The invention relates to an antenna configuration, comprising at least one electrically insulating carrier substrate and at least one electrically conductive layer applied on at least one side of the carrier substrate, the electrically conductive layer having a first area region and a second area region, and the first area region of the electrically conductive layer having the form of at least one antenna structure. The at least one antenna structure is present in a manner electrically insulated from the second area region of the electrically conductive layer, and the second area region of the electrically conductive layer is subdivided, at least in regions directly adjacent to the at least one antenna structure, into island regions that are at least electrically insulated from one another. The at least one antenna configuration is suitable for use for contactlessly coupled transponders, in particular for RFID Tags or Smart Tags.

The invention concerns an optically variable element and a security product having such an optically variable element, a foil, in particular an embossing foil or a laminating foil having such an optically variable element, and a process for producing such an optically variable element. The optically variable element has a thin film layer succession with at least one spacer layer for producing color shifts by means of interference. In a first region of the thin film layer succession the spacer layer is of a different layer thickness from in a second region of the thin film layer succession. In that case the layer thicknesses of the spacer layer in the first and second regions are so selected that in the first region of the thin film layer succession a first color shift is produced by means of interference and in the second region of the thin film layer succession a second color shift which is different from the first color shift is produced.
摘要:
In a method of three-dimensionally patterning the surface of a printing or embossing cylinder the surface of the cylinder is irradiated with exposure beams in accordance with the desired pattern and then the surface is patterned in accordance with the exposure. To achieve particularly fine structuring of the cylinder surface, the radiation dots serving to expose the surface are produced by means of beams which, before impinging on the surface of the cylinder, to form fine structures, are modified in accordance with the desired pattern by means of a beam-forming element. The pattern of the respective radiation dot which is impinged on to the cylinder surface is moved synchronously with respect to the movement of the cylinder surface in accordance with the rotary movement thereof.

There is described a process for the production of a partially shaped electrically conductive structure on a carrier substrate (16), wherein it is provided that a latent magnetic image of the graphic form of the electrically conductive structure, which latent magnetic image is formed from magnetic image points (11m) and non-magnetic image points, is produced from a digital data set which defines the graphic form of the electrically conductive structure on a magnetisable printing form (11), and that by means of the printing form (11) magnetic particles having an electrically conductive surface, which are attracted by the magnetic image points are arranged by the lateral magnetic image to afford the graphic form of the electrically conductive structure on the carrier substrate (16) and are fixed there. A multi-layer body produced with that process is further described.

The invention relates to a document of value, in particular a credit card, identity card or ticket, and to a transfer film for the production of a document of value. The latter has on one of its surfaces a security element (2), which has a magnetic layer (25) for storing machine-readable information and a reflective, non-magnetizable metal layer (23). The metal layer is arranged above the magnetic layer (25) in relation to the surface of the document of value. The metal layer and the magnetic layer overlap, at least in some regions. The region of the metal layer (23) that overlaps the magnetic layer (25) is subdivided into at least two regions (231) isolated electrically from one another.
