Publication number: 20030078326Abstract: Novel ultraviolet absorbing compounds that are liquid in nature, are extremely low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat such discoloring), and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. In addition, such ultraviolet absorbers also exhibit extremely low migratory properties thereby providing long-term protective benefits to the target media as well.Type: ApplicationFiled: August 21, 2001Publication date: April 24, 2003Inventors: Xiaodong E.

Publication number: 20030065069Abstract: Cyanoacrylate composition, having a cure indicator within the composition, is disclosed herein. The cyanoacrylate composition is “self-indicating” with respect to its ability to allow the end user to visually inspect the composition to determine whether, and the extent to which, cure has occurred. The composition includes a cyanoacrylate component, and a dye dissolved in the cyanoacrylate component. The cyanoacrylate composition has an initial color, oftentimes colorless or substantially so to the naked eye, and when cured, the cured cyanoacrylate composition has a different or second color. Observation of the second or different color is indicative that cure has occurred and the extent of the color change can be used to determine the degree of cure that has occurred.Type: ApplicationFiled: January 18, 2002Publication date: April 3, 2003Applicant: LOCTITE CORPORATIONInventor: Stan Wojciak

Patent number: 6492441Abstract: The present invention relates to organic anti-reflective coating polymers and preparation methods therefor. Anti-reflective coatings are used in a semiconductor device during photolithography processes to prevent the reflection of light from lower layers of the device, or resulting from changes in the thickness of the photoresist layer, and to eliminate the standing wave effect when ArF light is used. The present invention also relates to anti-reflective compositions and coatings containing these organic anti-reflective coating polymers, alone or in combination with certain light-absorbing compounds, and preparation methods therefor.Type: GrantFiled: December 11, 2001Date of Patent: December 10, 2002Assignee: Hyundai Electronics Industries Co., Ltd.Inventors: Sung-Eun Hong, Min-Ho Jung, Hyeong-Soo Kim, Ki-Ho Baik
