ABSTRACT:
A protective and decorative sheet material, such as a paint-coated film, which is bonded by an adhesive layer and vacuum thermoforming to an exterior automobile body panel as a substitute for spray painted finishes, can develop surface roughness when exposed to excessive heat for extended periods of time. This defect is unexpectedly reduced or eliminated by employing a foamed, pressure-sensitive adhesive layer.
