A paint composition with improved hiding power includes water, a film-forming polymer, pigments, and a plurality of hollow glass spheres dispersed in the paint composition. Advantageously, the hollow glass spheres encapsulate air voids in coatings formed from the paint composition.

An inherently printable polymeric material is provided. The polymeric material includes a homogenous mixture of a thermoplastic polymer with a Tg of about 30-80 C., a cyclic olefin copolymer, an ionomer of ethylene and methacrylic acid, and a thermoplastic rubber. The polymeric material can be printed without requiring printing receptive layers or treatments. The polymeric material can be thermoformed, yet retains its printability even after thermoforming.
