Title:
PHOTOSENSITIVE COMPOSITION FOR FORMING VOLUME HOLOGRAM RECORDING LAYER
Document Type and Number:
WIPO Patent Application WO/2014/061559
Kind Code:
A1
Abstract:
Provided is a photosensitive composition for forming a volume hologram recording layer, whereby it becomes possible to form a volume hologram recording layer that has excellent moisture resistance and thermal stability, does not undergo cure shrinkage upon the recording of a hologram and has excellent multiplexed recording properties.
The photosensitive composition for forming a volume hologram recording layer according to the present invention comprises a three-dimensionally cross-linked polymer matrix precursor material and components (D) and (E) as mentioned below, wherein the three-dimensionally cross-linked polymer matrix precursor material comprises components (A), (B) and (C) as mentioned below at such a content ratio that the molar ratio of a functional group having an active proton in the component (B) to an alicyclic epoxy group in a compound represented by formula (1) in the component (A) (former/latter) becomes 0.01 to 0.3: (A) a cationically polymerizable compound containing a compound represented by formula (1); (B) a compound having a functional group having an active proton; (C) a thermoacid generator; (D) a radically polymerizable compound; and (E) a radical polymerization initiator.
