METHOD FOR PRODUCING ANTIREFLECTION REINFORCED GLASS

摘要

Provided is a method for producing antireflection reinforced glass in which an antireflection film is formed, after which the glass is reinforced by chemical reinforcement using ion exchange. A method for producing an antireflective reinforced glass by forming an antireflection film on the surface of a glass substrate and then subjecting the glass substrate on which the antireflection film has been formed to chemical reinforcement using ion exchange, wherein the antireflection film comprises: (a) the hydrolysis condensate of a silicon compound represented by formula (1): Rn-Si(OR1)4-n (1)(where R is an alkyl or alkenyl group, R1 is an alkyl or alkoxyalkenyl group, and n is an integer between 0 and 2); (b) a silica sol, the grains of which comprise a hollow cavity on the inside and have a grain size of 5 to 150 nm; and (c) a metal chelate compound. The weight ratio (a/b) of silicon compound hydrolysis condensate (a) and silica sol (b) is within a range of 50/50 to 90/10, and the amount of metal chelate compound (c) is 20 parts by weight or less with respect to a total of 100 parts by weight of silicon compound hydrolysis condensate (a) and silica sol (b).
