Abstract
The present invention relates to a process for the preparation of particularly reactive and low-viscosity reaction products of polyisocyanates which contain activated ethylenically unsaturated groups which react by polymerization under the action of actinic radiation, and the use of these reaction products in coating compositions, and particularly scratch-resistant coatings obtainable therefrom.
