The fine particles are coated with films including a first coupling agent having a first coupling reactive group that undergoes a coupling reaction with the first functional group to form a bond. The fine particle layer is bound by a bond formed through a coupling reaction. In an embodiment, fine particles coated with films of a film compound that reacts with the first coupling reactive group and the fine particles are alternately bound to the substrate.Type: ApplicationFiled: March 7, 2008Publication date: June 10, 2010Inventor: Kazufumi Ogawa

Publication number: 20100105844Abstract: A composition includes a siloxane of the formula: (RMe2Si01/2)a(MeRSi02/2)b(RSi03/2)o(Si04/2)d wherein a is at least 2, b is from 3 to 20, c is from 0 to 10, d is from 0 to 10, and each R is independently of the formula —CR?2-CR?2-Y—Z or —CRVCRVZ, wherein each R1 is independently a hydrogen atom or a Ci to C1O hydrocarbyl free of aliphatic unsaturation so long as at least one R? is a hydrogen atom, Y is a divalent organic group, and Z is a polycyclic group containing at least one aromatic ring. A method of making the siloxane includes charging (HMe2SiO i/2)a(MeHSi?2/2)b(HSi?3/2)c(Si?4/2)d, a platinum catalyst, and an alkene of the formula CR2=CR—Y—Z or CR2=CR—Z into a reactor to form the siloxane. The siloxane is useful as a component in holographic storage media for photopolymer-based holographic data storage applications. The siloxane exhibits excellent compatibility when mixed with a polymerizable component before the polymerizable component is cured.Type: ApplicationFiled: April 10, 2007Publication date: April 29, 2010Inventors: Kai Su, Duane R.

ORGANIC POLYSILOXANE, ADHESIVE COMPOSITION COMPRISING THE SAME, AND RUBBER STIFFENER TREATED THEREBY
Publication number: 20100092777Abstract: The present invention relates to a novel polymer, an adhesive composition including the same, and a rubber reinforcing material treated with the same, and more particularly to an organic polysiloxane including a certain repeating unit, an adhesive composition including the same, and a rubber reinforcing material treated with the same. Because the organic polysiloxane and the adhesive composition including the same is superior in reactivity to a hydroxyl group, an amide group, or an amine group, and has high thermal resistance and low stiffness, the composition is preferably used for surface-treating a rubber reinforcing material such as a tire cord and make it possible to provide a rubber reinforcing material such as a tire cord having good properties.Type: ApplicationFiled: March 6, 2008Publication date: April 15, 2010Applicant: Kolon Industries Inc.Inventors: Jae-Woong Lee, Young-Se Oh, Gi-Woong Kim -
Publication number: 20100041823Abstract: The invention provides novel siloxane monomers useful in a variety of adhesive applications. In one aspect, the siloxane compounds described herein can be used as Diels-Alder type curatives for bismaleimide or poly-maleimide monomers. The unsaturated resins shown here are attractive for use as maleimide curatives due to their poly-functionality. Each substituted styrenyl reside can react with two maleimide functional groups. Thus, an invention adhesive composition typically contains an excess of bismaleimide monomers.Type: ApplicationFiled: August 13, 2009Publication date: February 18, 2010Applicant: DESIGNER MOLECULES, INC.Inventor: Stephen M.
