ABSTRACT:
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.
