- / - VARNISH AND ITS USE FOR PRODUCING VARNISH COATINGS AND COLOR- AND/OR EFFECT-PRODUCING MULTI-LAYER COATINGS

摘要

The present invention relates to the use of copolymer (A) in varnishes used to produce varnish coatings and color- and / or effect-generating multilayer coatings. The copolymer (A) comprises at least one of the formula (I) R ¹ R ² C = CR ³ R ⁴ which is different from a) at least one olefinically unsaturated monomer and b) olefinically unsaturated monomer (a) in an aqueous medium. Obtained by radical polymerization of an olefinically unsaturated monomer, wherein the residues R ¹ , R ² , R ³ and R ⁴ are independently hydrogen or substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl , Aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl group, provided that at least two of the variables R ¹ , R ² , R ³ and R ⁴ are optionally substituted aryl, arylalkyl or arylcycloalkyl groups, In particular, the substituted or unsubstituted aryl group is represented.
