<P>PROBLEM TO BE SOLVED: To provide a volume hologram recording photosensitive composition having an extremely superior refractive index modulation and high polymerization reactivity, having an extremely small volume shrinkage, and being unlikely to cause sensitivity deterioration in multi-recording. <P>SOLUTION: The volume hologram recording photosensitive composition according to the present invention includes: a binder polymer (A); a cationic photopolymerizable compound (B); a cationic photopolymerization initiator (C); and a titanocene compound (D). The binder polymer (A) is a polymer having a naphthalene ring and a weight average molecular weight of 10,000-1,000,000. <P>COPYRIGHT: (C)2013,JPO&INPIT |
