Abstract: PROBLEM TO BE SOLVED: To provide an optical film, manufacturing method thereof, and a polarizing plate using the optical film, capable of obtaining a polarizing plate in which optical leakage in crossed Nicol state is less even if observed obliquely as well as squarely, and revealing excellent polarizing characteristics. SOLUTION: The optical film is formed by fusion-extrusion of an amorphous thermo-plastic resin. The thickness of the film is less than 100 μm, with normal retardation R(0) as 10 nm or less. The retardation Rs(40) and Rf(40) that are measured in the direction inclined 40 deg. toward phase-advancing axis and phase- lagging axis, respectively, from the normal direction of the film are R(0)+6 nm or less, with dislocation of optical axis as ±10 deg. or less. The resin of the film is a norbornene-based resin. Related to the method of manufacturing the optical film, the temperature of film just before the contact point to a cooling roll is 'Tg of the resin' + 50 deg.C or above when the film of the resin extruded into a sheet is brought into tight contact with the cooling roll. Related to the polarizing plate, the optical film is laminated at least on one side of a polarizer.

Filed: 2002-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for producing cationic resin silica dispersion, by which the cationic resin silica dispersion can be produced in good productivity with low energy.  <P>SOLUTION: This method for producing the cationic resin silica dispersion comprises mixing the silica dispersion in a polar solvent where silica has an average particle diameter of <300 nm, with the aqueous solution of a cyclic ammonium cationic resin having an average mol.wt. of ≤50,000. The silica dispersion is preferably obtained by preliminarily dispersing wet silica or dry silica and then subjecting the pre-dispersion to a grinding dispersion treatment using a high pressure homogenizer. The produced cationic resin silica dispersion hardly causes the flocculation of the silica, even when the mixture is not subjected to the grinding dispersion treatment.  <P>COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a fractal structure that can realize a heterojunction or a phase separation by a simple design method exceeding a fractal property. SOLUTION: This fractal structure is formed so that the structure may have at least one heterojunction formed of two areas having different fractal dimensions characterizing the self-similarity of the areas. In a radial fractal structure, particularly, the heterojunciton is formed by forming an area (dendritic area) having a low fractal dimension around a core (somatic area) having a high fractal dimension. The two areas forming the heterojunction have different phases, for example, a ferromagnetic phase and a paramagnetic phase or a metallic phase and a Mott insulation phase. A functional material or a functional element is realized by using this fractal structure.
