multi-layer forgery-proof identity card

The invention relates to the well-known multi-layer identity cards, as they are for people, but also for oachen UDlich if necessary, and has the task of _{creating a document of this type that is particularly good:; e t} >; en forgery-proofed documents, ^ s is intended to ensure that the owner of such an ID card removes, changes or transcribes individual original information. can without the person to whom the ID is presented being able to perceive that the original information has been falsified.

G-egenstana of the invention is a multi-layer anti-counterfeit Identity card that is marked by

1. a fluorescent element,

2. a marking and control element

and J. an embedded in a transparent film Carrier element for identity information with which Provided that the marking and control element aÄ for ultraviolet rays opaque Contains otoff, which is imperceptible in visible light, but differs in ultraviolet light Light contrasts with the fluorescent element o

Often only the carrier element and the luarkierungs- and rvoritrollelement can be combined in a transparent film, while the fluox-escent element forms a separate part, for example, the carrier element consists of an inner part in the form of a photo, fingerprint or the like, or a piece of paper or paper, or both at the same time, preferably covered with an otoff that can accept typescript, printing ink, ink, etc. The marking and control elements are combined with this carrier element.

There i-'i'üt various methods of falsifying the well-known multilayered identity cards. 80 you can peel off the foil and make cadings or corrections on the exposed cardboard or paper element or you can detach the photo or other picture and replace it with another, and after the change made, the cover foil can be reattached. In any case of such a change, however, the luster that the fluorescent element and the UV-impermeable marking element make visible in cooperation is inevitably also irrevocably changed, as soon as the ID card becomes a UV source. During this check of the ID, therefore, unauthorized changes to the document will be discovered with certainty.

In principle, the invention does not only apply for ID cards, but for absolutely all documents, v; ie Share certificates, contracts, passports, free papers, all of which are falsifications EiuV-lic ;. are and should be excluded "

Identity card according to FIG. 1 shows an area (10) for a photo or the like and areas (11) for other identity data, such as comes, addresses, etc. In daylight or with visible artificial light, the ID appears like one of the usual multi-layer ID cards of the state of the art. Under UV light, on the other hand, it shows the appearance shown in FIG. If necessary, the wamenszug or other personal data can also be set with such ink or printing ink that it is only visible under UV light. The remaining parts of the identity card in this embodiment show no different appearance under UV light than they do in the visible, because they do not contain an overlapping arrangement of fluorescent element and UV-opaque marking element. Only because the numbers 2-2-2 are printed in UV-impermeable color over the fluorescent light in the strip 12, the numbers 2-2-2 are visible in UV light. The lettering and imprints can also be made legible under UV light, and only under this, if they are applied to the carrier elements with a UV-transparent ink or paint.

Lian can also use the core (13)> whether it is a photo or a card that is simply labeled or printed, in some way with one regular or irregular printing of characters, jäuchstaoen, Print numbers or other symbols in UV-impermeable printing ink, so that at least a 'partial area of the Tr Lp; he elements under UV light a certain and known imprint visible in UV light can be, regardless of where otherwise for the individual case Another marking and control element, which is also UV-impermeable Fabric is arranged.

Fig. 3 shows the rear view of the pass of Figs. 1, 2, like it appears in UV light. Here you can see within the stripe (12) the numbers 2-2-2 reversed. In this case, the core (13) of the ID card is transparent or translucent, if it were opaque,

so you would get the numbers 2-2-2 on its front cannot see from the rear.

in most cases, however, there will also be, for example, on the rear of the photo (10) any data or a drawing pattern attached in UV-opaque otoff, which is then visible in UV light as shown in FIG. 5 in field 10.

In addition, it can also be used for marking and control marks in UV-impermeable .Fabric can be attached to the foils with which the multilayer ID card laminate is produced, for example such a film on its entire surface, or on 'filing surfaces, with a marking that is invisible in visible light If UV-impermeable material is printed, these markings are also printed an integral part of the multilayer passport of the invention.

