Publication number: 20080268236Abstract: The object of the present invention is to provide a laminated glass which has fundamental characteristics required of laminated glass, and which shows a bright color when viewed from the exterior but shows substantially the same color as the color of an interior glass sheet itself when viewed from the interior. The laminated glass comprises a laminate of two glass sheets and an interlayer interposed between the glass sheets. One of the glass sheets arranged on the exterior side in use is a tinted transparent glass sheet and the other glass sheet arranged on the interior side in use is a visible light reflective glass sheet. The interlayer comprises fine particles of tin-doped indium oxide (ITO).Type: ApplicationFiled: June 12, 2006Publication date: October 30, 2008Inventors: Tadashi Marumoto, Kunio Mitoma
