Definitions

  • This invention relates to security labels.
  • US 5,411,295 discloses a tamper-evident label in which water soluble indicia are applied over water insoluble indicia so that when exposed to water, the water soluble indicia are removed, revealing the water insoluble indicia.
  • a solution is unsuitable for protecting confidential information such as PIN numbers since the hidden confidential information can simply be revealed by exposing the label to water.
  • a security label 10 comprising a film layer 12 in the form of a polyester film.
  • a printable layer 14 is coated onto one side of the film layer 12 and a first ink layer 16 is printed onto the printable layer 14.
  • a second ink layer 18 is provided onto the opposite side of the film layer 12, and an adhesive layer 20 is provided on the second printed layer 18.
  • the first ink layer 16 is an organic solvent sensitive ink, which may be a u.v. curable solvent active ink such as manufactured by the company Luminescence Limited.
  • the first ink layer is a water sensitive ink, which may be a water fugitive ink formed of at least one water fugitive dye and inorganic/organic pigments in a varnish comprising a solution of hydrolised starch in glycerine.
  • the printable layer 14 comprises a 6 g/m 2 heat cured translucent polymeric crystalline lattice structure, which provides an overall matt effect and sufficient surface tension to allow laser toner to adhere thereto.
  • the first ink layer 16 is provided only around a portion of the printable layer 14, this portion being preferably in a rectangular configuration around an edge region of the label 10, as shown in Figs 4 to 6 . It will be appreciated that the first ink layer 16 could be applied to any desired region of the printable layer 14. Where the first ink layer 16 is a water sensitive ink it may be printed onto the printable layer 14 by lithographic, letterpress or flexographic printing and warm air cured.
  • the second ink layer 18 comprises a first region of a coloured filmic ink 22, namely a filmic pre-polymer ink which extends in a rectangular configuration around the edge region of the label 10 and corresponds in shape and size to the first ink layer 16.
  • a filmic pre-polymer ink which extends in a rectangular configuration around the edge region of the label 10 and corresponds in shape and size to the first ink layer 16.
  • the first ink layer 16 extends over the coloured filmic ink layer 22 thereby creating a colour which is a combination of the colour of the first ink layer 16 and the filmic ink 22.
  • the second ink layer 18 may be formed of a u.v. cured ink such as manufactured by the company Luminescence Limited.
  • the second ink layer 18 also defines a central region 24 comprising a printed filmic pre-polymer ink in the form of an obscurity pattern 26.
  • the label 10 is applied to a substrate, for example a sheet of paper 28 and is adhered thereto by the adhesive layer 20.
  • the adhesive layer 20 adheres the second layer ink 18 to the paper, and allows the polyester film 12 to be removed therefrom by peeling it away, as would be appreciated by the persons skilled in the art.
  • the purpose of peeling away the polyester film layer 12 from the second ink layer 18 is to allow printed matter 30 which is printed in a central region 32 of the first ink layer 16 to be read.
  • the central region 32 corresponds in shape and size to the obscurity pattern 26 of the second ink layer 18.
  • the printed matter 30 can only be read if the polyester film layer 12 is removed from the second ink layer 18, which is easily done by peeling the polyester film layer 12 from the second ink layer 18 when the label has been adhered to the paper 28.
  • the first ink layer 16 comprises a water fugitive ink
  • the first ink layer 16 reacts to liquids 34 comprising water.
  • the contact of water with the first ink layer 16 causes reticulation and pigment dispersal or migration to the edges of the moisture contact region. This renders the central area of the contact region devoid of pigment or "clear". This allows the second ink layer 18 below to be visible in the bleached regions 16A, thus alerting the user to the fact that tampering has occurred.
  • the colour of the first ink layer 16 can be, for example, blue, and the colour of the outer coloured filmic ink 22 could be, for example, red. With this combination of inks, the colour which is seen by the user is a purple. As the liquid 34 migrates outwardly across the region 32, the bleach region 16A become larger and more obviously visible. Since the bleached region 16A are regions in which the ink of the first ink layer 60 has been removed, the colour that is seen by the user is the colour of the colour filmic ink 22, i.e. in the present case red.
  • Fig 7 there is shown the label 10 applied to a carrier in the form of a sheet of release paper 38, which carries a plurality of the labels 10 comprising of them being applied to a sheet of paper 28.
  • a security label 10 which has the advantage of providing a tamper evident label to detect attempted fraudulent activities in attempting to find out the information on printed matter 30 printed on the region 32 of the label 10.
  • the shape and size of the outer regions carrying the first ink layer 16 and the filmic colour ink layer 22 could be of any design, shape and size.
