Mit einem gehärteten Film beschichtete optische Elemente
摘要
An optical element having a cured coating film on optical base material wherein the cured coating film is prepared with a coating composition comprising an organosilicon compound and modified stannic oxide - zirconium oxide composite colloidal particles which are obtainable by partially or fully coating the surface of stannic oxide - zirconium oxide composite colloidal particles with tungstic oxide - stannic oxide composite colloidal particles. The formed cured coating film is excellent in hot water resistance, and light-resistance and weathering resistance are not impaired even when the antireflection film made by vapor deposition of inorganic oxides is applied on the cured coating film.
