Low reflectance glass

Abstract

Abstract PURPOSE:To obtain a low reflectance glass having superior adhesion, hardness of coated film, and scratch resistance by bonding the surface of glass or precoated film to a coted film for processing to low reflectance interposing a thin film of a specified org. polyhydroxy compd. CONSTITUTION:Glass surface washed with a detergent and dil. hydrofluoric acid, then dried after washing with water is coated, if necessary with a precoating agent [e.g. Ti(OCH3)4], and cured at 200-550 deg.C to form a precoating film having 0.1-10mu thickness. Further, an org. polyhydroxy compd. (e.g. polyethylene glycol) contg. >=2 OH gps is coated on the glass plate or on the precoated film to form a thin film having <=0.01mu thickness. Then, a processing agent for providing low reflectance comprising a condensation product of fluorine-contg. silicone compd. is coated thereon, cured at 120-250 deg.C to form a coated film having 1-0.05mu thickness.
