ABSTRACT:
The present invention relates to a hydroxy-functional polyester resin, which is obtainable by reaction of a composition, which contains (i) a low-molecular polyvalent alcohol having at least two hydroxyl groups per molecule, (ii) a polyether polyol, (iii) a monofunctional saturated aliphatic, cycloaliphatic or aromatic carboxylic acid, and (iv) a polycarboxylic acid having at least two carboxyl groups. The invention further relates to a resin emulsion and a mother paint comprising an aqueous emulsion of the polyester resin, a two-component water-based paint system, comprising the resin emulsion or the mother paint and an isocyanate component as well as a method for the preparation of the water-based paint system.
