Security Document
摘要:
The invention concerns a security document (7) having a first transparent region (72) in which a first transparent optical element (74) is arranged and a second region (71) in which a second opaque optical element (73) is arranged. The second opaque optical element (73) exhibits a first optical effect. The first region (72) and the second region (71) are arranged in mutually spaced relationship on a carrier (75) of the security document, in such a way that the first and second regions can be brought into mutually overlapping relationship. Upon overlap of the second optical element with the first optical element with a first spacing (26) between the first and second optical elements a second optical effect appears and upon overlap of the second optical element with the first optical element with a second spacing (25) between the first and second optical elements, which is greater than the first spacing (26), a third optical effect (51) which is different from the second optical effect appears.
