Abstract
The present invention relates to coating compositions repairable by introduction of energy and comprising defined fatty acid esters, to coatings obtained therewith and repairable by introduction of energy, to methods of producing them, and to their use.
Claims20
A coating composition comprising as constituent components
- (A) at least one ester which has at least two hydroxyl groups, formally constructed of
- (A1) at least one fatty acid which contains at least 12 carbon atoms and
- (A2) at least one polyol having at least three hydroxyl groups,
- (B) at least one nonblocked or blocked di- or polyisocyanate, and
