Abstract
The deposit of palladium metal is characterized by a white colour having average white light reflectivity values, determined by spectrophotometric methods. ranging from about 78 to 95% of the average white light reflectivity of rhodium metal deposits at the same wavelengths and further characterized by being smooth and substantially free of dendritic deposits. The deposit may be obtained by electroplating, utilizing baths comprising a source of palladium metal, an ammonium conductivity salt, ammonium hydroxide to provide a pH of 5 to 10 and optionally an organic and a nickel containing inorganic brightener. <IMAGE>
