<p>1. Coagulating agents for lacquers, waxes ant coating compositions, containing water-soluble copolymers of a) monomers containing acid groups ("S-monomers") corresponding to the following general formula see diagramm : EP0163108,P6,F1 in which : R**1 and R**2, which may be the same or different represent hydrogen or linear or branched C1 -C3 alkyl groups and A may be a hydroxy radical or an iminoalkane sulfonic acid residue, in which the alkylene group may be branched or unbranched and may contain from 1 to 6 carbon atoms, and b) monomers containing amino groups ("A-monomers") corresponding to the following general formula see diagramm : EP0163108,P6,F2 in which : R**3 and R**4, which may be the same or different, represent hydrogen or linear or branched C1 -C3 alkyl groups and R**5 and R**6, which may be the same or different represent C1 or C2 alkyl groups, B is oxygen or an -NH- groupe, the alkylene radical characterized by (Cn H2n ) may be linear or branche and n is an integer of from 1 to 6, and c) hydrophobicizing monomers ("H-monomers") corresponding to the following general formula see diagramm : EP0163108,P6,F3 in which : R**7 and R**8, which may be the same or different represent hydrogen or linear or branched C1 -C3 alkyl groups and R**9 is a linear or branched C1 -C6 alkyl group, or styrene, the molar ratio of the S-monomers from 2 : 1 to 1 : 2 and the molar ratio of the H-monomers to the sum of the other two monomers being greater than or equal to 1 : 20</p> |
