发明名称 SECURITY ELEMENT COMPRISING AN OPTICALLY VARIABLE ELEMENT
摘要 The invention relates to a security element of at least one thin layer element in form of a multi-layer composition, capable of interference. The multi-layer composition, capable of interference, consists of at least one reflecting layer, at least one partially transmitting layer and at least one dielectric layer arranged between these layers. According to the invention the security element comprises in a first region a multitude of gaps in the reflecting layer and in a second region at least one gap or a multitude of gaps in the partially transmitting layer. Herein the second region is arranged at least partially within the first region and the total area of the second region, which is at least partially arranged within the first region, is smaller than the total area of the first region. Therefore the security element displays, when viewed from the partially transmitting layer, a different appearance in top view than in transmission view.
