Abstract: 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.

Abstract: The present invention relates to an aqueous coating composition comprising at least one aqueous dispersion or solution (A) of at least one electrophoretically depositable binder and optionally of at least one crosslinking agent, and also at least one aqueous sol-gel composition (B), for at least partly coating an electrically conductive substrate with an electrocoat material, where the aqueous sol-gel composition (B) is obtainable by reaction of at least one starting compound suitable for preparing the sol-gel composition (B) with water, with hydrolysis and condensation of the at least one starting compound, to a method for producing the coating composition, to the use thereof for at least partly coating an electrically conductive substrate with an electrocoat material, to a method for at least partly coating an electrically conductive substrate with an electrocoat material by at least partial electrophoretic deposition of the coating composition on the substrate surface, to an electrically conductive substra
