Abstract
The present disclosure is to provide a photopolymer composition including a polymer matrix or a precursor thereof including a reaction product of a reactive isocyanate compound having a hydrogen bonding functional group capable of forming multiple hydrogen bonds and at least one isocyanate group, and a polyol having at least two hydroxyl groups; a photoreactive monomer; and a photoinitiator, a hologram recording medium produced from the photopolymer composition, an optical element including the photopolymer composition and a holographic recording method using the photopolymer composition.
Claims15
A photopolymer composition, comprising:
- a polymer matrix or a precursor thereof including a reaction product of a reactive isocyanate compound having a hydrogen bonding functional group capable of forming multiple hydrogen bonds and at least one isocyanate group, and a polyol having at least two hydroxyl groups;
- a photoreactive monomer;
- and
- a photoinitiator,
- wherein the reactive isocyanate compound has a structure in which a heterocyclic compound having a hydrogen bonding functional group capable of forming multiple hydrogen bonds;
- and an alicyclic or aromatic compound having at least one isocyanate group are bonded, and
- wherein the heterocyclic compound having a hydrogen bonding functional group capable of forming multiple hydrogen bonds is at least one selected from the group consisting of 2-ureido-4-pyrimidinone, 2-ureido-4-pyrimidinol, 2-amino-6-methylpyrimidin-4-ol, diacylpyrimidine, 2,6-di(acetylamino)-4-pyridyl, 2,7-diamino-1,8-naphthyridine, thymine, uracil, guanine, adenine-thymine dimer, adenine-uracil dimer, and guanine-cytosine dimer, and
- wherein a molar ratio of the reactive isocyanate compound to the polyol is 2 to 8.
