    摘要： An aqueous coating composition containing A) one or more water-dilutable polyester polyols having an OH number of from 20 to 300 mg KOH/g and an acid number of from 20 to 80 mg KOH/g, obtained by reacting a) 49 to 40 mol % of a carboxylic acid component containing a1) one or more aliphatic, cycloaliphatic, araliphatic and/or aromatic carboxylic acids with a COOH functionality ≧2 and a2) optionally, aromatic, cycloaliphatic and/or aliphatic monocarboxylic acids with b) 51 to 60 mol % of an alcohol component containing b1) one or more aliphatic, cycloaliphatic and/or araliphatic polyols with Mn of from 62 to 272 g/mol and an average OH functionality ≧2 and b2) optionally, aliphatic, cycloaliphatic and/or araliphatic mono alcohols, B) one or more OH-reactive crosslinkers C) water, D) neutralizing agents and E) optionally solvents, auxiliaries and additives. The aqueous coating compositions can be used for coating metal substrates, such as cans.

    摘要： An aqueous binder composition having a reduced tendency to yellow containingA) 20 to 95 wt-% of a water-dilutable organic polyol component that is present in the form of an aqueous solution or dispersion, contains one or more polymer-modified polyester resins which contain carboxylate groups and hydroxyl groups and has been prepared by the polymerization of olefinically unsaturated monomers in the presence of an unsaturated polyester resin that is copolymerized with the monomers andB) 5 to 80 wt-% of at least one heat-activatable cross-linking resin,wherein the percentages are based on the solids contents of components A) and B) and add up to 100%; and their use in heat-curable coating compositions.
