Patent number: 10703127Abstract: The present invention relates to the field of the intaglio printing process. In particular, the present invention relates to a method that combines intaglio inks curable by oxidation with UV-VIS-curable intaglio inks on one intaglio plate or cylinder. The disclosed method results in an intaglio printed security element using advantageously the unalike properties of the different inks while enabling the printing on a standard printing press in one printing step.Type: GrantFiled: November 21, 2019Date of Patent: July 7, 2020Assignee: SICPA HOLDING SAInventors: Olivier Lefebvre, Patrick Magnin, Christophe Schaller, Pierre Degott, Jean-Daniel Spitteler

Patent number: 9724957Abstract: The present invention relates to the field of the protection of security documents, especially banknotes, against illegal actions such as robbery or theft. In particular, the present invention relates to the field of ink compositions for producing irreversibly magnetically induced images or patterns, said inks comprising multichromal microspheres, preferably bichromal microspheres (1) that are orientable upon application of a magnetic field and that comprise at least a first portion (2) comprising one or more dyes and/or pigments and at least a second portion (3) comprising one or more magnetic or magnetizable materials, wherein said microspheres (1) comprise as the first portion a core (2) having a surface and comprising the one or more dyes and/or pigments and as the second portion a partial coating (3) covering at least a portion of the surface of said core (2) and comprising the one or more magnetic or magnetizable materials.Type: GrantFiled: October 22, 2013Date of Patent: August 8, 2017Assignee: SICPA HOLDING SAInventors: Olivier Lefebvre, Patrick Magnin, Christophe Schaller

Patent number: 8540813Abstract: An ink for the engraved copperplate intaglio printing inks is disclosed, which comprises high-molecular-weight dendritic polymer as a binder component. Inks comprising such polymer can be formulated so as to contain a significantly reduced amount of organic solvent (volatile organic components, VOC) while still being in the appropriate viscosity range required by the intaglio printing process. The printed and cured intaglio ink of the present invention has improved chemical and mechanical resistance properties.Type: GrantFiled: June 23, 2009Date of Patent: September 24, 2013Assignee: Sicpa Holding SAInventors: Anne Grosset, Olivier Lefèbvre, Christophe Schaller, Nicolas Trachsel, Patrick Magnin, Patrick Veya
