(C) is an emulsion or water-soluble polymer comprising a sulfonium group obtained by copolymerization of the monomer (A) and a radical-polymerizable unsaturated monomer excluding the monomer (A). (D) is a composite emulsion comprising a sulfonium group wherein inorganic particle core are coated by a layer comprising a copolymer of the aforesaid monomer (A) and a radical-polymerizable unsaturated monomer excluding the monomer (A). The film-forming step (c-2) is a step for forming a film by electrodeposition wherein the metal material is dipped in an aqueous solution comprising at least one of the above compositions (A), (B), (C), (D), and a current is passed between a cathode and an anode with the metal material as cathode.
