    • A hologram recording material and a hologram recording method, capable of attaining a high sensitivity, a high diffraction efficiency, a satisfactory storability and a dry processability at the same time and applicable to a high-density optical recording medium, a three-dimensional display, a holographic optical element and the like, are provided. The hologram recording method is characterized in causing a change in an alignment of a compound having a specific birefringence upon holographic exposure and fixing the alignment by a chemical reaction so as to record an unrewritable modulation in refractive index in a unrewritable mode. The hologram recording material is characterized in including a low-molecular liquid crystalline compound having a polymerizable group, a photoreactive compound, and a polymerization initiator, and being of an unrewritable type.
