摘要： The present invention is concerned with a process for producing biuret polyisocyanates and the polyisocyanates so produced. These isocyanates are produced by the reaction of at least about a four fold molar excess of a diisocyanate having aliphatically bound isocyanate groups with amino alcohols having a particular structure at a temperature between about 90 and 200.degree. C. The amino alcohols contain at least three carbon atoms, have their hydroxyl and amino groups separated by at least two carbon atoms, and may contain urea, urethane, ether or amino bonds. The present invention is also concerned with a process for producing two component and one component moisture curing lacquers using the biuret polyisocyanates of the present invention and the lacquers so produced.
