SECURITY ELEMENT, VALUABLE DOCUMENT COMPRISING SUCH A SECURITY ELEMENT AND METHOD FOR PRODUCING SUCH A SECURITY ELEMENT

摘要

The invention relates to a security element (1) for a security paper, document of value or the like, witha support (9) having a reflective surface area (3) divided into a plurality of reflective pixels (5),wherein the area of each pixel (5) is at least an order of magnitude smaller than the area of the reflective surface area (3),wherein each pixel (5) has at least one reflective facet formed in a surface of the carrier,wherein the at least one reflective facet reflects light incident on the surface area (3) along a predetermined direction, directed in a direction of reflection predetermined by its orientation,wherein the reflective surface area on the carrier is divided into at least two partial areas,wherein in a first sub-area the orientations of the facets of different pixels (5) over the reflective area have a substantially random variation and in at least one other sub-area the orientations of the facets of different pixels over the reflective area are such that incident light is in each case narrow Angle range is reflected.
