Patent application numberDescriptionPublished
20080241492Ir-Absorbing Intaglio Ink - Pasty ink for the engraved steel die printing process, having a viscosity value above 3 Pa·s, preferably above 5 Pa·s at 40° C., and comprising an infrared absorbing material, wherein said infrared absorbing material is a transition element compound whose IR-absorption is a consequence of electronic transitions within the d-shell of transition element atoms or ions.10-02-2008
20090184169Coating Composition for Producing Magnetically Induced Images - The present invention is related to a coating composition for the production of a magnetically induced image, consisting of volatile components (S) and non-volatile components, the latter consisting of an ink vehicle (I) and magnetically orientable optically variable interference pigment (P), to a process for manufacturing the coating composition, and to the use of the composition for the production of a magnetically induced image coating on a substrate with the help of applied magnetic fields. Said magnetically induced image coating may be used as a security device on value- or identity documents, brand protection labels and the like.07-23-2009
20090200791Oriented Image Coating on Transparent Substrate - The present invention discloses a security element comprising a transparent substrate and a magnetically oriented image coating on said substrate, wherein said image coating is preferably laid out such as to show a 3-dimensional effect, appearing in positive or negative relief respectively, if observed form the recto- or the verso side, respectively. The security element can be easily identified by the unaided eye, by just turning around the document and observing the angle-dependent image on either side. On the other hand, the security element cannot be reproduced by scanning or copying the document.08-13-2009
20090278345Black-to-Color Shifting Security Element - The invention discloses a security element for a banknote, a document of value, right or identity, a ticket, a label, a branded good identifier, or a tax banderole. The element comprises a combination of a coating containing at least one optically variable pigment having a substantial viewing-angle dependent color variation, with at least one selective spectral absorbing material, which blocks out visible spectral components reflected by the optically variable pigment at orthogonal incidence. The security element appears black when viewed at orthogonal angle, and colored when viewed at grazing angle.11-12-2009
20100040845Method and Means for Magnetically Transferring Indicia to a Coating Composition Applied on a Substrate - The invention concerns a device for magnetically transferring indicia, such as a design or an image, to a wet coating layer applied on a substrate, such as a sheet or a web, wherein the said coating layer comprises at least one type of magnetic or magnetizable particles; said device comprising a) at least one magnetized permanent-magnetic plate (02-18-2010
20110298207MAGNETICALLY ORIENTED INK ON PRIMER LAYER - Disclosed is a security document (D), having a substrate (S) coated with at least one first coating layer (P), and over said first coating layer (P) at least one second coating layer (I), said second coating layer (I) comprising at least one type of magnetic or magnetizable particles (F), wherein indicia are embodied in the coating layer (I) through a selective orientation of the said magnetic or magnetizable particles (F). Further disclosed is a process of making said security document.12-08-2011
20120055355MAGNETIC ORIENTING AND PRINTING - The invention discloses a device and a process for producing indicia comprising magnetically oriented magnetic or magnetizable particles in an ink or coating composition on a sheet of substrate material. The device comprises a flat-bed screen-printing unit having a flat printing screen and a printing platen for receiving said sheet, the printing platen having an upper surface facing the printing screen and a first direction along its upper surface along which said sheet is unloadable, and a magnetic orienting unit comprising multiple magnet assemblies. The magnetic orienting unit is disposed below the upper surface of the printing platen, said multiple magnet assemblies are disposed along said first direction, and all of said magnet assemblies are concomitantly movable from a first position away from the upper surface of the printing platen to a second position close to the upper surface of the printing platen.03-08-2012
20120065313IR-ABSORBING INTAGLIO INK - Pasty ink for the engraved steel die printing process, having a viscosity value above 3 Pa·s, preferably above 5 Pa·s at 40° C., and comprising an infrared absorbing material, wherein said infrared absorbing material is a transition element compound whose IR-absorption is a consequence of electronic transitions within the d-shell of transition element atoms or ions.03-15-2012
