Title:
PHOTOSENSITIVE COMPOSITION FOR VOLUME HOLOGRAM MANUFACTURING, METHOD OF MANUFACTURING VOLUME HOLOGRAM, VOLUME HOLOGRAM, AND HOLOGRAPHIC OPTICAL ELEMENT
Document Type and Number:
Japanese Patent JP2019023669
Kind Code:
A
Abstract:
To provide a photosensitive composition for volume hologram manufacturing used to manufacture a volume hologram having superior diffraction efficiency and durability.SOLUTION: The problem to be solved is solved by letting a photosensitive composition for volume hologram manufacturing contains at least: (a) resin which changed in polarity from hydrophobic properties to hydrophilic properties or from hydrophilic properties to hydrophobic properties because of presence of at least one kind among heat, acid and base; (b) a material which generates at least one kind among heat, acid and base with light; and (c) a compound which has the same polarity as the polarities that (a) has before changing in polarity between the hydrophilic properties and hydrophobic properties, and also has a refractive index of 1.55-2.70.SELECTED DRAWING: None
