Title:
REWRITABLE HOLOGRAM RECORDING MATERIAL, METHOD FOR RECORDING/ERASING HOLOGRAM, AND HOLOGRAM RECORDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138277
Kind Code:
A1
Abstract:
A rewritable hologram recording material having characteristics in which fast responsiveness and long-term memory are both achieved, wherein the rewritable hologram recording material is characterized by containing: a copolymer obtained by introducing a carbazole azobenzene in a portion of the side chain of an acrylic polymer; and a carbazole azobenzene molecule that is the same type or a different type as the above-noted carbazole azobenzene.
