ABSTRACT:
A substantially dimensionally stable, calendered vinyl film construction having good chemical resistance and outdoor durability is disclosed. The film comprises a calendered vinyl film, an adhesive having high creep and shrinkage resistance on one side thereof, and release paper bonded to the adhesive on the side remote from the vinyl film. It is useful as a substrate for markings and decals on the exterior surfaces of vehicles and other structures. The calendered film which comprises polyvinyl chloride, a plasticizer or plasticizers and heat and ultraviolet light stabilizers is heat and pressure stabilized after calendering. Release paper is then coated with a layer of high creep and shrink resistant adhesive by reverse roll coating, and the release paper/adhesive composite is dried and is laminated to the film at a laminating nip.
