Definitions

  • the present invention is concerned with improvements in security articles and papers such as bank notes, cheques, personal identification documents and the like.
  • Whiist traditional security elements have been narrow and of constant widths, it is desirable to use wider elements or ones with varying widths, for aesthetic reasons or because more information/indicia can be applied to the element.
  • binding fibres in discrete regions on the element, as described in -W0 00/39391.
  • the binding is usually achieved by applying an adhesive onto the thread as a design or indicia.
  • the approach outlined in W0 00/39391 is adequate, but the effectiveness of the feature may be reduced by poor paper fibre deposition.
  • the exposed part of the security thread described in this document does not form a visually striking feature of the appearance of the security article in reflected light.
  • a further problem is that there is a continued need to provide ever more secure documents for an increasing variety of uses to prevent counterfeiting, as counterfeiters have greater access to more sophisticated reproduction equipment.
  • the current invention therefore provides a security element for embedding into a security substrate having a matt non-reflective coating applied to only a part of the security element.
  • the invention also provides a security substrate in which a security element has been partially embedded such that regions of the security element are exposed in windows at least in one surface of the substrate, wherein a matt non-reflective coating is applied to only a part of the security element. It has been found that the aforementioned problems may be overcome by selectively applying a matt coating to the wider extremities of the security element, which coating is substantially the same colour as the substrate onto or into which the element is ' to be applied or embedded, thereby masking any areas of uneven fibre deposition and providing further enhancements to the appearance of the security document .
  • the present invention enables an additional level of complexity and security to be built into the security element without compromising the appearance of the thread once it has been embedded into a security document or the like.
  • the matt coating may also have additional machine- detectable functionality such as luminescence or magnetic properties, though it is preferable to use covert properties, such as magnetics, as portions of the matt coating will be covered by fibres.
  • the regions themselves are potentially machine-readable, as stated above, the regions may also conceal other machine-readable materials such as magnetic materials.
  • the matt regions of a security element according to the present invention are substantially invisible to the unaided eye in reflected light when the security element is included into a substrate.
  • the matt regions of the security element may also contain an adhesive to promote adhesion of paper or other fibres within the treated area.
  • the regions will be coated with a matt non-reflective coating substantially the same colour as the substrate into which the security element is to be included.
  • the matt coating may also have additional machine readable or authenticable properties.
  • the current invention seeks to improve and enhance the appearance of the security element in a windowed substrate in reflected light by masking defects that occur during' the substrate making process. To this end, the matt coating is applied in discreet regions to enhance and improve visualisation of the element in non-coated areas.
  • Figure 1 shows a plan view of a first embodiment of a security element according to the present invention having a matt non-reflective coating
  • Figure 2 shows a plan view of a second embodiment of a security element according to the present invention
  • Figure 3 shows a plan view of a third embodiment of a security element according to the present invention.
  • Figure 4 shows a plan view of a fourth embodiment of a security element according to the present invention, which has a constant width with two matt non-reflective areas running along either edge;
  • Figure 5 shows a plan view of a fifth embodiment of a security element according to the present invention.
  • Figure 6 shows a plan view of a sixth embodiment of a security element having matt non-reflective areas that also contain adhesive applied in such a way as to form designs and indicia;
  • Figure 7 shows a plan view of a seventh embodiment of a security element according to the present invention having demetallised regions to further enhance security
  • Figure 8 shows a plan view of an eighth embodiment of a security element according to the present invention having both demetallised regions and regions that will remain wholly transparent when embedded in a windowed substrate.
  • Figure 1 shows a security element 1 according to a first embodiment of the present invention for partially embedding into a fibrous substrate, such as a security paper or the like.
  • the security element 1 which is preferably made from metallised PET, is of varying width and may be of any desired length.
  • the security element 1 is substantially elongate in shape and has alternating wide portions 3 and narrow portions 4.
  • the element 1 is preferably symmetrical about a centre axis 5.
  • the extremities of the wide portions 3 are coated with a matt non-reflective coating 2 which is substantially the same colour as the substrate into which the element 1 is to be embedded. This leaves a constant strip which is uncoated along the centre of the element 1, which is the width of the narrow portions 4.
  • the security element 1 is partially embedded within the substrate, preferably using known papermaking or similar apparatus such as cylinder mould or Fourdrinier machines.
  • the process used is selected to produce a windowed substrate in which portions of the elements are exposed in windows at one or both surfaces of the substrate.
  • a method may be selected which enables a continuous strip of the element 1 to be exposed on one surface of the substrate, and portions exposed in windows in the other surface.
  • the narrow portions 4 of the element are typically less than 2mm in width.
  • the wide portion 3 is at least lmm wider than the narrow portion 4.
