Abstract

Two-component polyurethane coating compositions containing wherein the binder contains polyisocyanates and certain polyester polyols having hydroxyl numbers of 80 to 250 prepared from a) polyol mixtures and b) aliphatic unsaturated dicarboxylic acids and, optionally, aliphatic saturated dicarboxylic acids, and their use for the production of coatings on plastic moldings such as those used in automobile construction.
