The subject matter of the invention is a method for producing illuminated, holographic media comprising a photopolymer formulation having the adjustable mechanical modulus GUV. A further subject matter of the invention is an illuminated, holographic medium that can be obtained by means of the method according to the invention.
The invention relates to a method for producing holographic media, wherein a photopolymer formulation comprising matrix polymers, writing monomers, a photoinitiator system, and optionally auxiliary materials and additives as components is provided, the photopolymer formulation is applied as a coating on the surface of a carrier film and the photopolymer formulation is dried on the carrier film at a temperature XXYY DEG C., wherein only those compounds having TGA 95 values >100 DEG C. and at least 30 DEG C. above the temperature T are selected as components for the photopolymer formulation. The invention further relates to a holographic medium that can be obtained by means of the method according to the invention.
