Abstract

A method is provided for making a thermoformable composite involving the treatment of at least one of the major surfaces of a thermoplastic substrate, such as a sheet, with a solventless ultra-violet (UV) curable organic resin, followed by the UV-curing of the resin. The cured resin provides an adherent decorative and/or protective coating having desirable biaxial elongation characteristics.
