Abstract:
1. A process for preparing a dispersed ingredient having metal-oxygen bonds that is stably dispersed in an organic solvent without aggregating, the dispersed ingredient having a transmittance of 80-100%, the transmittance being measured under conditions in which a concentration of the dispersed ingredient is 0.5% by weight in terms of oxide, an optical path length of a quartz cell is 1 cm, a control sample is the organic solvent, and a light wavelength is 550 nm, the process comprising: hydrolyzing a metal alkoxide with water in the organic solvent without the addition of acids, bases and dispersion stabilizers; wherein the metal alkoxide is hydrolyzed with 1.0 to less than 2.0 mol of water per mol of the metal alkoxide at a temperature from −50° C. to −100° C.
