Patent ID: 8202576

Claim:
A method of forming a metal film, the method comprising: (a) forming a primer layer on a substrate by applying a first polymer including a unit having a cyano group in a side chain; (b) forming a polymer layer on the surface of the primer layer by applying a second polymer, the second polymer having a functional group that interacts with an electroless plating catalyst or a precursor thereof and a polymerizable group; (c) applying the electroless plating catalyst or the precursor thereof to the polymer layer; and (d) forming a metal film on the polymer layer by performing electroless plating, wherein the first polymer comprises a polymer including a unit represented by the following formula (1): wherein in formula (1), R 1 represents a hydrogen atom or an alkyl group that may be substituted or unsubstituted; X represents a single bond, a divalent organic group that may be substituted or unsubstituted, an ester group, an amide group, or an ether group; and L 1 represents a divalent organic group that may be substituted or unsubstituted.
