Abstract: This invention relates to an aqueous coating medium which contains, as binder vehicles in the form of aqueous polymer dispersions,A) 50 to 90% by weight of one or more thermoplastic copolymers of at least one C2-C4 olefin and at least one vinyl ester of a C2-C11 monocarboxylic acid, wherein the olefin(s) and vinyl ester(s) are present in a ratio by weight of 10:90 to 40:60 and together make up at least 80% by weight of the copolymer,B) 10 to 50% by weight of one or more thermoplastic (meth)acrylic copolymers which are free from comonomers containing nitrile and amide groups, and at least 50% by weight of which consists of (meth)acrylic acid esters of C1-C18 alcohols, andC) 0 to 30% by weight of one or more copolymers which are different from A) and B),wherein the percentages by weight are given with respect to the resin solids in each case and add up to 100% by weight.

Abstract: A binder composition, a coating composition containing this binder, a process for its production and use to produce single or multi-layer lacquer coatings, particularly in the automotive sector, are described. The binder composition containsA) 25 to 75 wt. % of one of more resins containing carboxyl groups, which may contain .alpha.,.beta.-unsaturated groups, with a number average molecular weight (Mn) of 500 to 10000 g/mol and an acid value of 15 to 200 mg KOH/g,B) 25 to 75 wt. % of one or more polyethers, polyesters, polyether/polyesters and/or (meth)acrylic copolymers with at least one .alpha.,.beta.-unsaturated group and at least one epoxy group per molecule, wherein the .alpha.,.beta.-unsaturated groups and epoxy groups are present in a numerical ratio of 20:80 to 80:20, with a number average molecular weight (Mn) of up to 10000 g/mol,C) 0 to 60 wt. % of one or more polyols with at least two hydroxyl functional groups per molecule,D.sub.1) 0 to 20 wt. % of one or more melamine resins,D.sub.2) 0 to 40 wt.
