Title:
COMPOSITION FOR HOLOGRAPHIC RECORDING, HOLOGRAPHIC RECORDING MEDIUM, HOLOGRAM, AND OPTICAL DEVICE AND OPTICAL COMPONENT BOTH INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2021/095400
Kind Code:
A1
Abstract:
The present invention provides a composition for holographic recording which renders excellent diffraction characteristics possible, a holographic recording medium, a hologram, and an optical device and an optical component both including the hologram. The present invention can provide a composition for holographic recording comprising at least a radical-polymerizable monomer and a matrix resin and giving holographically recorded films which, when examined by atomic force microscopy (AFM), give cross-sectional images each having a diffraction grating structure that shows material density differences observable by the AFM.
