Abstract
Substantially solvent-free multilayer articles characterized by excellent color retention and gloss retention, solvent resistance and recyclability comprise a substrate layer comprising a first material selected from the group consisting of a metal, ceramic, glass, a cellulosic material, a thermoset resin, and a thermoplastic resin, and a resinous coating layer which comprises at least one auxiliary color stabilizer additive and an arylate polymer comprising ester structural units derived from a resorcinol or alkylresorcinol isophthalate-terephthalate. An intermediate layer may also be present.
