发明名称 Security element and method for the production thereof
摘要 The present invention relates to a security element for protecting valuable articles, having a first and a second authenticating feature. The first authenticating feature comprises a first arrangement having a plurality of focusing elements present in a first grid, and a second arrangement having a plurality of microscopic structures present in a second grid. Here, the first and second arrangement are disposed in such a way that the microscopic structures of the second arrangement are seen magnified when viewed through the focusing elements of the first arrangement. The second authenticating feature is machine and/or visually verifiable and is not influenced by the first arrangement of the first authenticating feature.

主权项 1. A security element for securing valuable articles, having at least one first authenticating feature, the first authenticating feature comprising a first arrangement, having a plurality of lens-shaped focusing elements that are present in a first grid, and a second arrangement, having a plurality of microscopic structures that are present in a second grid, the first and the second arrangement being disposed in such a way that the spatial frequencies of the two grids differ slightly and, as a result of a moiré effect, the microscopic structures of the second arrangement are seen magnified when viewed through the lens-shaped focusing elements of the first arrangement, and a second authenticating feature that is visually verifiable and is not magnified by the first arrangement of the first authenticating feature, wherein the microscopic structures of the second arrangement of the first authenticating feature comprise embossed microstructures that are coated with a metal reflection layer that provides the second authenticating feature and that exhibits apertures in the form of characters, patterns or codes, and/or is present in the form of characters, patterns or codes, and wherein the magnification effect of the lens-shaped focusing elements of the first arrangement does not relate to the second authenticating feature.
