  • Publication number: 20120104743
    Abstract: A document which may be a security document has a thermochromic coating which may be a thermochromic ink on the substrate of the document. The ink may include several thermochromic materials which transition from various different colors to substantially clear in appearance as the ink is warmed to various temperatures. The combination of the colors of the thermochromic materials can give the document a different color at a number of different temperatures, until the coating is warmed to the highest color change point. When at or above the highest color change temperature, the coating becomes substantially transparent and the printed area assumes the color of the underlying substrate. The coating may also include non-reactive materials of yet another color that mixes with the colors of the thermochromic materials.

  • Patent number: 6543808
    Abstract: An improved construction for pull-tab game pieces involves the use or two or more substrates, one of which is at least partially transparent. A thermosensitive imaging layer within which game results are direct thermally printed is located between the transparent substrate and an opaque cover layer through which the game results are printed. An opaque substrate precut to form one or more tabs covers the opposite side of the transparent substrate. The game results are revealed by retracting the tabs to view the game results through the transparent substrate.

  • Publication number: 20020090556
    Abstract: The invention relates to improvements in security features in paper and other substrates and in particular to an activatable feature to warn of tampering. The invention further relates to a security feature for a security document comprising at least one activatable layer and at least one visually apparent masking layer, said at least one activatable layer comprising a composition which is generally non-mobile but which becomes mobile when wetted with a liquid, said composition further including at least one detectable component, in which under dry conditions said at least one masking layer wholly covers the activatable layer and renders it non-detectable.

  • Patent number: 6406062
    Abstract: A hidden image game piece and a method by which a hidden image game piece is produced and used. A first hidden image game piece is formed on a transparent or translucent substrate. A second hidden image game piece is formed electronically, and optionally printed or, alternatively, saved and distributed in electronic format. The hidden image game piece can be used to distributed either physically or electronically, and it may be used to derive demographic information from recipients, to drive them to web sites or retail outlets, and to provide a means for distributing advertising, either on the game pieces or at a game site, which may be a physical site, such as a retail outlet, or an electronic site, such as an Internet site. The methods of the present invention include the method of producing a game piece, the method of deriving demographic information from recipients of the game pieces, and the method of providing advertising to recipients of the game pieces.

  • Patent number: 6328342
    Abstract: A tape data carrier for protecting articles and documents from counterfeiting and copying is formed by a polymer structure including at least one polymer layer of which at least one layer has at least one of through-perforations and pits. These through-perforations and pits are preferably between 0.001 &mgr;m and 20 &mgr;m in size and can be filled with different materials. The data carriers can carry concealed and visible macro-and micro- images created by heavy-ion bombardment of the polymer film, subsequent exposure of the bombarded film to ultraviolet radiation, and etching of the polymer film in a solvent. A device for manufacturing a data carrier of this type includes the following elements configured in series: a heavy ion source; a heavy ion beam-formation system; an ion guide; a three-dimensional amplitude modulation unit; and a target which is destined to become the data carrier.

  • Patent number: 6318760
    Abstract: A metal layer cleared by contact with a chemical clearing agent to reveal an underlying graphics layer is at least partially covered by a buffer material that delays contact with the clearing agent. The buffer material can be applied in a pattern that forms a temporary image in the metal layer prior to more completely revealing the underlying graphics layer.

  • Patent number: 6261809
    Abstract: The invention relates to a method for marking solid, liquid or gaseous substances, whereby the substance to be marked is provided with at least one synthetically produced nucleic acid sequence. Said nucleic acid sequence contains a first sequence section constructed with the 5′ terminal end, a second sequence comprised of at least two bases and connected to said nucleic acid sequence, and a third sequence section constructed with the 3′ terminal end and connected to the said nucleic acid sequence. In order to simplify the identification of the marking, the invention provides that a first primer group is used with a first primer section corresponding to the first sequence section and a second primer group is used with a third primer section corresponding to the third sequence section.

  • Patent number: 6224111
    Abstract: Unauthorized alteration of a document can be avoided in a secure document that includes a substrate (10) defining the body of the document. Indicia (24, 26, 30, 32, 36 and 40) located on the substrate (10) designate an area (42) to receive variable information by an impression. The variable information is that whose alteration is to be avoided. A chemical, carbonless imaging system (44) is disposed on the substrate (10) at the area (42) and is operative to form a visible image upon receipt of an impression and a transparent film (46) is located on the substrate (10) to cover the area (42). As a consequence of the construction, any attempt to alter an image appearing on the film (46) will be apparent from the original imaging of the chemical carbonless imaging system (44) or by smudging thereof indicating an alteration attempt.

  • Patent number: 6095568
    Abstract: The invention relates to a device for sealing pressure compensation openings in components in particular of a motor vehicle control unit. Previously, pressure compensation openings were sealed in the interior of the housing by a watertight and gas-permeable material affixed by adhesion. In accordance with the invention, the opening is sealed from the outside with a two-layered material where a wide-area first layer consists of a material that can be inscribed and a second layer, which can also be provided over just a part of the total area, is a watertight and gas-permeable membrane. At those places where pressure compensation occurs, the first layer is removed so that only the membrane acts. The first layer can be used here as a label. Advantages offered by this device are that the housing and the membrane are joined over a much larger area, the process can be monitored, and one process step is saved.

  • Patent number: 6073968
    Abstract: A business document contains a removable decal. The decal has a plastic substrate overlaid with a reflective coating including an aluminum coating and glass beads. A toner receptor coating overlies the reflective coating. A fine screen pattern is printed on the toner coating and which pattern may include jagged lines or closely spaced dots. Variable and non-variable information is then printed on the toner receptive coating. In the event of use of a solvent to alter the printed information on the decal, the fine printed screen pattern is likewise disrupted and evidences alteration of the decal.
