【Task】 Provided are a photosensitive composition for volume phase hologram recording, a hologram recording medium, a production method thereof, and a hologram recording method. [Solution] Consisting of radical polymerization system (A), cationic polymerization system (B), and binder polymer (C), it is used to record the intensity distribution of light and darkness of interference fringes obtained by making light interfere as a change in refractive index. In the composition for volume phase hologram recording material, Photosensitive for volume phase hologram recording, wherein the cationic polymerization initiator (b2), which is a constituent of the cationic polymerization system (B), is a thermal latent cationic polymerization initiator composed of an aluminum complex and an arylsilanol. Composition. [Selection] None. |
