Composition for metal electroplating comprising leveling agent

摘要

A composition comprising a source of metal ions and at least one leveling agent obtainable by
condensing at least one trialkanolamine of the general formula N(R 1 -OH) 3 (Ia) and/or at least one dialkanolamine of the general formula R 2 -N(R 1 -OH) 2 (Ib) to give a polyalkanolamine(II),
wherein
- the R 1 radicals are each independently selected from a divalent, linear or branched aliphatic hydrocarbon radical having from 2 to 6 carbon atoms, and
- the R 2 radicals are each selected from hydrogen and linear or branched aliphatic, cycloaliphatic and aromatic hydrocarbon radicals having from 1 to 30 carbon atoms,
or derivatives obtainable by alkoxylation, substitution or alkoxylation and substitution of said polyalkanolamine(II).
