Patent number: 5622778Abstract: A synthetic resin composition comprises an aqueous medium, a surfactant, and a resin and filler dispersed in the aqueous medium by the surfactant. The surfactant comprises a first high molecular weight compound having a weight-average molecular weight of at least 10000 and a second high molecular weight compound having a weight-average molecular weight of not less than 150 and less than 10000. In the synthetic resin composition, a solid material is well dispersed and the viscosity doesn't remarkably increase even if a solid content is increased. So, the increased amount of a non-volatile matter may be used and the storage stability improves. Further, flame retardation, deodorization, heat resistance and light fastness also improve. In addition, an interior material which is a fabric coated with the synthetic resin composition is provided. In the interior material, the texture, flame retardation, deodorization and light fastness improve without the deterioration of workability.Type: GrantFiled: January 26, 1996Date of Patent: April 22, 1997Assignees: Kabushiki Kaisha Toyota Chuo Kenkyusho, Toyota Jidosha Kabushiki Kaisha, Toyoda Boshoku Corporation, Dainippon Ink and Chemicals, IncorporatedInventors: Mitsumasa Horii, Masahiro Sugiura, Seiji Onoda, Yoshio Yamada, Osamu Araki, Yoshiro Umemoto, Kazuo Ito, Takatoshi Sekihara, Akihiro Matsuyama, Masaaki Izumichi, Kiyoshi Umehara, Reizaburo Tomioka
