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.

Optically variable security element

The present invention relates to an optically variable security element for securing valuable articles, having a substrate having opposing first and second main surfaces and, arranged on the first main surface, an optically variable pattern that comprises an embossing pattern and a coating. The coating comprises at least one imprinted line grid and a background layer that contrasts with the line grid. The embossing pattern comprises a two-dimensional grid of elevated and/or depressed embossing elements. Both are combined in such a way that substantially on every embossing element lies at least one line segment of a line in the line grid, and at least one of the parameters position of the line segment on the embossing element, orientation of the line segment on the embossing element and form of the line segment varies location dependently across the dimension of the optically variable pattern. Due to the line grid, a movement effect, especially a pump or rotation effect, is created when the security element is tilted.

The invention relates to a security element with an optically variable structure, which has an embossed structure and a coating, wherein the embossed structure and the coating are combined such that at least parts of the coating are completely visible upon perpendicular viewing, but are concealed upon oblique viewing. This embossed structure has nonlinear embossed elements, which are combined with the coating such that when changing the viewing direction different pieces of information become visible.
