Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting technology, specifically to an anti-counterfeiting element and anti-counterfeiting product. Background Technology

[0002] In recent years, magnetic materials and machine-readable anti-counterfeiting technologies have been increasingly used in the anti-counterfeiting field. Integrating magnetic machine-readable technology with public anti-counterfeiting features (such as optical features) into a single anti-counterfeiting element has become an increasingly popular choice in the international anti-counterfeiting industry. Patent CN100532124C proposes an optically variable magnetic structure with interference units, a reflective layer, and a magnetic layer, exhibiting color-changing effects and magnetic characteristics depending on the viewing angle. Furthermore, patent EP2020 / 025374 integrates two or more different magnetic materials with optically variable security elements to form machine-readable multi-magnetic codes.

[0003] In known technologies, anti-counterfeiting elements formed by integrating magnetic codes with public features are all copied onto paper in a random manner. The position of the magnetic code on each small bill is random, making machine detection complex.

[0004] Integrating magnetic coding technology with public anti-counterfeiting features, and matching it with positioning and deployment technology, allows for precise placement within banknotes. An existing application example is the Honduran 200 Lempira commemorative banknote (issued in 2021), which effectively integrates Gallaxy dynamic optical variable technology, magnetic coding technology, and positioning and deployment technology into its security thread, ensuring accurate positioning with the banknote design. It can be seen that the magnetic coding sequence is identical in every small denomination of the banknote, facilitating machine detection and reading.

[0005] In the current technology, there is no precedent for accurately locating the magnetic coding sequence with the position of the banknote window. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the existing anti-counterfeiting elements do not accurately position the magnetic code sequence and the banknote window position, thereby providing an anti-counterfeiting element and anti-counterfeiting product that can accurately position the magnetic code sequence and the banknote window position.

[0007] To address the above problems, the present invention provides a magnetic anti-counterfeiting element, comprising:

[0008] The substrate has magnetic anti-counterfeiting areas on its surface and / or opposite surface, the magnetic anti-counterfeiting areas having a fixed number and / or regular magnetic coding sequence, and the paper embedded area of ​​the substrate having a feature coding sequence.

[0009] The magnetic anti-counterfeiting area and the window opening have a defined relative positional relationship, and each window opening corresponds to a region magnetic coding sequence, and the region magnetic coding sequences have distinguishing features;

[0010] The magnetic coding sequence of the region is determined at the position on the ticket, and the magnetic anti-counterfeiting area forms a set of complete magnetic coding sequences along the preset direction Y.

[0011] Optionally, the feature encoding sequence includes one or more of magnetic features and fluorescence features.

[0012] Optionally, the plurality of said regional magnetic coding sequences are composed of magnetic materials with different coercive magnetic field strengths, wherein the coercive magnetic field strength of the magnetic materials is 50 Oe-4000 Oe.

[0013] Optionally, the plurality of said regional magnetic coding sequences are composed of the same magnetic material with different remanence, wherein the remanence of said magnetic material is from 50 nWb / m to 700 nWb / m.

[0014] Optionally, the regional magnetic encoding sequence consists of rectangular magnetic encoding and / or magnetic text encoding.

[0015] Optionally, the first region magnetic coding sequence and the second region magnetic coding sequence are composed of rectangular magnetic codes and have different magnetic code distributions.

[0016] Optionally, the substrate is one of paper or film.

[0017] Optionally, the length of the magnetic coding sequence is between 0.3 mm and 7.0 mm, and the width is between 0.5 mm and 10 mm.

[0018] An anti-counterfeiting product, comprising the aforementioned anti-counterfeiting element.

[0019] Optionally, the anti-counterfeiting element is placed in the anti-counterfeiting product in a windowed manner.

[0020] Optionally, the anti-counterfeiting product includes any one of banknotes, banknotes, tickets, certificates, documents, and credit cards.

[0021] The present invention has the following advantages:

[0022] 1. The anti-counterfeiting element provided by this invention includes a substrate, on the surface and / or opposite surface of which magnetic anti-counterfeiting areas are provided. Each magnetic anti-counterfeiting area has a fixed number and / or regular magnetic coding sequence, and the paper-embedded area of ​​the substrate has a characteristic coding sequence. The magnetic anti-counterfeiting areas and the window opening have a defined relative positional relationship. Each window opening corresponds to a magnetic coding sequence in the area, and the magnetic coding sequence in each area is composed of corresponding magnetic coding sequences. Furthermore, the magnetic coding sequences in each area have distinguishing features for anti-counterfeiting detection. This anti-counterfeiting element precisely positions the magnetic coding sequence relative to the window opening of the banknote, resulting in excellent anti-counterfeiting performance.

