The coating composition is substantially free of a lead component and comprises (a) a vehicle containing a synthetic resin, (b) a first salt formed by a neutralization of an acid with a base containing a second metal having an ionization tendency that is greater than the silver and the first metal, and (c) a basic compound selected from the group consisting of azoles and diamines. The acid is one compound selected from the group consisting of organic acids each containing an azole ring and unsubstituted and substituted carbamic acids.Type: GrantFiled: March 27, 1997Date of Patent: September 2, 2003Assignee: Central Glass Company, LimitedInventors: Motoyuki Sakatoku, Kenichi Hayashi, Yoshihisa Tamura, Yutaka Mori

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

Patent number: 6458872Abstract: Benzotriazole UV absorbers which are substituted at the 5-position of the benzo ring by an electron withdrawing group exhibit enhanced durability and very low loss rates when incorporated into automotive coatings. This is particularly the case when the 3-position of the phenyl ring is also substituted by phenyl or phenylalkyl such as &agr;-cumyl. Compounds where the 5-position of the benzo ring are substituted by perfluoroalkyl such as trifluoromethyl are particularly of interest for both their enhanced durability and for their excellent solubility and excellent color properties in some thermoplastic compositions when the phenyl ring is substituted at the 3-position by hydrogen or tert-alkyl.Type: GrantFiled: May 8, 2001Date of Patent: October 1, 2002Assignee: Ciba Specialty Chemicals CorporationInventors: Ramanathan Ravichandran, Joseph Suhadolnik, Mervin G.
