摘要： Coating composition suitable for multi-layer lacquerings, with a binder composition which comprises: A) 25 to 75 wt. % of carboxyl-functional (meth)acrylic copolymers and/or carboxyl-functional polyesters, the carboxyl functionality of which corresponds to an acid number of 15 to 300 mg KOH/g, B) 25 to 75 wt. % of epoxide-functionalized crosslinker resins, at least one of which is a (meth)acrylic copolymer which has been prepared co-using tert-butyl (meth)acrylate, C) 0 to 50 wt. % of polyols which have at least two hydroxyl functions in the molecule, D) 0 to 40 wt. % of components which crosslink with hydroxyl groups to form ethers, and/or of a crosslinking agent based on triazine, E) 0 to 40 wt. % of polyisocyanates, F) 0 to 50 wt. % of at least one organic polyanhydride with at least two cyclic carboxylic acid anhydride groups per molecule, G) 0 to 20 wt. % of reactive thinners with an epoxide function, H) 0 to 10 wt. % of one or more catalysts for the reaction of carboxyl and epoxide groups.
