Abstract

Procedure for obtaining aqueous baths for the electrolytic deposit of gold or a gold alloy on a conductive article, characterized in that a trivalent gold compound is mainly reacted with an amine and then the product obtained is reacted with at least two equivalent moles of an alkaline sulphite, the product being further dissolved in water, to produce an aqueous bath with a pH equal to or greater than 4.5.
