Definitions

  • the present invention is directed towards a security document comprising a security sheet formed from a plastic substrate and an adjacent page of fibrous substrate.
  • the present invention is further directed to a plurality of such security documents and a method of manufacturing the security document.
  • the present disclosure is yet further directed to a security thread, a security sheet comprising the security thread and a method of manufacturing the security sheet.
  • Security documents and booklets such as passports, passbooks, identification documents, certificates, licences, cheque books and the like, commonly comprise one or more security pages on which information is provided.
  • a passport booklet typically comprises a cover and a plurality of internal visa pages therebetween.
  • the visa pages are made from paper having a grammage of around 85 gsm and are sewn together along a stitch line. The cover is adhered to the outside of the visa pages and thereby protects the stitch line.
  • At least one security sheet or data page is provided in the booklet and is usually the second or the penultimate page, typically located between one of the visa pages and the cover.
  • the security sheet usually contains personal data and is generally overlaid by a layer of polymer laminate, usually applied as a film or lacquer. This layer helps protect the data and prevent counterfeiting and fraudulent alteration.
  • the security sheet may be formed from a fibrous substrate and may comprise security features, such as watermarks, laser perforations, security fibres, security threads, security print and the like.
  • the security sheet may be formed from a sheet comprising a plastic, which is typically polycarbonate.
  • Plastic sheets are more durable than fibrous substrate security sheets and are resistant to delamination by a counterfeiter.
  • a number of thin plastic layers are laid over one another and fused together, thereby forming a thicker plastic sheet.
  • the most common method of fusing the thinner plastic layers together involves placing them in between a "sandwich" of steel or brass laminating plates. A number of such sandwiches are stacked on top of each other and heat is applied to the top and bottom of the stack. The heat is transferred through the thinner plastic layers and laminating plates such that the thinner plastic layers fuse together, thereby forming a plastic sheet within each sandwich.
  • a low temperature is then applied to the top and bottom of the stack to cool and harden the plastic sheets.
  • such a method is relatively time inefficient as each heating and cooling cycle lasts for around thirty minutes.
  • a plastic security sheet may comprise various security features, such as UV responsive arrangements, optically variable features, windowed or transparent features, laser-perforations, laser markings and tactile features.
  • EP-B-261 1622 discloses the introduction of a security thread in between the plastic layers before they are laminated together.
  • US-A-2014/0138444 discloses a data carrier card in which a security thread is coextruded in the form of a thread strip in one of the plastic layers before they are laminated together.

  • the first and second patterns are substantially identical.
  • the first and second patterns combine to form a third pattern visible when the security sheet and adjacent page overlie one another in the at least one window when the security sheet is viewed in reflected light, the third pattern being different to the first and second patterns.
  • the second security device overlies the first security device when the security sheet and adjacent page overlie one another, the second security device being at least partially transparent such that the at least one exposed region of the first security device is visible through the second security device.
  • the second security device is preferably arranged to adjust the visible image of the first security device when viewed through the at least one window.

  • the first security device comprises a first security thread and the adjacent page is formed by a process comprising: depositing fibres on to a support surface to form a layer of the fibrous substrate; contacting the first security thread with raised regions and/or drainage restriction regions of the support surface to partially embed the first security thread in the fibrous substrate and form the at least one exposed region; couching the fibrous substrate layer and first security thread from the support surface; and drying the layer of fibrous substrate.
  • the plurality of plastic layers comprises a substantially transparent insert for forming the window.
  • the insert preferably comprises the second security device.
  • the second security device is preferably incorporated into, or located between, one or more of the plurality of plastic layers. Alternatively, the second security device may be applied to at least one outer surface of the plastic substrate.

  • “Registration” may be considered to mean that the first and second security devices 75, 76 combine co-operate to form a visible security effect when viewed together, preferably in reflected visible light, which is not visible when the first and second security device 75, 76 are each viewed alone.
  • the visible security effect forms an easily detectable and recognisable pattern for ease of authentication.
