Beschreibung
Zusammenfassung:	Polyurethane system comprises (a) a water-soluble urea group containing hydroxyl group polyurethane, where the amount of the hydroxyl group is 2-10 wt.% and the concentration of the urea group, which is derived from amino alcohol with a primary or secondary amino group and at least a hydroxyl group, is 3-20 wt.%; (b) crosslinker, which is free of isocyanate group and are optionally hydrophilized; and (c) optionally further water-soluble and/or dispersible and/or organically soluble, optionally hydroxyl functional oligomer and/or polymer. An independent claim is included for polyurethane obtained using the polyurethane system.
