Abstract
The invention concerns a security document () having a first transparent region () in which a first transparent optical element () is arranged and a second region () in which a second opaque optical element () is arranged. The second opaque optical element () exhibits a first optical effect. The first region () and the second region () are arranged in mutually spaced relationship on a carrier () 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 () 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 () between the first and second optical elements, which is greater than the first spacing (), a third optical effect () which is different from the second optical effect appears.
