Aliphatic and/or cycloaliphatic polyisocyanates containing allophanate groups are produced by reacting (a) a di- and/or polyisocyanate with aliphatic and/or cycloaliphatic isocyanate groups with (b) a hydroxy compound at a temperature of at least 150°C for no more than 90 minutes and then rapidly cooling the reaction mixture to a temperature of less than 100°C. It is preferred that the reaction be carried out in, the absence of oxygen. The products thus obtained are virtually colorless, have a relatively low viscosity and excellent storage stability.
