摘要： The present invention relates to coating compounds of which the binder consists essentially of a combination of a) a polyol component dissolved and/or dispersed in water or a water/solvent mixture, and b) a polyisocyanate component emulsified in the solution and/or dispersion of the polyol component with a viscosity at 23° C. of 50 to 10,000 mPa.s, in quantities corresponding to an equivalent ratio of isocyanate groups of component a) to alcoholic hydroxyl groups of component b) of 0.5:1 to 5:1, characterized in that component consists essentially of a1) a water-dilutable, hydroxyfunctional polycondensate resin free from urethane and sulfonate groups and having a molecular weight Mn above 500 or a2) a mixture of such a polycondensation resin with up to 100% by weight, based on the weight of the polycondensation resin, of at least one water-dilutable, hydroxyfunctional polymerization resin having a molecular weight Mn above 500. The present invention also relates to a process for the preparation of these coating compounds and to their use for the production of coatings.
