Abstract
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.
