  • Patent number: 10195889
    Abstract: 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.
