ABSTRACT:
An ultrafine mixed-crystal oxide, wherein the oxide has a change in absorbance of about 5 (/hr) or less when measured in such a manner that said oxide is dispersed at a concentration of 0.067% in a solvent of a 98% glycerin in which Sunset Yellow is dissolved at a concentration of 0.02%, thereby preparing a dispersion, and the dispersion is irradiated with a BLB lamp (ultraviolet light) with an intensity of 1.65 mW/cm2to obtain said change in absorbance (ΔOD) at 490 nm.
