Abstract:
1. A photopolymer formulation comprising matrix polymers, writing monomers, photoinitiators, and urethanes as plasticizers, where the urethanes as plasticizers are substituted by at least one fluorine atom, the matrix polymers being polyurethanes obtainable by reacting an isocyanate component a) with an isocyanate-reactive component b) having an average of at least 1.5 isocyanate-reactive groups per molecule, characterized in that the writing monomers comprise aromatic compounds of the formula (I) in which at least one of the R 1 , R 2 , R 3 , R 4 , R 5 , R 6 radicals is a radical which is bonded to the aromatic ring at the point X of the formula (II) where X in the formula (II) is a point of attachment, where A in the formula (II) is a linear or branched hydrocarbyl chain optionally containing oxygen or nitrogen, the other R 1 , R 2 , R 3 , R 4 , R 5 , R 6 radicals are each independently hydrogen or an organic radical and R 7 is hydrogen or methyl.
