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 opticalelement (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, insuch a way that the first and second regions can be brought into mutually overlappingrelationship. Upon overlap of the second optical element with the first optical elementwith a first spacing (26) between the first and second optical elements a second opticaleffect appears and upon overlap of the second optical element with the first opticalelement with a second spacing (25) between the first and second optical elements, whichis greater than the first spacing (26), a third optical effect (51) which is different from thesecond optical effect appears.
