Abstract
A protective and decorative sheet material, such as a paint-coated film, which is bonded by an adhesive layer and vacuum thermoforming to a substrate, can develop surface roughness when exposed to heat for extended periods of time. This defect is unexpectedly reduced or eliminated by raising the surface energy of the substrate and roughening the surface of the substrate within certain limits, prior to application of the sheet material.
