摘要:
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.

摘要:
Re-dispersible pigmented printing ink compositions, preferably for the continuous ink jet printing process are obtained by the addition of a flocculating agent to the pigment dispersion in the printing liquid. The compositions do not form hard sediments and are easy to re-disperse on stopping and resuming the printing operations. Suitable flocculating agents bind the pigment particles in the sediment into three-dimensional “airy” structures, which are easy to break up. The ink compositions of the invention are furthermore characterized by a good printability in the dispersed state.

摘要:
A tamperproof case for a genuine article which comprises a space for accommodating the article between first and second sheet members which are capable of being permanently bonded together in at least the area that substantially completely surrounds the space. At least one of the first and second sheet members comprises at least one security element that is invisible under light in the visible wavelength range. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
