A photosensitive composition for volume hologram recording used for recording an interference fringe produced by the interference of laser beams or lights having excellent coherence as a fringe having a different refractive index, the composition comprising: (a) a radical polymerizable compound having a 9,9-diarylfluorene skeleton, which is liquid at a normal temperature; (b) a compound having compatibility with the component (a), which is selected from the group consisting of a cationic polymerizable compound, a radical polymerizable compound having no 9,9-diarylfluorene skeleton and a plasticizer; and (c) a radical photopolymerization initiator which is sensitive to laser beam having a specific wavelength or light having a specific wavelength and excellent coherence to polymerize the component (a); wherein an average refractive index of the component (a) is larger than that of the component (b). |
