A process for electroplating palladium containing deposits from baths comprising a combination of a surfactant and a brightener combination. The surfactant is an alkyl, ammonium-type salt containing 4 to 35 carbon atoms. The brightener is 0-benzaldehydesulfonic acid, 1-naphthalene sulfonic acid, 2-n

A process for electroplating palladium containing deposits from baths comprising a combination of a surfactant and a brightener combination. The surfactant is an alkyl, ammonium-type salt containing 4 to 35 carbon atoms. The brightener is 0-benzaldehydesulfonic acid, 1-naphthalene sulfonic acid, 2-naphthalenesulfonic acid, benzenesulfinic acid, oxy-4,4-bis (benzene) sulfinic acid, p-toluene sulfinic acid, 3-trifluoromethyl benzene sulfinic acid, allyl phenyl sulfone, 0-benzoic sulfamide, benzylsulfonyl propionamide, phenylsulfonyl acetamide, 3-(phenylsulfonyl) propionamide, benzene sulfonamide, bis (phenylsulfonyl) methane, guanidine carbonate, sulfaguanidine or nicotinic acid. This combination provides deposits having superior adhesion and ductility.
