Abstract
A nickel electroplating emulsion bath for obtaining a satin-finish which comprises an aqueous acidic continuous phase nickel salt solution, an alcohol soluble polyamide resin dispersed therein and a polishing agent and the method for using the bath. The polyamide resin is a member selected from the group consisting of a copolymer of dimer acid and an aliphatic amine, a copolymerized nylon and a modified nylon. The electroplating bath preferably also contains a cationic surface active agent selected from the group consisting of an aliphatic and/or aromatic quaternary ammonium salt and an aliphatic and/or aromatic fluorosulfonylamine quaternary ammonium salt. The use of the electroplating bath provides a means for obtaining a uniform satin-finish nickel plate surface on the material plated.
