The anti-glare hard coat film has excellent surface hardness and anti-glare property and provides excellent visibility when the film is used for various types of displays.Field of SearchLow energy electromagnetic radiation utilized (e.g., UV, visible, IR, microwave, radio wave, actinic, laser, etc.)Benzene ring or nitrogen containing coating material Polarizer, windshield, optical fiber, projection screen, or retroreflector Glass The inorganic material primarily contains compounds containing both silicon and oxygen, or both aluminum and oxygen, or combinations thereof (e.g., silica (SiO2) organosol*, silica alcosol, talc, clay) Silicon dioxide containing Inorganic silicon compound, e.g., diatomaceous earth, soil, glass, sand, etc., or material derived therefrom Silicic material 1 mil or less | |
