Abstract (en)
[origin: WO2014076245A1] The present invention relates to a security element for a document of value and/or a security document which is arranged on a transparent layer, for example a film (1, 1'), wherein the security element has a first periodic, optical structure, for example a grid of lines (10, 30, 30') or a grid of points, which forms a first coating on the first side of the transparent layer, and a second periodic, optical structure, for example a grid of lines (20, 40, 40', 40'') or a grid of points, which forms a second coating on the second side, opposite from the first side of the transparent layer. In order to achieve better protection against copying, the first optical structure and the second optical structure are preferably arranged as overlapping in such a way that, when seen by an outside observer from a certain, predetermined viewing angle (α) or lighting angle, they show a colour-changing effect, wherein the first coating has a first colour and the second coating has at least one second colour that is different from the first colour.
