Abstract:
A transfer printing process comprising:(a) applying to a flat or tridimensional surface a composite film having thereon a drawing made with sublimable colors, said composite film consisting of: (1) a polymeric film as the composite base capable of resisting decomposition at the sublimation temperature, and having a thickness in the range of 6 to 100 microns; (2) an aluminum layer having a thickness in the range of 50-400 Ã¥ deposited on the polymeric film and exhibiting an optical density of 1.5-3.0, and (3) the drawing impressed on the aluminum layer, and (b) transferring said drawing made with sublimable colors by heating the composite and the receiving support at temperatures of 170Â° C.-210Â° C., at which color sublimation occurs.
