An oriented polyester film coated on one or both sides with a crosslinked vinyl acetate polymer composition which renders the polyester film surface receptive to additional reprographic or matte coatings applied thereto, and to film containing the reclamation product of such coated film.

Polyester film primed with crosslinked vinyl acetate polymers

A prime coated oriented polyester film material is disclosed wherein the primer coating consists essentially of a crosslinked copolymer containing at least about 50% by weight of acrylic and/or methacrylic monomers and from about 1% to 15% by weight of a comonomer capable of inter-molecular crosslinking upon the application of heat, and from 0 to about 49% by weight of one or more halogen-free mono-ethylenically unsaturated monomers copolymerizable therewith. The priming layer may be applied to the polyester film at any suitable stage during manufacture of the film, i.e., before or during the stretching operations, and is crosslinked after application by means of heat. The resultant primed polyester film is found to provide excellent adhesion to many organic solvent based coatings subsequently applied thereto, and to be reclaimable when reprocessed during the manufacture of polyester film without giving rise to significant or intolerable discoloration or degradation of the film.

Polyester film primed with crosslinked acrylic polymers

A coated, oriented plastic film material is provided wherein the coating is applied in an aqueous medium comprising a water dispersible copolyester consisting essentially of the condensation product of components A, B, C and D or their polyester forming equivalents as follows:
