ABSTRACT:
The receptivity of shaped polymer articles (e.g., self-supporting films of polypropylene) to subsequently applied organic coatings is enhanced by exposure to an electrical discharge in the presence of a chlorocarbon or chlorofluorocarbon gas, thereby providing an extremely thin chlorine-containing surface layer in which the Cl:C ratio is inversely related to the distance from the face of the layer. Preferred embodiments of the invention include tape products in which the primed surface of the backing is coated with a pressure-sensitive adhesive or a low adhesion backsize.
