DISPERSOID HAVING METAL-OXYGEN BOND, METAL OXIDE FILM, AND MONOMOLECULAR FILM

摘要

A dispersoid having metal-oxygen bonds which is suitable for use in the production of a thin metal oxide film at a temperature as low as 200°C or below and the production of a homogenous organic/inorganic composite; and a thin metal oxide film and an organic/inorganic composite each having various functions, especially an organic/inorganic composite having a high refractive index and high transparency. The dispersoid having metal-oxygen bonds is characterized by being obtained by mixing a metal compound having three or more hydrolyzable groups with 0.5 to less than 2 mol of water per mol the metal compound in an organic solvent in the absence of an acid, a base, and/or a dispersion stabilizer at a temperature not higher than the hydrolysis initiation temperature and heating the mixture to a temperature not lower than the hydrolysis initiation temperature.
