Photosensitive for volume hologram recording, capable of obtaining a hologram recording material having high transmittance and light resistance that prevents the hologram from being deteriorated even by a high-power laser without reducing the hologram recording ability. A composition is provided. A cyanine dye, which is a sensitizing dye that has absorption at a hologram recording wavelength and can be excited to pass energy to a photopolymerization initiator, a photopolymerization initiator, a photopolymerizable compound, and a hologram recording wavelength light. A photosensitive composition for volume hologram recording, comprising a sulfonate-based acid generator that is inert to irradiation and generates an acid by heat. [Selection figure] None |
