Abstract

Decomposition products of GAFAC* (anionic phosphate ester of an alkylphenylether) are added to the copper bath made up of the usual constituents. The decomposition products are produced by oxidizing an aqueous solution of GAFAC, for example, by electrolysis or by bubbling through air. The solution thus treated is added to the copper bath. The added constituents increase the bath stability. * Trademark of General Aniline and Film Corp.
