Description

Data support

The invention relates to a data carrier of according to the preamble of claim 1 and a method for the production of such a data carrier according to the preamble of claim 19.

Such data carriers serve as a card identity (identity card, check card, payment for means of transport, etc.), as an electronic means of payment (smart card), as an authorization card for a control of access, etc. and present as a characteristic of authenticity to less a safety feature with active structures diffraction optics.

EP-914,921 A1 describes a method and a device for injection molding of data carriers in the form of code cards according to the preamble of claim 1. The code card consists of two molded, flat plastic housings, which are grouped together form the code card, which include a hollow space, which offers space for a coil and other objects such as plastic or metal parts, magnets, holograms, photographs, etc.

EP 717 389 A1 describes a label identification, which includes a hologram between a layer transparent and a layer of adhesive.

US 4,304,809 describes a card of identity, which is formed by laminate and in which it is contained a card core with a window opening that Contains network images.

A data carrier is known from document CH-PS 672,285, which presents a body of plastic generated by injection molding, solid, without However, flexible with a recess for housing integrated circuits.

From WO 96/34730 a known method for the production of plastic cards provided in one or both sides of a printed label, in which you first generate the labels provided with magnetic registration stripes or safety features with structures with optical activity of diffraction. The back side of the labels or between the sides Back of two labels is added by molding material of plastic in a mold for injection molding, to obtain the thickness preset by the ISO of the cards. In this document you expressly refers to the technical details contained in the WO 96/34730 for printing plastic cards and to considerations regarding the molding technique by injection. For the protection of the indices applied on the label against mechanical influences a varnish is applied transparent protection.

EP-709,805 A2 describes the inclusion of holograms, magnetic stripes and modules electronics on the main surfaces of a card data, where electronic modules can be arranged for a contactless data exchange even inside the card. No injection molding method is used, but rather a granulate with the most diverse granulation is compressed together with the electronic module included at increased temperature.

Patterns included in plastic laminates of diffraction structures serve as protected characteristics against counterfeits for the certification of the authenticity of valuable items Particularly patterns, letters, etc. visually perceptible of diffraction structures, which are made visible successively during the rotation around one of the axes of the laminate and that generate a sequential cycle of images are know, for example, from patent documents CH-PS 659.433, EP-330.738 A1, EP-375,833 A1, EP-537,439 A1, while the construction of laminate layers is described in document CH-PS 680.170, the document EP-401,466 A1, etc.

Document CH-PS 678.835 shows a card with a photograph protected against a substitution. A brand of laminate with the pattern of structures of diffraction included covers a part of the attached photo on the card of the holder and a limiting part of the card. The photograph protrudes considerably along the surface of the document, so that the mark, in the area of the edge of the photograph covered by it, is particularly exposed to mechanical damage precisely where you have to check a Unauthorized substitution of photography. A card cover with a laminated film only delays the appearance of damage.

According to the document EP-741,370 A1 (= US 5 882 463), the characteristic safety consisting of ungrouped surface parts, small on a data carrier for protection against ejection of surface parts is completely coated or  partially with a scratch resistant varnish, which can be print and that has to be hardened advantageously with radiation UV

A disadvantage of known cards with a security feature, particularly of cards smart, identity cards, etc., is their tendency to mechanical damage, which occurs throughout the prolonged duration of use The cards are put under daily stress mechanical, in the purse or during the introduction through narrow metal diaphragm openings of reading devices  any kind. This poses great demands on resistance to rubbing the surface of the card, especially when in the security feature zone and other indexes, cards they are thickened and, therefore, the surface is not flat.

The object of the invention is to provide a Tension-free card, economical with high resistance to rubbing the safety feature and indicate a production method economic for such a card with these properties.

The goal solution is achieved by characteristics indicated in claims 1 and 19. obtain advantageous configurations of the invention from the dependent claims.

In Figure 1, 1 refers to a substrate, 2 a a protective layer, 3 to a security element with a layer covering 4 on a laminate 6 that includes an element of diffraction 5. The parts indicated with references 1 to 6 form jointly a layer joint 7 shown in a cross section in this representation for data carriers. This union of layers 7 has a thickness of less than 0.1 mm to about 2 mm, where for a typical flat data carrier according to the standard ISO 7816-1 dimensions are fixed with 85.4 mm x 54 mm with a thickness of 0.76 mm. However, it also they often prefer other thicknesses in the range of 0.6 mm to 1.0 mm

The substrate 1 is a flat metal object, paper, etc. or a plastic For high quality prepaid cards it they process plastic sheets with a thickness of 0.1 mm to 1.0 mm. In In this document, the substrate 1 is stamped out of a shaped sheet of plastic tape. The side facing the protective layer 2 of the substrate 1 is the information side 8, the other side of the substrate 1 is the back side 9. Substrate 1 has at least on the information side 8 information media in the form of 10 indexes, which are generated by printing technique and / or even in form of an attached image, for example, of the owner of the meat.

