| abstract |
The present invention is prepared from aliphatic, cycloaliphatic, araliphatic and / or aromatic diisocyanates, wherein (a) the average isocyanate functionality is at least 2.0 and (b) the isocyanate group content (calculated as NCO, molecular weight = 42) is a resin solid. 5.0 to 25.0% by weight, and (c) the content (C 2 H 4 O, molecular weight 44) of the ethylene oxide units incorporated in the polyether chain comprising an average of 5 to 35 ethylene oxide units. From 2 to 50% by weight, based on solids, of at least 60 mole% of the polyether chains in a water dispersible polyisocyanate mixture connected through an allophanate group to two polyisocyanate molecules each prepared from two or more diisocyanate molecules It is about.n n n The present invention also relates to a process for producing the water dispersible polyisocyanate. |
