
Distortion and chemically resistant heat transfer materials formed by a mixture of at least two interspersed polymers. One of the polymers is a film-forming, multi-aromatic ring condensation product, preferably a saturated aromatic, acid-based polyester. This polymer is reinforced by a second polymer which preferably contains bulky ring structures, such as polymerized rosin esters, but may be essentially linear, for example an ethylene-vinyl acetate copolymer. The materials may be used as a protective and brightener coating for labels, which are heat activated to transfer them from a carrier to a final substrate such as the face of a package. The labels thus coated exhibit improved resistance to adverse chemicals such as alcohols, oils and detergents. The materials may also be used to provide distortion and chemically resistant inks, and distortion and chemically resistant adhesives.
