Abstract
A metal oxide-based fine particle includes a metal oxide-based core region; an intermediate region formed on the outer periphery of the core region, the intermediate region having an alkoxyorganosiloxane condensate structure; and a surface region including an organic molecular chain or an organic silicon molecular chain or a reactive functional group.

A metal oxide-based fine particle comprising:
- a metal oxide-based core region;
- an intermediate region comprising an alkoxyorganosiloxane condensate structure, the intermediate region being formed on the outer periphery of the core region;
- and
- a surface region comprising an organic molecular chain or an organic silicon molecular chain or a reactive functional group,
- wherein the metal oxide-based fine particle is a fine particle formed by a reaction between organometallic compounds each comprising a first section comprising a metal alkoxide group comprising a plurality of alkoxy groups each having 1 to 3 carbon atoms, a second section comprising an alkoxyorganosiloxane structure portion, the second section being bonded to the first section, and a third section comprising an organic molecular chain or an organic silicon molecular chain or a reactive functional group, the third section being bonded to the second section;
- the metal oxide-based core region is a region formed by condensation between the metal alkoxide groups of the first sections;
- the intermediate region is a region formed by condensation between the alkoxyorganosiloxane structure portions of the second sections;
- and
- the surface region is a region comprising the organic molecular chains or the organic silicon molecular chains or the reactive functional groups of the third sections.
A method for manufacturing a metal oxide-based fine particle comprising a metal oxide-based core region, an intermediate region comprising an alkoxyorganosiloxane condensate structure, the intermediate region being formed on the outer periphery of the core region, and a surface region comprising an organic molecular chain or an organic silicon molecular chain or a reactive functional group, the method comprising:
- forming the metal oxide-based core region by a reaction between organometallic compounds each comprising a first section comprising a metal alkoxide group comprising a plurality of alkoxy groups each having 1 to 3 carbon atoms, a second section comprising an alkoxyorganosiloxane structure portion, the second section being bonded to the first section, and a third section comprising an organic molecular chain or an organic silicon molecular chain or a reactive functional group, the third section being bonded to the second section, to conduct condensation between the metal alkoxide groups of the first sections;
- and
- forming the intermediate region by the reaction to conduct condensation between the alkoxyorganosiloxane structure portions of the second sections, and forming the surface region comprising the organic molecular chains or the organic silicon molecular chains or the reactive functional groups located on the outer periphery of the intermediate region.
