    摘要： The invention relates to a security element (1), a security document (2) with at least one security element (1), a transfer foil (3) with at least one security element (1) as well as a method for producing a security element (1), wherein the security element has at least one layer (11) that is electrically alterable in its optical effect. It is here provided that the at least one layer (11) that is electrically alterable in its optical effect has liquid crystals (12) that can be oriented in an electric field, wherein the at least one layer (11) that is electrically alterable in its optical effect has rod-shaped dye molecules (13), and the orientations of the longitudinal axes (14) of the rod-shaped dye molecules (13) are alterable depending on the orientations of the longitudinal axes (16) of the spatially adjacent liquid crystals (12) that can be oriented in the electric field, and/or wherein the liquid crystals (12) that can be oriented in the electric field are formed in such a way that the liquid crystals (12) that can be oriented in the electric field simultaneously act as dye molecules.

    摘要： An optically variable element has first and second diffraction gratings which are high-frequency and therefore act reflectively into the zero diffraction order. Either a first color is generated by the first diffraction grating at a particular angle of rotation and a particular angle of illumination and simultaneously a second color, different from the first color, is generated by the second diffraction grating or a visible color is generated essentially only by the first diffraction grating at a first angle of rotation and a visible color is generated essentially only by the second diffraction grating at a second angle of rotation.
