Publication number: 20080146680Abstract: A particulate silver powder has an average particle diameter measured by TEM observation (DTEM) of 200 nm or less, an aspect ratio of less than 2.50, and a {(DTEM)/(Dx)} of 5.0 or less (where (Dx) denotes X-ray crystallite size). The particulate silver powder has a content of each of I?, Cl?, SO42?, NO3? and CN? of 100 ppm or less. The particulate silver powder is obtained by subjecting a silver compound other than silver nitrate to reduction in an organic solvent having a boiling point of 85° C. or greater at a temperature of 85° C. or greater and in the presence of an organic protective agent.Type: ApplicationFiled: February 1, 2006Publication date: June 19, 2008Inventor: Kimitaka Sato

Patent number: 7314584Abstract: The present invention provides a polymer gel composition including: at least two polymer compounds which interact with each other to form a polymer complex; and a liquid. One of the polymer compounds forms a three-dimensional crosslinked structure, at least one other polymer compound is compatible with the liquid, and at least a portion of the compatible polymer compound is included in the three-dimensional crosslinked structure. Preferably, when the polymer complex is disassembled or decomposed by stimuli, the polymer compound forming the three-dimensional crosslinked structure changes its volume by absorbing or releasing the liquid. The three-dimensional crosslinked structure is preferably in a particle shape. An optical device using such a polymer gel composition is also provided.Type: GrantFiled: March 22, 2004Date of Patent: January 1, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Hiroaki Tsutsui, Masahiro Moriyama, Ryojiro Akashi
