Abstract
Acrylate copolymers containing hydroxyl groups as additives for aqueous anionic paint systems for the purpose of preventing surface defects are described. The acrylate copolymers contain selected amounts of hydroxyl groups originating from hydroxyethyl (meth)acrylates or hydroxypropyl (meth)acrylates, in addition to carboxyl groups neutralizable with bases. The additives are used in amounts of from 0.1 to 2.0% by weight, calculated on solids content and based on the total solids content of the binder in the paint.
