摘要
This invention provides, for example, a highly stable and reliable volume hologram optical recording medium which can suppress an intensity variation, for example, in diffraction efficiency after signal recording and can stably develop a high S/N ratio. The volume hologram optical recording medium includes a recording layer containing at least one compound selected from compounds (A1) having a terpenoid structure, compounds (A2) represented by a formula (I), and cyclic or noncyclic compounds (A3) having at least two double bonds two of these double bonds are located at 1,4-position relatively, wherein R1 and R2 each independently represent an organic group having 1 to 20 carbon atoms, and R1 and R2 may combine to form a cyclic structure.; 展开▼
