2420/US3490 ABSTRACT OF THE DISCLOSURE Acrylate copolymers containing amino, hydroxyl and fluorine groups useful as additives for aqueous cationic coating systems for preventing surface flaws and for improv- ing 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, and fluorine from esters of (meth)acrylic acid. 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 system.
