Abstract:
1. A method of forming a layer or layers, the method comprising the steps of: a) transporting a cellulose ester film to a gap formed between a first electrode and a second electrode opposing each other to make a plasma discharge; the cellulose ester film having a first surface and a second surface opposite to the first surface; the cellulose ester film having a hardened resin layer, which is prepared by polymerizing and hardening a monomer or an oligomer each having an ethylenically unsaturated double bond by an ultraviolet ray, on the first surface; and b) subjecting the hardened resin layer of the cellulose ester film to plasma discharge treatment to form a layer on the hardened resin layer at atmospheric pressure or at approximately atmospheric pressure while supplying a reactive gas to the gap.
