    摘要: A security element comprises a first transparent film, on which a holographic layer is formed having a holographic surface structure, a reflective layer arranged in contact with the holographic layer having a pattern of non - transparent regions and transparent regions, a color changing layer, and a photoactive layer having dark regions and transparent regions. In first regions, parts of the non-transparent regions of the reflective layer are not overlapped by the dark regions of the photoactive layer. In second regions, the color changing layer is backed by the dark regions of the photoactive layer. In third regions, the transparent regions of the photoactive layer are at least partly in register with the transparent regions of the reflective layer so that the third regions are continuous when passing from patterns outside the non-transparent regions of the reflective layer to patterns outside the dark regions of the photoactive layer. With this arrangement, when viewed in reflected light, a holographic effect is visible in the first regions and simultaneously a color change effect is clearly visible in the second regions. Furthermore, when viewed in transmitted light, a transparency effect is visible in the third regions. Accordingly, a multifunction security element is provided, in which security is improved by combining multiple effects in visual inspection.

    摘要: There is provided a security sheet (10) as well as a manufacturing method thereof and a security document comprising or being composed of such security sheet, wherein the security sheet comprises a sheet material (11) and a security element (12) embedded in the sheet material (11). The security element (12) includes a passive RFID tag (13) comprising at least a chip (15) with a memory (17) and an antenna (14). A universal unique identifier for uniquely identifying the security sheet (10) is invariably stored in the memory (17). The universal unique identifier comprises a unique code representing a unique random number generated during manufacturing of the security sheet (10) and stored in a memory area which is protected by a one-time password for a single writing operation during manufacturing of the security sheet.
