| 摘要 |
The invention relates to an aqueous coating composition containing (A) at least one organic binder that can be dispersed in water and contains cationic groups, and (B) 0.05-10 wt. %, in relation to the solid body content of the aqueous coating composition, of a water-dilutable vinylpyrrolidone copolymer. Said vinylpyrrolidone copolymer (B) contains vinylpyrrolidone monomer units and vinylacetate monomer units in a molar ratio of 0.3:0.7-0.7:0.3, preferably 0.4:0.6-0.6:0.4 and has an average molecular weight of less than 200.000 g/mol.
