Abstract
The present invention relates to a method for producing titanium oxide (TiO,)-tin oxide (SnO,) composite sol, a titanium oxide (TiO,)-zirconium oxide (ZrO,)-tin oxide (SnO,) composite sol, and a titanium oxide (TiO,)-cerium oxide (CeO,)-tin oxide (SnO,) composite sol. Further, the present invention relates to a coating composition containing any of the above-mentioned composite sols for forming coating films that are excellent in marring resistance, surface hardness, wearing resistance, transparency, heat resistance, light-resistant, weatherability, or water resistance on optical elements such as lenses for glasses and cameras, automotive windowpane, or optical filters attached to liquid-crystal displays, plasma displays, etc. and to optical elements having a cured film of the coating composition on the surfaces.
