Abstract
An improved bath for the electrolytic deposition of gold or gold alloys on electrically conductive objects contains an alkali metal gold sulfite, a gold alloy metal, an electrically conductive salt, a chelating agent, a water soluble salt of cadmium, a water soluble salt of copper, a water soluble salt of nickel, and a specified organic phosphorus compound. The bath is useful for depositing white gold on conductive objects.
