A security device for authenticating bank notes, documents and other items, comprises a luminescent material for producing luminescent radiation of first and second wavelengths. The security device includes an optically variable structure for controlling emission of luminescent radiation of at least one of the first and second wavelengths from the security device, the security device being arranged to permit, from an area of the optically variable structure, emission of luminescence of the first and second wavelengths from the security device. The optically variable structure causes the relative emissivity of the security device for luminescent radiation of the first and second wavelengths to change with a change in emission angle, so that the security device produces an angle-dependent color shift in the emitted luminescent radiation. The optically variable structure may comprise an optical interference stack that controls transmission of luminescent radiation therethrough in response to the wavelength of luminescent radiation.

A security paper for manufacturing value documents has a planar substrate equipped on one surface with an anti-forgery means based on a carrier foil having an optically variable security feature. The anti-forgery means and a partial substrate area surrounding the anti-forgery means is furnished with a dirt-repellent radiation-curing first lacquer substantially not influencing the perceptibility of the optically variable security feature. The layer thickness of the lacquer lying is in a range of 0.7 to 2 micrometers. The radiation-curing first lacquer is may be a UV-cross-linking lacquer which after cross-linking is high-gloss. The substrate can be furnished on its surface lying outside the anti-forgery means with a dirt-repellent second lacquer and optionally partly overlaps the first lacquer in the region of the partial substrate area surrounding the anti-forgery means. The second lacquer involves either a physically drying, water-based dispersion lacquer, or a UV-cross-linking lacquer, and has a matt impression.

56 FORENSIC FEATURE FOR SECURE DOCUMENTS US11460207 2006-07-26 US20070102920A1 2007-05-10 Daoshen Bi; Tung-Feng Yeh; Robert Jones; J. Carr
A forensic feature for a secure document comprises a base document layer and a covert material applied to the base document layer. The covert material includes a carrier and forensic material within the carrier. The forensic material includes a ratio of salts or oxides of metals, such as rare earth metals. The ratio is selected to correspond with a source of the document. The forensic material may be mixed into a coating or ink that is applied at predetermined locations on a secure document. The ratio is then measurable from metal ion signals of the salts or oxides. This ratio, or some metric derived from it, may be linked with information embedded elsewhere in the document to enable verification of the document. Another forensic document feature has a forensic metric that is measurable from a covert material in the document, and this forensic metric corresponds to a source of the document. A blocking layer applied over the covert material prevents access to the covert material such that at least partial destruction of the document is required to measure the forensic metric. The blocking layer may have a blocking property that blocks electromagnetic waves from activating the covert material, or blocks the electromagnetic waves from the covert material in response to the activating waves. The blocking layer is deconstructed to access the forensic feature, verify the document and perform forensic tracking.

59 Method of producing an optical or magneto-optical recording card and transfer type optical or magneto-optical recording medium US397609 1989-08-23 US5156941A 1992-10-20 Minoru Fujita; Yoichi Fukushima; Toshio Haga
An optical or magneto-optical recording card is produced using a transfer type optical or magneto-optical recording medium. The transfer type optical or magneto-optical recording medium comprises a base film, a peeling layer, an optical or magneto-optical recording layer and a light permeable adhesive layer which are successively superimposed one above another to constitute a layered structure. A protective layer is adhered to the transfer type optical or magneto-optical recording medium with the aid of an adhesive layer and the base film is then peeled off together with the peeling layer. Next, the protective layer to which the optical or magneto-optical recording layer is adhered is adhesively attached to a card base in such a manner that the optical or magneto-optical recording layer is interposed therebetween whereby an optical or magneto-optical recording card is completely produced. The transfer type recording medium can be preserved in such a state that it is wound about a reel. Accordingly, the transfer type recording medium is adhered to the protective layer when the optical or magneto-optical recording card is produced, and thereafter it is adhered to the card base. Thus, the optical or magneto-optical recording card can be produced at a high productive efficiency.
60 Method of producing an optical recording card having a hologram contained therein US338713 1989-04-14 US5010243A 1991-04-23 Yoichi Fukushima; Minoru Fujita; Yuji Kakinuma; Toshio Haga
A certification card such as ID card or the like includes a hologram and an optical recording portion. Hologram is such that an amplitude and a phase of a light wave emitted from an object are recorded and an image of the object is rebuilt by emitting light to reproduce of an amplitude and a phase of the thus emmited light. An optical recording technique for use with the card employs data pits which are formed on an optical reflective surface of an optical recording layer. The thus formed data pits are detected by difference in optical reflectivity from the data pits when the object is illuminated by laser beam so that data are read. The card is constituted by adhering a card front substrate to a card rear substrate, and hologram and optical recording portion are formed between the card front substrate and the card rear substrate. The certification card is difficult to falsify and alter and, therefore, has high safety.
