    • An air-drying and oven-drying lacquer binder based on a copolymer having copolymerized units of5 to 40% by weight of styrene,10 to 50% by weight of at least one hydroxyalkyl(meth)acrylate with 2 to 4 carbon atoms in the alkyl group, and10 to 40% by weight of at least one (meth)acrylic acid ester with 1 to 10 carbon atoms in the alcohol component, esterified with10 to 50% by weight, based on the copolymer and drying fatty acid and dicarboxylic acid anhydride, of a drying fatty acid,from 10 to 70 mole % of the hydroxyl groups of the incorporated hydroxyalkyl(meth)acrylate units having been esterified with the drying fatty acid and thereafter from 0.5 to 20 mole % of the hydroxyl groups of the incorporated hydroxyalkyl(meth)acrylate units having been reacted with from 0.5 to 10% by weight, based on the lacquer binder, of at least one dicarboxylic acid cyclic anhydride to form the semiester of the corresponding dicarboxylic acid having an overall acid number of from 5 to 30, the overall acid number being composed of an acid number of from 1 to 10, as determined after esterification with the drying fatty acid and emanating from the free fatty acid, and of acid number of from 1 to 29, as determined on the solvent-free lacquer binder (end product) and emanating from formation of the semiester.
