A hologram-recording material, including 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 less
than about 0.1 wt % relative to the hologram-recording material, 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.
