TRANSPARENT INORGANIC-OXIDE DISPERSION, RESIN COMPOSITION CONTAINING INORGANIC OXIDE PARTICLES, COMPOSITION FOR ENCAPSULATING LUMINESCENT ELEMENT, LUMINESCENT ELEMENT, HARD COAT, OPTICAL FUNCTIONAL FILM, OPTICAL PART, AND PROCESS FOR PRODUCING RESIN COMPOSITION CONTAINING INORGANIC OXIDE PARTICLES

摘要

The present invention provides a transparent inorganic oxide dispersion which makes it possible to improve the refractive index and mechanical characteristics and to maintain transparency by modifying the surface of inorganic oxide particles with a surface modifier having one or more reactive functional groups; and an inorganic oxide particle-containing resin composition in which the transparent inorganic oxide dispersion and a resin are compositely integrated by the polymerization reaction, a composition for sealing a light emitting element, a light emitting element, and a method for producing an inorganic oxide particle-containing resin composition; and a hard coat film which has high transparency and makes it possible to improve a refractive index and tenacity, an optical functional film, an optical lens and an optical component. The transparent inorganic oxide dispersion of the present invention comprises inorganic oxide particles which have a surface modified with a surface modifier having one or more reactive functional groups and have a disperse particle diameter of 1 nm or more and 20 nm or less, and a disperse medium, wherein the surface modifier is one or more kinds selected from the group consisting of a silane coupling agent, a modified silicone, and a surfactant.
