Abstract: 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.

Abstract: A security element for securing valuable articles comprises an optically variable layer (18) that conveys different color impressions at different viewing angles, and a color-constant layer (17, 24).

The color impression of the stacked layers (18, 17, 24) in the covering region (20) and the color impression of the one layer (18) outside (22) the covering region are matched with each other when viewed at a predetermined viewing angle. Further, the color-constant layer comprises an ink layer (17) and a metal layer arranged below the ink layer (24).

Abstract: The present invention relates to a security element composed of at least one light-transmitting substrate on which a substantially opaque, screened layer composed of grid elements is located. According to the present invention, within the substantially opaque, screened layer composed of grid elements, at least one thin, solid, substantially opaque line is arranged that exhibits the form of at least one alphanumeric character, a graphic or a pattern. Such lines have line widths of at least 0.1 mm to 5 mm, preferably of 0.2 mm to 0.7 mm, particularly preferably of about 0.5 mm. Instead of lines, also extensive regions without any gap may be used, such that the alphanumeric character, pattern or graphic formed is perceptible only in transmitted light, but not in reflected light. The security element thus displays, at least when viewed from the side of the substantially opaque, screened layer, in top view, a different appearance than when looked through.