If a foil of the ID card laminate is printed on its entire surface with markings in invisible printing ink, these markings are only visible under UV light where they are underlaid with a surface of the fluorescent element. Therefore, in their narrow edge areas, even in UV light, Fig. 2 and Fig. 2 do not show any marking symbols, because it is assumed that the fluorescent element is only as large as the carrier element (IJ; and does not protrude beyond it 2 and $ on a fluorescent surface, which corresponds at least to the size of its outer circumference, then in the edge strip ^ 14; ^ Fig. 4; under UV light the control characters 2-2 printed on the transparent film -2 in contrast to perceive the fluoro essence of the surface, the kineinatiscxie reversal is also possible, namely that the marking and ilontr oll characters in the marginal strip; 14) are written or printed with a fluorescent letter. These become visible under UV light when they are combined with surfaces made of UV-impermeable fabric.

a middle section from 15), which is covered with a - »toff (16). The middle part (15) can be a thin layer made of a translucent, transparent or opaque material such as paper, cardboard, aluminum, steel, glass, plastic, such as x-olyamd, polyethylene, ivlylar and the like, or a fabric made of natural or artificial fibers , for example glass, linen or the like exist. In a thin layer, these materials give the ID the necessary flexibility. The material of the Iittelceils ~ \ 15j v / ill be chosen so that it adhesively ^ escnichtet with the coating material (16) to be used in the case concerned or im- W can be pregnated. This wiater-ial (16) should completely surround and envelop the inner part (15; this is welded.

The inner part (15) can consist of photographic paper or film with a photo of the owner or any other document. i) r can also be composed of several segments. However, he does not need to fill in the entire laminate in terms of width and length. For example, the inner part can be formed from a plurality of non-touching surfaces arranged next to one another, the spaces between which are filled by film surfaces that are welded to one another. These foil surfaces of the interspaces, which are united with one another, can also enclose fluorescent material and / or UV-impermeable material. In Fig. 5, the photo (17) is shown in a greatly enlarged section, which takes up the area (10; of iig. 1. It is generally intimately connected to the covered inner part (15) by being in the same covering material (16 If necessary, the coating material (16) can also completely enclose the light image (17). The coating material (16) is usually a high-polymer material, such as polyethylene, polypropylene, raraffin waxes, polyvinyl chloride , Polyamide, polyethylene glycol terephthalate, and the like

fabrics can be welded in the braid. If, however, a film is used which is not or only at much higher temperatures, then it can first be covered with a whisker layer; has a high welding temperature; cover it with a heat-sealable material and print on the other side with a fluorescent material and / or a UV-impermeable otoff, whereupon the nei-ßsiegelschicht, which is made of ± oly ^; ethylene, uellulose acetate, uellulose acetate butyrate or similar material, used to weld the polypropylene film to another film, which in turn is heat sealable or carries a heat seal layer. The term "heat seal light" also includes layers which are applied in a known manner to a photo or the like with the aid of an aerosol spray device in order to attach it to the central part, for example a central part (15) made of paper can be impregnated with rolyethylene whereupon the photo (I " ¹ ) is embedded in the top layer or glued onto it. Then the cover material (16} can be sprayed over the entire photo (17) so that the latter is covered on all sides with the transparent cover material (16) On the surface of the coating material (16) or on the fluorescent substance, other identification data can now be written or imprinted in print or ink. It is therefore not absolutely necessary for these identification data to be applied to the innermost oil layer 15. It actually has advantages if they are not attached there.

Underneath the photo ^ I ¹ ?) Is a layer (18; arranged in Fig. 5, which can consist of a fluorescent material. This is followed by an adhesive layer (19), which firmly connects the photo with a film ^ 16). The adhesive is generally a transparent substance, especially if, as shown in FIG. 3, the marking characters formed by the combination of UY-impermeable material and fluorescent substance are also to be visible from the rear side in UV light. In some cases the fluorescent substance itself can act as an adhesive

In other cases, the adhesive can be dispensed with entirely, because the photo is sufficient by welding on the cover film (20) is determined.

