Estimating the term…
The invention relates to a security material comprising a carrier and at least one photochromic Protein and/or a mutein of a photochromic protein. The security material is characterised in that it comprises at least one irreversible photosensitive layer on the carrier, and the at least one photochromic protein and/or mutein is contained at least in the at least one photosensitive layer and/or in an optional additional layer. The inventive security material is also characterised in that it is highly forgery-proof, the photochromic biomolecule cannot be removed therefrom in a usable form, and the photochromic biomolecule does not need to be supplied to a large group of clients.
A security material having a carrier and at least one photochromic protein and/or a mutein of a photochromic protein, wherein the security material has at least one irreversibly photosensitive layer on the carrier and wherein the at least one photochromic protein and/or mutein are contained in the at least photosensitive layer and/or in an optional additional layer.
A method for manufacturing a material having a carrier and at least one photochromic protein and/or mutein of a photochromic protein, which is contained in a layer, and wherein the material may be comprised of further layers, wherein the layer and layers, respectively, are manufactured in a continuous casting operation.
A material, having directly on a carrier a layer, which comprises a binder and/or a thickening agent and above a layer, which contains a photochromic biomolecule.
