Abstract: A platelet-shaped magnetic effect pigment is provided for use in a printing ink, and includes a layer construction with a magnetic layer and at least one optical functional layer, such that the magnetic layer is based on a magnetic material having a column-shaped nanostructure and the magnetic columns respectively have a largely uniform preferential magnetic direction deviating from the platelet plane.

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 method for producing pigments having a specified contour, comprises the steps of creating a pigment layer on a starting substrate; detaching from the starting substrate; and structuring the pigment layer into a plurality of the pigments; characterized by bringing into contact the pigment layer with an intermediate substrate, wherein the pigment layer adheres at least in sections to the intermediate substrate; and separating intermediate substrate and starting substrate.

Abstract: A platelet-shaped pigment with a layer construction comprises the following layers in the order, optionally a carrier substrate; a transparent embossing lacquer layer with an embossed relief structure; a reflection-increasing coating which follows the relief structure and forms a reflecting microstructure, wherein the reflecting microstructure is present in the form of a mosaic of a multiplicity of reflecting mosaic elements and the reflecting mosaic elements do not reflect the incident light in the direction of the specular reflex, regarding the plane of the platelet, but in a spatial direction deviating therefrom and respectively have a lateral dimension 1 greater than 2 μm.

Abstract: A method for producing a security element for security papers, valuable documents or the like, includes a carrier having on its top side micro-imaging elements and on its underside structures which, together with the microimaging elements, image a motif in front of the top side of the carrier; the position of the motif being is dependent on the viewing angle.
