摘要:
The invention relates to a photopolymer formulation comprising polyurethane matrix polymers, writing monomers, and photoinitiators, wherein the writing monomers comprise compounds of formula (I), where R1, R2, R3 independent of each other are each a halogen atom or an organic radical, wherein at least one of the radicals is an organic radical comprising a radiation hardening group. The invention further relates to the use of the photopolymer formulation for producing holographic media.
