Definitions

  • the invention relates to a security paper with a Security element in the form of a thread or tape, the from a translucent plastic film with at least partial opaque coating and one Information in the form of visual and / or machine has legible characters or patterns.
  • security threads secured against counterfeiting. Papers of this type are referred to below as security papers become.
  • the security threads used for this consist of various materials in the form of Threads or tapes with a width of 0.4 to 10 mm. They mainly consist of plastic films, which metallic coated, printed, colored or even e.g. B. are provided with pigment-shaped substances.
  • the security threads by selecting appropriate substances, magnetic, fluorescent, x-ray absorbing and others To give properties.
  • Metallic coated threads have been used recently increasingly used for security papers. These threads, which are partially or entirely inside the Papers are arranged in striking light almost invisible. Because that through the top layer of paper urgent light rays are on the metallic Surface completely reflected and in the paper diffusely scattered. Such appear in transmitted light Threads, on the other hand, as black stripes that differ from theirs Stand out clearly from the surroundings. Threads of this type can pass through a imprint on the paper cannot be imitated.
  • For Counterfeit protection has also been increased proposed such aluminum-coated security threads to be provided with a micro script (DE-A-14 46 851). In practice, however, this has turned out to be little expediently emphasized, since this font on the otherwise opaque security thread in transmitted light is not and is very difficult to see in reflected light. Self if such security threads, as in EP-A-0 059 056 described as so-called window threads in the paper is inserted, the microprint remains in the printed paper difficult to find.
  • a security thread is known from EP-A-0 279 880 transparent film material known, on which metallic glossy micro characters are provided.
  • the micro characters are, because of the complete Embedding the thread in the banknote, not in incident light recognizable. In transmitted light, however, are exclusive only the characters are recognizable as the security thread itself is transparent. The viewer so only the banknote is shown in transmitted light continuous lettering, because of the small size of the Characters, its embedding in the pulp and possibly a printed image above it is difficult can be found. The imitation of such a thread is on the other hand because of the small size of the micro characters difficult.
  • Security thread becomes a translucent plastic film, which can be colored, with a full surface opaque, especially metallic coating provided in the recesses in the form of characters or Patterns are generated.
  • the thread is in transmitted light as Dark streaks can be seen in the document while the Characters and patterns compared to their immediate surroundings, the opaque thread coating, and also opposite the wider environment, the documentary material, stand out clearly as bright, possibly colored areas.
  • the thread is very easy to find in the document and the characters are always of the appropriate size readable even without tools.
  • Such a thread is used as a window thread in a Introduced security paper, so he offers in the area the window an additional copy protection, since the metallic luster of the coating from a copier cannot be reproduced and therefore the copy of this Areas in black.
  • the invention is based on the object Security paper with a thread or ribbon-shaped Manufacture security element that provides a high level of protection against counterfeiting offers, but at the same time good recognizability the security element and the signs guaranteed without technical aids.
  • the invention Security paper a security thread consisting of a translucent plastic substrate with grid-like metal coating on.
  • This can be, for example, a periodic stripe pattern that is related to the Direction of the thread any orientation can take.
  • this security thread carries a particularly visually readable information that over several opaque, metallic areas as well as metal-free Intermediate areas extends. That is, the information which include any characters or patterns can lie as translucent metal-free Areas in front.
  • This grid-like arrangement of the metal areas has the Advantage that the frequent metal / non-metal changes Imitations of the visual impression, if any are only possible using complex techniques.
  • the information can be the characters and / or patterns also arranged alternately Put together opaque and translucent areas.
  • the translucent ones are Share of information in the area of opaque background coating and the opaque pieces of information in the coating-free translucent intermediate areas, so that the information on the background pattern take off in contrast.
  • the security element according to the invention offers like all metallized security threads, one good copy protection through the well-known incident light / transmitted light effect. Larger coherent metallic Surfaces appear as dark spots in reflected light Paper, so that with the known security elements This visual impression has already been tried imitate. Small metallic areas, like the one in the Metallic characters described in EP-A-0 279 880 are less noticeable in reflected light, but difficult to find even in transmitted light, so that a review this authenticity feature is difficult.
  • the security element according to the invention is due to of the background pattern consisting of approx. 50% opaque areas easy to find and check in paper. Moreover, due to the grid-like Arrangement of the opaque areas and the associated areas frequent changes between opaque and non-opaque Areas imitations of visual impression in reflected light prevented or at least made very difficult.
