Abstract: Described is a laminate body, in particular a laminate foil, comprising a laser-sensitive layer and an identification element, for example a diffraction and/or hologram structure, a reflection layer, a printed image or the like, which is provided in a second layer and/or in the laser-sensitive layer, wherein the laser-sensitive layer has a marking produced by laser action, which is positioned in accurate register relationship relative to the identification element In addition the subject of the invention is a method of enhancing the forgery-proof nature of such a laminate body in which the laminate body is irradiated by means of a laser so that produced in the laser-sensitive layer is a laser-induced marking positioned in accurate register relationship with the position of the identification element.

Abstract: The present invention relates to a process for increasing the level of safeguard in respect of forgery of paper documents. For that purpose, applied to the paper document is a transfer film or laminating film having a laser-sensitive layer. This multi-layer body is then treated with laser radiation. In that case, a laser-induced marking is produced in the laser-sensitive layer, for example, by laser-induced bleaching, laser-induced color change or laser-induced blackening. Respective individualization of the document can be effected by way of that laser-induced marking.

Abstract: 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.

Abstract: The invention concerns a film (1), in particular a stamping or laminating film, and a process for the production of such a film. At least one component produced using organic semiconductor technology, in particular one or more organic field effect transistors, is integrated into a film (1).

Abstract: A security element for RF identification and a process for the production of such a security element. The security element has a flexible, electrically non-conducting substrate layer and a conductive layer of an electrically conducting material which is applied to the substrate layer and which in a first surface region of the substrate layer is shaped out in pattern form to form an RF component. A first relief structure is shaped at least in region-wise manner in the surface region, associated with the RF component, in the first conductive layer.

Abstract: 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 for affording protection from forgery. 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.

Abstract: 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 substrate 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.

Abstract: 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.

Abstract: 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.

Abstract: Proposed are stamping foils and processes for the production thereof, which make it possible to form on a carrier film patches which are completely separate from each other and which can be transferred on to a substrate using the procedure which is usual when dealing with stamping foils, wherein the transfer operation can be effected in such a way that no flakes which interfere with subsequent overprinting are formed.

Abstract: A cushioning or padding body for insertion into footwear, a method of manufacturing the body and a method for the simultaneous manufacture and exact fitting of the body to the respective shape of a corresponding part of the foot of the wearer are related. The body comprises a plurality of individual foam material beads alone or a mixture of a plurality of individual foam material beads and a resiliently cushioning, thermoplastically non-deformable plastic material. The beads are each provided with a closed surface and each is generally impermeable to air. The beads are fixed in their position relative to each other by the effect of that.
