security element and valuable document with such security element

摘要

The present invention relates to a value document (201, 202) with a security element (100, 101, 102), and a strip-like security element with a polymer layer (2) having at least least one etched diffraction structure (3), with at least one reflection layer (4) which optically cooperates with the diffraction structure (3) to form a reflection hologram (5) as the first visually recognizable safety feature, and with at least one luminescent UV radiation printout (6) forming a second visually recognizable security feature under UV light, wherein the reflection hologram (5) has at least one transparent area (8) for viewing the second security feature. In order to increase the protection of the security element against tampering, the present invention suggests that the luminescent print (6) has a halftone image (60) and that the transparent area (8) is formed by at least one half. opening (7) in the reflection layer (4) and by means of the polymer layer (2) which in this area of the opening (7) at least over the halftone image (60) of the printout (6) is free of diffraction structure (3).
