Claim 0:
1. An aqueous composition, comprising at least one metal ion and at least one compound of formula I, X1 is independently a linear or branched C1-C12 alkanediyl, which is substituted or unsubstituted, and optionally interrupted by O, S or NR40;
R11 is Z, X5—Z, or X4—N(Z)2;
Z is a branching group of formula III, R12 is H, R11, or R40;
R13, R14 are (a) independently H, R11, or R40, or (b) R13 and an adjacent group R14 together form a bivalent group X13, wherein, for (a) or (b), with the provision that n>2, two adjacent groups R14 optionally together form a bivalent group X13;
R31, R32 are independently a monovalent C2 to C6 polyoxyalkylene group, wherein a further branching group is optionally present in R31 and/or R32 to form a multiple branching group (Zp)p(R31R32)2p;
Zp is, R40 is (a) a linear or branched C1-C20 alkyl, which optionally is substituted by hydroxyl, alkoxy or alkoxycarbonyl, or (b) a linear or branched C1-C20 alkenyl, which is optionally substituted by hydroxyl, alkoxy or alkoxycarbonyl;
each X3 is independently a linear or branched C1 to C12 alkanediyl, which optionally is interrupted by O and S atoms or substituted by O—R31;
each X4 is independently a linear or branched C1 to C12 alkanediyl;
each X5 is independently a divalent group of at least one C2 to C6 polyoxyalkylene;
X13 is a linear or branched C1-C12 alkanediyl, which optionally is interrupted by O, S or NR40;
n is an integer of from 0 to 6; and
p is an integer of from 2 to 4;
wherein the aqueous composition is for metal electroplating; and
wherein the at least one metal ion comprises copper ions, cobalt ions, or tin ions.
