A photopolymer composition for holographic recording, the photopolymer composition comprising a photosensitive dye, a co-initiator, a monomer, a cross-linkable monomer, a binder resin, and a solvent,
- wherein the monomer comprises
- or a combination thereof,
- wherein the photosensitive dye comprises a sulfonium derivative of ceramidonin.
A photosensitive dye comprising a sulfonium derivative of ceramidonin represented by:
- where R1 and R2 are each independently a hydrogen atom, a halogen atom, a C1-C5 alkyl group, a C1-C5 alkoxy group, or a primary or secondary amine group having a C1-C5 alkyl group.
A photopolymer composition comprising a photosensitive dye, a co-initiator, a monomer, a cross-linkable monomer, a binder resin, and a solvent,
- wherein the photosensitive dye comprises a sulfonium derivative of ceramidonin represented by:
- where R1 and R2 are each independently a hydrogen atom, a halogen atom, a C1-C5 alkyl group, a C1-C5 alkoxy group, or a primary or secondary amine group having a C1-C5 alkyl group.
