Publication number: 20190016932Abstract: A laminate includes a resin substrate, an intermediate layer disposed on a surface of the resin substrate, and a silicon oxide layer disposed on a surface of the intermediate layer. The intermediate layer is formed by curing a composition containing a Si-free compound containing a (meth)acrylic group and a siloxane compound containing a (meth)acrylic group. A concentration of Si is higher on a silicon oxide layer side than a concentration of Si on a resin substrate side in the intermediate layer.Type: ApplicationFiled: July 10, 2018Publication date: January 17, 2019Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Hidenori MUNEKATA, Yuya MARUYAMA, Hisashi MURAMATSU, Tetsuya MITSUOKA

Patent number: 9604250Abstract: Disclosed is a method for repairing a damaged area of a silicone hard-coat layer on an automotive resin glazing substrate by applying an intermediate coating composition (I) to the damaged area and applying a topcoat coating composition (II) to the intermediate coating composition. The intermediate coating composition (I) contains (A) a reactive siloxane compound and (B) silica. The topcoat coating composition (II) contains (C) an alkoxysilane having a UV-absorbing functional group, (D) a multifunctional alkoxysilane, (E) a reactive siloxane compound, (F) colloidal silica, and (G) phosphoric acid. The method forms a coating having the same appearance and physical properties as the underlying silicone hard-coat layer.Type: GrantFiled: November 18, 2014Date of Patent: March 28, 2017Assignees: SHIN-ETSU CHEMICAL CO., LTD., KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Motoo Fukushima, Yukimasa Aoki, Masahiro Yoshizawa, Koichi Chigita, Yuya Maruyama, Hidenori Munekata
