Patent number: 7264918Abstract: A resist composition for liquid immersion lithography process, which comprises: (A) a polymer comprising (a1) alkali-soluble constitutional units each comprising an alicyclic group having both (i) a fluorine atom or a fluoroalkyl group and (ii) an alcoholic hydroxyl group, wherein the polymer changes in alkali-solubility due to the action of acid; and (B) an acid generator which generates acid due to exposure to light, and a method for forming a resist pattern using the resist composition. By the resist composition or the method, an adverse effect of the immersion liquid can be avoided while achieving high resolution and high depth of focus.Type: GrantFiled: March 24, 2004Date of Patent: September 4, 2007Assignee: Tokyo Ohka Kogyo Co., Ltd.Inventors: Kotaro Endo, Masaaki Yoshida, Taku Hirayama, Hiromitsu Tsuji, Toshiyuki Ogata, Mitsuru Sato

Patent number: 7244546Abstract: A planographic printing plate precursor includes a substrate and an image recording layer provided thereon, the image recording layer being capable of recording through exposure to an infrared ray and containing at least (A) an infrared absorbing agent, (B) a polymerization initiator comprising an onium salt formed by an onium cation and a carboxylic acid anion, where the carboxylic acid anion has an acid group, a hetero atom and an aromatic group, (C) a polymerizable compound and (D) a binder polymer. The planographic printing plate precursor is exposed imagewise with an infrared laser. Then, printing is carried out using the exposed planographic printing plate precursor, which is set in a printer without being subjected to any developing process, by feeding an oil based ink and an aqueous component onto the planographic printing plate precursor. Unexposed areas of the planographic printing plate precursor are removed during the printing process.Type: GrantFiled: June 16, 2005Date of Patent: July 17, 2007Assignee: Fujifilm CorporationInventors: Kazuto Shimada, Tomoyoshi Mitsumoto

Patent number: 7232649Abstract: An improved method of manufacturing a photosensitive printing element that minimizes relief variation and improves image fidelity. The method involves a step of pre-curing the first (floor layer) of photocurable material prior to depositing an additional layer or layers of photocurable material that may be imaged and developed to produce a desired relief image on the surface of the photosensitive printing element. The photosensitive printing element is then thermally developed by contacting the photosensitive printing element with at least one roll that is capable of moving over at least a portion of the imaged surface of the flexographic printing element to remove the softened or melted non-crosslinked photopolymer.Type: GrantFiled: May 23, 2006Date of Patent: June 19, 2007Inventor: Ryan Vest
