Patent number: 8303704Abstract: A siloxane based coating composition having excellent dyeability, abrasion resistance, glossiness and transparency, a preparation method thereof, and an optical lens coated by the coating composition are suggested. The siloxane based coating composition includes organo silane compound, inorganic oxide (H-index filler), solvent and a dyeing improving material. The dyeing improving material adopts nitric acid, hydrochloric acid, phosphoric acid, sodium nitrate, potassium nitrate, silver nitrate, or the like. The siloxane based coating composition shows excellent dyeability owing to the dyeing improving material, excellent abrasion resistance owing to the organo silane compound, and excellent glossiness and transparency, so it may be applied as a coating film on a surface of a plastic lens such as optical lens, industrial safety lens and leisure-purpose goggle that require high transparency.Type: GrantFiled: November 15, 2007Date of Patent: November 6, 2012Assignee: LG Chem, Ltd.Inventors: Sang-Hyuk Im, Do-Hyun Jin, Jong-Pyo Kim, Young-Jun Hong, Seung-Heon Lee

Patent number: 8293000Abstract: An antireflective coating composition includes a hydrolytic condensate (C1) of alkoxy silane (C11) and fluoric alkoxy silane (C12); a particle-type metal fluoride (C2) with a refractive index of 1.40 or less; and a liquid dispersion-enhancing chelating agent (C3). A coating film to which the above composition is applied controls refractive index, surface energy, film strength and so on, so it ensures excellent antireflective characteristic, excellent scratch resistance, good erasure of liquid stains such as fingerprints, and particularly excellent dust removal, so it may be usefully applied to an outermost layer of a front surface of a display regardless of kind of a display substrate or presence of an additional coating layer.Type: GrantFiled: July 6, 2007Date of Patent: October 23, 2012Assignee: LG Chem, Ltd.Inventors: Joon-Koo Kang, Mi-Young Han, Young-Eun Lee, Young-Jun Hong, Yeong-Rae Chang

Publication number: 20120192762Abstract: Fine mesoporous silica particles are provided by which not only the functions of low reflectance (Low-n), low dielectric constant (Low-k) and low thermal conductivity but also improved strength of a molded article are achieved. The fine mesoporous silica particles are manufactured by a process including a surfactant composite fine silica particle preparation step and a mesoporous particle formation step. In the silica fine particle preparation step, a surfactant, water, an alkali and a hydrophobic part-containing additive including a hydrophobic part for increasing the volume of micelles are mixed with a silica source to thereby prepare surfactant composite fine silica particles. In the mesoporous particle formation step, the mixture is mixed with an acid and an organosilicon compound to thereby remove the surfactant and hydrophobic part-containing additive from the surfactant composite fine silica particles and provide the surface of each silica fine particle with an organic functional group.Type: ApplicationFiled: May 18, 2010Publication date: August 2, 2012Applicants: THE UNIVERSITY OF TOKYO, Panasonic CorporationInventors: Hiroki Yabe, Takeyuki Yamaki, Yasuto Hoshikawa, Tatsuya Okubo, Atsushi Shimojima
