A process for preparing identification cards which comprises spreading bonding material on a substrate, placing a transparent film over the coated substrate, superposing a photograph having opaque and transparent portions, directing light rays to harden portions of the bonding material which correspond to the transparent parts of the photograph, spreading particulate material over the bonding material, removing the particulate material that has not adhered to the bonding material, and sealing a transparent covering. An identification card comprising a thermoplastic coated magnetic backing means, large number of individual particles arranged to constitute a photographic image bonded to the thermoplastic coated backing means, and a transparent covering overlying the backing and heat sealed thereto. Also provided is a unitary laminated identification card that has a three-dimensional effect which cannot be readily photographically counterfeited and is substantially tamper-proof.
A process, utilizing the following raw materials (a) backing means having a heat-sealable surface, (b) a bonding material that is photosensitive and becomes harder upon exposure to light, and (c) a transparent heat-sealable cover, said surface, said bonding material and said cover being compatible in that they may be merged and caused to flow together to form one integral construction when adequate heat and pressure are applied to them, for producing identification cards, comprising:
The process of claim 14 wherein said particulate material includes mildly radioactive isotopes and/or radioactive rare earth metals or compounds thereof.
A process, utilizing the following raw materials (a) a backing having a heat-sealable surface, (b) a material that is tacky and is photosensitive and becomes harder and non-tacky upon exposure to light, and (c) a transparent heat-sealable cover, said surface, said material and said cover being compatible in that they may be merged and caused to flow together to form one integral construction when adequate heat and pressure are applied to them, for producing an identification card which comprises spreading said material on a substrate to form a coated substrate, placing a transparent protective film over the coated substrate, superposing on the transparent protective film a half-tone photograph having an opaque portion and a transparent portion, exposing said coated substrate to light rays by directing light rays through the photograph to render non-tacky the portions of said material which correspond to those parts of the photograph that are transparent, removing the photograph and the protective film from said coated substrate, spreading particulate material over said first-named material so that the particles stick to the tacky portion of the first-named material, removing the particulate material that did not adhere, placing said coated substrate in contact with said surface of said backing in such a manner so that said first-named material is directly contacting the backing and transfers said tacky portion of the first-named material and the particulate material on said tacky portion to the backing, and removing the coated substrate from said backing whereby the tacky portion of said first-named material remains adhered to said backing, placing said transparent heat-sealable cover over said surface including any of said materials that have adhered to said surface, and applying heat and pressure to the surface, the materials and the transparent cover, to merge them together causing said first-named material to merge into said surface and causing the transparent cover to merge into said surface including such merger in the spaces between half-tone dots, thus to form an identification card in which the backing, the first-named material and said cover have become integral thus improving the alter-proof characteristics of the card.
A process for producing an identification card which comprises spreading bonding material that is hardened by light on a substrate, placing a transparent protective film over the coated substrate, superposing on the transparent protective film a half-tone photograph having an opaque portion and a transparent portion, exposing said coated substrate to light rays by directing light rays through the photograph to harden the portions of the bonding material which correspond to those parts of the photograph that are transparent, removing the photographic image and the protective film from said coated substrate, spreading particulate material over said bonding material so that the particles stick to the unhardened portion of the bonding material, removing the particulate material that has not adhered, and thereby obtaining the photographic image, providing a backing and a transparent cover which are compatible with each other and with said bonding material in the sense that they merge together under heat and pressure, placing said coated substrate with said image thereon in contact with a backing in such a manner so that the image is directly contacting the backing, removing the coated substrate from said backing whereby the image remains adhered to the backing, and sealing a transparent covering to the backing by heat and pressure to join the backing and the covering not only between the dots of particulate material but outside the boundary of the picture formed on the backing.
