摘要：The invention concerns the use of hydroxyl-containing acrylate copolymers asadditives for aqueous cationic coating systems for preventing surface flaws withoutimpairing the adhesion of subsequent layers, in particular of PVC-containing coatingmaterials. The acrylate copolymers contain not only acid-neutralisable amino groups butalso a selected amount of hydroxyl groups derived from monoesters of (meth)acrylicacid with diols. The additives are used in an amount of from 0.5 to 5.0% by weight,calculated on solids and based on the solids content of the binder in the coatingcomposition.
