Abstract
An optically variable security element for securing valuable articles, has a relief grid having a plurality of relief elements arranged in a grid pattern and at least one line grid arranged vertically above or below the relief grid and having a plurality of line elements that run substantially in the same direction and that are location-dependently modulated. The relief grid and the at least one line grid coact to produce for a viewer, through the location-dependent modulation of the line elements, a surface that, with respect to the area of the security element, jumps out and/or back in the form of a specified three-dimensional image motif.
