摘要:A security element, particularly for banknotes, security cards and the like,comprising a first substrate which is at least partially opaque when viewed in transmittedlight, and a plurality of magnetic areas being arranged on the substrate, wherein each ofthe magnetic areas is formed by a first magnetic material, a second magnetic material oran arrangement of the first and the second magnetic materials being at least partiallysuperimposed, the first magnetic material and the second magnetic material exhibitingdifferent coercivity values which are detectable by a sensor, wherein the first and secondmagnetic materials are magnetically saturated such that one of the first and secondmagnetic materials is not affected by the other.
