Abstract
A flat security element has a main plane and microreflector arranged in a microreflector pattern and present at least one motif that, when the security element is tilted, has a motif effect that relates to the main plane. The microreflector pattern causes a first and a second motif effect, wherein the first motif effect occurs during a tilting movement about a primary axis, if the security element is at the same time oriented within a first tilting angle range about a secondary axis, and the second motif effect occurs during the tilting movement about the primary axis, if the security element is at the same time oriented within a second tilting angle range about the secondary axis.
