A security element of at least one multi-layer composition, which composition is capable of interference and consists of at least one reflecting layer, at least one partially transmitting layer and at least one dielectric layer arranged between the reflecting layer and the partially transmitting layer, wherein - the at least one reflecting layer comprises in a first region of the security element a multitude of gaps and - the at least one partially transmitting layer comprises in a second region of the security element at least one gap in form of an alphanumeric character, a drawing or a pattern, or a multitude of gaps, which result in their entirety in an alphanumeric character, a drawing or a pattern, and - 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 and - the security element, when viewed from the partially transmitting layer, displays a different appearance in top view than in transmission view and - the multitude of gaps (4, 6) in the reflecting layer and the partially transmitting layer may have arbitrary shape and are arranged stochastic or grid like and/or vary locally in their diameter or their distance to each other and - the portion of the total area of the gaps in the partially transmitting layer is 10% to 100% with respect to the total area of the region of the partially transmitting layer of the second region, in which an appearance is visible in top view, characterized in that - the portion of the total area of the multitude of gaps in the reflecting layer is 10% to 40% with respect to the total area of the reflecting layer of the first region. - the at least one reflecting layer comprises in a first region of the security element a multitude of gaps and - the at least one partially transmitting layer comprises in a second region of the security element at least one gap in form of an alphanumeric character, a drawing or a pattern, or a multitude of gaps, which result in their entirety in an alphanumeric character, a drawing or a pattern, and - 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 and - the security element, when viewed from the partially transmitting layer, displays a different appearance in top view than in transmission view and - the multitude of gaps (4, 6) in the reflecting layer and the partially transmitting layer may have arbitrary shape and are arranged stochastic or grid like and/or vary locally in their diameter or their distance to each other and - the portion of the total area of the gaps in the partially transmitting layer is 10% to 100% with respect to the total area of the region of the partially transmitting layer of the second region, in which an appearance is visible in top view, characterized in that - the portion of the total area of the multitude of gaps in the reflecting layer is 10% to 40% with respect to the total area of the reflecting layer of the first region.
