Smear and scratch resistant thermally transferable printing ribbons and methods of making the same

摘要

Smear and scratch resistant thermally transferable printing ribbons and methods of making the same consisting of elongated backing elements having thermally transferable printing media adhered to one side thereof. The thermally transferable printing media preferably consists of two layers, a sub coat layer and a print layer, and is capable of being transferred to paper, or some other print receiving media, by conventional thermal transfer printing equipment. The use of a silicon compound and/or ethylene bisstearamide and/or micronized polyethylene in the sub coat layer provides enhanced smear and scratch resistance in thermally transferred printed images while maintaining the advantage of low thermal energy print transfer.
