Abstract
Abstract Varnishing plastic surfaces with a clear or pigmented aqueous dispersion of a (meth)acrylate copolymer of (a) 20 to 90% by weight of acrylic and/or methacrylic acid alkyl or cycloalkyl esters with 1 to 10 carbon atoms in the ester group; (b) 80 to 10% by weight of acrylic and/or methacrylic acid esters with aromatic groups as the ester group or containing aromatic groups in the ester group; and (c) optionally, small quantities of other monomers, results in the formation of a firmly adhering, water and alcohol resistant finish. The copolymers are preferably emulsion polymers and are synthesized as multiple-phase polymers according to the core-shell model.
