A printable material which includes a first, second, and third layer. The first layer has first and second surfaces. For example, the first layer may be a film or a cellulosic nonwoven web. The second layer overlays the first surface of the first layer. The second layer is composed of a first thermoplastic polymer having a melt flow rate of at least about 15 g/10 minutes at a temperature of 190.degree. C. and a load of 2.16 kg. The third layer overlays the second layer. The third layer includes a second thermoplastic polymer having a glass transition temperature equal to or greater than about 30.degree. C. The third layer also may include from about 1 to about 40 parts by weight, per 100 parts by weight of the second thermoplastic polymer, of a release agent. Desirably, the first and second layers will have smoothness values, as measured by a Sheffield Smoothness Tester, no greater than about 150 cc/minute and no greater than about 100 cc/minute, respectively. The third layer may contain up to about 150 parts by weight, per 100 parts by weight of the second thermoplastic polymer, of a plasticizer, and up to about 100 parts by weight, per 100 parts by weight of the second thermoplastic polymer, of a polymeric adhesion-transfer aid. The printable material is especially suitable for use as a dye diffusion thermal transfer printable heat transfer material.

[ What is claimed is:] [1.] A dye diffusion thermal transfer printable heat transfer material for receiving graphics or images produced by dye diffusion thermal transfer printing and for transferring said graphics or images to a substrate such as a fabric, said material comprising:a first layer having first and second surfaces;a second layer overlaying the first surface of said first layer, said second layer comprising a first thermoplastic polymer having a melt flow rate of at least about 15 g/10 minutes at a temperature of a 190.degree. C. and a load of 2.16 kg; anda third layer overlaying said second layer, said third layer having an affinity for diffusion dyes, said third layer comprising a second thermoplastic polymer that softens when exposed to heat and returns to its original condition when cooled to ambient temperature, said second thermoplastic polymer having a glass transition temperature equal to or greater than about 30.degree. C., said third layer further comprising a release agent for allowing said material to satisfactorily transfer said graphics or images to said substrate, wherein the release agent is a metal salt of a fatty acid.
