  • either the visible marking or the machine-readable marking usually stands in the foreground, while the respective other aspect is perceived as disturbing.
  • the machine-readable Markers are therefore often laminated or hidden optically, while the visually recognizable markings typically do not have sufficient machine-readable properties for secure detection.

  • the outer layer of the multilayer pigments is at least partially ablated or removed. The marking is brighter in the visible spectral range than the background range and thereby visually detectable, while the marking in the infrared spectral range has a greater absorption than the background area and is thus mechanically detectable.
  • the inner layer may, for example, be magnetic and based on Fe 3 O 4 , gamma iron oxide or maghemite, with alkaline earth oxide, in particular MgO, doped gamma iron oxide, Co-containing gamma iron oxide, Co-containing Fe 3 O 4 or CrO 2 .

  • first infrared absorption is suitably more than 1.25 times, preferably more than 2 times, more preferably more than 5 times, and most preferably more than 8 times as large as the aforementioned "second infrared absorption".
  • infrared absorption suitably refers to a wavelength range of 800 to 1400 nm, preferably 800 to 1200 nm, and more preferably 800 to 1050 nm.

  • the proportion of the alkaline earth metal is for example 0.01 to 2 wt .-%, in particular 0.1 to 1 wt .-%, based on the total pigment.
  • the layer applied on the carrier may consist exclusively of the gamma-iron oxide doped with alkaline-earth metal oxide, in particular MgO.
  • the gamma iron oxide may also contain other iron compounds, for example Fe 3 O 4 or alpha iron oxide. The last two compounds are in the gamma-iron oxide layer, individually or in combination, preferably in a proportion of at most 25 wt .-% based on the gamma-iron oxide.
  • a dielectric layer may be arranged above the gamma-iron oxide-deposited layer on the carrier.

