Abstract (en)
[origin: EP2251207A1] The marker has a carrier substrate (1) deposited on two partial layers (3, 4), where the layers have different colors or color impressions and include partial transparent recesses. The layers are absolutely identical to each other applied without tolerances. The layers have different thicknesses and stoichiometries, where the marker includes diffractive layers, liquid crystal layers, colored layers and luminescent layers with electrically conductive and magnetic characteristics. The layers are made of aluminum, copper, silver, iron, gold, chromium, nickel, zinc, cadmium, bismuth, tin, titanium dioxide, chromium oxides, zinc sulfide, indium tin oxide, bismuth-oxide, antimony tin oxide, fluorinated tin oxide, zinc oxide, aluminum oxide, non-stoichiometric aluminum oxide, zinc chromate, iron oxides, copper oxides, non-stoichiometric copper oxide, silver oxides, copper-aluminum alloys, copper-zinc alloys, iron alloys, steel, malachite or Azurite. An independent claim is also included for a method for preparing a safety marker.
