Publication number: 20170087586Abstract: Provided is a method for readily forming a coating film on a surface of a substrate, that has an excellent applicability and is uniform or homogenous and has a good appearance. The present invention is a method for forming a coating film on a surface of a substrate. The method comprises the steps of: applying an aqueous coating composition to a surface of the substrate to form a liquid film, and drying the liquid film to form a dry film. The liquid film has a fine concave-convex shape including a plurality of convex parts and a plurality of concave parts. In the step of forming the dry film, the liquid film is dried to form the dry film in which the fine concave-convex shape of the liquid film is conserved.Type: ApplicationFiled: September 29, 2016Publication date: March 30, 2017Inventors: Tetsuya SHICHI, Mami IKEDO, Kyoko KATAOKA

Patent number: 8426107Abstract: Disclosed is a positive-type photosensitive composition which can form a metal compound film pattern at high resolution and with less affection by organic residues. The positive-type photosensitive composition comprises: a metal complex component (A) which can form a metal compound film when applied and subsequently fired; and a photosensitizing agent (B). In the composition, a ligand in the component (A) is preferably a multidentate ligand having an aromatic compound as its skeleton. According to this construction, even a composition containing substantially no photosensitive resin can impart photosensitivity and a metal compound film pattern can be formed readily.Type: GrantFiled: May 13, 2009Date of Patent: April 23, 2013Assignees: Tokyo Ohka Kogyo Co., Ltd., Central Japan Railway CompanyInventors: Motoki Takahashi, Toshiyuki Ogata, Christopher Cordonier, Akimasa Nakamura, Tetsuya Shichi, Teruhiro Uematsu
