Abstract:
1. A hologram recording material comprising: a polymerizable monomer (A) that is active in radical polymerization but is substantially inactive in cationic polymerization; a polymerizable monomer (B) that is active in cationic polymerization but is substantially inactive in radical polymerization; an initiator system (C) that polymerizes at least one of the polymerizable monomer (A) and the polymerizable monomer (B) through irradiation with light; and a plasticizer (D) that is in a liquid state at room temperature, the plasticizer (D) having a refractive index lower than an average refractive index of any of the polymerizable monomer (A) and the polymerizable monomer (B) by 0.03 or more, wherein at least one component of the polymerizable monomer (A) and at least one component of the polymerizable monomer (B) each have, in its structure, a 9,9-diarylfluorene skeleton.
