Abstract
Abstract This invention relates to a process for conditioning the surfaces of polyester and polyamide materials for electroless plating of a metal coating thereon by exposing such materials to a composition comprising a solvent system containing water, and one or more substantially water-soluble organic solvents and an effective amount of solvated hydroxide ions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
70 words
In an improved process for metal plating a polyamide material by conditioning said material to improve metal adhesion and depositing a metal coating upon said conditioned surface from an electroless plating bath, wherein said improvement comprises a conditioning step in which said material is exposed to a composition comprising a solvent system containing water and one or more substantially water-soluble organic solvents and an effective amount of solvated hydroxyl ions.
Claim 2
Dependent Claim
70 words
In an improved process for metal plating a polyamide material by conditioning said material to improve metal adhesion and depositing a metal coating upon said conditioned surface from an electroless plating bath, wherein said improvement comprises a conditioning step in which said material is exposed to a composition comprising a solvent system containing water and one or more substantially water-soluble organic solvents and an effective amount of solvated hydroxyl ions.
Claim 3
Dependent Claim
73 words
An improved process for plating one or more metals onto the surfaces of a polyamide material which comprises: (a) exposing said material to a solution comprising water, one or more substantially water-soluble organic solvents and an effective amount of hydroxyl ions; (b) coating said contacted material with a catalyst for electroless plating of one or more metals thereon; and (c) depositing one or more metal coatings on said catalyzed material by electroless plating.
Claim 4
Dependent Claim
73 words
An improved process for plating one or more metals onto the surfaces of a polyamide material which comprises: (a) exposing said material to a solution comprising water, one or more substantially water-soluble organic solvents and an effective amount of hydroxyl ions; (b) coating said contacted material with a catalyst for electroless plating of one or more metals thereon; and (c) depositing one or more metal coatings on said catalyzed material by electroless plating.
Claim 5
Dependent Claim
24 words
An improved process according to claim 2 wherein said one or more metals are selected from the group consisting of copper, nickel and cobalt.
Claim 6
Dependent Claim
27 words
An improved process according to claim 3 which further comprises depositing one or more additional metal coatings onto said metal coated material of step (c) by electroplating.
Claim 7
Dependent Claim
25 words
An improved process according to claim 4 wherein said one or more additional metals are selected from the group consisting of copper, nickel and chromium.
