PURPOSE: To provide a hologram photosensitive recording material and a hologram photosensitive recording medium which have excellent properties of the chemical stability, the environment resistivity, the resolution, the diffraction efficiency, the transparence, and the regeneration wavelength reproducibility.
CONSTITUTION: The hologram photosensitive recording material and medium are composed of a thermosetting epoxyoligomer which can be solved through solvent, and cation polymerized, whose epoxy equivalent is 1000 to 6000; an aliphatic monomer which includes at least one or more of ethylene type unsaturated combination being liquid at the normal temperature and the normal pressure, whose boiling point is 100°C or higher at the normal pressure, and being radical polymerized; an optical initiator to generate simultaneously a radical seed, and a Brnstes acid or a Lewis acid which activate the radical polymerization and the cationic polymerization being exposed in a chemical function radiant ray; and a sensitizing coloring matter.
