ABSTRACT:
The present invention provides a holographic recording composition and a holographic recording medium comprising a recording layer formed with the holographic recording composition. The holographic recording composition comprises a bifunctional or greater isocyanate, a polyfunctional alcohol comprising a bifunctional alcohol and a trifunctional or greater alcohol, a titanocene-based radical polymerization initiator, a bifunctional or greater acrylate monomer, and an amidine salt denoted by General Formula (1).In General Formula (1), R1, R2, and R3each independently denote an alkyl group, aryl group, amino group, or acyl group, R1and R2may be bonded together to form a ring, R2and R3may be bonded together to form a ring, and A−denotes an anion.
