ABSTRACT:
A process for thermal transfer printing on plastic films incorporating a coating composition is provided. The process includes providing plastic film having a coating composition including a binder of a polymer and/or copoylmer of carboxylic acid containing vinylic unsaturation, at least one finely divided particulate filler, and a surface active agent. A thermographic element such as a ribbon which includes a dye layer is then heated in the form of an image to be printed onto the plastic film, with the heating causing the dye layer to melt in the form of the image. The plastic film coated with the coating composition is contacted with the thermographic ribbon, and the dye layer is transferred from the ribbon to the plastic film. Such thermal transfer printing on coated plastic films provides for a multitude of uses such as plastic labels for outdoor use.
