A conductive frame is disposed on and connected to an anti-static layer of the donor substrate and frames the periphery of the donor substrate. The conductive frame is connected to a grounded stage. An organic layer is formed using LITI, and the generation of static electricity is controlled.Type: GrantFiled: August 24, 2005Date of Patent: November 13, 2007Assignee: Samsung SDI Co., Ltd.Inventors: Mu-Hyun Kim, Myung-Won Song, Byung-Doo Chin, Seong-Taek Lee

Patent number: 7282321Abstract: Disclosed is a presensitized plate composed of a support having thereon an image recording layer which includes: an infrared absorber (A) that is a cyanine dye having at least one fused ring composed of a nitrogen-containing heterocycle in combination with an aromatic ring or a second heterocycle, and having on the aromatic ring or second heterocycle an electron-withdrawing group or a heavy atom-containing group, a radical generator (B), and a radical-polymerizable compound (C), and which is removable with printing ink and/or dampening water. The presensitized of the present invention can be imaged with an infrared light-emitting laser to directly record an image from digital data on a computer or the like and is then subjected to on-machine development without carrying out a development step, which is capable of providing a large number of good impressions with a practical amount of energy.Type: GrantFiled: March 26, 2004Date of Patent: October 16, 2007Assignee: Fujifilm CorporationInventors: Tomoyoshi Mitsumoto, Ippei Nakamura, Naonori Makino

Patent number: 7226724Abstract: There is provided an alkaline soluble positive-type photosensitive composition having an infrared wavelength range laser sensitive characteristic. There is also provided a positive-type photosensitive composition not requiring any burning operation, capable of attaining a requisite and sufficient close fitness in coating operation under a condition of indoor working room humidity of 25 to 60%, capable of attaining a development not producing any residuals while keeping a high sensitivity, cutting it with a sharp contour, attaining a quite hard resist film and improving an anti-scar characteristic in a handling before developing operation. This composition includes an alkaline soluble organic high molecular substance having a phenolic hydroxyl group; photo-thermal conversion substance for absorbing infrared rays of an image exposure light source; and a close-fitness modifying agent such as polyvinylpolypirrolidone/polyvinylacetatecopolymer and the like.Type: GrantFiled: November 10, 2003Date of Patent: June 5, 2007Assignee: Think Laboratory Co., Ltd.Inventor: Tsutomu Sato

Patent number: 7226716Abstract: A thermal transfer donor element is provided which comprises a support, a light-to-heat conversion layer, an interlayer, and a thermal transfer layer. When the above donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. The construction and process of this invention is useful in making colored images including applications such as color proofs and color filter elements.Type: GrantFiled: November 10, 2005Date of Patent: June 5, 2007Assignee: 3M Innovative Properties CompanyInventors: Jeffrey C. Chang, John S. Staral, William A. Tolbert, Martin B. Wolk, Claire A. Jalbert, Hsin-hsin Chou

Patent number: RE41128Abstract: New polymers and new anti-reflective compositions containing such polymers are provided. The compositions comprise a polymer (e.g., epoxy cresol novolac resins) bonded with a chromophore (4-hydroxybenzoic acid, trimellitic anhydride). The inventive compositions can be applied to substrates (e.g., silicon wafers) to form anti-reflective coating layers having high etch rates which minimize or prevent reflection during subsequent photoresist exposure and developing.Type: GrantFiled: January 25, 2007Date of Patent: February 16, 2010Assignee: Brewer Science Inc.Inventor: Shreeram V.
