PROBLEM TO BE SOLVED: To provide a new optical information recording material capable of improving various characteristics such as sensitivity, response speed, long-term storage stability and repeated durability in holographic optical information recording. As a photoresponsive site, the following formula (1) (In the formula, HC 1 and HC 2 represent a ring structure containing one or more hetero atoms as ring constituent atoms, R 1 and R 2 represent a hydrogen atom or a substituent bonded to the ring structure, and s and t Represents the number of bonds, and X 1 and X 2 are terminal groups or linking groups and are linked to the main chain as a linking group, and the terminal group is a hydrogen atom or a substituent. The photoresponsive heterocyclic azo compound, which is a polymer having the structural unit represented in at least one of the main chain and the side chain, is used. [Selection] Figure 6 |
