Abstract: A high-security identification card produced by thermal printing personalized data on a transparent image receiver sheet and laminating the image-bearing surface of the receiver sheet to an opaque card support optionally bearing background printing. During thermal printing of the personalized data, the receiver sheet is supported by a carrier sheet adhered to one side thereof. The carrier sheet is removed prior to lamination by mildly fusing the personalized data bearing surface of the receiver sheet to the pre-printed background information bearing surface of the identification card and mechanically flexing the sandwiched structure to cause the relatively inflexible carrier sheet to break free, at least in part, from the receiver sheet to enable its removal. After removal of the carrier sheet, the sandwiched structure is laminated by heat and pressure applied thereto to cause it to fuse permanently.

Abstract: An improved specialty ticket of the paper type having a first panel with visible indicia on a portion thereof to identify the ticket and a second panel formed with folded sections concealing indicia that represents winning or non-winning combinations thereon. The perforations extend along and through the side edges of at least the folded sections to hold the folded sections securely together while allowing the folded sections to be easily separated for viewing the combination of indicia on the second panel. Opaque colors such as dark black or dark blue are placed on at least one side of at least one of the foldable sections to prevent viewing of the concealed indicia when the sections are folded.

Abstract: A display has a transparent plastic substrate and a colored image formed on the substrate. The colored image is formed on the substrate by process printing a large number of small dots, colored red, yellow, and blue, in a predetermined pattern onto the substrate. The red, yellow, and blue ink dots are translucent to visible light. A reflective layer is deposited against the ink layer to reflect light which passes through the ink layer and thereby give the image formed by the ink layer a shiny, metallic appearance. A stratum of opaque white ink is deposited between the reflective layer and preselected portions of the image to block the passage of visible light from the preselected portions to the reflective layer.

Abstract: A process for preparing a confidential postcard contains dehydrating a starting paper material containing 25 to 45% by weight of fibers of a thermoplastic resin and 55 to 75% by weight of fibers of a natural plant to thereby form a paper layer, heating, during or after drying, the paper layer at a temperature not lower than a softening point of the thermoplastic resin fibers to thereby obtain a paper sheet in which the fibers of the thermoplastic resin retain fiber shape and are entangled with the fibers of the natural plant, inscribing a statement to be kept confidential on the paper sheet, superposing the paper sheet to conceal the statement and attaching provisionally the superposed paper sheet by heating under pressure at a temperature not lower than a softening point of the thermoplastic resin fibers to obtain the confidential postcard. The confidential postcard is capable of being peeled off with the statement on the paper sheet being left intact.

Abstract: A sealed card comprises a card substrate and a cover sheet disposed over the surface of the card substrate for sealing the substrate, wherein a transparent resin film having a thin transferable membrane with a hiding power releasably deposited thereon is put between the card substrate and the cover sheet by a transparent pressure sensitive adhesive layer and another pressure sensitive adhesive layer, respectively. The card surface is usually covered and concealed by the cover sheet and the thin transferable membrane and can be read through the transparent resin film by easily peeling the cover sheet together with the thin transferable member from the surface of the resin film. The sealed card can be manufactured easily.

Abstract: A self-assembled personalized message device including a base substrate with one or more blank areas on which messages can be written; a transparent cover sheet for covering the message areas, a material for adhering the cover sheet to the substrate, and a removable, opaque coating on the cover sheet for obscuring the message area when the cover sheet is adhered to the substrate in which the opaque material is capable of being rubbed off the cover sheet to selectively reveal the message written in the message areas.

Abstract: An identification card comprises a center core layer, a photograph embedded in the core layer, a first assembly of multiple layers laminated on the upper surface of the core layer and the photograph, and a second assembly of multiple layers laminated on the back surface of the core layer and the photograph. The layers of the first and second assemblies have substantially similar thermal expansion properties. Accordingly, the thickness of the identification card is uniform since the thickness of the core layer is substantially the same as the thickness of the photograph. High reliability can be obtained without any accompanying warp as a result of the substantially symmetrical arrangement of the first and second assemblies with respect to the core layer and the embedded photograph.

Abstract: Label assemblies for redeemable coupons, pressure-sensitive labels, lottery tickets and the like. A strip of redeemable coupons comprises an indefinite length web coated with a release coating, at least one coupon on the web comprising a sheet of stock material, a first dry coating layer covering the surface of the stock material, a second dry coating covering the first dry coating and a pressure-sensitive adhesive layer over the second dry coating and adhesively securing the coupons to the web. The first and second dry coating layers are substantially incompatible so that they separate from one another when the coupon, applied to an uncoated surface, is pulled therefrom.

