Zusammenfassung:	A water-dispersible polyisocyanate mixt. (I) (a) has an average NCO functionality of 1.8-4.6, (b) contains 7.0-21.5 wt.% NCO gps., and (c) contains 5-25 wt.% ethylene oxide (EO) units in polyether-ester chains of formula Y-(Z-O)m-(CO-(CH2)5-O)n- (I), where Y is R -O- or R R N-; R -R are each a (non)satd. (cyclo)aliphatic, (alkyl)aromatic or araliphatic gp. with up to 18C atoms and 0-3 O, S and/or N hetero-atom(s), or NR R is a heterocycle with 3-5C and opt. an O or another N atom; Z is at least 70 mole% -CH2-CH2-, remainder -CH2-CHMe-; m = 5-70; n = 0.5-5; and m, n = at least 3.5. Also claimed is a method of preparing (I).