The security element 3 consists of a 6 laminate of at least two layers of varnish. Between two of these layers include diffraction elements 5. Elements of diffraction 5 can be holograms or form patterns composed of partial surfaces with molded relief structures microscopically thin, letters or sequences of images, which are described in the documents mentioned at the beginning. To the tilt or turn the safety element 3, the observer displays a modification of patterns, letters or a cycle of images of a sequence. The security elements 3 comprise in addition to usual holograms security features which were mentioned at the beginning, which are described in the documents that have been mentioned at that point. The element of security 3 can present a layer on the observation side 4 transparent hardened covering, up to 100 µm of thickness, which protects the laminate 6 against mechanical wear.

On the surface opposite the layer of covering 4 or the observation side, the laminate 6 is provided for adhesion, to join security element 3 on the information side 8 with the substrate 1. On the limiting surface structured with a microscopically fine relief of the elements diffraction 5 between the two layers of varnish, the index of refraction has to present a jump, so that the light that strikes from the semi-space of the observation side and diffracted in The diffraction elements 5 are reflected back to the semi-space. If both layers of varnish are transparent and if they have a difference in refractive index, the 10 indexes arranged under security element 3. A transparent dielectric with high refractive index, which is apply as a thin layer on the structured limiting surface,  the degree of reflection increases so that the indexes 10 they are only well visible under solid angles where they do not no diffracted light is reflected. On the other hand, a coating metallic (Al, Au, Cu, etc.) more than 10 nm thick on the structured limiting surface almost completely reflects light diffracted, so that the indexes 10 arranged below the security element 3 are not visible, unless the reason for the safety element 3 is composed of a fine line pattern of filigree, in which the metallic coating is applied in such way in the area of the lines, that the diffraction lines and reflectors are separated from neutral regions completely transparent, an embodiment described in the document that EP-537.439 A1 has been mentioned at the beginning. The realization of the joining of layers 7 in Figure 2 presented in the protective layer 2 a cavity 13 for housing a module with an integrated circuit, which is used for cards electronic prepaid phone, cards, smart cards, electronic purses, etc. The substrate 1 presents on the side of information 8 at least security element 3. Some of indices 10 may be visible through the element of security 3 or are arranged as print image 14 on the security element 3. Then the layer of 2 protection from transparent plastic and at the same time molds cavity 13 in the protective layer 2. The element of Security 3 is included completely without joints between the substrate 1 and protection layer 2.

In the embodiment according to Figure 3, the cavity 13 (Figure 2) is lined with a similar liner 15 to a thin metal or plastic sheet thimble, where the metal It acts as a screen against electrical disturbances. Before the Injection molding of the protective layer 2, the coating 15 is disposed in the place of the cavity 13 in the injection mold such that during the application of the protective layer 2 on the substrate 1 provided with the security element 3 (Figure 2), the liner 15 is surrounded by injection with the plastic of the protection layer 2 and is produced in protection layer 2 the coated cavity 13. The lining 15 is flush with the surface 11 (Figure 1) and widens towards surface 11, to host the module contact field with the integrated circuit. The lining 15 advantageously has at least one rib 16 peripheral outside on its outer side and a groove peripheral on the inner side, so that both the lining 15 in protection layer 2 as the module attached at a time back with a filling dough, for example, with the adhesive of Two components known by the Araldit® brand with the circuit integrated securely anchored in the coated cavity 13 by the teeth generated by nerve 16 and the groove. In a substrate thickness 1, the protective layer applied by molding can be too thin for liner housing 15. Advantageously, in the place of the cavity 13 it is punched in the substrate 1 a hole that houses the bottom of the lining 15, where during the generation of the layer of protection 2, the plastic fills free spaces that are presented in this hole.

In the realization of the joining of layers 7 in the Figure 4, the protection layer 2 is constructed from two plastic layers, 2 'outer protection layer and one layer intermediate 17 included between the outer protective layer 2 'and the substrate 1. The intermediate layer 17 and the external protection layer 2 'are generated in the form injection molding process successive after the respective surface equipment of information 8 (Figure 1) or the upper side 18 of the intermediate layer 17 with additional information means, for example, element of security 3, indexes 10, 10 ', print image 14, 14', etc.

