ABSTRACT:
The invention relates to a process of thermoforming thermoplastic substrates. More particularly the method of the invention relates to a method of thermoforming thermoplastic substrates wherein an integral coating is formed on the thermoplastic substrate that is resistant to removal of the coating. The novel coating method of the invention produces coated thermoplastic substrates wherein the coating is intimately bonded to the substrate. The coated substrates are hard, abrasion resistant, mold resistant, chemically resistant, and solvent resistant. The coating composition employs in a solvent base a pigment and a thermoplastic material compatible with the to be coated thermoplastic substrate. The thermoplastic material in cooperation with the pigment, solvent and other components of the coating composition after coating on the thermoplastic substrate, are heated to a thermoforming temperature and the thermoplastic material is intimately fused to the thermoplastic substrate surface.