  • a motif resulting from a magnetic alignment may be independent of the laser-generated marking or interact with it.
  • the tag may form a static reference point for a dynamic motion effect of the magnetic motif.
  • multilayer magnetic pigments can also be used without magnetic alignment of the pigments.
  • the multilayer pigments used according to the invention are preferably not optically variable, ie they preferably exhibit a uniform color substantially independent of the viewing angle.
  • the pigments can show shiny metallic colors, in particular gold, copper or bronze tones.
  • Such pigments are for example in the WO 2010/149266 A1 disclosed.
  • the effects according to the invention also occur even when the color layer, in addition to the multilayer pigments and a binder, contains not too large a proportion of optically variable pigments.
  • the color layer in addition to the binder, contains 75% to 100% of the described non-optically variable, multi-layered pigments and from 25% to 0% optically variable pigments.
  • the laser application is carried out with a pulsed infrared laser in the wavelength range of 0.8 .mu.m to 3 .mu.m, preferably with short pulse durations of 25 ns or less, in particular from 8 to 18 ns.
  • FIG. 1 shows a schematic representation of a banknote 10 with a printed directly on the banknote paper security element 12th
  • the peculiarity of the security element 12 is particularly evident in the infrared spectral range.
  • the label 18 in the infrared spectral region has a significantly higher absorption than the background region 16 and is thereby easily and reliably detectable by machine, for example with an infrared sensor 22 sensitive at a wavelength of 850 nm.
  • a first effect typically occurs in the visible and infrared spectral regions relatively strongly absorbing ink layers.
  • the absorption 30 of such a color layer in the visible spectral range (VIS) and its absorption 32 in the infrared spectral range (IR) are shown schematically. If such a color layer is irradiated with pulsed laser radiation of sufficient intensity, the color layer is locally destroyed or desorbed by the laser radiation so that the substrate or an underlying printing layer becomes visible.
  • the absorption by the color layer in the lasered region generally decreases both in the visible spectral range 34 and in the infrared spectral range 36, resulting in a bright identification with reduced IR absorption, as in the right half of FIG Fig. 3 shown schematically.
  • the size of the absorption before the laser application is shown with dashed lines for easier orientation.
  • Some colors also show a virtually unchanged absorption in the visible spectral range and a reduced absorption only in the infrared spectral range. Such colors are described, for example, in the document WO 2007/110155 A1 in connection with the local FIG. 3 described. They are well suited for generating machine-readable encodings whose existence is hidden in the visible spectral range.
  • the carbonized material absorbs in a broadband manner, the change in absorbance in the visible spectral region 44 and in the infrared spectral region 46 is usually the same and a visually black high infrared absorption label is produced as in the right half of FIG Fig. 4 shown schematically.
  • the behavior of the ink layer of the invention 14 In contrast to these two conventional effects is the behavior of the ink layer of the invention 14.
  • the absorption 50 of the color layer in the visible spectral range (VIS) and the absorption 52 in the infrared spectral range (IR) is shown.
  • VIS visible spectral range
  • IR infrared spectral range
  • a color layer 14 according to the invention is irradiated with pulsed laser radiation of suitable intensity, a brightening results locally, ie a lower absorption 54 in the visible spectral range, while at the same time a high absorption 56 is produced in the infrared spectral range, as in the right half of FIG Fig. 5 shown.
  • the visually visible, bright mark 18 is set in this way a machine-readable mark with very clear and thus easily detectable infrared contrast. In this way, a multi-level authenticity feature is created, on the one hand due to its light color and the partial preservation of the starting color of the ink layer 14 a Visually attractive appearance and on the other hand, both for the layman easy to identify, as well as mechanically proven to prove.
  • the ink layer 14 contains multi-layered pigments 60 having a uniform color independent of the viewing angle.
  • the pigments 60 are gold-colored and comprise a carrier 62, for example made of Al 2 O 3 , which is coated with an inner layer 64, for example of gamma-iron oxide, and an outer layer 66, for example of MgO.
  • the inner layer 64 has a higher, for example by a factor of 4, higher infrared absorption than the outer layer 66.
  • the effect used for the invention may be due to the laser radiation partially or even completely ablating or removing the outer MgO layer 66.
  • the inner layer 64 is destroyed in addition to the outer layer 66 and there is a reduced absorption both in the visible and in the infrared spectral range, as described above Fig. 3 already described.
  • the inner and outer layers 64, 66 need not extend beyond the edge 68 of the pigment, the inner ones and outer layers may instead be deposited separately on the opposite major surfaces of the core 62.
  • Fig. 7 The dependence of the absorption A on the exposure intensity I in the visible spectral range and in the infrared spectral range is in Fig. 7 shown schematically. While the absorption 70 decreases in the visible spectral range with increasing exposure intensity, the absorption 72 in the infrared spectral range according to the model described above due to the exposure of the inner layer 64 first increases, and then decrease with increasing destruction of the gamma-iron oxide layer, with a Exposure intensity 74 reaches a reduced absorption in both spectral ranges and thus a situation as in Fig. 3 is generated.
  • the intensity range which is preferred according to the invention, in which simultaneously a reduced absorption in the visible spectral range and an increased absorption in the infrared spectral range are obtainable, is indicated in the figure by the reference numeral 76.
  • the absolute values of the preferred intensity range depend on the one hand on the pigment 60 used and on the other on the other laser parameters, in particular on the laser wavelength, the pulse duration, the repetition frequency and the speed with which the laser beam is passed over the ink layer during the marking.
  • Suitable absolute values for the intensity to be used according to the invention can be determined in the case of the known basic course of the invention Fig. 7 however, can be determined experimentally by a person skilled in the art for a specific parameter set and a specific pigment 60 by a few experiments.
  • the multilayer pigments used according to the invention may in particular be magnetic pigments which, in addition to the described effect, may be aligned by an external magnetic field in the form of a desired motif.
  • the magnetic pigments are admixed, for example, with a UV-curing lacquer which is screen-printed with the contained magnetic pigments onto the target substrate.
  • the target substrate with the still-movable magnetic pigments is placed in a magnetic field of a desired field distribution and the pigments thereby aligned.
  • the aligned magnetic pigments are now permanently fixed in their orientation by curing the UV varnish.
  • Safety elements with magnetic motifs oriented in the form of a motif show the viewer an effective, three-dimensionally arunutendes appearance with a dynamic movement effect when tilting the security element, which is combined with the static marking described above.
  • the resulting ink layer 14 then has a uniform appearance except for the label 18, as in Fig. 2 (a) illustrated.
  • FIG. 8 shows for illustration a two-layered pigment 80 with a core 82 of gamma-Fe 2 O 3 and a shell 84 of TiO 2 .
  • the core 82 represents an inner layer which has a significantly higher, for example a factor of 3, infrared absorption than the outer TiO 2 shell 84.
  • the pigments shown are also the multilayer pigments in question, which in the WO 2010/149266 A1 are disclosed. These include, for example, an Al 2 O 3 support and a MgO-doped layer of gamma-iron oxide applied above the support.
  • Fig. 9 shows the measured VIS / IR remissions of three inventive, laser-treated security elements.
  • security elements in each case so-called magnetic gold pigments ("magnetic gold", in Fig. 9 also referred to as "M-gold") with an Al 2 O 3 support and a MgO-doped layer of gamma-iron oxide applied above the support.
