Title:
PHOTOPOLYMER COMPOSITION, HOLOGRAM RECORDING MEDIUM, METHOD FOR PREPARING SAME, AND OPTICAL ELEMENT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/096360
Kind Code:
A1
Abstract:
The present invention relates to a photopolymer composition, a hologram recording medium, a method for preparing same, and an optical element comprising same. The photopolymer composition contains an electron donor having reaction energy of -25 kJ/mol to 0 kJ/mol with a photosensitive dye excited in a triplet state, and thus, the present invention can provide a hologram recording medium that not only has excellent optical recording properties, such as diffraction efficiency, which are the basic properties of a hologram recording medium, but also, exhibits excellent stability over time at high temperatures before recording optical information, can express the originally intended optical recording properties even when stored for a long time at room temperature or high temperature, and is capable of reproducing clear images without problems, such as halos.
