PURPOSE:To reform the surface conditions of an inorganic coat film and prevent clouding by reacting a specified silane compound with the inorganic coat film followed by graft polymerization with a material having aftertreatment or unsaturated bonding. CONSTITUTION:A silane compound having either one of a substitutent or unsaturated bonding to be converted into a hydrophilic group by aftertreatment is reacted with an inorganic coat film mainly containing SiO2. A material having aftertreatment or unsaturated bonding is successively graft-polymerized with it. Thus, the physical property of the inorganic coat film is changed, and the characteristic of the coat film is remarkably changed. When hydrophilic property is given to the surface by the aftertreatment, the contact angle of water is reduced, whereby fine water droplet is difficult to generate, and the clouding phenomenon by irregular reflection of light is prevented. Further, the electric conductivity of the surface is increased, whereby the charge on the surface is prevented, and dust is difficult to adhere to the coat film surface. |