  • a security document according to the invention here a banknote into which a thread or ribbon-shaped Security element 2 in the form of a window thread is woven so that the thread in certain Distances, the so-called windows 3, directly to the Paper surface occurs.
  • the thread can also be complete be embedded in the paper or as a full surface external element to be executed.
  • the width of the thread can be, for example, between 0.4 and 10 mm.
  • FIGS. 2-8 show a section from a security element according to the invention under supervision.
  • the embodiment shown in Fig. 2 consists of a transparent or at least translucent plastic substrate 3, the one with a striped Metallization 4 is provided. Over several of them A streak extends visually and / or mechanically readable information 5, which is due to the corresponding shaped recesses in the opaque stripes stands out from this background.
  • the metallic stripes 4 can for example have a width of 200 microns and with respect to the running direction of the thread by 45 ° have inclined orientation while the font weight the contrasting information is 600 ⁇ m can.
  • the example shown in Fig. 2 has one coating-free edge area 6, which during the Production of the threads in web form as a cutting tolerance serves and in particular as a window thread for a uniform appearance of the thread in the window area. On this edge area 6 can in the production of fully exposed or embedded threads are dispensed with.
  • the orientation of the metallic strips is arbitrary selectable and in a further preferred embodiment 0 ° with respect to the running direction of the thread, as shown in Fig. 3. The same applies of course for the selected stripe widths and font weights.
  • the information can also be opaque and translucent Areas that differ from their respective Lift off the surroundings, put them together. Such variants show FIGS. 4-8.
  • Fig. 4 shows a similar background pattern as Fig. 2, d. H. opaque at 45 ° to the direction of the thread Metal strips with a width of 400 ⁇ m in the area of Signs have correspondingly shaped recesses 9. Inverse to this get the in the coating-free Information portions 7 an between areas opaque coating, which is also strip-shaped and has the same angular orientation.
  • Fig. 5 shows the analog case for a parallel to Direction of the thread running stripe-shaped Background pattern.
  • FIG. 6 Another alternative is shown in FIG. 6.
  • the plastic substrate 3 is in two Subregions arranged parallel to the thread running direction subdivided.
  • the upper area includes the metallization 4, in which the translucent portions 9 of the Information is provided.
  • the opaque pieces of information 7 are in the lower coating-free Area 8 of the plastic substrate 3.
  • Fig. 7 offers another variation.
  • Plastic substrate 3 with two symmetrical to the middle of the thread arranged metal strips running along the thread 4 provided the z. B. a width of approx. Own 1.3 mm. These strips are separated by an approx 1 mm wide coating-free area 8 from each other Cut.
  • the information superimposed on this background pattern has a font size of about 3 mm, one Font size of 600 ⁇ m and extends across all three background areas. Be in the metal beam 4 the information portions are shown in the form of cutouts 9, while those in the coating-free area 8 located parts 7 of opaque coating material consist.
  • Fig. 8 shows another embodiment of the composite Information in front of a partially metallized Background.
  • the background of metallic bars 4 formed on the checkerboard the plastic substrate 3 are arranged.
  • the readable Information is set up analogously to that described above Variants of recesses 9 and metallic Areas 7 together and extend in the transverse direction of the thread seen side by side over at least one pair arranged metallic / metal-free areas.
  • the metallized information 7 and the metallic background areas 4 with different metals of different colors to design.
  • one Metallization or metallic printing ink also others when viewed in transmitted light to the environment in color and / or non-metallic contrasting in gray tone Layers such as B. opaque, preferably white layers of paint, shiny metallic layers, such as B. Nitride or interference layers, find application. Interference pigment-containing printing inks are also conceivable.
  • the plastic substrate with non-covering, preferably translucent printing inks in different Colors and tints can be provided.
  • the slide can but also dyed with appropriate colorants be that in a portion of the visually accessible The spectrum remains transparent.
  • luminescent colors can either be colorless when not excited or have a body color that is preferred differs from the color of the emission light.
  • the Characters or patterns only appear in the Excitation light colored or change color when the Thread z. B. is viewed under UV light.
  • Several in different colors emitting luminescent substances increase both the design possibilities as well the counterfeit security, since for exact imitation Analysis of each individual luminescent substance necessary is. This analysis can easily go further are made more difficult by the different luminescent colors mixed or overlapping printed.
