<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a volume type hologram laminate that can obtain high diffraction efficiency.SOLUTION: A method for manufacturing a volume type hologram laminate comprises: a heat treatment step of applying heat treatment to a volume type hologram layer made of a volume type hologram photosensitive composition containing acrylic polymer, acrylic monomer M, a photopolymerization initiator, and photosensitizing dye; and a drawing step of performing drawing with laser light LA on the volume type hologram layer after the heat treatment. The heat treatment is applied before laser light is exposed to the volume type hologram layer containing acrylic polymer. This leads to high diffraction efficiency that is obtained even if laser light is exposed with low power.</p> |
