Abstract
An optically variable security arrangement for securing valuable articles, comprises a first sub-element having a two-dimensional relief grid composed of a plurality of grid elements and that has, in at least one spatial direction R, a first line screen p below 500 μm, and in which the grid elements are each formed from at least two relief elements that are directionally reflective in different directions, and a second sub-element having at least one dot and/or line grid that, in a spatial direction R, has a second line screen q. A movement effect is created by the interplay of the relief grid and the dot and/or line grid when the security arrangement is tilted.
