Abstract: A security paper for manufacturing value documents has a planar substrate equipped on one surface with an anti-forgery means based on a carrier foil having an optically variable security feature. The anti-forgery means and a partial substrate area surrounding the anti-forgery means is furnished with a dirt-repellent radiation-curing first lacquer substantially not influencing the perceptibility of the optically variable security feature. The layer thickness of the lacquer lying is in a range of 0.7 to 2 micrometers. The radiation-curing first lacquer is may be a UV-cross-linking lacquer which after cross-linking is high-gloss. The substrate can be furnished on its surface lying outside the anti-forgery means with a dirt-repellent second lacquer and optionally partly overlaps the first lacquer in the region of the partial substrate area surrounding the anti-forgery means.

Abstract: A method or apparatus for examining a security element of a value document involves at least one optical property of the security element influenceable by a magnetic field. The value document is transported through a magnetic field which is inhomogeneous transversely to the transport direction and/or is changed time-dependently. An image of at least one portion of the value document having the security element is captured and image data describing the image are formed. The optical properties of the security element are influenced by the magnetic field, and the image data is checked whether they have a location dependence transverse to the transport direction corresponding to the location dependence of the magnetic field and/or have a location dependence in the transport direction corresponding to the time dependence of the magnetic field.

Abstract: An apparatus and method for verifying value documents involves a substrate having at least one light-transmissive region with a first information item. A separate display comprises a gridded arrangement of pixels and a second information item is displayed through the separate display at least regionally to correlate with the first information item. A further information item not recognizable and/or readable to a viewer without auxiliary means is hidden in the first and/or second information item. The substrate is placed with its first information item over the second information item which is displayed on the separate display, and the hidden information item becomes recognizable and/or readable. The first information item is formed by light-transmissive diffractive structures whose surface is furnished with an at least partly reflective coating formed from elements arranged in a gridded manner.

Abstract: The invention relates to a value document, especially a banknote, having a sequence of layers into which visually and/or mechanically perceptible identifiers in the form of patterns, letters, numbers or images are introduced by the action of laser radiation. According to the present invention, the sequence of layers includes a marking layer (22) composed of an ink mixture (24, 26) exhibiting a laser-radiation-absorbing mixture component (26) and a laser-radiation-transparent mixture component (24), the identifiers being visually and/or mechanically perceptible due to an irreversible change in the optical properties of the ink mixture (24, 26), effected by the action of the laser radiation.
