The invention relates to a method for producing a security element (55) and to a security element (55) in the form of a multilayered film body having a top side facing the observer. The security element (55) has a volume hologram layer, in which a volume hologram is recorded, which provides a first optically variable information item. The security element (55) has a replication layer, in the surface of which a relief structure providing a second optically variable information item is molded and which is arranged above the volume hologram layer. A partial metallic layer is arranged between the volume hologram layer and the replication layer, wherein the metallic layer is provided in one or a plurality of first zones of the security element and the metallic layer is not provided in one or a plurality of second zones of the security element.

The invention relates to a process for the production of a multi-layer image, preferably a multi-color image. A transfer film which is applied to a paper ubstrate and which is treated with laser irradiation is used. The transfer film has a laser-sensitive layer and a background layer arranged therebeneath. The laser-sensitive layer comprises laser-sensitive material, for example laser-sensitive pigments or other laser-sensitive coloring agents. The laser-sensitive material in the layer is region-wise bleached by laser irradiation. That results in a so-called laser-induced image component. As it is transparent or partly transparent, the background layer which is arranged therebeneath and which can have a printed image then becomes visible from above in that region. That therefore gives a multi-layer image which is formed by the laser-induced image component and by the background layer jointly.

The present invention relates to a multi-layer body which is a paper document with a hot stamping film embossed thereon. The hot stamping film has a laser-sensitive layer in which a laser-induced color image is produced by laser treatment. Arranged on the document are further security identifications such as a security print, which is in the form of guilloche patterns, fluorescent threads, and a security strip. Water marks are also provided in the paper document.

The invention concerns a value-bearing document and a process for the production of a value-bearing document. The value-bearing document comprises a carrier of a paper material and a laminating film which is applied to the carrier and which has a carrier film and a decorative layer arrangement including one or more security features and/or one or more components with electrical functionalities. The laminating film is provided with predetermined breaking locations the reducing the strength of the laminating film.

A process for the production of a multi-color image is described. Preferably a transfer film is used which has a laser-sensitive layer (4). The laser-sensitive layer (4) comprises a three-component mixture. The components are coloring agents which are bleachable with laser radiation, in particular pigments, for example cyan pigment, magenta pigment and yellow pigment.With the process the procedure is such that in the individual steps only a respective one of the pigment components is bleached insofar as the laser conditions which are respectively specific to the various pigment components are set. This means that in the case of the three-component mixture only a first component is bleached by laser treatment of a given location in a first step by laser irradiation and only one other component is bleached in an optional second step and only one third component is bleached in an optional third step. The color at the location in question is afforded in each case by subtractive color mixing of the remaining unbleached components.

The invention concerns an apparatus and a process for producing a marking on a substrate. Substrates marked in that way are applied to documents such as for example credit cards, personal identity cards or banknotes as security features to provide protection from forgery. Embodiments of those security features have diffractive or holographic structures. The production of the markings was hitherto effected by shaping from a mold. A change in the marking is possible by changing the mole, which is time-consuming. The new apparatus and the new process are intended to permit the production of individualized markings on a substrate, at a low level of apparatus expenditure.An embodiment of the apparatus according to the invention for producing a marking on a substrate, preferably a film, has a replication apparatus and a laser installation, which co-operates with the replication apparatus, by radiation from the laser installation being directed onto at least one irradiation region of the replication apparatus, for producing at least one shaping region. The apparatus further has a counterpressure apparatus, wherein a substrate is arranged between the replication apparatus and the counterpressure apparatus in order to shape the shaping region onto the substrate in a contact region between the replication apparatus and the substrate and wherein the feed of the radiation for producing the shaping regions extends outside the substrate.

Embodiments of these security features have diffractive or holographic structures. Production of the markings is produced by shaping from a mold. A change in the configuration of the marking is possible by changing the mold, which is time-consuming. The new apparatus and the new process are intended to permit the production of individualised markings on a substrate at a low level of apparatus expenditure. The new apparatus has a replication apparatus, in the form of a replication roller, having a replication surface, a device for producing a radiation and a counterpressure apparatus with a counterpressure surface, wherein a substrate is arranged between the replication surface of the replication apparatus and the counterpressure surface of the counterpressure apparatus in such a way that a shaping region of the replication surface is shaped on to the substrate in a contact region between the replication surface and the substrate.

Described is a multi-layer body having two laser-sensitive layers 4, 32. The multi-layer body is a body laminated from the overlay films 30, 32, the inlets 90, 90 and the further overlay films 30, 30. At its underside the upper overlay film 30 has a layer structure applied there, by the application of a hot stamping film. The layer structure comprises a lacquer layer 50, a reflection layer 5r, a laser-sensitive layer 4, a background layer 5 and an adhesive layer 6. A diffraction and/or hologram structure 5b is provided in the lacquer layer 5c, the reflection layer 5r and the laser-sensitive layer 4. The second laser-sensitive layer is formed by the carbon-doped overlay film 32. By means of laser treatment, it is possible to produce a laser-induced, preferably colored image component in the upper laser-sensitive layer 4 and a further laser-sensitive image component, preferably in the form of a gray scale image, in the subjacent carbon-doped laser-sensitive layer 32. A laser-induced multi-layer image is formed in that way.