[0023] 2. The anti-counterfeiting element provided by this invention distinguishes different regions of the magnetic coding sequence by the following characteristics: different remanence of the magnetic material used for the magnetic coding, and / or different coercive magnetic field strength of the magnetic material used for the magnetic coding, and / or different magnetic coding distribution, and / or different anisotropic characteristics of the magnetic coding. Therefore, the magnetic coding sequences of the two regions have distinguishable characteristics during reading, resulting in a better anti-counterfeiting effect.

[0024] 3. The anti-counterfeiting element provided by the present invention has a regional magnetic coding sequence composed of rectangular magnetic codes and / or magnetic text codes, so the regional magnetic coding sequence has a variety of appearance shapes, enhancing design and aesthetics.

[0025] 4. The anti-counterfeiting element provided by this invention also has a feature coding sequence embedded in the paper area.

The anti-counterfeiting effect is good, and the machine reading difficulty is low. Attached Figure Description

[0038] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Each ticket has preset multi-dimensional magnetic code information, which avoids the randomness of the magnetic code information of the past. Through the application of window area coding and full ticket coding, the anti-counterfeiting dimension is greatly improved, and it is also easier for machines to identify.

[0043] Example 1

[0044] like Figure 1 This is a preferred embodiment of the anti-counterfeiting element of the present invention. This anti-counterfeiting element can be used to make anti-counterfeiting products. Furthermore, this anti-counterfeiting element accurately positions the magnetic coding sequence 3 with the window 2 of the banknote, making it easy for machines to read and reducing the difficulty of machine detection.

[0045] The aforementioned anti-counterfeiting element includes: a substrate 1. The substrate 1 is paper or a transparent medium film, generally formed from a film material with good physical and chemical resistance and high mechanical strength. For example, it can be a polyethylene terephthalate (PET) film, a polyethylene naphthalate (PEN) film, or a polypropylene (PP) film, etc. In this embodiment, the substrate 1 is preferably a biaxially oriented polypropylene (BOPP) film. Magnetic anti-counterfeiting areas are provided on the surface and / or opposite surface of the substrate 1. The number of magnetic anti-counterfeiting areas can be one or more. Each magnetic anti-counterfeiting area has a fixed number and / or regular magnetic coding sequence 3. Furthermore, the magnetic anti-counterfeiting areas and the window openings 2 have a defined relative positional relationship, i.e., each window opening 2 corresponds to one or more magnetic anti-counterfeiting areas. Each window opening 2 corresponds to a regional magnetic coding sequence for machine reading. The regional magnetic coding sequence consists of the magnetic coding sequences 3 included in the corresponding magnetic anti-counterfeiting area. Different regional magnetic coding sequences have distinguishing features. The regional magnetic coding sequence is determined at the ticket surface position, and detecting the magnetic anti-counterfeiting area along a preset direction Y can form a complete magnetic coding sequence. Complete magnetic coding sequences include regional magnetic coding sequences, as well as new features arising from the correlation of features between regional magnetic coding sequences, such as high-low coding, dual coercivity, wide-narrow coding, and magnetic fluorescence coding.

[0046] Specifically, such as Figure 1As shown, in this embodiment, two magnetic anti-counterfeiting areas and two window openings 2 are arranged at intervals along the vertical direction Y, with each magnetic anti-counterfeiting area corresponding to one window opening 2. During inspection, the magnetic sensor reads the two window openings 2 along the vertical direction Y, obtaining two sets of regional magnetic code sequences. The two sets of regional magnetic code sequences have distinguishing features, namely: the remanence of the magnetic material in the magnetic codes of the two sets of regional magnetic code sequences 3 is different, and / or the coercive magnetic field strength of the magnetic material in the magnetic codes is different, and / or the magnetic code distribution is different, and / or the magnetic code anisotropy characteristics are different, thus enabling anti-counterfeiting identification. Specifically, the remanence of the magnetic material in the magnetic codes is 50 nWb / m to 700 nWb / m; the coercive magnetic field strength of the magnetic material in the magnetic codes is 50 Oe to 4000 Oe; the different magnetic code distribution refers to the different number and distribution positions of the magnetic codes included in the regional magnetic code sequences; and the magnetic anisotropy characteristics of the magnetic codes are horizontal, vertical, 45-degree, and other directions. Because the magnetic coding sequence 3 is precisely positioned within the window 2, it is easy for the equipment to read and the detection difficulty is reduced.

