TRANSPARENT MOLDING HAVING LOW REFLECTIVITY AND ELECTRICAL CONDUCTIVITY

摘要

PURPOSE:To obtain the transparent molding having antireflection and antistatic properties and scratching resistance by providing two layers; a specific conductive layer consisting of inorg. fine particles and a high-refractive index layer on an air side on the surface of the molding. CONSTITUTION:The two layers; the conductive layer consisting of the inorg. fine particles and having <=10<10>(OMEGA/square) surface resistance value and the high- refractive index layer having >=0.1 refractive index difference from the refractive index of the conductive layer are provided on the air side on the surface of the molding formed of a transparent base material. The interference effect of light is utilized by adjusting the refractive indices and film thickness of the two layers; the conductive layer and the high-refractive index layer in this case; in addition, the layer contg. a material having an electrical conductivity is provided. The low reflectiveness is obtd. in this way and the electrical conductivity is obtd. as well. Since the fine particles of the metal oxide are used as the conductive material, the surface scratching resistance and durability are obtd.
