ABSTRACT:
A protective coating composition is applied to the decorated and/or printed surface of a foamed plastic substrate to provide abrasion resistance, high gloss, and lubricity. Preferably, the composition is comprised of a water-based mixture of polyurethane resin and emulsified polyethylene resin, the latter being emulsified with an ionic or non-ionic emulsifier. The composition is especially useful for application over the exterior of foamed plastic surfaces which have been decorated and/or printed with printing inks prior to fabrication of the material into plastic articles.
