Patent number: 9427779Abstract: A method of forming a multilayer coating film with smoothness, distinct image, adhesion and water resistance when a plurality of uncured coating films are cured at once, and especially when cured at low temperature. The method includes the following steps 1-1 to 1-4: step 1-1: coating an article with a primer coating composition (X) and forming an uncured primer coating film on the article, step 1-2: a coating the article having the uncured primer coating film with an aqueous colored coating composition (Y1) for a base coat, to form an uncured base coat film thereover, step 1-3: coating the article having the uncured primer coating film and uncured base coat film, with a clear coating composition (Z), and forming an uncured clear coating film thereover, and step 1-4: a curing the uncured primer coating film, the uncured base coat coating film and the uncured clear coating film by heating.Type: GrantFiled: February 22, 2013Date of Patent: August 30, 2016Assignee: KANSAI PAINT CO., LTD.Inventors: Minoru Ishikura, Takashi Nakayabu, Yuuki Yamada, Masami Kobata

Patent number: 9404010Abstract: An object of the present invention is to provide a method for forming a multilayer coating film, capable of achieving excellent curability under low-temperature, short-time conditions, and forming a multilayer coating film having excellent chipping resistance and an excellent finished appearance. This method comprises sequentially applying an aqueous first colored coating composition (X), an aqueous second colored coating composition (Y), and a clear coating composition (Z) to a substrate, and simultaneously bake-curing the resulting multilayer coating film. In this method, the aqueous first colored coating composition (X) comprises an aqueous film-forming resin (A) and a specific blocked polyisocyanate compound (B), and the clear coating composition (Z) comprises a hydroxy-containing acrylic resin (K) having a hydroxy value in a specific range, a polyisocyanate compound (L), and an organometallic catalyst (M) containing a metal compound (M1) selected from a specific range and an amidine compound (M2).Type: GrantFiled: June 24, 2013Date of Patent: August 2, 2016Assignee: KANSAI PAINT CO., LTD.Inventors: Naoyuki Iwata, Fumio Yamashita, Minoru Ishikura, Takashi Nakayabu, Kazushi Konishi, Toshiaki Morita, Masami Kobata

Publication number: 20120208035Abstract: An object of the present invention is to provide an aqueous coating composition comprising an (A) aluminium pigment treated with molybdic acid and a (B) condensed polycyclic pigment. The aqueous coating composition can achieve a small difference between the color of a coating film formed by application of the coating composition after storage and a color of the coating film formed by application of the coating composition before storage. The aqueous coating composition of the present invention inhibits hydrogen gas generation, and thus has excellent storage stability. The present invention provides an aqueous coating composition, comprising: (A) aluminium pigment treated with molybdic acid; (B) condensed polycyclic pigment; (C) resin having an aromatic ring with a nitro group bonded thereto; and (D) film-forming resin.Type: ApplicationFiled: September 29, 2010Publication date: August 16, 2012Inventors: Toru Iwamoto, Chihiro Nagano, Takashi Nakayabu, Keiji Sugamoto, Hideo Sugai
