ABSTRACT:
A layer for preventing sticking of thermal image-forming materials to thermal printheads during thermal printing. The layer comprises polymeric material having a non-cyclic, substantially completely saturated hydrocarbon backbone, said backbone having substantially only hydrogen atoms and methyl groups attached to randomly positioned carbon atoms thereon, with no more than one methyl gorup attached to any one backbone carbon atom. Application of the anti-stick layer to the substrate is facilitated by the solubility of the polymeric material in commonly used organic solvents, thereby allowing very thin layers of the coating to be applied in the form of dilute solutions.