Another embodiment presents instead of the element of security 3 adhered a directly generated diffraction pattern on the substrate 1. The information surface 8 is coated with an embossing layer 19 of a thermoplastic varnish and molded a relief with the diffraction structure 5 in the embossing layer 19. The diffraction structure 5 is covered with a varnish of 20 protection for relief protection during the process of molding Embossing layer 19 and protective varnish 20 or intermediate layer 17 correspond to laminate layers 6 (Figure 1). To generate the required optical effect, the surface structured limitation of embossing layer 19 is made as in laminate 6 (Figure 1). The indexes 10, 10 'arranged over embossing layer 19 and diffraction structures 5 are included and covered by intermediate layer 17 applied in a First clear plastic molding process. Top side 18 which borders the outer protection layer 2 'of the layer intermediate 17 carries the print image 14, 14 'and / or at least one additional security element 3.

In a special embodiment of the invention, the upper side 18 of the inner layer 17 additionally presents or of uniquely shaped optically active relief structures 21, molded by an injection tool, which modify the light incident like Fresnel lens, like a mosaic of patterns of diffraction or as a hologram. 2 'external protection layer covers print image 14 and / or security element 3 and / or relief structures 21 where the limiting surface structured is done at least in the area of the structures of relief 21 as in the security element 3 such that produces a jump in the index of refraction, so that the optical effect required. Production by injection molding it has as an advantage a great precision in the thickness of the layer intermediate 17. Particularly, the optical interaction of the information media on the side top 18 with the information media on the side of information 8 by the thickness of the intermediate layer 17. The provision of information media (security elements 3, diffraction structures 5, indexes 10, 10 ', print images 14, 14 ', relief structures 21, etc.) can be performed in the recording, describing the optical effects that can be obtained thus in WO 97/19820.

Figure 5 shows an embodiment of the joint of layers 7 with an integrated circuit 23 that can be put into contact with the environment according to the document that has been mentioned at the beginning EP-709.805 A2 by antennas 22, which are contained together with the security element 3 at the junction of layers 7.

Another embodiment of the joining of layers 7 presents a protective layer 2 (Figure 2) constructed from at least two 24, 25 portions of plastic materials that differ each. In the example drawn, during molding, plastics liquids have been supplied from the left side and from the right of joining layers 7. Corresponding to the pressures used during injection, plastics flow to different speed on information side 8 (Figure 1) and they bump into each other at a predetermined site. Advantageously, the Injection of the protective layer 2 is done in two stages, where first portion 24 is applied first with one of the plastics on the substrate 1, for example, in the area of safety element 3 and then the other one is molded plastic for the second portion 25. In a combination of this embodiment with the embodiment variant according to Figure 4, the first portion 24 has only the thickness of the layer intermediate 17 (Figure 4) and covers the substrate 1, for example, in the security element zone 3. Second portion 25 applies in the thickness of the protective layer 2, where the second portion 25 gets in the area of the first portion 24 only thickness of the outer protection layer 2 '(Figure 4). For the molding of multi-stage plastics molds are needed for each stage corresponding injection.

Plastics are selected in such a way that establish an intimate bond and not only with respect to the substrate 1 or with respect to laminate 6 (Figure 1) of the safety element 3, but also between portions 24, 25. As an example, the plastics of the two portions 24, 25 differ only for its transparency or coloring. The protection layer 2 guarantees in the area of security element 3 the ability to visual and / or machine detection of security element 3 in the predetermined range of radiation wavelength electromagnetic

In Figure 6, the layer joint 7 contains a photograph 26 applied on the information side 8 on the substrate 1 with a security feature 3 arranged as a certification mark on a part of the photograph 26. Front the object in document CH-PS 678.835 mentioned at the beginning as a state of the art the advantage of the union of layers 7, because the protection of photography 26 certified is enhanced by the 2 protection layer mechanical influences Surface 11 parallel to the side plane posterior 9, completely smooth does not present any point of attack for mechanical influences. The union of layers 7 does not present any coating with thin plastic sheets on the surface 11 or on the back side 9 (Figure 1), which can be detached at length of use

In Figure 7 the joint of layers 7 is molded (Figure 6) as data carrier 27 plane. The data carrier 27 presents on the information side 8 (Figure 6) supports of information arranged in an illustrative manner, visible through protection layer 2 (Figure 6), for example, photograph 26 and the security element 3 that partially overlaps the photograph 26, text fields 29, 30, etc. In text fields 29, 30 are house indexes 10 (Figure 1) or print images 14 (Figure 4) in at least one plane. Security element 3 and the thick protective layer 2 effectively avoid a replacement of photograph 26. The equipment of data carrier 27 is complete in a given case through the module with the circuit integrated for electronically modifiable data, where in the view of Figure 7 only a contact field 28 is visible for data exchange with the integrated circuit.

