Abstract

Bains de revêtement électrolytique du palladium brillant. Ces bains comprennent du palladium essentiellement pur, exempt d'éléments d'alliage, étant sous forme pouvant être déposée par voie électrolytique, ainsi qu'un produit de brillance (brillanteur) de classe I choisi dans le groupe se composant de méthylène-bis(naphtalènesulfonate de sodium), de benzènesulfonate de sodium, de benzènesulfonimide et d'acide phénylsulfonique, et un produit de brillance organique de classe II choisi dans le groupe se composant de benzaldéhyde-o-sulfonate de sodium, de 2-butyne-1,4-diol, de 2-butène-1,4-diol et de sulfonate d'allyle, pour améliorer la brillance du dépôt. La présente invention est particulièrement utile pour le revêtement de palladium brillant pur.Bright palladium electrolytic coating baths. These baths comprise essentially pure palladium, free of alloying elements, being in electrolytically settable form, as well as a class I gloss (brightener) selected from the group consisting of methylene-bis ( sodium naphthalenesulfonate), sodium benzenesulfonate, benzenesulfonimide and phenylsulfonic acid, and a Class II organic gloss product selected from the group consisting of sodium benzaldehyde-o-sulfonate, 2-butyne-1,4 -diol, 2-butene-1,4-diol and allyl sulfonate, to improve the gloss of the deposit. The present invention is particularly useful for the coating of pure bright palladium.
