Abstract:
The invention relates to a method for producing a holographic film, wherein a photopolymer formulation comprising matrix polymers, writing monomers, photoinitiator system, and optionally auxiliary materials and additives is provided, the photopolymer formulation is applied as a film to the surface of a substrate, and the film is dried, wherein a photopolymer formulation having a plateau module G0 of =0.03 MPa is used. The invention further relates to a holographic medium that can be obtained by means of the method according to the invention.
