Die Erfindung betrifft wasserlösliche oder wasserdispergierbare hydrophile Polyisocyanate und Polyisocyanatgemische, ein Verfahren zu deren Herstellung, und deren Verwendung als Ausgangskomponente bei der Herstellung von Polyurethan-Kunststoffen, insbesondere als Vernetzer für wasserlösliche oder wasserdispergierbare Lackbindemittel, Klebstoffbindemittel, oder Dichtstoffbindemittel oder Bindemittelkomponenten mit gegenüber Isocyanatgruppen reaktionsfähigen Gruppen. The invention relates to water-soluble or water-dispersible, hydrophilic polyisocyanates and polyisocyanate mixtures, to a process for preparing them, and to their use as a starting component in the production of polyurethane polymers, more particularly as crosslinkers for water-soluble or water-dispersible film-forming binders, adhesives binders, or sealant binders or binder components with or without groups which are reactive towards isocyanate groups.
