  • Patent number: 6358596
    Abstract: A cellulosic sheet suitable for use as a security document is provided including a multi-functional transparent secure mark formed therein. In accordance with one embodiment of the present invention the secure mark comprises a transparentized portion of the substrate. The cellulosic substrate defines first and second major faces. The transparentized portion comprises a transparentizing composition applied to the cellulosic substrate in a predetermined pattern so as to define a graphical image having a relative transparency selected so as to define an area of increased transparency in the substrate. The transparentizing composition comprises a transparentizing agent and a security agent. In one embodiment of the present invention, the transparentized portion includes a printed portion and printed matter defining the printed portion is covered by the transparentizing composition.

  • Patent number: 6258746
    Abstract: A thermally imagable business record, such as a form, label, tag, or the like is provided which may be activated to form human and/or machine readable images as well as different colored images. The record comprises a substrate having a thermally imagable coating on substantially its entire surface which forms a first color when activated, and having a desensitized area on at least one area of its surface which may be overcoated with a thermally imagable coating capable of forming a different color upon activation than the first thermally imagable coating. The first thermally imagable coating provides images which are of machine readable quality, while the additional thermally imagable coatings provide images of a different color to designate selected areas on the form or label to a user.

  • Patent number: 6143120
    Abstract: A cellulosic substrate which is suitable for use as a mailer or envelope and which has at least one transparentized portion is provided. A method of transparentizing a cellulosic substrate by the application of a transparentizing material which provides enhanced toner adhesion properties, fast penetration rates and which is cured by exposure to radiation is also provided. The addition of small amounts of water to the transparentizing material enhances penetration rates. Further, these transparentizing materials may be applied without the need for solvents. These features thus permit continuous, in-line transparentization.

  • Patent number: 6139065
    Abstract: Security paper, security documents made from the security paper, and processes for making the security paper, are provided. A filament is bonded and embedded into paper which has previously been manufactured. The filament is bonded to the paper by an adhesive, or by heat and pressure. The filament is embedded into the paper by pressure applied by rolls. The filament may be imprinted with printed matter for visual confirmation of document authenticity. The filament may include any combination of security features, such as reflective filaments, fluorescent filaments, and high tensile strength filaments.

  • Patent number: 6073377
    Abstract: An over-wrap label for a container includes a label substrate having a first end and a second end, a first major surface and a second major surface. The first major surface includes a first area of adhesive material adapted to secure the first end of the label substrate to the container, a second area of adhesive material adjacent to the second end of the label substrate, and at least one portion of the first major surface remains free of adhesive. The second major surface includes an area of release material, the label being of a size such that the second end of the label substrate extends around the container and overlaps the first end. The second end is releasably securable to the second major surface of the label substrate by contacting the second area of adhesive material with the area of release material.

  • Patent number: 6031020
    Abstract: The present invention is directed to the deliberate cancellation of MICR-readable documents by applying a penetrating ink through the MICR line of the document wherein the ink contains magnetic particles which disrupt the reading of the MICR line by the MICR reader. The magnetic particles in the ink do not penetrate along with the other ink components, but remain on or near the surface of the document. These extraneous magnetic particles interfere with MICR readers by preventing accurate reading of the encoded MICR characters and cause the MICR reader to reject such a document from normal processing automatically.

  • Patent number: 5984363
    Abstract: A thermally imagable business record such as a form, tag, label or the like is provided in which selected areas of the record may be activated to form an image upon exposure to heat. In one embodiment, at least one selected area of a substrate surface contains a thermally imagable coating of initially colorless color formers and color developers while the remaining areas of the substrate are left uncoated. The substrate may be pre-coated to provide a smooth, non-porous base coat for the thermally imagable coating, and may also include a protective coating layer to protect the subsequently printed thermal image.

  • Patent number: 5944881
    Abstract: A security ink is provided containing a colored dye, a colored pigment, and a fluorescent pigment. The ink may be printed on a number of security documents such as checks and may be passed through printing devices such as laser printers without the problem of damage to the ink the printed image, or the printer. The fluorescent pigment in the ink will fluoresce when the document is exposed to ultraviolet light and may be used to provide an authentication feature.

  • Patent number: 5912205
    Abstract: A security document is provided containing a color-forming composition having an insulating material therein which allows the document to be passed through heated printing devices such as laser printers without the problem of premature color development. The color-forming composition includes a mixture of a color former, a color developer, and an insulating material. In a preferred embodiment, a toner adhesion-enhancing composition containing an insulating material is applied over the color-forming composition. The security document may be used to provide an authentication feature and/or an indication of attempted alterations from the use of solvents, heat or abrasion.

  • Patent number: 5888283
    Abstract: A direct thermal ink composition is provided which is formed from an aqueous dispersion of an initially colorless color former and an initially colorless color developer in particulate form. The direct thermal ink composition also includes a sensitizer, where the particles of the sensitizer at least partially surround the particles of the color developer, which prevents premature color development of the ink. The thermal ink preferably has a solids content of between about 40 to 60% by weight, and is substantially free of pigments and fillers.
