PURPOSE:To improve resistance against high or low temperature and resistance against moisture and water, and chemical resistance by dispersing transparent particles having a specified average particle size in a transparent silica or silicone-compound film base material to form an antidazzle film. CONSTITUTION:This film is formed by dispersing transparent particles of 1-10mum average particle size by 0.5-10wt.% in a transparent silica or silicone-compound film base material. In this case, it is preferable that the transparent particles consist of transparent glass material, single crystal, or transparent synthetic resin. A polycrystalline material may be used as far as it shows small refraction or scattering of light on intergranular interfaces. The transparent particles are such material having high hardness and chemical resistance and <=2.0 refractive index, and preferably <=1.7, essentially comprising silica, alumina, or magnesia, glass powder such as soda glass, borosilicate glass, etc., or org. material of natural or synthetic resin. |
