Abstract:
A method of making a printable heat transfer material comprising:providing a flexible first layer having first and second surfaces and selected from the group consisting of films and cellulosic nonwoven webs;applying a second layer onto the first surface of the first layer, wherein the second layer has essentially no tack at transfer temperatures of about 177.degree. C. and comprises a thermoplastic polymer having a solubility parameter of at least about 19 (Mpa).sup.1/2, and a glass transition temperature of at least about 0.degree. C.; andapplying a third layer onto the second layer, wherein the third layer comprises a thermoplastic polymer which melts in a range of from about 65.degree. C. to about 180.degree. C. and has a solubility parameter less than about 19 (Mpa).sup.1/2 ; wherein the second and third layers are adapted to provide the printable heat transfer material with cold release properties.
