A description is given of a document with a hologram as a security feature, in particular an identity card (), consisting of a polycarbonate card body (), which has a volume hologram label () embedded therein. A description is additionally given of a method for producing the document, in which volume hologram labels () arranged on a carrier sheet are brought into contact with adhesive regions () on a thermoplastic sheet (), the adhesive surfaces are cured and the carrier sheet is then removed. A second plastics sheet () is then adhesively bonded onto the first plastics sheet (), bearing the hologram labels, using a second adhesive () in the region of the hologram labels () to form a two-layered sheet composite () which, finally, is laminated, together with further thermoplastic sheets, in a card-lamination press, under the action of pressure and temperature, to give a card body (), individual identity cards () being punched out.

Document with hologram, and method of producing same

When coating a document surface () having relief-like information () carrying personal data, for example, with a monomer-containing liquid UV adhesive () across the entire surface and then laminating thereon a volume hologram (), the varying adhesive thicknesses between the volume hologram and the document surface resulting from the relief cause differentiated swelling and thereby a differentiated color shift of the hologram. After the desired color shift is achieved, the UV adhesive () is completely cured. In this way, individual holographic information is obtained, which is located exactly above the relief-like information of the document. With this method, holographic overlays comprising personal data and a passport picture can be produced, and it is possible to link defined optical document information to the hologram in an accurately positioned manner, so that information is visible both non-diffractively and, from a different viewing angle, holographically in a different color.

Method for producing security elements by the individualization of volume holograms and security elements produced therewith

A multi-layer body includes a carrier film, a release layer, an embossed hologram layer, and a vapor-plated reflection layer. An adhesive layer is UV activated and includes a partially activated zone. Cured adhesive regions connect a transparent polycarbonate film and parts of the embossed hologram layer to one another inseparably. The cured adhesive regions are arranged about the periphery of an uncured adhesive region of the adhesive layer to form a frame around the uncured adhesive region. A forgery-proof document is produced using the multi-layer body. Uncured adhesive regions of the multi-layer body are partially cured with UV light through an information-carrying optical mask. The carrier film is removed together with the release layer and non-bonded embossed hologram layer regions. An upper protective film is applied to individualized embossed hologram layers and is hot pressed together with additional films.

Multi-layer body, method for producing it, and production of forgery-proof documents using said multi-layer body

The invention relates to a method for the individual application of a hot embossing film, according to which an adhesive is printed on a substrate in the form of symbols, patterns, numbers etc., then a hot embossing film consisting of a backing film, peel-off layer and decorative layer is hot-laminated on the printed substrate and the backing film is removed.

Method for the individual application of hot embossing film and security documents produced therewith

A production method is provided by which a copied volume hologram from a multi-layer master is later customized by utilization of the color tuning properties of the light-curable materials used for the application onto personal documents. These holographic individual data, such as a passport photo, are also separately detectable, without the holographic elements copied from the master, that are visible under other viewing angles, impairing the visibility of the individual data. The volume hologram overlay obtained by this method is applied on personal and valuable documents to increase protection against forgery, possesses superimposed optically variable items of information that are separately visible under different viewing angles and give a defined color change under different view angles, wherein at least one of these items of optical information represents individual personal data, in particular a passport photograph.

Method for producing counterfeit-proof confidential and valuable documents

The invention relates to a security system especially for security documents, wherein a security element is provided in a carrier plane, that under incident light holographically reconstructs a pattern outside the carrier plane, in which concealed information is stored and having a flat transparent verification element which on flat contact with the security element makes the information stored therein visible. The invention further relates to a security element and a verification element for use in the security system and a security document fitted with the security system. The invention additionally relates to an apparatus and a method for reading out the concealed information which is stored holographically in the pattern reconstructed on the security element under incident light.

Security system, particularly for valuable documents

In a method for production of documents with a hologram and a document with a hologram, wherein, in a first step, a hologram is exposed in a photographic film and, in a second step, the photographic film is applied to a document support, the individualisation of the holograms first occurs during the gluing or after the gluing to the printed personal document or to the protective film provided for the surface protection of the document. It is thus possible to produce in a secure and economical fashion documents with individual holographic information of greater visibility and with further novel security features.

Method for production of documents with a hologram and a document with a hologram

Security system, especially for security documents

A method for producing an optical element, preferably a security feature, wherein a film having a first embossed hologram in an embossing layer is provided, and a second embossed hologram is embossed into the same embossing layer such that the first embossed hologram is partly replaced with the second embossed hologram. The invention further relates to a method for producing an optical element wherein an embossable film provided with an embossed hologram is partly filled with printing lacquer, and a method for producing an optical element wherein hologram embossing is prevented by prior partial printing of the embossing film with curable printing lacquer. The invention relates further to optical features producible by the inventive methods, documents of value having an inventive optical feature and a numbering embosser for use in an inventive production method.

Optical element and method for the production thereof

The invention relates to an optical feature, in particular for documents of value, having at least one at least dual-channel hologram for the holographic reconstruction of different images from different directions of gaze, wherein different regions of the hologram are associated with the different channels and the regions of the hologram reconstructing the respective image under incident light have sub-regions which do not take part in the image reconstruction, to a data carrier having at least one optical feature of the invention and to a method for the manufacture of an optical feature, in particular for documents of value.
