  • Patent number: 7939465
    Abstract: An image destruct material comprises a release layer positioned between an image receiving layer and a base layer. The adhesion between the release layer and the base layer is greater than adhesion between the release layer and the image receiving layer. The release layer material can be used in secure documents that have an image receiving layer. After information is printed on the image receiving layer, an overlaminate is applied over it. Removal of the overlaminate destroys the printed image on the receiving layer because of the relative adhesive properties of the image receiving layer, overlaminate and release layer.

  • Patent number: 7906201
    Abstract: The invention relates to a value document, in particular a bank note, having a value document substrate and different feature substances for checking the value document. According to the invention, a first feature substance is incorporated into the volume of the substrate of the value document, and second and third feature substances are applied to the value document substrate in a printing ink jointly and in the form of a coding. The second feature substance is formed by a luminescent substance, and the third feature substance by a material absorbent in a special spectral range. The two substances are used for the value recognition of different user groups.

  • Patent number: 7892639
    Abstract: Multi-layer, edge ingress, tamper- and solvent-indicating labels comprise a top film layer coated over a solvent, e.g., water, hydrocarbon, etc., and dye absorbing layer. The solvent and dye absorbing layer can be on top of a porous layer comprising a binder, pigment and particles of a solvent-soluble dye. The porous layer can be on top of an edge-wicking layer which itself is on top of a pressure-sensitive adhesive (PSA) layer. The edge-wicking layer both absorbs and transports solvent thus serving as a means for transporting solvent to the solvent-soluble dye.

  • Patent number: 7850063
    Abstract: A tamper evident envelope is disclosed which includes sealing strips located within the seams of the envelope. Each strip is formed by two clear plastic strips secured together. One of the clear plastic strips includes a groove and a dye located within the groove whereby the dye is sealed between the two clear plastic strips. When a seam is separated, the sealing strip is damaged thereby releasing the dye onto the adjacent portions of the envelope and providing visual evidence that the seam was opened. A second embodiment is disclosed where the dye is omitted and separation of the secured clear plastic strips results in damage to the envelope providing visual evidence of tampering.

  • Patent number: 7846520
    Abstract: A counterfeiting prevention label 1 has a label base 3 including a base sheet 31, and a volume hologram 2 including a volume hologram layer 22 and formed on the base sheet 31. The volume hologram 2 is extended between the upper side 31a and the lower side 31b of the label base 3. The opposite end surfaces of the volume hologram 2 are flush with the end surfaces of the label base 3, respectively. The volume hologram 2 may be placed in a depression 3a formed in the front surface of the label base 3. The volume hologram 2 and the label base 3 are blanked out after transferring the volume hologram 2 from a transfer sheet 10 to the label base 3.
