Abstract
The invention relates to coating compositions comprising: PA1 (A) from 5 to 60% by weight of at least one polyester-modified polyacrylate resin consisting of: PA1 (a1) from 20 to 60% by weight of at least one polyester and PA1 (a2) from 40 to 80% by weight of at least one hydroxyl-containing polyacrylate resin which has been prepared at least in part in the presence of component (a1), PA1 (B) from 1 to 35% by weight of at least one hydroxyl-containing, siloxane-modified polyacrylate resin, and PA1 (C) from 5 to 50% by weight of an isocyanate crosslinking agent, PA1 and to a process for the production of a protective and/or decorative coating with such coating compositions, and to their use as topcoats and refinish coating materials.
