Abstract
Electroplating baths for obtaining white deposits of palladium metal comprise: (a) a source of palladium (e.g. palladium diaminodinitrite), (b) an ammonium conductivity, salt, (c) an organic brightener, and (d) ammonium hydroxide in an amount sufficient to adjust the pH to about 8 to 10, the source of palladium metal being present in an amount sufficient to deposit palladium but less than that which will cause darkening of the deposit. n
