Patent number: 8912264Abstract: It is an object of the present invention to provide an aqueous ethylene-vinyl alcohol-based copolymer dispersion which is excellent in long-term storage stability and in film-forming properties even when subjected to low-temperature or short-time drying or applied to give thick coats and can give coatings showing high gas barrier performance. The prevent invention is an aqueous ethylene/vinyl alcohol-based copolymer dispersion, which comprises: (A) an ethylene/vinyl alcohol-based copolymer with an ethylene content of 15-65 mole percent and a degree of saponification of not lower than 80 mole percent, (B) a base-neutralized ethylene/?,?-unsaturated carboxylic acid-based copolymer and (C) a polyvinyl alcohol with a degree of saponification of 75-100 mole percent and a degree of polymerization of 100-3500, the content of the polyvinyl alcohol (C) being 0.5-100 parts by weight per 100 parts by weight of the ethylene/vinyl alcohol-based copolymer (A).Type: GrantFiled: November 25, 2005Date of Patent: December 16, 2014Assignees: Sumitomo Seika Chemicals Co., Ltd., Kuraray Co., Ltd.Inventors: Yuhei Funabiki, Norihiro Sugihara, Kazutoshi Terada, Yukio Ozeki, Michiyuki Nanba

Patent number: 8546491Abstract: The present invention provides a polyolefin-based composite resin spherical particle that gives a coating film having a matte appearance, a soft feeling, and excellent scratch resistance by being used for a coating material. The present invention also provides a coating composition containing the polyolefin-based composite resin spherical particle and a coating resin, and a coated article obtained by applying the coating composition to a substrate. The invention relates to a polyolefin-based composite resin spherical particle, which is a spherical particle obtained by mixing 100 parts by mass of a polyolefin-based resin, 40 to 1,500 parts by mass of water, and 3 to 30 parts by mass of an ethylene oxide/propylene oxide copolymer having a weight average molecular weight of 4,000 to 30,000 to prepare a mixture, emulsifying the mixture at a temperature of the highest melting point of the polyolefin-based resin or higher, and cooling the mixture from a temperature at least 25° C.Type: GrantFiled: September 2, 2010Date of Patent: October 1, 2013Assignee: Sumitomo Seika Chemicals Co., Ltd.Inventors: Yuhei Funabiki, Toshiaki Fujiwara, Hirofumi Fujita
