    Abstract: A hologram recording material includes 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, and an initiator system (C) that polymerizes at least one of the polymerizable monomer (A) and the polymerizable monomer (B) through irradiation with light. The polymerizable monomer (A) and the polymerizable monomer (B) each have, in its structure, a moiety selected from the group consisting of aromatic rings, halogen atoms other than a fluorine atom, and sulfur atoms not derived from a cyclic sulfide or a mercapto group. A hologram recording medium includes a recording layer composed of the hologram recording material.

    Abstract: An information recording medium of the present invention is an information recording medium characterized by and including a substrate; and a recording unit capable of recording three-dimensionally a recording pit on the substrate; in which the recording unit has n number of recording layers (n is an integer equal to or larger than 4) and a plurality of intermediate layers laminated with the recording layers one on another; the recording is performed by the condensed recording light using a two photon absorption phenomenon; each of the plurality of intermediate layers is substantially transparent at a wavelength λ1 of the recording light and at a wavelength λ2 of the reproduction light, respectively; the light intensity of the recording light incident into the recording layer nearest to the substrate is more than 0.707 fold as much as the light intensity of the recording light incident into the recording layer farthest from the substrate. The information recording medium is an information recording medium capable of maintaining a precise and good recording accuracy at the recording layer positioned lower away from the objective lens while it secures the focus servo reflected light.

    Abstract: A photosensitive composition (I) for volume hologram recording includes a binder polymer (A), a photo-induced cationically polymerizable compound (B), a photoinitiator (C), and a sensitizing dye (D), in which the binder polymer (A) is a polymer containing naphthalene rings and having a weight-average molecular weight of 1×104 to 100×104. A method produces a photosensitive composition (II) for volume hologram recording by mixing a binder polymer (A′), a photo-induced cationically polymerizable compound (B′), a photoinitiator (C′), and a sensitizing dye (D′), in which the photo-induced cationically polymerizable compound (B′) has been subjected to a heating treatment at a temperature equal to or lower than the boiling point of the compound (B′).
