PROBLEM TO BE SOLVED: To provide a modified nickel or nickel alloy electroplating bath for depositing a semi-bright nickel or nickel alloy coating on a substrate, which does not show disadvantages known in the prior art nickel electroplating bath.SOLUTION: The present invention is related to a nickel or nickel alloy DC electroplating bath for depositing a semi-bright nickel or nickel alloy coating, where the electroplating bath comprises at least one compound having the general formula (I), where Ris a C-Chydrocarbon moiety substituted with a SOgroup, a C-Chydrocarbon moiety substituted with a carboxylic group or a C-Chydrocarbon moiety substituted with at least one aromatic and/or a heteroaromatic group; Ris a NRRmoiety, ORmoiety, or cyclic NRmoiety, where R, Rand Rare each hydrogen, a C-Chydrocarbon moiety, or a C-Chydrocarbon moiety substituted with at least one aromatic and/or a heteroaromatic group, are identical or different, and Ris a C-Chydrocarbon moiety or a C-Chydrocarbon moiety where at least one carbon atom is substituted with a heteroatom; and n=1-3.SELECTED DRAWING: None |
