Identifikationselement

DE 102006017155 A1 UPAB: 20071119 NOVELTY - The identification unit has a structural unit formed as a coating on a substrate. The identification unit is detected by an electromagnetic radiation in a tera-hertz frequency region. The coating has a thickness smaller than 50 nanometer and an electrical conductivity of 100 siemens per meter. The maximum thickness of the coating is kept at 15 nanometer. The coating is composed of aluminum, copper, gold, silver, cobalt, nickel, iron and alloy of metals. The structural unit has a substructure for producing diffraction and interference effects. USE - Used in a label for identifying an article e.g. valuable piece of luggage or parcel and high-quality textile. ADVANTAGE - The coating has a thickness smaller than fifty nanometer and the electrical conductivity of hundred siemens per meter, thus improving falsification and manipulation security of the identification unit to provide a safe detection of the identification unit for identifying the articles
