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 temperautre of 190 DEG 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 tmeperature equal to or greater than about 30 DEG 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. |
