| abstract | 1454078 Catalytic solution for electroless plating INTERNATIONAL BUSINESS MACHINES CORP 26 Sept 1975 [6 Jan 1975] 39469/75 Heading C7F A catalyst solution for making surfaces receptive to electroless metallizing comprises a complex of a salt of Ru, Rh, Pd, Os, Ir, or Pt, with dimethyl sulphoxide, at least a stoichiometric amount based on the Gp VIII salt of a Gp IV metal salt capable of reducing the Gp VIII metal to elemental form, and an organic solvent. The Gp VIII salt may be PdCl 2 , H 2 PtCl 6 RuCl 3 , PtCl 2 or Pd(NO 3 ) 2 ; the Gp IV salt may be a Ti, Ge, or Sn<SP>++</SP> salt, e.g. SnCl 2 . The solvent may be a ketone, e.g. Me 2 CO, MeEtCO, an alcohol, e.g. MeOH, EtOH, an ether, e.g diethyl ether, or an ester, e.g. methyl or ethyl acetate; there may be 5-200 ml DMSO per gm of Gp VIII salt, and 0.001-10 g/l of Gp VIII salt in the solution. A substrate of stainless steel, Cr, Al, Mo, V, W, Cu, Ni, Ag or Au, or a silicate- or non- silicate-glass or a polymer is contacted for 5 min - 2 hours with the solution, and may be baked at 150-200‹C for 5 min-2 hours prior to electroless plating with As, Cr, Co, Co-Ni, Cu, Au, Fe, Ni or Pd; the coating may be thickened electrolytically; in an example a coating is formed of electroless Ni over electrolytic Cu over electroless Ni. |
