Abstract
Solvent-containing clearcoat coating composition comprising (A) an OH-functional (meth)acrylate (co)polymer comprising (A1) 30%-99% by weight, based on the mass of the nonvolatile fraction of (A), of at least one OH-functional (meth)acrylate (co)polymer having an OH number of 60-200 mg KOH/g and glass transition temperature Tof 15° C. to 100° C., and (A2) 1%-70% by weight, based on the mass of the nonvolatile fraction of (A), of at least one OH-functional (meth)acrylate (co)polymer having an OH number of 60-200 mg KOH/g and a glass transition temperature Tof −100° C. to −20° C., (B) a crosslinker component comprising functional groups reactive toward OH, (C) 0.02%-1.2% by weight, based on the mass of the nonvolatile fraction of (A), of at least one polyamide and (D) 0.04%-2.9% by weight, based on the mass of the nonvolatile fraction of (A), of at least one urea adduct of a polyisocyanate and benzylamine.
