Coating composition obtainable by polyaddition of a non-aqueous starting mixture, comprising:
(1) 10 wt. % to 70 wt. % of a non-aqueous solution of a polymer based on acrylate with an OH number between 100 and 250;
(2) 10 wt. % to 70 wt. % of a non-aqueous solution of a fluorine-modified polymer having a glass transition temperature between 20 and 40° C. and
(3) 20 wt. % to 60 wt. % of at least one blocked aliphatic or cycloaliphatic polyisocyanate; the weight ratio of component (1) to component (2) amounting to at most 1 and the sum of components (1), (2) and (3) amounting to 100%, based on the binder content of the starting mixture to be crosslinked, and use of this coating composition as clear coat, in particular in the automotive industry.