To the right of the photo (17) is a layer (21) of fluorescent fabric arranged. It is applied as a »stripe to the surface of the coated inner piece (15), but it can also be used if necessary be applied directly to the inner part (15), because the fluores decorative fabric can be arranged Deliebig, ^ r also carries the Application of a UV-impermeable material serving as a filter, which is contained in the Drawing is not shown, for example in the form of the Zanlenstreifens (12.) νυη Fig. 2.

The outer or cover sheet (22; can be made, for example, of polyethylene glycol terephthalate, a commercial product from EI DuPont dex ^ emours, under the trademark "MTLAR", which is bonded to a layer of another plastic, generally polyethylene, (20) which It is compatible and can be welded to the cover (16). The latter generally consists of polyethylene and is seamlessly welded to the polyethylene layer (20 ^ of the outer cover sheet (22). As a result, inscriptions, imprints etc., which are applied to the layer (16, or which are not (.20) applied, completely and indissolubly embedded in the polyethylene from both conductors. Of course, any other plastics can be used in this context instead of polyethylene , provided that the notches (Ic, and (20) each consist of the same plastic, and therefore are laminated under the action of pressure and temperature weld together. Also the layers, 20; and {22j flow into each other during this operation and form a firmly coherent layer.

in principle, the multi-layer ID card laminates or explore laminates of the invention can be made using a single plastic, for example only polyethylene. Is preferable but that you need a tough and scratch-resistant film for the outer layer, For example, made of polyesters are used. . <express this. »but matter In general, you never have to agree with yourself for practical reasons combine them with other plastics that

contribute the required weldability. Laminating the üDirectly arranged plastic layers takes place according to the known Methods where just enough heat and pressure to come about the welding must be expended.

It is readily apparent that in the document laminate of the invention, all printed or written data that can be recognized in the visible and / or UV spectrum are enclosed in the interior of the laminate, so that they are only accessible to a national with at least partial destruction of the unit and cannot be restored from this to the original state, ie with the control marking intact. Like the cut of Ji'ig. 5 shows, the different identification data can originally lie in different planes or can be pressed into different planes by the pressure during lamination, so that, for example, a handwritten signature (11) does not come to lie over its entire length in a single plane because, for example, the writer uses a different type of print at individual points, which has a different penetration depth into the layer to be described. This also effectively thwarted intended forgeries. If one arranges the fluorescent element and the UV-impermeable element in combination on the inner part (15), the marking in the coating (16;

An ink, printing ink or a fluorescent element is used as the fluorescent element Powder made of a permanent fluorescent material with the longest possible lifespan, its luminescence even with repeated exposure does not wear off with UV rays. Suitable substances of this type are, for example, beta ^ aphthol, novocaine, bensidine, p-phenylenediamine, Liatriumsalieylat, Anilin, Antipyrin, ResDomn, ßariumplatincyanOr, iVoli'ramate and the like.

Gravel kustier can also be camouflaged if necessary by applying similar shades of color to the shepherd's ground surfaces. Individual partial areas, such as the haum for a bar ο Lev a signature, can also be surrounded by a dew made of fluorescent material, finally various identification numbers or marks can be arranged in one or more corners of the ID card, if you already suspect that the functions of the fluorescent element and the UV-impermeable element can also be interchanged in the sense that the entire text of the identification document, i.e. the identification data and the signatures, can be found in a fluorescent otoff, ink or printing ink on the inner part and / or the foils and anorings with the UV-opaque element in the intermediate surfaces in such a way that only the surfaces that make up the customer text are exposed and should be visible under UV light.

Due to their different optical characteristics, both elements work together in such a way that they make certain signs, patterns or legends visible to the person using the identity document in UV light has to be checked, are known on the basis of an agreement and their intactness proves that the certificate has not subsequently been falsified by unauthorized persons. Of course, ax identification documents are not inviolable, but falsification attempts are accessible. The technical effect of the invention lies in the fact that no falsification can be carried out without the two issuers and recipients of the certificate agreeing on contrast marking of fluorescent element and UV-impermeable element being changed, and that therefore the Kachprüfung is unfe.nl :: ar makes it clear in the UV law whether the document is in tact or has been falsified.
