Title:
PROCESS FOR PRODUCING POROUS SILICA PARTICLES, RESIN COMPOSITION FOR ANTIREFLECTION COATINGS, ARTICLE WITH ANTIREFLECTION COATING, AND ANTIREFLECTION FILM
Document Type and Number:
WIPO Patent Application WO/2012/099185
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a process for producing porous silica particles which enables reduction in the particle diameter and which attains, in the production, a high yield relative to the volume of a reaction solution. A process for producing porous silica particles which have pores on the surface is provided in order to achieve the purpose. This process is characterized by including: a step of adding a mixed fluid (A) which comprises a tetraalkoxysilane, an alkylamine and an alcohol to a mixed fluid (B) which comprises ammonia, an alcohol and water to conduct the hydrolysis and condensation of the tetraalkoxysilane and thus obtain silica particles; and a step of removing the alkylamine from the silica particles.
