GALVANIC NICKEL OR NICKEL ALLOY ELECTROPLATING BATH FOR DEPOSITING A SEMI-BRIGHT NICKEL OR NICKEL ALLOY, METHOD FOR ELECTROPLATING AND USE OF SUCH A BATH AND COMPOUNDS FOR THE SAME

摘要

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