Abstract
The present invention relates to a process for producing scratch-resistant coatings which comprises applying a coating composition which in the cured state has a storage modulus E′ in the rubber-elastic range of at least 10,Pa and a loss factor tan &dgr; at 20° C. of not more than 0.10, the storage modulus E′0 and the loss factor having been measured by dynamic mechanical thermoanalysis on homogeneous free films having a film thickness of 40±10 &mgr;m. The present invention additionally relates to the use of the process for producing multicoat finishes and also to coating compositions suitable for this process.
