Patent number: 7403651Abstract: 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.Type: GrantFiled: November 2, 2001Date of Patent: July 22, 2008Assignee: Leonhard Kurz GmbH & Co.

Patent number: 7401550Abstract: 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.Type: GrantFiled: August 5, 2003Date of Patent: July 22, 2008Assignee: Leonhard Kurz GmbH & Co.

Patent number: 7368217Abstract: 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.Type: GrantFiled: May 8, 2002Date of Patent: May 6, 2008Assignee: ORGA Systems GmbHInventors: Norbert Lutz, Gerhard Zinner, Matthias Schumacher, Ulrich Knaack, Dirk Fischer

Patent number: 7357075Abstract: 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.Type: GrantFiled: August 8, 2003Date of Patent: April 15, 2008Assignee: Leonard Kurz GmbH & Co.

Patent number: 7300694Abstract: 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.Type: GrantFiled: May 8, 2002Date of Patent: November 27, 2007Assignees: Leonard Kurz GmbH & Co.
