According to the present invention, it is provided that the two absorber layers (34, 38) are each formed from a material having a complex refractive index N whose real part n and imaginary part k differ at least in a portion of the visible spectral range by a factor of 5 or more.
The invention relates to a security element comprising at least one light- permeable substrate (2) on which a substantially opaque, rastered layer (1) of raster elements (3) is placed. According to the invention, at least one thin, continuous, substantially opaque line (4) that has the shape of at least one alphanumeric character, a graphic element, or a pattern is arranged within the substantially opaque, rastered layer of raster elements. Such lines have a minimum width of 0.1 to 5 mm, preferably 0.2 to 0.7 mm, even more preferably about 0.5 mm. Planar zones without recesses can also be used instead of lines such that the formed alphanumeric character, pattern, or graphic element is visible only in rear illumination but not in front illumination. The image displayed by the security element in front illumination is thus different from the image displayed in rear illumination, at least when viewed from the side of the substantially opaque, rastered layer.

The invention relates to a security element of at least one thin layer element in form of a multi-layer composition, capable of interference. The multi-layer composition, capable of interference, consists of at least one reflecting layer, at least one partially transmitting layer and at least one dielectric layer arranged between these layers. According to the invention the security element comprises in a first region a multitude of gaps in the reflecting layer and in a second region at least one gap or a multitude of gaps in the partially transmitting layer. Herein the second region is arranged at least partially within the first region and the total area of the second region, which is at least partially arranged within the first region, is smaller than the total area of the first region. Therefore the security element displays, when viewed from the partially transmitting layer, a different appearance in top view than in transmission view.
The invention relates to a security element having an optically variable structure which has an embossed structure. Upon tilting the security element around an axis and thus alternating viewing from a first and second viewing angle range a tilt effect is produced which from the two different angles of view or under different angles of light incidence shows different colors or brightnesses. According to the invention, the optically variable structure has at least one second embossed structure which is disposed within the first embossed structure and in addition to the first tilt effect produces a second tilt effect. The second tilt effect here either occurs within the first or second viewing angle range or upon the transition from the first to the second or from the second to the first viewing angle range.
An apparatus for handling documents of value comprises at least a first device, which has a transport path portion, along which a document of value is transported to and/or from the first device and/or into the first device, at least a second device, which has a transport path portion, along which a document of value is transported to and/or from the second device and/or into the second device, wherein the devices are arranged such that a document of value can be transported from the transport path portion of the first device into the one of the second device and/or from the transport path portion of the second device into the one of the first device, and at one coupling end of the respective transport path portion in a fixed position in relation to the respective transport path portion a pair of rolls mounted to be rotatable around a rotation axis, between the rolls of which a document of value is clamped when transported and the rolls of which in a section through the rotation axis have a comblike structure, the pairs of rolls being arranged and formed such that the rolls of a first of the pairs of rolls and the respective rolls of a second of the pairs of rolls in the coupling position intermesh in a combing fashion.

APPARATUS AND METHOD FOR OPTICAL ANALYSIS OF VALUE DOCUMENTS
An apparatus for optical analysis of at least one value document (12) in a recording area (38) of the apparatus has an illumination device (36) for illuminating the value document (12) in the recording area (38) and possessing at least one surface emitting laser diode (50), a control device (42) for driving the laser diode (50), and a detection device (40) for recording optical radiation from the recording area (38).
The invention relates to a security element for security papers, documents of value and the like, having a front side (16) and a rear side (18), a security feature (14) applied to the rear side (18) and an intaglio printing motif (12, 20) subsequently applied to the front side. According to the invention the intaglio printing motif includes at least one embossed elevation (20E) opposite the security feature (14) which protects at least a partial region of the security element (14) during the intaglio printing step.
There is described a method for applying a colored or colorless micropattern to a support, in which a die form is prepared whose surface exhibits an arrangement of elevations and depressions in the form of the desired micropattern, the depressions in the die form are filled with a curable colored or colorless lacquer, the support is pretreated for a good anchoring of the colored or colorless lacquer, the surface of the die form is brought into contact with the support, the lacquer that is in contact with the support in the depressions in the die form is cured and, in the process, joined with the support and the surface of the die form is removed from the support again such that the cured lacquer that is joined with the support is pulled out of the depressions in the die form.
An apparatus for optical analysis of value documents (BN) possesses a recording area (14) in which a value document (BN) is located during analysis, and a spectrographic device (16). The latter has a spatially dispersing optical device (29) for at least partly decomposing optical radiation coming from the recording area (14) into spectrally separate spectral components propagating in different directions according to the wavelength, a detection device (30) locally resolving in at least one spatial direction for detecting the spectral components, and a collimating and focusing optic (28) for collimating the optical radiation directed from the recording area (14) onto the dispersing device (29) and for focusing at least some of the spectral components formed by means of the dispersing optical device (29) onto the detection device (30).
The invention relates to a security element with an optically variable structure having an embossed structure with linear embossed elements and a coating, the embossed structure and the coating being so disposed that at least parts of the coating are completely visible upon perpendicular viewing but concealed upon oblique viewing. Since substantially the total coating is formed from nonlinear primitives which are characterized by the parameters of outline form, size, color and orientation, and so combined with the embossed structure that different information is visible upon a change of viewing direction, the falsification security of the security element can be increased. The invention relates further to a method for producing such a security element, to a data carrier having such a security element, and to the use of such a security element or data carrier for product protection.

SECURE DOCUMENT OF VALUE AND METHOD OF MANUFACTURING SAME
A secure document value includes a sheet-like substrate and a thin film, optically variable security device on the substrate. The security device includes a carrier and a multilayer coating on the carrier. The multilayer coating includes a dielectric-metal stack having an exposed reflective layer that is tailored after manufacture to include security data proprietary to the issuer of the document of value thereby to deter forgery. Since the security device is tailored after manufacture, the end supplier of the document of value does not need to provide the proprietary information to the manufacturer of the security device for incorporation therein. This also enables the manufacturer of the security device to stockpile material until such time the material must be customized to include security data. This results in shorter lead times and better response to market demands.