Abstract: A postal card having a cover sheet releasably bonded to the printed surface of a card substrate, comprising a card substrate on which secret contents are printed, a transparent protection film made of a thermoplastic resin bonded by means of adhesive layer to the printed surface of the card substrate, a cover sheet applied with a lamination film made of a thermoplastic resin different from the thermoplastic resin for the protection film, and a coupling layer made of the same kind of the thermoplastic resin as that for the lamination film and supplied between the protection film and the lamination film while heated to a temperature within a range from the softening point to the melting point of the resin for releasably coupling the protection film and the lamination film, in which the protection film, the coupling layer and the lamination film are firmly secured with each other at a fixing area and a releasing area is formed at another portion of the outer peripheral region.

Abstract: In an identification card to be read by a magnetic system, having two protective plates between which a plate-like data carrier is held and protected, this data carrier being made of a material acting upon a magnetic field and having zones providing the data and acting variously upon the magnetic field, it is proposed, in order to lengthen the life of the card as well as to provide greater security against counterfeiting, that the two protective plates be made from non-magnetizable metal, preferably sheet bronze, and that the data carrier be embedded between the two protective plates in a layer of adhesive, plastic or solder, the two protective plates being thereby firmly joined together.

Abstract: A security token, such as a bank note or identity card, comprises a sheet-like substrate made up from film of transparent bi-axially oriented polymer coated with layers of opaque and heat activated adhesive material. The opaque layer is applied in such a way as to leave a transparent area for inspection of a security device, for example, a diffraction grating, incorporated in the polymer film. The substrate may bear printed or other identifying indicia and is protected with an intimately bonded layer of transparent polymeric material.

Abstract: A card is disclosed which is made of a thermoplastic material and having visually recognizable, internal safety markings. The card comprises a first sheet of a transparent thermoplastic material and a second sheet of an opaque thermoplastic material. The second sheet has an inner surface provided with a relief structure such that the varying thickness of the opaque material will influence the local absorption of transmitted light. The first sheet has an inner surface provided with a corresponding negative relief structure. The first and second sheets are laminated together with their inner faces in contact to form an interface. Thus, when viewing the card in transmitted light, the relief structure is visually recognizable as a varying brightness due to varying absorption of the light transmitted through the opaque sheet.

Abstract: A multilayer identification card bearing information such as letters, numbers, patterns, pictures and so on, in which at least part of the information is present in the form of a structure in relief in a foamable synthetic material. The foamable synthetic material is transparent or dyed in the visible spectral range and is present in the identification card in the form of a layer covering either its entire surface or part of it. The information in relief is produced by means of a laser beam recorder, the energy dosage of which is used to induce the locally controllable foaming process in the synthetic material compounded with chemical or physical blowing agents. The protection against forgery may be further increased by additionally photocuring the foamable synthetic layer.

Abstract: This invention relates to a plastic identification card with an improved signature panel. There is a problem with existig credit cards in that the existing signature can be obscured by printing over with a patch of clay composition similar to that used to provide the original signature panel. A new signature can then be applied. This problem is overcome by providing a signature panel which is sandwiched between the core stock and a protective transparent film. The signature panel comprises a layer of chemicals reactive under the pressure of a signature to release a colored dye conforming with the signature.

Abstract: An engraved image identification card has a translucent planar base member with a multiplicity of engraved scores extending into one of its surfaces with an opaque layer positioned adjacent either the engraved side of the translucent member or the non-engraved side of the translucent member opposite the engraved side to provide enhancement of the contrast between the engraved and non-engraved regions in the translucent member.

Abstract: A latent image identification card has a translucent base with a multiplicity of engraved scores extending through a generally opaque top layer into the base layer whereby a "negative" image appears when the background light is below a determinable value and a latent, "positive" image appears when the background light passing through the translucent base is above the determinable value.

Abstract: A double engraved identification card has a first planar member with a first engraved image in one of its major planar surfaces and a second planar member with a second engraved image in one of its major planar surfaces. The first and second engraved images are aligned in coincidence and the first and second planar members affixed to one another so as to form a single composite image. A slot is provided between the first and second planar members between the first and second engraved images. The slot has an edge access opening to selectively receive an opaque card through the edge opening into the slot region and prevent simultaneous observation of both the first and second engraved images.

Abstract: An identification card constructed of several film layers is provided with a monochrome or polychrome printed pattern. The printed pattern consists of partially overlapping color layers placed over each other and distributed over the surfaces of the film layers.The resulting printed pattern exhibits shadow effects in incident light which are reversed in transmitted light. A certain spatial effect and definite half-tone grading of the printed pattern can be achieved by the number and arrangement of the various printed layers.
