Abstract

The invention relates to a photopolymer formulation comprising matrix polymers, writing monomers, and photo initiators, comprising a combination of at least two different writing monomers. The invention further relates to the use of the photopolymer formulation for producing optical elements, in particular for producing holographic elements and images, to a method for producing the photopolymer formulation and to a method for illuminating holographic media made of the photopolymer formulation.
