Wet metallization of acrylic resin articles

UV absorbing compounds, susceptible to free-radical polymerization, of the formula ##STR1## wherein R is alkyl having from 4 to 12 carbon atoms of which not more than 6 are present in a linear chain, and in particular 2-(2'-hydroxy-3'-methacrylamidomethyl-5'-tert-octylphenyl)benzotriazole, and polymers thereof.

UV-absorbing monomer and polymers thereof

A method for making multilayered synthetic resin bodies by the coextrusion of thermoplastic molding compounds wherein at least one of the layers in the extruded body is to be protected against UV light, which comprises extruding at least one layer from a thermoplastic molding compound that is formed entirely or predominantly of a copolymer formed between monomers comprising in their molecules groups or structures which, because of their characteristic absorption of ultraviolet light, provide protection against ultraviolet light, together with other, known, monomers.
