Title:
体積位相型ホログラム記録用感光性樹脂組成物及びそれを用いた光情報記録媒体
Document Type and Number:
Japanese Patent JP4976373
Kind Code:
B2
Abstract:
Disclosed is a volume phase hologram recording material characterized by excellent photosensitivity, low cure shrinkage, high transparency, and particularly good storage stability and also disclosed is a recording medium prepared therefrom. Further disclosed is a photosensitive resin composition for volume phase hologram recording that comprises a soluble aromatic copolymer (A), a photoradically polymerizable compound (B) capable of copolymerizing with the soluble aromatic copolymer (A), a photopolymerization initiator (C), and a polymer binder (D). The soluble aromatic copolymer (A) has a structural unit of a divinyl aromatic compound and a structural unit of a monovinyl aromatic compound, comprises 10 to 90 mol % of a structural unit represented by the following formula (a1), has a hydroxyl equivalent of 100 to 30,000 g/equiv, a number average molecular weight (Mn) of 400 to 30,000, and a molecular weight distribution (Mw/Mn) of 10 or less, and accounts for 5 to 60 wt % of the composition.
