Olefinically unsaturated isocyanates

摘要

The present invention relates to olefinically unsaturated, urethane group-containing isocyanates which are prepared by reacting at an NCO/OH equivalent ratio of 4 to 40 a) an isocyanate component substantially containing urethane group-free cycloaliphatic diisocyanates with b) an unsaturated alcohol component substantially containing monohydric olefinically unsaturated alcohols and subsequently removing distillable unreacted isocyanates by distillation. The present invention also relates to a process for the preparation of these isocyanates and to their use as a binder component in one-component, coating compositions which may be cured at room temperature.
