Abstract
Abstract In the process of chemical plating on a formed article composed of a polyarylene sulfide or a composition comprising a polyarylene sulfide as the predominant resin component, a method for selective chemical plating is provided, which comprises irradiating a portion not to be plated of the formed article with light of a wavelength of 0.1 nm to 800 nm and then subjecting the formed article to chemical plating.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
66 words
In the process of selectively chemical plating on a formed article composed of a polyarylene sulfide or a composition comprising a polyarylene sulfide the predominant resin component which comprises irradiating a portion not to be plated of the formed article with light of a wavelength from about 300 to about 404 nm from an ultraviolet light source and then subjecting the formed article to chemical plating.
Claim 2
Dependent Claim
66 words
In the process of selectively chemical plating on a formed article composed of a polyarylene sulfide or a composition comprising a polyarylene sulfide the predominant resin component which comprises irradiating a portion not to be plated of the formed article with light of a wavelength from about 300 to about 404 nm from an ultraviolet light source and then subjecting the formed article to chemical plating.
