Title:
SURFACE-COATED INORGANIC PARTICLES, METHOD FOR PRODUCING SAME, AND ORGANIC-SOLVENT DISPERSION OF SAME
Document Type and Number:
WIPO Patent Application WO/2021/182378
Kind Code:
A1
Abstract:
Provided are: surface-coated inorganic particles which can have improved dispersibility in organic solvents and enable the function and performance of the original inorganic particles to be sufficiently exhibited; and a method for producing the surface-coated inorganic particles. Also provided are an organic-solvent dispersion and a coating film which are excellent in terms of transparency and refraction property. The surfaces of inorganic particles, e.g., titanium oxide, are coated with a product of reaction between an aminated silicate compound, e.g., aminopropyltrimethoxysilane, and/or a product of the hydrolysis thereof and a compound having one α,β-unsaturated carbonyl group in the molecule, e.g., an alkoxypolyalkylene glycol (meth)acrylate.
