Patent ID: 7279195

Claim:
A method of forming a metal particle pattern, comprising: forming a polymerization initiation layer on a support, the polymerization initiation layer comprising copolymer that comprises a copolymer component A having a functional group having the ability to initiate polymerization in an amount of 1-40% by mole and a copolymer component B having a cross-linking group in an amount of 20-70% by mole, wherein the copolymer is fixed by a cross-linking reaction to form the polymerization initiation layer; pattern-wise forming a graft polymer region on a surface of the polymerization initiation layer, wherein the graft polymer region has the ability to contain a metal ion or a metal salt; adding a metal ion or a metal salt to the graft polymer region; and thereafter reducing the metal ion or a metal ion in the metal salt to form a metal particle dispersion region.
