PROCESS FOR COATING POLYESTER FILMS, AND COATED FILMS

摘要

Oriented polyester film composites comprise, on at least one face surface of the polyester base, a primer coating adapted to enhance the adhesion of topcoats thereto, said adhesive primer coating comprising a modified copolymer produced by aqueous phase radical polymerization of at least one acrylic monomer in the presence of a water-soluble or water-dispersible copolyester containing a plurality of sulfonyloxy groups.