The data carrier 27 is represented in the Figure 7a from the back side 9. The back side 9 can be adhere a strip of information 31 parallel to the extension longitudinal data carrier 27, by way of example, a strip with a magnetizable layer or a known strip from EP-718,795 A1 with optical marks. To both sides of the information strip 31 is applied in partial areas 32 on the back side 9 the hardened varnish layer 12 (Figure 1) with ultraviolet radiation. This application protects the information strip 31, since it is down from the varnish surface, on the side, by overlapping, the visually detectable information in partial areas 32. The varnish layer 12 can form a simple dot pattern or be Apply over the entire surface.

The data carrier 27 of Figure 8 presents a structured surface 11. These surface structures they are composed of partial surfaces 32 of surface 11 raised above the surface plane 11 and / or introduced into the surface 11 and may represent graphic motifs, images or texts in letters or even in Braille; by way of example, the raised partial surfaces 32 in the drawing of Figure 8 They form the word VALID. Since the protective layer 2 (Figure 1) it is transparent, security element 3, indexes 10 (Figure 1) in text fields 29, 30, photograph 26 (Figure 7), etc., despite this, they are visible on the information side 8 of the substrate 1.

A longitudinal cut along the line A / A 'by the data carrier 27 is shown in Figure 8a. The Production of the joining of layers 7 is carried out in a mold injection 34, 35, comprising a top part 34 and a part base 35. In the drawing, the upper part 34 and the base part 35 have been separated and the joining of layers 7 is arranged between the parts 34, 35 of the injection mold. The security element 3 arranged on the information side 8 is completely included in the protection layer 2 and is covered by it. The layer of protection 2 protects the information carriers 3, 10 (Figure 1), 14 (Figure 4), 26 (Figure 6) on the information side 8 and extends over the entire substrate 1. Partial surfaces 33 only about 0.1 mm protrude above the plane of the surface 11, however, despite this they are well visible and even palpable. The cross-sectional shape due to mold demolding of partial surfaces 33 offers no point of action for mechanical destruction.

The rational production of the layer 7 union is performs by injection molding of the protective layer 2. The substrate 1 with information carrier 3, 10 (Figure 1), 14 (Figure 4), 26 (Figure 6) arranged on the information side 8 is included in the base part 35 of the injection mold, where the back side 9 (Figure 1) contacts the surface background 36 of the base part 35. The following are grouped two parts 34, 35 and the injection mold is closed, in such a way that on the information side 8 there is a hollow space with the volume of the protective layer 2. Through a channel of injection 37 the plastic is pressed into the hollow space heating fluid, where ventilation channels 39 in the upper part 34 allow a complete filling of the space hole. The structure of surface 11 and surfaces partial 33 is predetermined by a configuration corresponding of the inner surface 36 of the upper part 3. 4.

So that the substrate 1 cannot be raised during the injection of the plastic from the bottom surface 36, the substrate 1 is held, for example, by negative pressure on the bottom surface 36. For this purpose suction 38 included in the bottom surface 36, in which It generates negative pressure through a vacuum pump. Typically, the protective layer 2 produced in this way has at least the same thickness as substrate 1, however, preferably, the protection layer 2 is at least twice as thick as the substrate 1. The use of a too thin substrate 1 houses the danger of substrate 1 producing folds during molding by injection, it is founded or later it can be detached as A laminated film.

The plastic introduced by layer injection protection 2 binds intimately with the substrate 1 and the element safety 3 and cools, however, due to the capacity thermal of the substrate 1, so quickly that the substrate 1 and the information media (especially security element 3) a Despite this they are not damaged. EP-401,466 A1 describes the effects of an excessive heat supply on the security element 3. Information media 3, 10, 14, 26 They are thermally bonded with the substrate material 1, so that the information supports 3, 10, 14, 26 during the generation of protection layer 2 or intermediate layer 17 (Figure 4) Do not detach from substrate 1 and keep your default layout. The possible remains that remain after the demolding of an injection point 40 at the edge of the Card are removed by a cut out of the card shape. The protection layer 2 (or 2 'and 17) and substrate 1 are sufficiently flexible to meet card flexibility requirements of data.

