Abstract:
The present invention relates to a security element (20) for security papers, value documents and the like, having a micro-optical moiré magnification arrangement having a motif image that consists of a periodic or at least locally periodic arrangement of a plurality of micromotif elements (28) that is planar or applied on a curved surface, and a periodic or at least locally periodic arrangement of a plurality of microfocusing elements (24) that is planar or applied on a curved surface, for moiré-magnified viewing of the micromotif elements (28) of the motif image, the arrangement of micromotif elements (28) and/or the arrangement of microfocusing elements (24) exhibiting, in the planar case, no symmetry axis in the plane of the arrangement in its periodic or at least locally periodic regions.
