Patent ID: 8273462

Claim:
A process for producing a metal film, comprising the steps of: (a) forming an organic film by (i) applying a primer composition to a substrate or a film and thereafter (ii) polymerizing the primer composition, the primer composition containing (i) an addition polymerizable compound including three or more reactive groups, (ii) an addition polymerizable compound including an acid group, and (iii) an addition polymerizable compound including a hydrophilic functional group; (b) forming a metal (M1) salt from the acid group by processing the organic film with an aqueous solution containing a metal (M1) ion; (c) substituting the metal (M1) salt of the acid group with a metal (M2) salt by processing the organic film, which has been processed with the aqueous solution containing the metal (M1) ion, with a metal (M2) ion aqueous solution containing a metal (M2) ion which has a less ionization tendency than the metal (M1) ion; (d) reducing the metal (M2) ion so that a metal film is formed on a surface of the organic; and (e) oxidizing the metal film, wherein the metal (M2) ion aqueous solution includes polyol, which is selected from a group consisting of glycerin, polyethyleneglycol, and sorbitol.
