Abstract
An electroless plating bath comprises an aqueous solution containing from 1-20 g./l. of divalent palladium, from 0.04-0.50 g./l, of unsymmetrical dimethyl hydrazine and at least one amino compound from the group consisting of ammonia and aliphatic organic compounds having a primary amine group, e.g. aminoethyl ethanolamine, and amylamine in a total molar concentration equal to from 100-350 g./l. of ammonia. E.D.T.A. in a concentration not exceeding 80 g./l., ammonium chloride and sulphate may also be added. Catalytic metals, e.g. Al, Cr, Co, Cu, Au, Fe, Mo, Ni, Pd, Pt, Ru, Ag, Sn, and W, and glass, plastics or ceramics coated with a preliminary coating of e.g. Ni, Ag or Pd may be coated.
