摘要:
Disclosed is a volume phase hologram recording material of high sensitivity, high contrast, and excellent record retention properties and also disclosed is a volume phase hologram recording medium using the said material. The volume phase hologram recording material mainly contains a three-dimensional crosslinked polymer matrix, a radically polymerizable monomer, and a photoradical polymerization initiator. The three-dimensional crosslinked polymer matrix is formed from a matrix-forming compound having two photoradically polymerizable unsaturated groups and two non-photoradically polymerizable hydroxyl groups represented by the following general formula (1) and another matrix-forming compound having no photoradically polymerizable group.
