Abstract

The present invention relates to a process for the preparation of highly reactive, low-viscosity and water-dilutable polyisocyanate reaction products which contain activated groups which react, by polymerization, with ethylenically unsaturated compounds under the action of actinic radiation. The present invention furthermore relates to a process for the preparation of such products and their use.
