LOW REFRACTIVE INDEX FILM-FORMING COMPOSITION AND METHOD OF FORMING LOW REFRACTIVE INDEX FILM USING THE SAME

摘要

The composition for forming a low refractive index film and the low refractive index film are obtained by mixing a silicon alkoxide (A) with a silicon alkoxide (B) containing a fluoroalkyl group and then adding water (C), formic acid (D) ) Are mixed to produce a hydrolyzate of the mixture, and the hydrolyzate is further mixed with silica sol (F) in which salt columnar colloidal silica particles are dispersed in a liquid medium.