  • the security element 1 When embedded in a windowed substrate such as a security paper, the security element 1 will appear to be of a constant width in the windows when viewed in reflection. When viewed in transmission, the viewer will be able to see the overall shape of the element 1 including the coated parts of the wider portions 3 of the element 1 due to their increased opacity in contrast to the surrounding substrate.
  • Figure 2 shows an alternative embodiment of a security element 1 according to the present invention. In this ' embodiment, the security element 1 has been die cut such that the edges 6 are undulating. Security elements 1 with curved edges are harder to counterfeit and may also mirror a design applied to a security document or other article made from the substrate into which the security element 1 is embedded. Such a design may be created by demetallisation, diffractive effects or printed using inks.
  • the security element 1 When viewed in reflective light, the security element 1 will appear as a visible security element that has a width variation that is less then that of the whole element and may be designed so as to give the appearance- of a security of constant width. In transmissive light, the whole element 1 " will be seen.
  • FIG. 3 shows a further embodiment of the present invention.
  • the edges 6 of the security element 1 are castellated.
  • the wide portions 3 are only partially coated with the matt non-reflective coating 2 at their very extremities, leaving the majority of the wide portions ,3 and all of the narrow portions 4 uncoated.
  • the security element 1 When viewed in reflective light, the security element 1 will appear to be of constant width. In transmissive light, the whole element 1 will be seen.
  • Figure 4 shows how the current invention may be employed in respect of an element having a constant width. It has been found that, when embedding elements of widths greater than 2mm, problems can occur with poor fibre deposition along the edges 6 of the element. Again this can be unsightly and is certainly not desirable. The matt non-reflective coating is therefore used to mask this problem and is applied to the edges 6 of the security element 1. Although some of the width of the element is "lost" under the coating 2, the area of the Element under the coating 2 may be used for non-visual information such as magnetic coding as described in EP-A-0516790.
  • Figure 5 shows another embodiment of the present invention in which a security element 1 has a constant width.
  • a matt non-reflective coating 2 is .applied in a manner such that the uncoated section of the element 1 has undulating edges.
  • a security element 1 When such a security element 1 is embedded ,in a windowed substrate it will appear to have a varying width when viewed in reflection. However, in transmission, the entire shape of the security element 1 will be visible. This effect is both aesthetically pleasing arid results in a security element 1 that is harder to counterfeit than standard elements, particularly if elaborate patterns are used along either edge 6.
  • the coating 2 can be applied in patterns which contrast or complement demetallised, holographic or printed features on the security document or article or to provide visual continuity.
  • the security element 1 shown in Figure 6 has a matt non-reflective coating 2 applied in discrete regions within the body of the security element 1.
  • the matt non-reflective regions form both a design and alphanumerics . It will be appreciated by those skilled in the art that such an approach could be used in combination with matt coatings along the edges ⁇ or on wide portions as required. In reflection, only the uncoated portions of the security element 1 will be seen, whereas the whole security element 1 will be visible in transmission.
  • the matt coatings illustrated in Figure 6 are intended to be used when embedding elements according to W0-A- 00/39391 or similar methods where paper fibres are applied in discrete areas of an element but not necessarily extending across the element's full width. It has been found when trying to achieve these methods that poor deposition of paper fibres can lead to the element becoming exposed in areas that are intended to be embedded. It has been found that this problem can be overcome by adding a suitable adhesive to the matt non-reflective coating 2 prior to or after its ' application on to the security element prior to its inclusion into a substrate.
  • Figure 7 shows a further example of how the invention may be employed.
  • the matt non-reflective coatings are combined in register with demetallised regions 7, thus producing a visually striking effect and also an enhancement in the security of the final document, due to the added complexity of the security element.
  • the whole security element will only be visible in transmission.
  • Figure 8 shows yet another embodiment of the present invention. Areas 7 of a security element 1 which have a matt non-reflective coating 2 are also demetallised. In addition a second series of demetallised regions 8 are also shown. When the security element 1 is embedded into a substrate the series of demetallised non-reflective areas 7 will be covered by the substrate on one side and exposed in windows at the other side of the substrate. In contrast, the series of demetallised regions 8 form transparent apertures on which paper fibres are not deposited on either side of the paper. In transmission, the whole security element 1 will be visible, whereas the coated portions will not be visible in reflective light.
  • a matt non-reflective coating 2 may be applied in accordance with the present insertion on one side of the security element only and the other side of the security element may remain uncoated or may be provided with a full coating or, alternatively, a partial coating may be applied on both sides of the security element to prevent thread turnover (?) .
  • the security element 1 need not be symmetrical about the centre axis 5.
  • the security element to which the present invention refers may be in the form of a security thread or equally may be a plahchette.
  • the security element can be embedded in a security substrate used to make any security document, such as a banknote, Passport, voucher, passport, bond, certificate and the like.
