Patent number: 7045001Abstract: A multi-component kit and method is provided to pretreat, resurface, and restore a plastic material, and in particular, the plastic lens covers over the headlights and taillights of an automobile. The multi-component kit includes a pretreatment formulation, a resurfacing formulation, and a restoration formulation. Each formulation is structured for application to the plastic lens covers by hand, thereby eliminating the need for specialized equipment or training. The method includes application of each formulation to the plastic lens covers using clean, lint free applicators. The pretreatment formulation is applied to clean the plastic lens covers and to prepare them for application of the resurfacing formulation, which repairs scratches and removes discoloration. The restoration formulation is applied to restore a high gloss shine to the plastic lens covers as well as to protect the plastic lens covers from the elements such as dust, dirt, and/or ultra-violet radiation.Type: GrantFiled: November 4, 2002Date of Patent: May 16, 2006Inventors: Stacy Kropp, Jeremy Drake, Victor Winik

Patent number: 7045257Abstract: The present invention provides a black matrix containing metal fine particles, wherein the volume fraction of the metal fine particles is in a range from 0.05 to 0.70. The volume fraction is preferably is in a range from 0.10 to 0.55, and more preferably in a range from 0.2 to 0.50. The invention also provides a method of manufacturing the black matrix. The method is preferably a method comprising: forming a recording material having a layer formed by applying and drying a coating liquid containing metal fine particles on a temporary support; and transferring the layer onto a substrate. Further, the invention also provides a method comprising the step of applying onto or above the substrate the coating liquid containing the metal fine particles and then drying the coating liquid. In each of the methods, the coating liquid can have photosensitivity.Type: GrantFiled: April 16, 2004Date of Patent: May 16, 2006Assignee: Fuji Photo Film Co., Ltd.Inventors: Akira Hatakeyama, Hidenori Gotoh, Hideaki Ito

Patent number: 7037573Abstract: An antireflection layer is formed directly or through an other layer at least on one side of a transparent base film of an antireflection film. The antireflection layer is made of at least two kinds of low refractive index materials satisfying a relationship of refractive index: nd20?1.49. The antireflection layer is excellent in antireflection characteristics and mar resistance. When the antireflection layer is formed on a hard coat layer having an uneven surface roughened by particles, the antireflection film is excellent in antiglareness.Type: GrantFiled: March 12, 2003Date of Patent: May 2, 2006Assignee: Nitto Denko CorporationInventors: Minoru Miyatake, Masahiro Yoshioka, Tomoaki Masuda, Atsushi Kitagawa, Hiroyuki Takao, Kaori Shirouzu

Patent number: 7014964Abstract: A color filter substrate comprising a substrate, a black matrix and a plurality of color filter patterns is provided. The black matrix is disposed on a rough surface of the substrate to define a plurality of sub-pixel regions. Each one of the color filter patterns is disposed in one of the sub-pixel region and touch the rough surface. When the color filter patterns are formed in the sub-pixel regions, the contacting area between the color filter patterns and the substrate is increased owing to the rough surface of the substrate. Thus, the adhesion between the color filter patterns and the substrate within the sub-pixel regions are enhanced.Type: GrantFiled: November 25, 2004Date of Patent: March 21, 2006Assignee: Chunghwa Picture Tubes, LTD.Inventors: Feng-Lin Hsu, Yu-Cheng Lo

Patent number: 7002661Abstract: Polarizing coatings are formed from dyestuffs which provide a stable liquid crystalline phase in a wide range of concentrations, temperatures and pH-values. Particles formed by aggregates of the liquid crystal molecules are oriented in a predetermined direction to polarize light The stability of the liquid crystalline state allows orienting the particles by mechanical forces such as a shearing force applied when the liquid crystal (10) is spread on a support surface (20) by a knife-like doctor (90) or a tension deformation force acting on the meniscus of the liquid crystal deposited between two surfaces (20, 30) as the surfaces are peeled off one another. As a result, the polarizing coatings are formed in some embodiments by simple methods. In some embodiments, the polarizing coatings have a high lightfastness, a high thermal stability, and a high dichroic ratio.Type: GrantFiled: July 12, 2001Date of Patent: February 21, 2006Assignee: TECDIS S.p.A.Inventors: Christian Scarabelli, Corrado Gerbaz
