Hologram recording material and hologram recording medium

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, durability, low dimensional change (low shrinkage) and high multiplicity in holographic memory record using not only a green laser but also a blue laser; and provides a hologram recording medium having a hologram recording layer comprising the hologram recording material. A hologram recording material comprising a metal oxide matrix and a photopolymerizable compound, wherein the metal oxide matrix comprises at least Si and Ti as metallic elements, and Ti originates from titanium-containing oxide fine particles. A hologram recording medium (11) having the hologram recording layer (21) comprising the hologram recording material.
