Volume hologram optical recording medium, composition for forming volume hologram recording layer, volume hologram recording material and volume hologram optical recording method |
abstract |
A volume hologram optical recording medium having a recording layer with low hygroscopicity is provided. In a volume hologram optical recording medium having a multi-layer structure having a transparent substrate and a recording layer, the recording layer contains a resin matrix (A) and / or a resin matrix (B) and a photoactive compound (C), and includes a resin matrix (A). ) Is obtained by reacting a polyisocyanate (A1) with a polyol (A2) having a-(C = O) O- group and / or a -O (C = O) O- group, and the resin matrix (B) is 1 It is obtained by making the epoxy compound (B1) which has two or more epoxy groups, and a hardening | curing agent (B2) react in a molecule | numerator, and the moisture absorption of this recording layer is 1.5 weight% or less. |
