This invention provides a volume hologram photosensitive composition, which can realize a hologram having an excellent brightness and, at the same time, having excellent heat resistance and mechanical strength, and a photosensitive medium for volume hologram recording using the volume hologram photosensitive composition. The volume hologram photosensitive composition comprises at least a photopolymerizable monomer, a photopolymerization initiator, a sensitizing dye for sensitizing the initiator, and a binder resin. The binder resin comprises a heat curing resin, and optionally a thermoplastic resin, and the thermoplastic resin is contained in an amount of 0 to 25% by weight based on the total solid content of the photosensitive composition.
