GLASS ARTICLE HAVING ULTRAVIOLET RAY SHIELDING PERFORMANCE, AND MICROPARTICLES-DISPERSED COMPOSITION FOR FORMING ULTRAVIOLET RAY SHIELDING FILM

摘要

An ultraviolet shielding film according to the present invention includes a silicon oxide and fine particles of an organic compound A that is solid at ordinary temperature and that has a molecular weight of 5,000 or less, the fine particles having an average particle diameter of 150 nm. A glass article of the present invention has an ultraviolet transmittance (TUV 380) of, for example, 2% or less, and preferably further has a light transmittance (T 550) more than 70% at a wavelength of 550 nm. The ultraviolet shielding film may further include an organic compound B such as a polyether compound and a polyol compound. The ultraviolet shielding film is excellent in the sustainability of the ultraviolet shielding ability.
