Organic isocyanate compositions are prepared by reacting organic polyisocyanates alone or in the presence of other organic compounds which contain reducible functional groups with catalytically activated hydrogen. New N-formyl-N,N'-disubstituted diisocyanato ureas may be prepared by this method. The products of this invention are particularly useful for producing light fast lacquers, coatings, adhesives, telomers and foam plastics.
有机异氰酸酯组合物是通过将有机聚异氰酸酯单独或与含还原性官能团的其他有机化合物在催化氢的存在下反应制备的。新的N-甲酰基-N,N'-二取代的二异氰酸酯脲可以通过这种方法制备。本发明的产品特别适用于生产耐光漆、涂料、粘合剂、末端聚合物和泡沫塑料。
