Abstract
The present invention relates to a security element for security papers, value documents and the like, having a microoptical moiré magnification arrangement () for depicting a three-dimensional moiré image () that includes, in at least two moiré image planes spaced apart in a direction normal to the moiré magnification arrangement, image components (), having a motif image that includes two or more periodic or at least locally periodic lattice cell arrangements having different lattice periods and/or different lattice orientations that are each allocated to one moiré image plane and that include micromotif image components for depicting the image component () of the allocated moiré image plane, for the moiré-magnified viewing of the motif image, a focusing element grid that is arranged spaced apart from the motif image and that includes a periodic or at least locally periodic arrangement of a plurality of lattice cells having one microfocusing element each, wherein, for almost all tilt directions ({right arrow over (k)}), upon tilting the security element, the magnified, three-dimensional moiré image () moves in a moiré movement direction ({right arrow over (v)}) that differs from the tilt direction.
