SECURE ELEMENT HAVING A CARD-TYPE BODY MADE OF A PLURALITY OF LAYERS, AND METHOD FOR THE PRODUCTION THEREOF

Abstract: a secure element has a card-type body made of a plurality of layers, arranged one above the other and generated by coextrusion. the secure element includes a first layer as the base layer made of a first material having a base polymer, wherein a first color is homogenously distributed in the first layer as the main color of the body. the secure element includes at least one second layer, as the colored layer made of a second material that has a carrier polymer. the base polymer and the carrier polymer have different material properties with randomized polychromatism visible in plan view and in cross section. the at least one second layer forms, together with the first layer in the card body in a random distribution, colored surface regions, which are dominated in part by the color of the first layer and in part by the color of the second layer.
