Abstract: Disclosed is a holographic recording medium and methods of manufacturing the holographic recording medium. The example of the medium has a recording layer containing a three dimensionally cross-linked polymer matrix including an epoxy resin, a radically polymerizable monomer, and a photo radical polymerization initiator. The radically polymerizable monomer comprises both N-vinylcarbazole (VC) and N-vinylpyrrolidone (VP) or N-vinylcarbazole alone. The weight ratio of N-vinylcarbazole (VC) to the sum of N-vinylcarbazole (VC) and N-vinylpyrrolidone (VP), i.e., (VC/(VC+VP)), is not smaller than 0.75 and not larger than 1.0.
