Patent number: 8188185Abstract: A biodegradable packaging film is provided. The film is formed from a blend that contains a thermoplastic starch and polylactic acid. Starch is a relatively inexpensive natural polymer that is also renewable and biodegradable. Polylactic acid is likewise an inexpensive synthetic polymer that is biodegradable and renewable, yet also capable of providing increased tensile strength to the film. Although providing a good combination of biodegradability/renewability and increased tensile strength, the polylactic acid is also relatively rigid and can result in films having a relatively high stiffness (e.g., high modulus of elasticity) and low ductility. While more ductile than polylactic acid, the thermoplastic starch is often difficult to melt process in film forming processes and very sensitive to moisture and water vapor, reducing its ability to be used as a stand alone packaging film.Type: GrantFiled: June 30, 2008Date of Patent: May 29, 2012Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James H.

Publication number: 20120077911Abstract: The present invention relates to an aqueous coating material containing polymer (I), colloidal silica (II), and nonionic surfactant (III) with an HLB value of 16 or more. The polymer (I) is obtained by copolymerization of monomer mixture (M) that contains 0.2 to 10% by mass of monomer (a) having two or more radically polymerizable groups. The solid content of the colloidal silica (II) is 0.1 to 20 parts by mass with respect to 100 parts by mass of the polymer (I). The content of the nonionic surfactant (III) is 0.01 to 10 parts by mass with respect to 100 parts by mass of the polymer (I). The present invention also relates to a painted article where the aqueous coating material is applied. Therefore, an aqueous coating material and a painted article capable of expressing stain resistance and weather resistance can be provided by reducing a water contact angle.Type: ApplicationFiled: June 8, 2010Publication date: March 29, 2012Applicant: MITSUBISHI RAYO CO., LTD.Inventors: Shinsuke Haraguchi, Motomi Tanaka, Junichi Nakamura, Daisuke Natsui
