The present invention relates to novel aspartates, their method of production and the use of these aspartates as reactive components for polyisocyanates in two-component polyurethane coating compositions and for preparing polyurethane prepolymers. The aspartaes are prepared by first reacting a di- or polyamine with an unsaturated ester and then reacting the resultant product with a ketone.
