摘要

Galvanic electroplating bath nickel or nickel alloy to deposit a coating of semi-bright nickel or nickel alloy characterized in that the electroplating bath comprises at least one compound having the general formula (I) ** ** Formula wherein R1 = a hydrocarbon residue C1 - C18 substituted with an SO3 - group, a hydrocarbon residue C1 - C18 substituted with a carboxylic group, or a hydrocarbon residue C1 - C18 substituted by at least one aromatic group and / or a heteroaromatic group ; R2 = A NR3R4 moiety, a OR5, or a cyclic moiety NR6, wherein R3, R4, R5 = hydrogen or a hydrocarbon radical C1 - C18 or a hydrocarbon residue C1 - C18 substituted with at least one aromatic group and / or a heteroaromatic group, wherein R3, R4 and R5 are the same or different; R6 = a hydrocarbon residue C3 - C8 hydrocarbon radical or C3 - C8 wherein at least one carbon atom is substituted by a heteroatom; n = 1 to 3.
