Patent number: 6825261Abstract: An antistatic coat of the present invention coats a surface of a base body so as to prevent accumulation of electric charges in the base body, the antistatic coat having a multi-layers structure comprising at least one antistatic layer, and the antistatic layer being disposed between the base body and an outermost surface layer of the antistatic coat. On the back surface side of a thermal transfer sheet, there is formed a heat resistant slip layer through an antistatic layer, or a heat resistant slip layer containing a conductive material. Sulfonated polyaniline, a conductive carbon black having primary particle size of up to 40 nm and specific surface of at least 130 m2/g, and a conductive carbon black having an oil absorption of at least 75 ml/100 g are favorable conductive material.Type: GrantFiled: August 30, 2001Date of Patent: November 30, 2004Assignee: Dai Nippon Printing Co., Ltd.Inventors: Akihiko Katashima, Norikatsu Ono, Masayuki Ando, Shigeki Chujo, Masayoshi Tanaka

Patent number: 6113836Abstract: A female mold (2, 12, 22, 32, 42, 52, 62) having a desirable pattern is formed on a substrate (1, 11, 21, 31, 41, 51, 61). Next, ceramic material (3, 13, 23, 33, 43, 53, 63) is filled in spaces in the female mold. Thereafter, the female mold is removed by heating the entire substrate, whereby a desirable thick film pattern can be finely and easily formed. The inorganic paste material comprising inorganic liquid vehicle containing water glass as main ingredient and powdery solid dispersed in the inorganic liquid vehicle is used as the ceramic material. The volume change of the inorganic paste material is small during the drying and calcinating processes, thus the inorganic paste material is prevented from being broken.Type: GrantFiled: June 22, 1998Date of Patent: September 5, 2000Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Yorihiko Sakai, Norikatsu Ono, Norikazu Mineo, Takeshi Matsumoto, Hideaki Fujii

Patent number: 6057900Abstract: A color liquid crystal display device contains a color filter substrate, a counterelectrode substrate disposed to oppose the color filter substrate via a sealing material disposed in contact with peripheral portions of the color filter substrate and the counterelectrode substrate, and a liquid crystal layer sealed between the color filter substrate and the counterelectrode substrate and surrounded by the sealing material. The color filter substrate contains a transparent substrate, a black matrix and a plurality of colored layers of plural colors, the black matrix and the colored layers being formed in a predetermined pattern in a first region on the transparent substrate, and a resin layer having substantially same thickness as that of the black matrix and formed in a second peripheral region on the transparent substrate positioned peripherally adjacent to the first region. The sealing material is in contact with the resin layer and a black matrix portion in periphery of the first region.Type: GrantFiled: July 10, 1998Date of Patent: May 2, 2000Assignees: Dai Nippon Printing Co., Ltd., Nippon Oil Co., Ltd.Inventors: Norikatsu Ono, Masayuki Ando, Yutaka Otsuki, Hiroyoshi Omika

Patent number: 5718992Abstract: A method for preparing a substrate having a light-shielding layer involves forming a photosensitive coating film on a transparent electrically conductive layer formed on a transparent substrate, exposing the photosensitive coating film via a mask exhibiting light transmitting properties, removing and developing the coating film for exposing the transparent electrically conductive layer and electrodepositing a dark-hued coating on the exposed transparent electrically conductive layer for forming the light-shielding layer, and heating the light-shielding layer. The substrate having the light-shielding layer has a volume resistivity of 1.times.10.sup.2 ohm.cm or higher and may be used for a counterelectrode substrate for a TFT array substrate incorporated in a liquid crystal display device.Type: GrantFiled: November 6, 1996Date of Patent: February 17, 1998Assignee: Dai Nippon Printing Co., Ltd.Inventors: Haruyoshi Sato, Toru Nakamura, Hitoshi Yuasa, Yutaka Otsuki, Hiroyoshi Omika, Norikatsu Ono, Tadafumi Shindo
