Abstract
Abstract An article comprising a substrate body having a surface coated with a film of a resin having incorporated therein a hydrolyzed metal complex which has adsorbed thereon a metal or metal ion which is a catalyst for the deposition of a metal from an autocatalytic type metal plating bath. The article may also include a film of plated metal.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
82 words
An article of manufacture comprising a body having a surface comprising a resin, said resin having incorporated therein the hydrolysis product of a hydrolyzable metal selected from the group consisting of titanium, aluminum, and zirconium, said hydrolysis product having adsorbed thereon either a metal or metal ion, said adsorbed metal or metal ion being a catalyst for the autocatalytic deposition of a metal from a solution containing salt of nickel or copper, a reducing agent, a chelating agent and a pH-adjusting agent.
Claim 2
Dependent Claim
82 words
An article of manufacture comprising a body having a surface comprising a resin, said resin having incorporated therein the hydrolysis product of a hydrolyzable metal selected from the group consisting of titanium, aluminum, and zirconium, said hydrolysis product having adsorbed thereon either a metal or metal ion, said adsorbed metal or metal ion being a catalyst for the autocatalytic deposition of a metal from a solution containing salt of nickel or copper, a reducing agent, a chelating agent and a pH-adjusting agent.
Claim 3
Dependent Claim
20 words
An article according to claim 1 in which said substrate body surface comprises a resin which is hydrophobic in nature.
Claim 4
Dependent Claim
14 words
An article according to claim 2 in which said hydrophobic resin is a polytetrafluoroethylene.
Claim 5
Dependent Claim
13 words
An article according to claim 1 in which said hydrolyzable metal is titanium.
Claim 6
Dependent Claim
13 words
An article according to claim 1 in which said hydrolyzable metal is aluminum.
Claim 7
Dependent Claim
16 words
An article according to claim 1 in which said adsorbed metal or metal ion is silver.
Claim 8
Dependent Claim
16 words
An article according to claim 1 in which said adsorbed metal or metal ion is palladium.
Claim 9
Dependent Claim
89 words
An article of manufacture comprising a substrate body having a surface comprising a resin, said resin having incorporated therein the hydrolysis product of a hydrolyzable metal, selected from the group consisting of titanium, aluminum and zirconium, said hydrolysis product having adsorbed thereon a metal which is a catalyst for the autocatalytic deposition of nickel or copper from a solution containing a salt of nickel or copper, a reducing agent, a chelating agent and a pH adjusting agent, and a film of the deposited metal adhered to the catalyzed surface.
Claim 10
Dependent Claim
89 words
An article of manufacture comprising a substrate body having a surface comprising a resin, said resin having incorporated therein the hydrolysis product of a hydrolyzable metal, selected from the group consisting of titanium, aluminum and zirconium, said hydrolysis product having adsorbed thereon a metal which is a catalyst for the autocatalytic deposition of nickel or copper from a solution containing a salt of nickel or copper, a reducing agent, a chelating agent and a pH adjusting agent, and a film of the deposited metal adhered to the catalyzed surface.
Claim 11
Dependent Claim
13 words
An article according to claim 8 in which the deposited metal is copper.
Claim 12
Dependent Claim
13 words
An article according to claim 8 in which the deposited metal is nickel.
Claim 13
Dependent Claim
16 words
An article according to claim 8 in which said substrate body surface comprises a hydrophobic resin.
Claim 14
Independent Claim
147 words
A method of electrolessly plating a non-metallic body with nickel or copper comprising: applying to said body a solution containing a resin binder, a metal compound that is hydrolyzable to form an oxide-hydroxide complex, and a volatile solvent for said resin binder and said metal compound capable of wetting the surface of said body, evaporating said solvent to form a film on said body, hydrolyzing said hydrolyzable compound, rinsing the film containing the hydrolyzed compound, applying to said film a solution of a metal compound wherein the metal is one which is catalytic to electroless deposition of nickel or copper, in order to adsorb metal ions from said compound on said film, rinsing the catalytic surface, and treating the catalytic surface with an electroless plating bath comprising a salt of nickel or copper, a reducing agent for said salt, a chelating agent and a pH adjusting agent.
Claim 15
Independent Claim
147 words
A method of electrolessly plating a non-metallic body with nickel or copper comprising: applying to said body a solution containing a resin binder, a metal compound that is hydrolyzable to form an oxide-hydroxide complex, and a volatile solvent for said resin binder and said metal compound capable of wetting the surface of said body, evaporating said solvent to form a film on said body, hydrolyzing said hydrolyzable compound, rinsing the film containing the hydrolyzed compound, applying to said film a solution of a metal compound wherein the metal is one which is catalytic to electroless deposition of nickel or copper, in order to adsorb metal ions from said compound on said film, rinsing the catalytic surface, and treating the catalytic surface with an electroless plating bath comprising a salt of nickel or copper, a reducing agent for said salt, a chelating agent and a pH adjusting agent.
Claim 16
Dependent Claim
17 words
A method according to claim 12 in which said body is composed of a hydrophobic synthetic resin.
Claim 17
Dependent Claim
16 words
A method according to claim 12 in which said hydrolyzable metal compound is a titanium compound.
Claim 18
Dependent Claim
18 words
A method according to claim 14 in which said metal ion which is adsorbed is silver or palladium.
Claim 19
Dependent Claim
44 words
A method according to claim 12 in which the resin film containing the hydrolyzed compound is treated with a solution of a reducing agent after the film has been treated with the catalytic metal and before treating the catalytic surface with the plating bath.
