Publication number: 20110123927Abstract: A photosensitive resin composition is provided. The photosensitive resin composition comprises a) an alkali-soluble polyimide resin, b) an alkali-soluble novolak resin, c) a photosensitizer, and d) an organic solvent. The photosensitive resin composition is resistant to heat and can be used to form a pattern whose lateral angles are easily controllable. A large difference in developability between exposed and unexposed portions of the photosensitive resin composition is caused when patterning. The photosensitive resin composition is advantageous in terms of sensitivity, resolution, heat resistance and adhesiveness. Particularly, the lateral angles of the pattern can be easily controlled by varying the contents of the alkali-soluble resins. Therefore, the photosensitive resin composition is useful in the formation of an insulating film pattern of an organic light emitting diode (OLED).Type: ApplicationFiled: May 20, 2009Publication date: May 26, 2011Applicant: LG CHEM, LTD.Inventors: Chan Hyo Park, Hye In Shin, Hye Ran Seong, Kyung Jun Kim, Dong Hyun Oh

Publication number: 20110111237Abstract: Disclosed is cross-linking process for cross-linking polymeric chains in a coating composition. In one embodiment the process utilizes a Hantzsch dihydropyridine reaction to form reaction products including cross-linking polymeric resin chains having beta-keto ester functions using a source of aldehyde and a source of ammonia or a primary amine to form a permanent dihydropyridine bond between the beta-keto ester functions. The novel cross-linking reaction can occur at lower temperatures compared to typical cross-linking reactions and can occur in aqueous solutions that have a neutral to mildly alkaline pH of from 6 to 11. The novel cross-linking reaction provides many advantages to performing cross-linking of polymeric chains in coating resins.Type: ApplicationFiled: May 19, 2009Publication date: May 12, 2011Inventors: Thomas S.

Patent number: 7914858Abstract: A method and apparatus for sealing disk drive housing castings and the resulting housings. A housing component of a data storage device is placed in an environment of decreased pressure where a first tank that is an autoclave is pressurized at a selected pressure and the environment is a first tank that encloses the housing component. A second tank that is an autoclave is pressurized at substantially the same pressure as the first tank while the second tank is fluidically coupled to the first tank and encloses a sealant. The sealant is applied to a surface of the component when it is under decreased pressure by transferring the sealant from the first tank to the second tank. A pressure of at least one atmosphere is further applied so that a portion of the sealant contactingly permeates voids in the housing component before the sealant is subsequently cured.Type: GrantFiled: May 4, 2004Date of Patent: March 29, 2011Assignee: Maxtor CorporationInventors: Charles deJesus, Thomas G.
