SECURITY DEVICE
A security device includes a plurality of diffractive surface elements arranged on a carrier element. A surface covered by the diffractive surface elements on the carrier element can occupy at least a partial region of the carrier element. Each individual diffractive surface element can have a three-dimensional surface structure. A portion of the plurality of the diffractive surface elements can form a first surface element group including the portion of the plurality of diffractive surface elements, and an orientation of the diffractive surface elements in the first surface element group can be matched to each other wherein together they make a single first image point of an associated first symbol to be represented visible to an observer under particular observation conditions.
Display having light-scattering property
A display includes light-scattering regions. Each of the light-scattering regions is provided with linear protrusions and/or recesses having the same longitudinal direction. The light-scattering regions are different from each other in the longitudinal direction.

Security element, value document comprising such a security element, and method for producing such a security element
A security element (1) for a security paper, value document or the like, having a carrier (8) which has an areal region (3) which is divided into a multiplicity of pixels (4) which respectively includes at least one optically active facet (5), whereby the majority of the pixels (4) respectively have several of the optically active facets (5) of identical orientation per pixel (4), and the facets (5) are so oriented that the areal region (3) is perceptible to a viewer as an area that protrudes and/or recedes relative to its actual spatial form.

Security paper, value document obtainable therefrom and method for manufacturing said paper and document
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. The second lacquer involves either a physically drying, water-based dispersion lacquer, or a UV-cross-linking lacquer, and has a matt impression.

Data sheet for a security and/or value document
The invention relates to a datasheet (1) for integrating into a preferably book-like security and/or value document. The datasheet (1) is made of at least two stacked layers (2, 3) made of an organic polymer material. A textile (5) is arranged at least in a sub-region between the layers (2, 3) and outside of the layers (2, 3) so as to form a tab (4), and the textile (5) is at least partly coated on one or both sides and/or saturated with an organic binder (6) at least in the region between the layers (2, 3) and is bonded to the two layers (2, 3) by means of the binder (6).
