    摘要: An aqueous binder dispersion that includes at least one copolymer (P) containing carboxylic acid and/or carboxylate groups. The copolymer (P) includes structural units of carboxyl-free (meth)acrylic esters with a cycloaliphatic structure, and at least 25 mol % of the carboxylic acid groups of the copolymer (P) in the dispersion being present in triethanolamine-neutralized form. The aqueous binder can be used in aqueous coating materials, which can be used to coat a substrate.
