Patent number: 11337316Abstract: A laminate that includes a metal layer that is not easily separated from a substrate, a method for producing the laminate, and a method for forming a fine conductive pattern that exhibits high conductivity, are disclosed. The peel strength of a metal layer included in a laminate that includes a polymer layer provided between a substrate and the metal layer is improved by implementing a structure in which the metal that forms the metal layer is chemically bonded to COO that extends from the polymer main chain that forms the polymer layer at the interface between the metal layer and the polymer layer. A fine conductive pattern that exhibits high conductivity can be formed by applying UV light to a pattern area of an insulating film formed on a substrate, and applying an ink prepared by dispersing metal nanoparticles in a solvent to the substrate to effect adhesion and aggregation of the ink in the pattern area, the surface of the metal nanoparticles being protected by an organic molecule layer.Type: GrantFiled: November 2, 2018Date of Patent: May 17, 2022Assignee: NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGYInventors: Tatsuo Hasegawa, Toshikazu Yamada, Ken Matsuoka, Ayano Katou
