ABSTRACT:
A printable heat transfer material having cold release properties, which material includes a flexible first layer having first and second surfaces. The first layer typically will be a film or a cellulosic nonwoven web. A second layer overlays the first surface of the first layer and includes a thermoplastic polymer, such as a hard acrylic polymer or a poly(vinyl acetate). A third layer overlays the second layer and includes a thermoplastic polymer which melts in a range of from about 65.degree. C. to about 180.degree. C. The first layer may be a cellulosic nonwoven web, such as a latex-impregnated paper. The thermoplastic polymer of which the second layer is composed may have a glass transition temperature of at least about 25.degree. C. The second layer also may include an effective amount of a release-enhancing additive, such as a divalent metal ion salt of a fatty acid, a polyethylene glycol, or a mixture thereof. The third layer may include a film-forming binder, which binder may include a powdered thermoplastic polymer. For an ink jet printable heat transfer material, a fourth layer may overlay the third layer, which fourth layer includes a film-forming binder and a powdered thermoplastic polymer. If desired, a fifth layer may overlay the second layer, thereby being located between the second layer and the third layer. The fifth layer may include a film-forming binder which melts in a range of from about 65.degree. C. to about 180.degree. C.
