Abstract
A process of heat transfer printing the surface of a filled polymeric article, wherein the filled polymeric article consists essentially of an inorganic filler, preferably alumina trihydrate, and a polymer with an affinity for disperse dyes, preferably polymethyl methacrylate. A desired design is printed onto a carrier using sublimable disperse dyes. The filled polymeric article is preheated, the carrier supporting sublimable disperse dye is placed in intimate contact with the preheated article, and sufficient heat is applied to cause the dye to sublime, then diffuse into the surface of the article.
