Abstract
An all-purpose gold cyanide electroplating bath utilizes a cobalt, nickel, or indium hardener as a chelate with the acid form of a methyl vinyl ether/maleic anhydride interpolymer. The bath is capable of producing high levels of hardness in deposits that are substantially pure gold; it is efficient, very stable, resistent to contamination, and it is well-suited for utility at a wide range of current densities.
