Abstract

A transparent inorganic-oxide dispersion which contains inorganic oxide particles whose surface has been modified with a surface modifier having one or more reactive functional groups and, due to this, enables improvements in refractive index and mechanical properties and retention of transparency; and an inorganic-oxide-particle-containing resin composition obtained by combining and uniting this transparent inorganic-oxide dispersion with a resin through a polymerization reaction. Also provided are: a composition for encapsulating luminescent elements; a luminescent element; a process for producing the resin composition containing inorganic oxide particles; a hard coat and an optical functional film which have high transparency and can attain improvements in refractive index and toughness; an optical lens; and an optical part. The transparent inorganic-oxide dispersion is characterized by comprising a dispersion medium and inorganic oxide particles the surface of which has been modified with a surface modifier having one or more reactive functional groups and which have a dispersed-particle diameter of 1 to 20 nm. It is further characterized in that the surface modifier is one or more members selected from the group consisting of silane coupling agents, modified silicones, and surfactants.
