An aqueous binder combination essentially comprising A) an aqueous solution or dispersion of a water-dilutable organic polyol component, essentially comprising at least one carboxylate- or hydroxyl-containing polyester resin which is grafted with vinyl monomers, and B) a polyisocyanate component emulsified in component A), a process for the preparation of coating compositions based on a binder combination of this type, by emulsification of a polyisocyanate component B) in an aqueous solution or dispersion A) of a water-dilutable polyol component of this type, where the mixing ratios between the two components correspond to an NCO/OH equivalent ratio of from 0.5:1 to 5:1, and the use of the binder combination as binders for paints (lacquers, varnishes, enamels), coating compositions or sealants. |
