The present invention relates to a solvent-based, pigmented coating agent having a solids content of at least 35 %, which contains 0.1 to 1.5 wt.% of at least one copolymer (A) in relation to the total amount of the coating agent, wherein copolymer (A) can be obtained by copolymerization of a mixture of olefinically unsaturated monomers (a) in at least one organic solvent, wherein the mixture of the monomers which is to be polymerized (a) consists of (a1) 10 to 60 mol% of at least one monomer of formula (I), in which R1 = C1-C4 alkoxy, R2 = C1-C4 alkyl and m = 0 to 2, and (a2) 40 to 90 mol% of at least one other olefinically unsaturated monomer, wherein copolymer (A) has a glass transition temperature (Tg) of at least -30 °C. The present invention also relates to a process for producing a multilayer coating using the coating agent and to the multilayer coatings. |
