ABSTRACT:
The present invention provides a hologram recording material which is suitable for volume hologram record and can attain high refractive index change, flexibility, high sensitivity, low scattering, environment resistance, that is, storage stability, durability, low dimensional change (low shrinkage) and high multiplicity in holographic memory record using not only a green laser but also a blue laser. A hologram recording material comprising: a metal oxide matrix; and a photopolymerizable compound which has at least one (meth)acrylamide group as a photo-reactive group, and has a polyalkylene glycol unit represented by the following formula:in-line-formulae description="In-line Formulae" end="lead"?—(RO)n—in-line-formulae description="In-line Formulae" end="tail"?wherein R represents a lower alkylene group, and n represents the number of repeating units of alkylene oxide.
