HOLOGRAPHIC RECORDING MEDIUM, HOLOGRAPHIC RECORDING METHOD, AND HOLOGRAPHIC INFORMATION MEDIUM

摘要

A holographic recording medium wherein a holographic recording layer is interposed between a first base and a second base is characterized in that the holographic recording layer contains at least a binder-forming compound, a compound having an ethylenically unsaturated bond, and a photopolymerization initiator which is capable of initiating polymerization reaction of the compound having an ethylenically unsaturated bond, in that the content of the compound having an ethylenically unsaturated bond is within 1-50 mass% relative to the total amount of the composition, and in that the photopolymerization initiator contains a compound represented by the following general formula (1). [A-Fe-B]<+>.X<-> (1) By having such a structure, the holographic recording medium can be highly sensitive and excellent in storage stability. Also disclosed are a holographic recording method and a holographically recorded holographic information media.
