Patent number: 6613818Abstract: The invention relates to a coating composition for preparing a back coating film of a mirror. This mirror serving as an anticorrosive mirror has a glass substrate, a silver mirror film that comprises silver and is formed on a back surface of the glass substrate, a metallic protective film that comprises a first metal and is formed on the silver mirror film, and the back coating film formed on the metallic protective film. 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: 6180698Abstract: A liquid chemical formulation suitable for making a thin solid polycarbonate film of highly uniform thickness is formed with polycarbonate material, a liquid that dissolves the polycarbonate, and possibly one or more other constituents. The liquid is typically capable of dissolving the polycarbonate to a concentration of at least 1% at 20° C. and 1 atmosphere. The liquid also typically has a boiling point of at least 80° C. at 1 atmosphere. Examples of the liquid include pyridine, a ring-substituted pyridine derivative, pyrrole, a ring-substituted pyrrole derivative, pyrrolidine, a pyrrolidine derivative, and cyclohexanone. In forming the polycarbonate-containing film, a liquid film (36A) of the liquid chemical formulation is formed over a substructure (30). The liquid film is processed to largely remove the liquid and convert the polycarbonate into a solid film (38).Type: GrantFiled: February 28, 1997Date of Patent: January 30, 2001Assignees: Candescent Technologies Corporation, Hewlett-Packard CompanyInventors: John D.
