Abstract

A process for the production of olefinically unsaturated isocyanates by reacting a1) isophorone diisocyanate or mixtures of isophorone diisocyanate with a2) other organic polyisocyanates with b1.1) olefinically unsaturated carboxylic acids or mixtures thereof with b1.2) other monobasic or polybasic carboxylic acids, b2.1) olefinically unsaturated alcohols and/or b2.2) other monohydric or polyhydric alcohols, the unsaturated resulting isocyanates and their use as binders for one-component coating compositions which may be cured at room temperature.
