Abstract:
Water-dispersible polyisocyanates which are obtained by reaction of the following starting components:a) modified polyisocyanates which consist essentially of modified polyisocyanates of the formula (I) ##STR12## in which: R.sup.1 denotes an aliphatic hydrocarbon radical having 2 to 18 carbon atoms; a cycloaliphatic hydrocarbon radical having 4 to 15 carbon atoms; an aromatic hydrocarbon radical having 6 to 15 carbon atoms or an araliphatic hydrocarbon radical having 8 to 15 carbon atoms,R.sup.2 denotes an aliphatic hydrocarbon radical which has 10 to 35 carbon atoms and optionally contains double bonds,R.sup.3 denotes a hydrocarbon radical which is at least divalent and can also be heterocyclic, or which, together with the ester oxygen or amide nitrogen of X, forms a heterocyclic radical,X denotes ##STR13## or a combination thereof, where R.dbd.H or C.sub.1 -C.sub.4 -alkyl, or a constituent of a cyclic structure,n denotes a number .gtoreq.2 and y denotes a number .gtoreq.1,b) non-modified polyisocyanates,c) polyethylene oxide polyether alcohols optionally containing ester groups,d) optionally cycloaliphatic and/or aliphatic amines which optionally contain ether, ester or amide groups, have at least one functional group which is reactive towards isocyanates and contain at least one tertiary amino group and/or ammonium group.
