Novel processes and compositions for producing expanded polystyrene articles coated with a durable, glossy, solvent-resistant integument, the compositions comprising a UV-curable oligomer, a UV-curable reactive diluent, and a photoinitiator, the compositions having a viscosity of from 800 to 20,000 cp. and the oligomer and diluent not being solvent for polystyrene, the compositions being cured by exposure to stated radiation to provide the durable coated articles, together with coated expanded polystyrene articles so produced.
