Patent number: 6203890Abstract: A co-winding type thermal transfer sheet is constituted by forming on one surface side of a substrate film a heat-fusible ink layer comprising a pigment and a particulate binder, and causing a tracing paper to be peelably bonded onto the heat-fusible ink layer by the medium of an adhesive layer. The thus constituted co-winding type thermal transfer sheet is capable of providing an original image which can be reproduced by use of a blueprint process so as to provide blueprint images having a high precision and a high contrast. In addition, a co-winding type thermal transfer sheet may also be constituted by forming a heat-fusible ink layer on one surface side of a substrate film and causing a transparent resin sheet to be peelably bonded onto the heat-fusible ink layer by the medium of an adhesive layer containing a cross-linking agent. The thus constituted co-winding type thermal transfer sheet is capable of providing an image excellent in wear resistance on the transparent resin sheet.Type: GrantFiled: February 8, 2000Date of Patent: March 20, 2001Assignee: DAI Nippon Printing Co., Ltd.Inventors: Hirokatsu Imamura, Masafumi Hayashi, Kouichi Nakamura, Hirokazu Kaneko, Shigeki Umise, Kenichiro Suto, Hiromi Watanabe

Patent number: 5593940Abstract: A thermal transfer sheet having a back coating layer excellent in heat-resistance is provided by using a styrene-acrylonitrile copolymer as a resin constituting the back coating layer. A thermal transfer material having an excellent heat-resistance and having a back coating layer having considerable strength is provided by incorporating at least two species of heat-resistant particles having different particle sizes in the back coating layer, since the larger species of particle imparts excellent heat-resistance to the back coating layer, the smaller species of particle enhances the total amount of the fillers, and the larger and smaller species of particles function so as to provide a synergistic effect.Type: GrantFiled: November 17, 1994Date of Patent: January 14, 1997Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Shigeki Umise, Taro Suzuki, Kyoichi Yamamoto

Patent number: 5441567Abstract: A strip or roll of thermal transfer type recording sheet has a base film on one side of which a hot-melt ink layer is formed for recording on paper or other surface by thermal transfer. An end mark or marks to be detected optically for warning the user of the fact that the recording roll is being used up is/are formed adjacent one end of the strip by gravure printing with use of a light-reflective ink. The end mark or marks produced by gravure printing are of such constant thickness, and with the bounding edges so sharply defined, that they permit positive detection by an optical sensor.For the production of the end marks by gravure printing, a web of base film with the hot-melt ink layer formed on one side thereof, with a width several times greater than that of each strip of recording sheet to be manufactured, is fed through a printing unit of a gravure printing section.Type: GrantFiled: October 30, 1992Date of Patent: August 15, 1995Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Shigeki Umise, Hirokatsu Imamura

Patent number: 5376432Abstract: There is used, as a substrate film, a polypropylene film having a tear strength in the range of 15 to 40 Kg with respect to an MD direction and a TD direction thereof; an elongation in the range of 40 to 200 with respect to the MD direction and the TD direction thereof; and a Young's modulus in the range of 200 to 600 Kg/mm.sup.2 with respect to the MD direction and the TD direction thereof, and a transferable ink layer is formed on a surface of such a substrate film. When the resultant thermal transfer sheet having such a structure is used, a printing pressure based on a thermal head is sufficiently transmitted to a transfer receiving material, and therefore it is possible to form an image of good quality on the transfer receiving material even when the transfer receiving material comprises a plain paper having a relatively rough texture (or relatively coarse grain).Type: GrantFiled: November 27, 1991Date of Patent: December 27, 1994Assignee: Dai Nippon Printing Co., Ltd.Inventors: Shigeki Umise, Taro Suzuki
