Patent ID: 7767361

Claim:
A hologram recording material comprising: a metal oxide matrix; and a photopolymerizable compound having an aromatic ring, wherein the metal oxide matrix is formed by hydrolysis and polymerization reaction of a metal alkoxide compound, and said metal alkoxide compound includes a metal alkoxide compound having a halogen-containing organic group represented by the following general formula (1): (R H ) m M(OR) n (1) wherein R H represents a halogenated C 1-4 alkyl group, R represents an alkyl group, M represents a metal atom selected from the group consisting of Si, Al, Ti, Zr, Zn, In and Sn, m represents 1 or 2, and m+n represents the valence of the metal atom M; and a metal alkoxide compound having no halogen-containing organic group represented by the following general formula (2): M(OR 2 ) n (2) wherein R 2 represents an alkyl group, M represents a metal atom selected from the group consisting of Si, Al, Ti, Zr, Zn, In and Sn, and n represents the valence of the metal atom M.
