A catalyst-free, one-component coating composition containing A) one or more compounds which act as crosslinking agents and contain on average at least two CH-acidic hydrogen atoms, B) one or more Michael addition-suitable (meth)acrylate copolymers, polyester and/or polyurethane resins containing alpha , beta -unsaturated groups bonded via carbonyl, carboxyl and/or carboxamide groups, and having a C=C equivalent weight of 85-1800 and a weight average molecular weight of 170-50000. The equivalent ratio of A:B is from 2:1 to 1:2. The coating composition contains solvents and additives which are customary in paints, and optionally water, pigments and/or fillers. It gives particularly acid-resistant coatings and is particularly suitable for the production of top coats and clear coats in the automotive sector. |
