Patent number: 9200204Abstract: The present invention relates to a marking of polymeric liquid crystal material having determined optical characteristics allowing its authentication and reading by a machine and its authentication by the human eye. The marking is applied onto an item, good or article by a variable information printing process. The marking is in the form of indicia representing a unique code which allows for an easy authentication by the human eye and a secure tracking and tracing of the marked item, good or article throughout is life cycle.Type: GrantFiled: April 6, 2010Date of Patent: December 1, 2015Assignee: SICPA HOLDING SAInventors: Xavier Marguerettaz, Frederic Gremaud, Aurelien Commeureuc, Vickie Aboutanos, Thomas Tiller, Olivier Rozumek

Patent number: 8821756Abstract: The present invention relates to a marking on an item or substrate, which marking is based on a chiral nematic (also called cholesteric) liquid crystal precursor composition. Prior to curing the chiral liquid crystal precursor composition in the chiral liquid crystal state at least one optical property exhibited by the composition is modified by two modifying agents of different types in at least one area of the item or substrate.Type: GrantFiled: May 24, 2012Date of Patent: September 2, 2014Assignee: Sicpa Holding SAInventors: Thomas Tiller, Olivier Rozumek, Tristan Jauzein, Andrea Callegari, Frédéric Gremaud, Brahim Kerkar
