Title (EN) CONDUCTIVE FILM, TOUCH PANEL SENSOR AND TOUCH PANEL
(FR) FILM CONDUCTEUR, CAPTEUR DE PANNEAU TACTILE ET PANNEAU TACTILE
(JA) 導電性フィルム、タッチパネルセンサー、及びタッチパネル
Abstract:
(EN) The present invention addresses the problem of providing a conductive film which comprises a metal thin wire that has a line width of 2.0 μm or less and exhibits excellent adhesion to a substrate for a long period of time. The present invention also addresses the problem of providing a touch panel sensor and a touch panel, each of which comprises this conductive film. A conductive film according to the present invention comprises a substrate and a conductive part that is arranged on at least one main surface of the substrate and is composed of a metal thin wire. The metal thin wire comprises a base layer and a conductive layer, which are sequentially arranged in this order from the substrate side, and a coating film that covers a lateral surface part of the base layer; and the metal thin wire has a line width of 2.0 μm or less. The base layer contains elemental nickel as a main component; the conductive layer contains copper as a main component; and the coating film has a thickness of less than 100 nm and contains a metal which is selected from among metals that are electrochemically more noble than nickel.
(FR) La présente invention a pour objet de fournir un film conducteur qui comprend un fil mince métallique qui a une largeur de ligne inférieure ou égale à 2,0 µm et qui présente une excellente adhérence à un substrat pendant une longue durée de temps. La présente invention a également pour objet de fournir un capteur de panneau tactile et un panneau tactile, comprenant chacun ledit film conducteur. Un film conducteur selon la présente invention comprend un substrat et une partie conductrice qui est disposée sur au moins une surface principale du substrat et est composée d'un fil mince métallique. Le fil mince métallique comprend une couche de base et une couche conductrice, qui sont agencées de manière séquentielle dans cet ordre à partir du côté substrat, et un film de revêtement qui recouvre une partie de surface latérale de la couche de base ; et le fil mince métallique a une largeur de ligne inférieur ou égale à 2,0 µm. La couche de base contient du nickel élémentaire en tant que composant principal ; la couche conductrice contient du cuivre en tant que composant principal ; et le film de revêtement a une épaisseur inférieure à 100 nm et contient un métal qui est sélectionné parmi les métaux qui sont électrochimiquement plus nobles que le nickel.
(JA) 本発明の課題は、線幅が2.0μm以下であり、且つ、長期間にわたって基板への密着性に優れた金属細線を含む導電性フィルムを提供することである。また、本発明の他の課題は、上記導電性フィルムを含む、タッチパネルセンサー、及びタッチパネルを提供することである。 本発明の導電性フィルムは、基板と、上記基板の少なくとも一方の主面上に配置された、金属細線から構成された導電部と、を含む導電性フィルムであって、 上記金属細線は、上記基板側からこの順に配置された下地層及び導電層と、上記下地層の側面部を被覆する皮膜と、を含み、且つ、線幅が2.0μm以下であり、 上記下地層は、ニッケル単体を主成分として含み、 上記導電層は、銅を主成分として含み、 上記皮膜は、ニッケルよりも電気化学的に貴な金属から選ばれる金属を含み、且つ、厚みが100nm未満である。
