Abstract
Abstract PLASTIC PARTS ARE FORMED AGAINST AN ANODICALLY TREATED ALUMINUM SURFACE BY MOLDING, LAMINATING ETC., WHEREBY THE SURFACE OF THE FORMED PART AFTER REMOVAL OF OR SEPARATION FROM THE ALUMINUM HAS A HIGH ENERGY LEVEL AND IS RECEPTIVE TO ADHERENT COATING OF PAINT OR METAL PLATE. IN PARTICULAR, LAMINATES OF A THERMOPLASTIC RESIN AND A SACRIFICAL CLADDING OF ALUMINUM FOIL ARE PREPARED WHICH, AFTER SUBSEQUENT STRIPPING OF THE SACRIFICAL METAL CLADDING, EXHIBIT UNIQUE SURFACE PROPERTIES ENHANCING THE BONDING THERETO OF PAINTS, INKS AND PLATED METAL DEPOSITS.
