Description

Technical Field

[0001] The present invention relates to the technical field of anti-counterfeiting labels, and in particular to a personalized printed anti-counterfeiting label with an optical holographic pattern and an anti-revealing effect. Background Art

[0002] Existing anti-counterfeiting labels used in logistics, anti-theft sealing labels, and seals utilize anti-tear technology to prevent unauthorized removal, removal, and re-application. Once removed, colored text appears on the substrate. Current labels typically consist of a colored, blank plastic strip. These can be created using various surface materials, including matte silver, bright silver, and gleaming silver. However, these production methods require large-scale printing equipment, making customization impossible. Printable labels based on paper substrates lack the ability to achieve optical holographic effects, making them easily counterfeitable and lacking in anti-counterfeiting capabilities. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention aims to provide a personalized printed anti-counterfeiting label with an optical holographic pattern and an anti-uncovering effect.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A personalized printed anti-counterfeiting label with an optical holographic pattern and an anti-uncovering effect, comprising a carrier layer, a partial release pattern layer, an optical structure layer, a molded structure layer, a holographic pattern layer, an adhesive layer, a base paper layer, an ink absorption layer, and a personalized information layer;

[0006] The personalized information layer is printed on the top surface of the ink absorption layer;

[0007] The ink absorbing layer is arranged on the top surface of the supporting layer, and the material of the ink absorbing layer is obtained by mixing fumed alumina, fumed silica and polymer resin;

[0008] The local release pattern layer is provided at a local position on the bottom surface of the carrier layer, and is formed by printing on the bottom surface of the carrier layer using a printing plate having set characters and / or patterns and polyethylene wax as a medium;

[0009] The optical structure layer is located below the partial release pattern layer, partially covering the bottom surface of the partial release pattern layer, and the rest covering the bottom surface of the carrier layer; the optical structure layer is formed by evaporation under vacuum conditions of more than 10 MPa using vacuum coating technology to melt and vaporize aluminum by electron beam heating;

[0010] The molded structure layer is arranged on the bottom surface of the optical structure layer; the material of the molded structure layer is obtained by dissolving acrylic resin in butanone solvent, and is added with a defoaming agent, a leveling agent and a mold-resistant auxiliary agent; the holographic pattern layer is arranged on the bottom surface of the molded structure layer;

[0011] The adhesive layer is arranged on the bottom surface of the holographic pattern layer, and the base paper layer is arranged on the bottom surface of the adhesive layer.

[0012] Furthermore, the supporting layer is a PET biaxially oriented transparent film with a thickness of 30 μm.

[0013] Furthermore, the base paper layer is made of glassine base paper or silicone oil paper.

[0014] Furthermore, the thickness of the optical structure layer is greater than 0.04 μm.

[0015] The present invention also provides a method for preparing the personalized printed anti-counterfeiting mark having an optical holographic pattern and an anti-uncovering effect, comprising the following steps:

[0016] S1, cutting to obtain the bearing layer;

[0017] S2. Printing a local release pattern layer: First, a printing plate with predetermined characters and / or patterns is prepared. Then, the predetermined characters and / or patterns are printed on a local location on the bottom surface of the carrier layer using the printing plate with polyethylene wax as a medium to form a local release pattern layer.

[0018] S3. Fabricating an optical structure layer: Using vacuum coating technology, aluminum is melted and vaporized by electron beam heating. Vapor deposition is performed on the bottom surface of the carrier layer on which the partial release pattern layer is printed under vacuum conditions of 10 MPa or more to form an optical structure layer. The optical structure layer partially covers the bottom surface of the partial release pattern layer, and the remaining portion covers the bottom surface of the carrier layer.

[0019] S4. Making a molded structure layer: dissolving an acrylic resin in a butanone solvent, wherein the weight ratio of the acrylic resin to the butanone solvent is 1:1.7, and adding 0.2%-0.4% of a defoamer, 1.2%-1.5% of a leveling agent, and 2.6%-2.9% of a mold resistance additive based on the total weight of the acrylic resin and the butanone solvent, and then coating the obtained mixture to cover the bottom surface of the optical structure layer to form a molded structure layer;

[0020] S5. Making a holographic pattern layer: Using photolithography technology to make a nickel plate with a set pattern having interference and diffraction effects; placing the nickel plate on the bottom surface of the molded structural layer, ensuring that the nickel plate is in close contact with the bottom surface of the molded structural layer; then using a stamping machine to heat the nickel plate to 120°C-130°C, applying appropriate pressure, ensuring that the pressure is uniform, and maintaining it for more than 10 seconds to ensure that the pattern is completely transferred to the molded structural layer; then curing the molded structural layer, at this time, the bottom surface of the molded structural layer forms a holographic pattern layer with laser holographic information;

[0021] S6. Applying an adhesive layer: Mixing 40% polyurethane resin, 35% ethyl acetate, 15% thickener, 6%-8% filler, and 2%-4% leveling agent by mass to form a self-adhesive adhesive, applying the self-adhesive adhesive to the bottom surface of the holographic pattern layer by roller coating to form an adhesive layer, and then bonding the top surface of the base paper layer to the bottom surface of the adhesive layer;

[0022] S7. Preparing an ink absorbing layer: Mixing, by weight, 8%-10% fumed alumina, 20%-25% polymer water-swellable resin, 12%-15% fumed silica, 27%-31% binder, 2.5%-2.9% dispersant, 0.3%-0.8% defoamer, and the remainder ethanol to form a coating; uniformly applying the coating to the top surface of the carrier layer by roller coating to form an ink absorbing layer on the top surface of the carrier layer;

[0023] S8. Personalized information layer: Print personalized information and colorless fluorescent pattern on the top surface of the ink absorption layer using an inkjet printer or a UV printer to form a personalized information layer, thereby obtaining a personalized printed anti-counterfeiting mark having an optical holographic pattern and an anti-uncovering effect.

