Abstract:
1. A security element for a security paper, the security element comprising a carrier having a reflective areal region which is divided into a multiplicity of reflective pixels, the area of each pixel being smaller than the area of the reflective areal region by at least one order of magnitude, each pixel comprising at least one reflective facet which is formed in a surface of the carrier, the at least one reflective facet reflecting light incident along a predetermined direction on the areal region directionally in a reflection direction predefined by the orientation of said facet, and the orientations of the facets of different pixels having a random variation over the reflective areal region, wherein the orientations of the facets of different pixels have a random variation around different average orientations predefined in a region-based manner, resulting in regionally different average reflection directions of the pixels.
