Document Type and Number:
WIPO Patent Application WO/2023/190493
Kind Code:
A1
Abstract:
A dispersion liquid comprising: metal oxide particles that are surface-modified by a surface modifying material; and a hydrophobic solvent, wherein the metal oxide particles have a refractive index of 2.01-2.50, the surface modifying material contains a silane compound and a silicone compound, the silane compound contains a methyl group-containing silane compound, and, when the dispersion liquid and a methyl phenyl silicone are mixed such that the ratio between the total mass of the metal oxide particles and the surface modifying material to the mass of the methyl phenyl silicone becomes 3:97 and a 1 mm-thick cured product is obtained therefrom, a value obtained by dividing the scattered amount at a wavelength of 450 nm of the cured product by the scattered amount at a wavelength of 600 nm of the cured product is 1.0 or more.
