摘要： An aqueous coating composition, comprising A) at least one water-dilutable hydroxy-functional binder and B) at least one polyisocyanate crosslinking agent with free isocyanate groups, wherein component A) comprises A1) 40-95 wt.% of at least one water-dilutable hydroxy-functional (meth)acrylic copolymer with a hydroxyl value of 60-250 mg of KOH/g and an acid value of 5-50 mg of KOH/g, which is obtained by free-radical copolymerization performed in a non-aqueous phase, wherein the ratio of primary hydroxyl groups to secondary hydroxyl groups in the (meth)acrylate copolymer A1) is 1: 0.1 to 1 :1.2 and at least 80% of the secondary hydroxyl groups result from reaction products of a monoepoxy ester and an unsaturated acid-functional monomer, and A2) 5-60 wt.% of at least one water-dilutable polyester oligomer, wherein the total of the weight percentages of component A1) and A2) add up to 100 wt.% and wherein the free-radical polymerization for the production of component A1) is performed at least in part in the presence of component A2) and/or wherein component A2) is added during polymerization or after completion of polymerization.

摘要： The invention is directed to aqueous coating composition comprising A) at least one water-dilutable (meth)acrylate copolymer and B) at least one polyisocyanate cross-linking agent with free isocyanate groups, wherein the (meth)acrylate copolymer comprise a) 10-80% by weight of at least one reaction product of a monoepoxyester and an unsaturated acid functional monomer b) 0-40% by weight of at least one hydroxy functional unsaturated monomer which is different from component a), c) 1-8% by weight of at least one unsaturated acid functional monomer and d) 0-70% by weight of at least one other polymerisable unsaturated monomer, wherein the% by weight of components A) and B) and of components a) to d) is adding up to 100% by weight and wherein the (meth)acrylate copolymer is prepared by a skew feed polymerization process with at least two feed streams and wherein one feed stream comprises the main quantity, namely 60-100% by weight of component a), based on the total amount of component a) and the lower amount, namely 0-30% by weight of the unsaturated acid functional monomer c) based on the total amount of monomer c).
