The present invention is directed to polyisocyanates that include at least one of i) or ii) i) nonionically hydrophilicizing groups based on polyalkylene oxide polyethers containing at least 30% by weight ethylene oxide units. ii) ionically or potentially ionically hydrophilicizing groups which on interaction with water enter into a pH-dependent dissociation equilibrium and are therefore neutral or positively or negatively charged depending on pH, and iii) at least one structural unit of the formula (1) (see formula 1) in which X is an electron-withdrawing group, R1, R2 independently of one another are a hydrogen atom, a saturated or unsaturated aliphatic or cycloaliphatic radical or an optionally substituted aromatic or araliphatic radical and each contain up to 12 carbon atoms and n is an integer from 0 to 5.
L'invention concerne de nouveaux polyisocyanates bloqués hydrophilisés, un procédé pour leur production et leur utilisation.
