Abstract

A dispersion that inorganic oxide microparticles may be dispersed at a high concentration in a solvent, a composition for film formation having high transparency, high refractive index and adhesion to a base layer. Inorganic oxide microparticles wherein an amphiphilic organosilicon compound having one or more selected from a polyoxyethylene group, a polyoxypropylene group, or a polyoxybutylene group as a hydrophilic group, and one or more selected from a Calkylene group or a vinylene group as a hydrophobic group bonded to a surface of modified metal oxide colloidal particles (C) having a primary particle diameter of 2 to 100 nm, the modified metal oxide colloidal particles wherein a surface of metal oxide colloidal particles (A) having a primary particle diameter of 2 to 60 nm as a nucleus is coated with a coating material (B) including metal oxide colloidal particles having a primary particle diameter of 1 to 4 nm.
