ABSTRACT OF THE DISCLOSURE Acrylate copolymers containing amino and hydroxyl groups useful as additives for aqueous cationic coating systems for preventing surface flaws and for improving the adhesion of further coats, in particular of PVC-containing coating materials, are described. In addition to amino groups which can be neutralized with acids, the acrylate copolymers contain a selected quantity of hydroxyl groups originating from monoesters of (meth)acrylic acid with diols. The additives are added in a quantity from 0.5 to 5.0% by weight, calculated on solids and relative to the solids content of the binder in a coating cystem.
