Abstract:
The present invention relates to a photopolymer formulation containing chemically crosslinked matrix polymers, writing monomers and a photoinitiator system, wherein the photoinitiator system contains a HABI, a dye attuned to the HABI and having an absorption maximum in the range of 400-800 nm and a hydrogen donor. The present invention further relates to a process for producing exposed holographic media with the above photopolymer formulation.
