1. A hologram-recording material, comprising:
a photoresponsive molecule,
a reactive molecule having an intrinsic birefringence, and
a photopolymerization initiator that accelerates polymerization and/or crosslinking of the reactive molecule having an intrinsic birefringence,
a content of the photopolymerization initiator being in a range of from 0.001 wt % to less than about 0.1 wt % relative to the hologram-recording material, and being in a range of from 0.1 wt % to 5 wt % relative to the reactive molecule, and
a content of the reactive molecule having an intrinsic birefringence being in a range of about 30 to about 80 wt % relative to the hologram-recording material.
