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

摘要

A low refractive index film-forming composition and a low refractive index film of the present invention are formed by the following: mixing silicon alkoxide (B) containing a fluoroalkyl group with silicon alkoxide (A); adding water (C), formic acid (D), and an organic solvent (E) to the mixture to produce hydrolysate of the mixture; and mixing silica sol (F) in which ringed colloidal silica particles are dispersed in a liquid medium with the hydrolysate.
