An object of the present invention is to provide a hologram recording material composition comprising a radical polymerizable compound being solid at an ordinary temperature and having a 9,9-diarylfluorene skeleton, a polymeric binder and a plasticizer, the composition being excellent in transparency and diffraction efficiency, which are characteristics required for a hologram. The hologram recording material composition comprises a thermoplastic resin (A) which is soluble in a solvent, a radical polymerizable compound (B) which is solid at an ordinary temperature and at ordinary pressure and has the 9,9-diarylfluorene skeleton and at least one radical polymerizable unsaturated double bond, a plasticizer (C) and a photopolymerization initiator (D). A weight percentage ratio of the thermoplastic resin (A), the radical polymerizable compound (B) and the plasticizer (C), (A) : (B) : (C) is 10 to 80 : 10 to 80 : 10 to 80. A refractive index of the radical polymerizable compound (B) is larger than a weighted mean of that of the thermoplastic resin (A) and that of the plasticizer (C). |
