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

摘要

This ultraviolet ray shielding film contains silicon oxide and microparticles of an organic compound (A) having a solid form at ambient temperature and having a molecular weight of 5000 or less, wherein the microparticles have an average particle diameter of 150 nm or less. The glass article has, for example, an ultraviolet ray transmittance (TUV380) of 2% or less, and preferably also has a transmittance (T550) for light having a wavelength of 550 nm of more than 70%. The ultraviolet ray shielding film may additionally contain an organic compound (B) such as a polyether compound and a polyol compound. The ultraviolet ray shielding film has excellent long-term ultraviolet ray shielding performance.