For the production of the joining of layers 7 of according to the drawing in Figure 4 two molds of injection 34 (Figure 8a), 35 (Figure 8a), one that first enable injection molding for intermediate layer 17 and one second for injection molding of the protective layer external 2 '. It is sufficient to replace only the upper part 34 to ensure the necessary hollow space respectively for the injection molding.

Again with respect to Figure 8a. How plastic materials for injection of protective layer 2 are suitable, among others, the group of polyesters, for example, polyethylene terephthalate (PETP, Mylar®), polybutyleneterephthalate (PBT), polycarbonate (PC, Macrolon®), etc., or  polyolefins such as polyethylene (PE), polypropylene (PP), etc. or polymethylmethacrylate (PMMA), a copolymer such as, by example, copolymers of Acrylonitrile Butadiene Stirene (ABS), or polyvinylchloride (PVC), polyamide (PA), etc. In particular, PETP can already be injected at a temperature of 70-140ºC, it is characterized by high resistance to wear and is gas impermeable and has dimensional stability. These plastics can also be obtained as sheets for substrate 1. When the substrate 1 and the protective layer 2 are produced from suitable plastic materials, the union between the substrate 1 and the protection layer 2 it is no longer possible separate and form a single card body. Optimal functions are given  in a union of layers 7, which presents the same plastics for the substrate 1 and protection layer 2. They are preferred materials ABS, PETP, PC, PMMA, etc., which can be supplied both transparent as glass as in transparent or opaque quality colored. As an example, the protective layer 2, for the light visually perceptible and adjacent parts of the spectrum of the electromagnetic radiation, can be completely transparent (= "transparent like glass") or be transparent for at least a part of the visible wavelength range or only for light not visually noticeable. Plastics contain advantageously also fluorescent dyes as characteristic detection.

The opaque qualities are rather suitable for the substrate 1. The use of transparent qualities for the substrate 1 it allows to observe the security element 3 through the side posterior 9 (Figure 1). In addition, by printing on record of indexes 10 (Figure 1), 14 (Figure 2) on the information side 8 (Figure 1) and information on the back side 9 (Figure 1) so-called records of coincidence, where indexes 10, 14 on the information side and the information on the back side 9 represents patterns discrete, which are grouped only backlit to form Letters, figures, graphic patterns, emblems and the like.

If the safety elements 3 used in the Embodiments that have been described also contain information that can be read by radiation, for example, a general or individual access number, which is represented by a combination of the diffraction elements 5 (Figure 5), the protection layer 2 must be set transparent at least for radiation for reading. Machine readable information can be contained alone or together with visible patterns visually in the security element 3. Yes security element 3 features diffraction elements 5 machine-readable only by infrared radiation, by way of example, the layer of Protection 2 can be transparent only for infrared light; for visible light, however, protection layer 2 is not transparent and colored, by way of example, in black. If he substrate 1 is composed of a plastic of this quality also you can read the information through the substrate 1.

Figure 9 shows an embodiment of the joint of layers 7 (Figure 8a) with a safety element 3 (Figure 8a) generated in accordance with the teachings of the document EP-741,370 A1 mentioned at the beginning. He safety element 3 consists of small rolling parts 41, that are arranged in the form of points, rectangles, pieces of line-shaped surface with very small width, typically less than 0.5 mm etc., in a predetermined pattern as rings circular, guilloche, graphic representations, strokes of writing, etc., on the information side 8. The pieces of the laminate 41 together form the security element 3. In the cross section depicted of the layer joint 7 of the Figure 9 only cuts from the safety element are visible the rolling parts 41 adhered on the substrate 1.

Protection layer 2 has structures 42 flat molded on the surface 11, for example, of a lens of Fresnel As an additional structuring are provided for data carriers 27 (Figure 8) elevated signs 43 of writing braille, to obtain 27 data carriers that can be distinguished even for the visually impaired.

The extension of protection layer 2 is limited, by way of example, in another embodiment to a part of the information side 8 of the substrate 1. The substrate 1 and the layer of protection 2 are linked together inseparably due to the particularly intimate union on the common limiting surface.

The different characteristics of the embodiments indicated in this document can be combined freely. Particularly, the free surface 11, 11 'is also You can print conventionally.

The advantage in all these embodiments is the better protection of all indexes on the information side 8 (Figure 6) or on the upper side 18 (Figure 4) and particularly of the safety element 3 (Figure 2) against tampering fraudulent or vandalism, however, also against wear and tear scratches, which are inevitable during daily use.
