Patent number: 8974872Abstract: A process for producing a multilayer film which, even when bent, is less apt to decrease in barrier property or electrical conductivity. The process comprises forming a barrier film and a transparent conductive film on a resin film to produce a multilayer film. The barrier film is formed by a plasma enhanced CVD method which uses electric discharge between rolls. The transparent conductive film is preferably formed by physical vapor deposition. The resin film preferably is a polyester resin film or a polyolefin resin film.Type: GrantFiled: October 26, 2010Date of Patent: March 10, 2015Assignee: Sumitomo Chemical Company, LimitedInventors: Akira Hasegawa, Toshiya Kuroda, Takashi Sanada
