摘要： Described herein is a coating composition including one or more (meth)acrylic polymers including moieties of formula (I) *—C(═O)—O—CH2—Si(Ra)3−x(Rb)x  (I) where Ra=methoxy; Rb=an alkyl group containing 1 to 4 carbon atoms or an alkoxy group containing 1 to 4 carbon atoms; x is 0 or 1; and the asterisk * denotes the position at which the moiety of formula (I) is attached to the polymeric backbone of the (meth)acrylic polymer; further containing one or more catalysts of formula (II) H3C—C(Rc)(Rd)—C(═O)—O−M+  (II) where Rc and Rd=alkyl groups containing 1 to 6 carbon atoms, with the proviso that the sum of the number of carbon atoms in residues Rc and Rd ranges from 2 to 7, and M=for Li, K or Na, and further containing one or more aprotic organic solvents.
