Abstract (en)
The document (1) has a carrier layer (2) and a functional layer, where bacteriorhodopsin i.e. biological color pigment, is contained in the functional layer as a color pigment (5) such that the functional layer is constructed as a lower thermo-functional layer (3) and an upper thermo-functional layer (4). The carrier layer is arranged so as to face away from the thermo-functinal layers, where the color pigment is arranged in the upper thermo-functional layer or arranged in the lower thermo-functional layer such that the thermo-functional layers are arranged one above the other. An independent claim is also included for a method for manufacturing a document.
