摘要:
The present invention relates to a (meth)acrylate polymer for preparing a coating composition, where the (meth)acrylate polymer has a weight-average molecular weight in the range from 10 000 to 60 000 g/mol and the (meth)acrylate polymer comprises 0.5 to 40% by weight of units derived from (meth)acrylic monomers which in the alkyl radical have at least one double bond and 8 to 40 carbon atoms, 0.1 to 10% by weight of units derived from monomers containing acid groups, and 50 to 99.4% by weight of units derived from (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical that have no double bonds or heteroatoms in the alkyl radical, and these (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical are selected such that a polymer composed of these (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical has a glass transition temperature of at least 40° C., based in each case on the weight of the (meth)acrylate polymer.The present invention further relates to a coating material comprising the stated polymer, and to a method of producing a coating. The present invention additionally describes a coated article comprising a coating obtainable by the method.
