Abstract: Proposed is a security element, preferably in the form of a security stripe, security thread, or a security patch, comprising a machine-readable code and an optically variable security feature, which has a visual appearance that depends on the viewing angle. The machine-readable code is a magnetic encoding, which is produced by printing at least one opaque magnetic printing ink containing magnetic pigments, with the magnetic printing ink being incorporated or applied in at least one defined code region such that the visual appearance of the optically variable security feature is determined at least in part by the at least one incorporated or applied magnetic printing ink. The optically variable security feature comprises a micro-optical micro-lens arrangement, which covers the at least one code region in which the at least one magnetic printing ink has been incorporated or applied.

Abstract: A method for manufacturing a value document includes: providing a value document substrate; printing the value document substrate with magnetically orientable effect pigments which are dispersed in a UV-curable lacquer; the step of exposing the lacquer containing the magnetically orientable effect pigments to a dynamic magnetic field; the step of irradiating the lacquer containing the effect pigments with UV radiation; and optionally the step of embossing the cured or at least partially cured UV lacquer.

Abstract: A value and safety document comprises a substrate having a front side and a back side. An ink layer is applied to the front or back sides of the substrate. A first motif is incorporated into the ink layer, and is combined with a second motif. The second motif is arranged on the same side of the substrate as the first motif. The second motif is configured in the form of an emboss structure comprising a plurality of raised emboss elements having areas of different orientation. The emboss structure forms the second motif having a second tilt or motion effect, by different groups of emboss elements, having different characteristic parameters, reflecting incident light in different spatial areas. The emboss elements have respectively a lateral dimension of less than 30 μm and a height of less than 10 μm. The first motif is adapted at least partially to the second motif.

CPC classification number: B42D25/382

Abstract: The invention relates to a security element having an optically variable security feature and a machine-readable security feature, which are at least partially arranged one above the other, wherein the security element is transparent or translucent in the region of the visible light and the machine-readable security feature forms a code. The machine-readable security feature is a combination of at least two different substances, a first IR substance and a second IR substance, wherein the first IR substance is arranged in a first areal region of the security element and the second IR substance is arranged in a second areal region of the security element, and wherein the first IR substance absorbs in a first IR wavelength region and the second IR substance absorbs in a second IR wavelength region. The invention also relates to a value document which has such a security element.
