摘要:
A data carrier (1) comprises at least one carrier body (2), at least one printing layer (3), at least one marking layer (4), and at least one security element (5). The carrier body (2) can comprise a top surface (6) and the printing layer (3) can be arranged on the top surface (6). The printing layer (3) and the marking layer (4) are arranged at least partially above one another with respect to an extension direction (E). The marking layer (4) is configured to interact with impinging electromagnetic radiation (R) such, that a marking element (8) is generated in the marking layer (4) upon the irradiation of electromagnetic radiation (R). The security element (5) comprises at least part of the printing layer (3) and at least part of the marking layer (4). The printing layer (3) comprises at least one reactive element (9) that is configured to interact with impinging electromagnetic radiation (R) such, that a reacted element (10) is generated in the printing layer (3) upon the irradiation of electromagnetic radiation (R). The marking element (8) can be an opaque element. The security element (5) furthermore comprises the reacted element (10) and the marking element (8).
