ABSTRACT:
Air-drying or heat-curable coating compositions are based on allyl ether group-containing isocyanate adducts which are obtained by reacting isophorone diisocyanate with a polyhydroxy compound to give an intermediate containing free isocyanate groups, and then condensing the intermediate with an hydroxyl group-containing allyl ether of an aliphatic diol or polyol.
