Abstract

Acrylate copolymers containing hydroxyl and fluorine 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 and fluorine groups originating from 2-perfluoroalkethyl (meth)acrylate, 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.
