The invention relates to aromatic 4,6-bis-trichloromethyl-s-triazin-2-yl- compounds of formula (I). The invention also relates to a photopolymer formulation containing a photopolymerisable component and at least one aromatic 4,6-bis-trichloromethyl-s-triazin-2-yl- compound of formula (I), and a photopolymer comprising matrix polymers, a writing monomer, a photoinitiator and at least one aromatic 4,6-bis-trichloromethyl-s-triazin-2-yl- compound of formula (I), a holographic medium that contains the corresponding claimed photopolymer, a hologram containing a claimed holographic medium, a method for producing a hologram using pulsed laser radiation, and the use of a claimed holographic medium to record a hologram. |
