ABSTRACT:
The present invention relates to novel aqueous or water-dilutable blocked polyisocyanates and to their use for the production of one-component polyurethane coating compositions, which are stovable at relatively low temperatures of 130.degree. to 150.degree. C. and provide clear coatings having substantially reduced thermal yellowing.
