| 20100073646 | METHOD FOR THE PRODUCTION OF A MULTI-COLOUR VOLUME HOLOGRAM, A DOCUMENT WITH SUCH A HOLOGRAM, AND A VOLUME HOLOGRAM MASTER - The invention relates to a method for the production of a multicolor hologram by means of a capture beam, wherein the utilized capture beam ( | 03-25-2010 |
| 20100202028 | Method for producing counterfeit-proof confidential and valuable documents, master for use in this method and confidential and valuable 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. | 08-12-2010 |

| 20100195176 | SECURITY SYSTEM, PARTICULARLY FOR 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 fiat transparent verification element which on fiat 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. | 08-05-2010 |

| 20090262407 | Method for Production of Documents with a Hologram and a Document with a Hologram - 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. | 10-22-2009 |
