| Polymer fibers are formed with concentric alternating layers of different polymer materials. The layers pairs have cross-sectional thicknesses selected for reflecting light at a selected visible wavelength. A cross-sectional dimension of the core is at least ten times an average of the selected thicknesses of the alternating layers. Some articles formed by the fibers are formed by attaching one fiber to another: the color of the fibers at the point of attachment is different from the colors of the fibers elsewhere. The fibers may be deformed to change its color properties by elongating the cross-section of the polymer fiber along a first cross-sectional axis. In some embodiments, the fibers are polarization sensitive. | ||||||

| 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 colour 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. | ||||||

| 192 | Method of producing an optical or magneto-optical recording card and transfer type optical or magneto-optical recording medium | US471037 | 1990-01-26 | US5110707A | 1992-05-05 | Minoru Fujita; Yoichi Fukushima; Toshio Haga |
| An optical recording card is produced using a transfer type optical recording medium. The transfer type optical recording medium comprises a base film, a peeling layer, an 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 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 recording layer is adhered is adhesively attached to a card base in such a manner that the optical recording layer is interposed therebetween whereby an 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 recording card is produced, and thereafter it is adhered to the card base. Thus, the optical recording card can be produced at a high productive efficiency. | ||||||
| 193 | Optical recording card having hologram contained therein and method of producing the same | US108473 | 1987-10-14 | US4945215A | 1990-07-31 | Yoichi Fukushima; Minoru Fujita; Yuji Kakinuma; Toshio Haga |
| The present invention is concerned with a certification card such as ID card or the like including hologram and an optical recording portion.Hologram is such that an amplitude and a phase of 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 emitted light.On the other hand, optical recording technique is such that data pits are formed on an optical reflective surface of an optical recording layer and the thus formed data pits are detected by difference in optical reflectivity from the data pits when the object is lightened by laser beam so that data are read.According to the present invention a card is constituted by adhering a card front board to a card rear board, and hologram and optical recording portion are formed between the card front board and the card rear board.The such prepared certification card is difficult to be falsified and altered and therefore it has high safety. | ||||||

| 195 | Method for forming data cards with registered images | US31714 | 1987-03-27 | US4818852A | 1989-04-04 | Richard Haddock; Joseph B. Arnold; Jerome Drexler |
| Data cards are formed by writing a succession of latent images on a first web of photosensitive film, developing the film and then joining the film with a web of high resolution laser optical recording tape. The webs may be joined in either back-to-back or front-to-back relationship. In the first case there is an eye readable image on one side and formatted optical recording tape on the opposite side. In the second case an eye readable image is optionally adjacent optical recording tape, but on different layers, with both readable from the same side through a transparent substrate or base. The composite web is cut transversely to its lengthwise dimension into a plurality of wallet size members. Bar code is recorded together with the latent image so that in checking cards for quality control purposes, defective cards may be correlated with particular images in order that a defective card be recreated. The high resolution optical recording tape is preformatted with continuous servo tracks or data location grids without header information so that registration of the eye readable images and the laser recording tape is not necessary. | ||||||

| 197 | Method for making an identification card having features for testing in incident and transmitted light | US809854 | 1985-12-18 | US4711690A | 1987-12-08 | Yahya Haghiri-Tehrani |
| The multilayer identification card comprises several synthetic layers compounded by the effects of heat and pressure. An inside interface of at least one of these layers exhibits depressions which are filled with the material of the adjacent layer during the laminating process. The adjacent layers are selected in such a way that they are of different transparency. Thus a light and shadow effect is produced in incident light which is reversed in transmitted light. | ||||||

| 200 | Document having light-transmissive, electrically conductive authenticating interior layer | US565452 | 1983-12-27 | US4591189A | 1986-05-27 | Reynold E. Holmen; Edward J. Downing |
| A standardized document such as a credit card has a thin, light-transmissive, electrically conductive interior layer, the impedance, capacitance, or conductance of which can be sensed to indicate the authenticity of the document. When the document is cut to expose a new edge, the authenticating layer at that edge is not visible to the naked eye and hence should foil the ordinary counterfeiter. | ||||||
