  • Patent number: 8585093
    Abstract: The booklet comprises a number of sheets between a cover, and each sheet has a front side and a rear side. At least one data page is provided that is joined to the cover in a fixed manner. The data page comprises a flexible layer and this flexible layer projects with an area out of a data carrier. On this area, the data page is joined to the cover and to the remaining sheets. The flexible layer is flatly joined to at least one other layer, for example, by welding or bonding and is thus inseparably bound without a mechanical joining part.
    Type: Grant

  • Patent number: 8419069
    Abstract: In order to produce a data carrier, a substrate is printed with a printing ink and personalized by means of a laser. The printing ink is laser-active and is converted at least in regions during the personalization in such a way that, for example, a silver-grade pigment is formed which is readily visible only when the substrate is inclined. In particular, the printing ink has a comparatively small proportion of carbon black that is converted by the laser essentially without disturbing combustion and overall formation.

  • Publication number: 20070279697
    Abstract: The security element has a pattern, and in particular a Moiré pattern which contains a coded pattern or image which is made visible through a filter. The filter is arranged on a layer that is fixedly connected to a substrate, a distance of at least 0.025 mm being present between the pattern and the filter. When the security element is tilted, the pattern or the image moves continuously. The pattern is preferably a band Moiré pattern. The filter is preferably a line filter that is laser-transmissive. The pattern is preferably produced through the filter by means of a laser. The security element according to the invention is distinguished by high security against forgery and can nevertheless be produced in a comparatively cost-effective manner.
