US 6,916,751 B1 · Heat transfer material having meltable layers separated by a release coating layer

Abstract

The present invention is directed to a heat transfer material containing a first (interior) meltable layer, a second (surface) meltable layer, and a release coating layer separating the first and second meltable layers. During a transfer process, the first (interior) meltable layer, release coating layer, and second (surface) meltable layer penetrate into the yarn interstices, or other undulations, of a given substrate to be coated. Only the second (surface) meltable layer transfers to the substrate, resulting in a thinner transfer coating compared to conventional coatings. The present invention is also directed to a method of making a printable heat transfer material and a method of forming an image-bearing coating on a surface of a substrate using the printable heat transfer material in a hot or cold peelable transfer process.

Dependent claims

A heat transfer material comprising:

a base substrate;
a first layer overlying the base substrate;
a second layer overlying the first layer, wherein the first and second layer are melt-flowable at a transfer temperature, the second layer further being transferable to a receiving substrate at the transfer temperature;
and
a release layer separating the first and second layers, wherein the release layer has essentially no tack at the transfer temperature.
