| 摘要 |
The present invention provides a process for producing a titanium-containing metal oxide the coloration of which is decreased; a hologram recording material suitable for holographic memory recording using a blue laser, wherein a titanium-containing metal oxide the coloration of which is decreased is used as a metal oxide matrix; a process for producing the same; and a hologram recording medium. A process for producing a metal oxide comprising at least Ti as a metal element, the process comprising: providing an alkoxide compound of Ti to which a glycol other than any geminal diol and any vicinal diol is coordinated; hydrolyzing the alkoxide compound of Ti to which the glycol is coordinated, thereby yielding a precursor of a metal oxide; and advancing polycondensation reaction of the metal oxide precursor, thereby forming the metal oxide.
