    • The present invention relates to a solvent-based, pigmented coating agent which contains 0.02 to 0.75 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 R
      1 = C
      1 -C
      4 alkoxy, R
      2 = C
      1 -C
      4 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 (T
      g ) 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.
    • 本发明涉及一种溶剂型着色涂布剂,其含有相对于涂布剂总量为0.02〜0.75重量%的至少一种共聚物(A),其中共聚物(A)可以通过共聚 的烯属不饱和单体(a)在至少一种有机溶剂中的混合物,其中待聚合的单体(a)的混合物由(a1)10-60摩尔%的至少一种式(I ),其中R 1 = C 1 -C 4烷氧基,R 2 = C 1 -C 4烷基和m = 0-2,和(a2)40-90%摩尔的至少一种其它烯属不饱和单体,其中共聚物 (A)具有至少-30℃的玻璃化转变温度(T g)。 本发明还涉及一种使用涂层剂和多层涂层来制造多层涂层的方法。
