Abstract:
An aqueous coating composition comprising (A) at least one water-dispersible organic binder containing cationic groups and (B) 0.05%-10% by weight, based on the solids content of the aqueous coating composition, of a water-thinnable vinylpyrrolidone copolymer, where the vinylpyrrolidone copolymer (B) contains vinylpyrrolidone monomer units and vinyl acetate monomer units in a molar ratio of 0.3:0.7 to 0.7:0.3, preferably of 0.4:0.6 to 0.6:0.4 and possesses a weight-average molecular weight of less than 200 000 g/mol.
