摘要：framework of aqueous disperisonen from exposure to high-energy radiationcured polyurethanes from (a) a polyisocyanat, (b) a polyol with a molecular weight ofbetween 400 and 6 000 g \\/ mol, (c) where appropriate, a polyol with a molecular weightbetween 62 and 399 g \\/ mol(d) where appropriate, a polyamin with at least two withisocyanate reactive amine groups, and (e) where appropriate, a aminoalkohol with at leastone compared with isocyanate reactive amino\­gruppe, (f) a connection with ionicgroups or ionic groups \über\­f\ührbaren groups mi t of at least onereactive hydroxyl or amine group to isocyanate.(g) where appropriate, a

monofunktionellen polyetherol and (h) a compound with at least one ethylenischunsaturated group and at least one hydroxylgruppe.characteristic is that the link with aethylenisch unsaturated group (h), in quantities of from 0.02 to 0.08

gramm\äquivalent oh, relative to the polyisocyanat (a) is used and that the

polyurethane dissolved in dimethylformamid a k value greater than 40 in fikentscher or indimethylformamid is not soluble.
