ABSTRACT:
An adhesive-coated thermoplastic film is stretched and bonded to a three-dimensional substrate by vacuum thermoforming at a lower than normal temperature, at which the film has an elastic modulus of at least 10.sup.9 dynes/cm.sup.2, followed by moderate heat treatment of the resulting laminated article. The procedure is especially useful in avoiding air entrapment and peel-back in the thermoforming of a paint-coated film on exterior body panels for automobiles.
