Method of manufacturing surface metal film material, surface metal film material, method of manufacturing patterned metal material, patterned metal material, and polymer layer-forming composition
The present invention provides a method of manufacturing capable of readily obtaining a surface metal film material that has excellent adhesiveness of a metal film, reduced variability of adhesion due to humidity changes and excellent heat resistance and flexibility, and a method of manufacturing capable of readily obtaining a patterned metal material excellent in insulation reliability of a region where a patterned metal is not formed, and excellent in heat resistance and flexibility.;A method of manufacturing a surface metal film material includes: forming a polymer layer including a polymer that has a cyano group and that chemically bonds directly with a polyimide film, on the polyimide film; imparting a plating catalyst or a precursor thereof to the polymer layer; and performing a plating process on the plating catalyst or the precursor thereof, and a method of manufacturing a patterned metal material including etching a pattern in a plating film of a surface metal film material obtained according to the method of manufacturing a surface metal film material.
