Document Type and Number:
WIPO Patent Application WO/2017/170275
Kind Code:
A1
Abstract:
[Problem] To provide: a dispersion of inorganic oxide microparticles dispersed in a high concentration in a solvent; a composition for film formation having high transparency, a high refractive index, high adhesion to an underlayer, and excetional weather resistance; and an optical member. [Solution] Inorganic oxide microparticles in which an amphiphilic organic silicon compound that has one or more selected from a polyoxyethylene group, a polyoxypropylene group, and a polyoxybutylene group as a hydrophilic group and has one or more selected from a C1-18 alkylene group and a vinylene group as a hydrophobic group is bonded to the surface of modified metal oxide colloidal particles (C) having a primary particle size of 2-100 nm, the modified metal oxide colloidal particles (C) having metal oxide colloidal particles (A) that have a primary particle size of 2-60 nm as a core and having the surface of the metal oxide colloidal particles (A) coated by a coating (B) that comprises metal oxide colloidal particles having a primary particle size of 1-4 nm; and a composition for film formation, the composition containing the inorganic oxide microparticles.
