First claim
Opening claim text (preview).
What is claimed is: 1 . A composition for a hologram recording material, the composition comprising: a binder precursor containing a compound having a structure represented by formula A below; a polymerizable monomer; and a photopolymerization initiator, in the formula A, R 1 to R 3 each represent a hydrogen atom or a substituent, E represents a divalent electron attracting group, a wavy line portion represents a bonding site with another structure, and when E is —C(═O)O—, R 3 is not an alkyl group. 2 . The composition for a hologram recording material according to claim 1 , wherein the binder precursor contains a polyol compound and a polyisocyanate compound, and at least one of the polyol compound and the polyisocyanate compound contains a compound having a structure represented by the formula A. 3 . The composition for a hologram recording material according to claim 2 , wherein the polyol compound contains a compound having at least two hydroxyl groups and at least one (meth)acryloyloxy group. 4 . A hologram recording material produced by polymerizing the binder precursor contained in the composition for a hologram recording material according to claim 1 . 5 . A hologram recording medium produced by polymerizing the polymerizable monomer contained in the hologram recording material according to claim 4 .
