Beschreibung
Zusammenfassung:	The invention relates to the use of hydroxyl- and fluorine- containing acrylate copolymers as additives for aqueous anionic coating systems for preventing surface defects. The acrylate copolymers contain, in addition to bases of neutralisable carboxyl groups, in a selected amount, esters of (meth)acrylic acid containing fluorine and hydroxyl groups originating from hydroxyethyl or hydroxypropyl (meth)acrylates. The additives are added in an amount of from 0.1 to 2.0 % by weight, calculated as a solid and based on the solid content of the binder in the coating composition.
