Abstract: A data carrier (1) comprises at least one substrate layer (2, 2a,...) and at least one processing layer (3). The substrate layer (2, 2a,...) and the processing layer (3) are arranged at least partially above one another with respect to an extension direction (E). The substrate layer (2, 2a...) is at least regionally transparent. The processing layer (3) comprises pigments (4) that are configured to change an appearance, in particular a translucency and/or an opacity and/or a glossiness and/or a colour, upon an irradiation of electromagnetic radiation.

Abstract: Die Erfindung betrifft eine Zusammensetzung, umfassend farbkippende Effektpigmente und ein als Einbettungsmatrix dienendes absorbierendes Bindemittel, das so beschaffen ist, dass die Farbreflexion der im absorbierenden Bindemittel eingebetteten Effektpigmente im sichtbaren Reflexionsspektrum insgesamt verglichen mit der Farbreflexion des reinen farbkippenden Effektpigments in zumindest einer Bande verringert wird, um auf diese Weise einen Farbanteil herauszufiltern, und des Weiteren ein farbkippendes Effektpigment, das von einem absorbierenden Bindemittel umhüllt ist, um auf diese Weise ein Kern-Hülle-Teilchen zu bilden, wobei das absorbierende Bindemittel so beschaffen ist, dass die Farbreflexion des Kern-Hülle-Teilchens im sichtbaren Reflexionsspektrum verglichen mit der Farbreflexion des reinen farbkippenden Effektpigments in zumindest einer Bande verringert wird, um auf diese Weise einen Farbanteil herauszufiltern.

Abstract: A security document is disclosed, comprising first and second security devices, a document substrate, and a protective layer formed of a cured, at least semi- transparent material on a first surface of the document substrate. The surface of the protective layer distal to the document substrate has an integral surface relief structure. The first security device is defined by the surface relief in a first region of the surface relief structure, the second security device is provided at the first surface of the document substrate, and the protective layer covers the second security device.

Abstract: A security device is provided, comprising one or more surface relief structure(s), each formed of one or more cured material(s), the surface relief structure(s) being disposed on a substantially flat substrate and defining a plurality of raised elements spaced from one another, the raised elements corresponding to elements of an image, whereby the plurality of raised elements varies across the surface relief structure(s) so as to exhibit a multi-tonal version of the image. Methods of manufacturing such devices are also disclosed.

Abstract: A security device is disclosed, comprising: a surface relief structure formed of a cured material, the cured material comprising a binder and dispersed therein at least a first pigment having a first detection characteristic. The surface relief structure is configured such that part(s) thereof have dimensions sufficient to accommodate a first concentration of the first pigment and other part(s) have dimensions too small to accommodate the first concentration of the first pigment, and preferably too small to accommodate substantially any of the first pigment. The detection characteristics of the cured material vary across the surface relief structure in accordance with the dimensions thereof.

Abstract: A security device is disclosed, comprising: a substrate having opposing first and second surfaces; on the first surface of the substrate, a surface relief structure formed of one or more cured, at least semi-transparent material(s); and on the second surface of the substrate, a print layer. In at least a first region of the security device in at least part of which the substrate is transparent or translucent, the surface relief structure and the print layer are each defined in accordance with a common image and are in alignment with one another, the surface relief structure exhibiting a first set of feature(s) of the common image and the print layer exhibiting a second set of feature(s) of the common image. The common image is exhibited by the surface relief structure and the print layer in combination with one another and the surface relief structure provides tactility to the common image.
