Abstract

The invention relates to a security element (110), comprising a substrate layer and a security structure (115) formed on the substrate layer, which is constructed having a structural color (210) comprising microcapsules (10) containing colloidal particles (13), which by means of a structural excitation comprising the creation of an electrical and/or magnetic field can be arranged and/or re-arranged in a crystal-like structure to each other. The crystal-like structure (15) has reflection and/or transmission properties for light that can be influenced and/or adjusted by way of the structural excitation. In a non-excited state, the microcapsules (10) have an increased transmission capability and reduced reflection ability for at least one wavelength in the non-visible wavelength region. In the structural excited state, in which an electrical and/or magnetic field generated by way of structural excitation exists in the region of the microcapsules (10), the microcapsules (10) have a reduced transmission capability and an increased reflection ability compared to the non-structural excited state. The invention further relates to a verification method.
