| abstract |
Plastics surfaces are provided with a highly adherent, water- and ethanol-resistant coating, as a clear varnish or pigmented, by painting with an aqueous dispersion of (meth)acrylate polymers built up from 20 to 90 % by weight of alkyl or cycloalkyl acrylates and/or methacrylates having 1 to 10 carbon atoms in the ester radical and from 80 to 10 % by weight of acrylates and/or methacrylates containing aromatic groups as the ester radical, or containing aromatic groups in the ester radical, and small amounts of further monomers. n<??>The copolymers are preferably emulsion polymers and are built up in a plurality of phases, for example in accordance with the core/shell model. |