[0047] Furthermore, in this embodiment, the remanence of the magnetic codes in the two sets of regional magnetic coding sequences 3 is different. One set of magnetic codes has a remanence of 100±20Wb / m, and the other set has a remanence of 400n±80Wb / m. The two sets of regional magnetic coding sequences also have different magnetic code distributions. The first regional magnetic coding sequence includes four magnetic coding sequences 3, all of which are rectangular magnetic codes. The first and third rectangular magnetic codes are the same, as are the second and fourth. The length of the first rectangular magnetic code is greater than that of the second. The second regional magnetic coding sequence includes two magnetic coding sequences 3, both of which are also rectangular magnetic codes. However, the rectangular magnetic codes in the second magnetic anti-counterfeiting area are different from those in the first magnetic anti-counterfeiting area. The length of the magnetic coding sequence 3 is [0.3, 7] mm, and the width is [0.5, 10] mm.

[0048] In other embodiments, the regional magnetic coding sequence may also consist of magnetic character coding, or a combination of rectangular magnetic coding and magnetic character coding.

[0049] The anti-counterfeiting elements provided in this embodiment can be used to make security lines, stripes, labels, and markings, and can also be adhered to various items through various adhesive mechanisms, such as transferring them to high-security products and high-value-added products like banknotes and credit cards.

[0050] This embodiment also provides an anti-counterfeiting product, including the aforementioned anti-counterfeiting element, wherein the anti-counterfeiting element is disposed in the anti-counterfeiting product in a windowed manner. The anti-counterfeiting product includes, but is not limited to, one of the following: banknotes, bank drafts, tickets, certificates, documents, or credit cards. After the aforementioned anti-counterfeiting element is applied to the anti-counterfeiting product, the machine can identify the anti-counterfeiting status by reading the magnetic code sequence of the area of ​​the window 2.

[0051] Example 2

[0052] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 lies in the different distinguishing features of the regional magnetic coding sequences of the two open windows 2. The rest of the structure is the same as that of Embodiment 1, so it will not be described again.

[0053] In this embodiment, the magnetic coding sequence 3 of the first regional magnetic coding sequence is composed of a magnetic material with magnetic anisotropy, and the first regional magnetic coding sequence consists of four identical rectangular magnetic codes, while the second regional magnetic coding sequence consists of four identical magnetic text codes. The two regional magnetic coding sequences have easily distinguishable different shapes.

[0054] Example 3

[0055] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the substrate 1 is provided with three open windows 2 and three magnetic anti-counterfeiting areas, and the magnetic anti-counterfeiting areas and open windows 2 correspond one-to-one. Moreover, the coercive magnetic field strengths of the magnetic codes in the three sets of magnetic coding sequences 3 are different, and the coercive magnetic field strengths are 300±50Oe, 1300±100Oe, and 3000±500Oe, respectively.

[0056] The magnetic coding sequence of the area corresponding to the first window 2 consists of two identical rectangular magnetic codes, the magnetic coding sequence of the area corresponding to the second window 2 consists of two identical magnetic text codes, and the magnetic coding sequence of the area corresponding to the third window 2 consists of two identical rectangular magnetic codes. Furthermore, the rectangular magnetic codes of the third window 2 have different lengths than those of the rectangular magnetic codes of the first window 2.

[0057] Example 4

[0058] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the substrate 1 is provided with a feature coding sequence 4. The rest of the structure is the same as that of Embodiment 1, so it will not be described again.

[0059] Furthermore, the feature coding sequence 4 is set in the embedded area of ​​the substrate 1, that is, the feature coding sequence 4 is set on the substrate 1 by embedding, unlike the magnetic coding sequence 3 which is set on the substrate 1 by opening a window. The feature coding sequence 4 includes one or more of magnetic features and fluorescent features. Specifically, in this embodiment, the feature coding sequence 4 is set between two open windows 2, and the feature coding sequence 4 is a fluorescent feature, that is, it can emit fluorescence of a specific wavelength when excited by a fluorescent light source. The anti-counterfeiting detection is performed by using the features jointly identified by the magnetic coding sequence 3 and the feature coding sequence 4, resulting in a better anti-counterfeiting effect.

[0060] Example 5

[0061] like Figure 5 As shown, the difference between this embodiment and embodiment four is that this embodiment only has one window 2. The magnetic coding sequence of the area of ​​window 2 includes eight identical rectangular magnetic codes, which are arranged in pairs with uniform spacing. In addition, this embodiment also includes an embedded area with a feature coding sequence 4. There are two feature coding sequences 4, which are respectively set above and below window 2. The feature coding sequence 4 includes magnetic features and / or fluorescent features.

[0062] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
