Abstract

Coating materials, processes for preparing them, and their use. The coating materials include hydroxyl-containing (meth)acrylate (co)polymer, carbamate- and hydroxyl-functional compound, an amino resin, and a triazine compound. At least 10 equivalent % of the hydroxyl groups present in (A) and/or (B) are primary hydroxyl groups. The coating materials after curing have a storage modulus E′ in the rubber-elastic range of at least 1.5*107 Pa, the storage modulus E′ having been measured by dynamic mechanical thermoanalysis (DMTA) on homogeneous free films with a thickness of 40±10 μm.
