The invention comprises a security substrate for making security documents and the like comprising a fibrous base substrate and an elongate security element at least partially embedded therein. At one surface of the security substrate one portion of the security element is exposed to provide a continuous track along the length of the security element. A plurality of other portions along at least one edge of the security element are partially covered by overlapping regions of the fibrous substrate. The invention further comprises a method of manufacturing such a security substrate.

  • Patent number: 8257840
    Abstract: The present invention provides a security functional thin film and a security product containing such a thin film. The security functional thin film is of an amorphous structure, and possesses soft magnetic characteristics. Large Barkhausen effect can be detected along the in-plane preferred direction of magnetization; and the Large Barkhausen effect significantly attenuates, or no such signal can be detected, in a direction perpendicular to the in-plane preferred direction of magnetization. The thin film has a thickness of 20-300 nm, and the thin film also possesses element encoding characteristics that can be authenticated by experts. The security functional thin film of the present invention can be fabricated by magnetron sputtering web coating process.

  • Patent number: 8221586
    Abstract: The invention relates to improvements in security substrates and in particular to fibrous security substrates, such as paper, incorporating a watermark. The security substrate comprises a fibrous base layer, having a normal base fiber density, said base layer incorporating a watermark consisting of a plurality of alphanumeric characters. Each character comprises dark and/or light regions, the dark regions being formed by more densely deposited fibers than the normal base fiber density and the light regions being formed by less densely deposited fibers than the normal base fiber density. The density of the fibers in any region is substantially uniform such that there is no gradual change of tone between the light and dark regions. Each dark and light region adjoins at least one light and dark region respectively and an area of normal fiber density.

  • Patent number: 8118975
    Abstract: This invention relates to papers made with fibrids containing a polymer or copolymer derived from a monomer selected from the group consisting of 4,4?diaminodiphenyl sulfone, 3,3?diaminodiphenyl sulfone, and mixtures thereof. Such papers have high thermal stability and accept ink more readily than papers made solely with aramid fibrids.