[0024] The beneficial effects of the present invention are:

[0025] 1. The personalized printed anti-counterfeiting label of the present invention has printable performance, supports personalized printing information, is more flexible to use, can be applied to various occasions, and meets different usage needs. In addition, the anti-counterfeiting label of the present invention also has a holographic pattern and strong anti-counterfeiting performance, so the present invention can realize personalized printing of high-level anti-counterfeiting labels.

[0026] 2. When an external force is applied to remove or peel the personalized printed anti-counterfeiting label of the present invention, the carrier layer separates from the partial release pattern layer under the force, and the holographic pattern layer and other portions are also peeled off along with the carrier layer. However, the portion below the partial release pattern layer remains adhered to the document. This damages the personalized printed anti-counterfeiting label, and the customized characters / pattern of the partial release pattern layer remain on the card, leaving a trace of the anti-counterfeiting label being removed. Therefore, the personalized printed anti-counterfeiting label is both instantly visible and instantly recognizable upon removal, achieving anti-tampering and anti-transfer properties.

[0027] 3. The personalized printed anti-counterfeiting label of the present invention has a distinct metallic luster and an embedded holographic pattern, and on-site security personnel can quickly and accurately identify the label by visual inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 Schematic diagram of the composite structure of the personalized anti-counterfeiting mark in Example 1 of the present invention. DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0030] Example 1

[0031] This embodiment provides a personalized printed anti-counterfeiting mark with an optical holographic pattern and an anti-uncovering effect, such as Figure 1 As shown, it includes a carrier layer 1, a local release pattern layer 2, an optical structure layer 3, a molded structure layer 4, a holographic pattern layer 5, an adhesive layer 6, a backing paper layer 7, an ink absorption layer 8 and a personalized information layer 9;

[0032] The personalized information layer 9 is provided on the top surface of the ink absorption layer 8 by printing;

[0033] The ink absorbing layer 8 is arranged on the top surface of the carrier layer 1, and the material of the ink absorbing layer 8 is obtained by mixing fumed alumina, fumed silica and polymer resin;

[0034] The local release pattern layer 2 is provided at a local position on the bottom surface of the carrier layer 1 and is formed by printing on the bottom surface of the carrier layer 1 using a printing plate with set characters and / or patterns and polyethylene wax as a medium;

[0035] The optical structure layer 3 is located below the partial release pattern layer 2, partially covering the bottom surface of the partial release pattern layer and the rest covering the bottom surface of the carrier layer. The optical structure layer 3 is formed by vacuum deposition under vacuum conditions of 10 MPa or higher, using electron beam heating to melt and vaporize aluminum.

[0036] The molded structure layer 4 is arranged on the bottom surface of the optical structure layer 3; the material of the molded structure layer 4 is obtained by dissolving acrylic resin in butanone solvent, and adding a defoaming agent, a leveling agent and a mold-resistant auxiliary agent; the holographic pattern layer 5 is arranged on the bottom surface of the molded structure layer 4;

[0037] The adhesive layer 6 is disposed on the bottom surface of the holographic pattern layer 5 , and the base paper layer 7 is disposed on the bottom surface of the adhesive layer 6 .

[0038] Furthermore, the supporting layer is a PET biaxially oriented film and a transparent film with a thickness of 30 μm.

[0039] Furthermore, the bottom paper layer is made of 80g / ㎡ thick glassine bottom paper or silicone oil paper with the same performance.

[0040] Taking the anti-counterfeiting measures for large-scale events as an example, the anti-counterfeiting label, excluding the personalized information layer, can be pre-produced in bulk. Then, at the event, the personalized information layer can be printed directly on top of the ink-absorbing layer using an inkjet printer or UV printer, resulting in a personalized printed anti-counterfeiting label. The backing paper layer is then removed, and the personalized printed anti-counterfeiting label is affixed to the card using the adhesive layer. When an external force is applied to remove or peel off the personalized printed anti-counterfeiting label, the presence of the partial release pattern layer reduces the bonding strength between the carrier layer and the optical structure layer. The carrier layer separates from the partial release pattern layer under the external force, and other portions, such as the holographic pattern layer, are also peeled off along with the carrier layer. However, the portion below the partial release pattern layer remains adhered to the card. This damages the personalized printed anti-counterfeiting label, and the customized characters / patterns of the partial release pattern layer remain on the card, leaving a trace of the removal of the anti-counterfeiting label. Therefore, the personalized printed anti-counterfeiting label of this embodiment is both instantly destructible and instantly recognizable upon removal, achieving anti-tear and anti-transfer properties.

[0041] It should also be noted that the personalized printed anti-counterfeiting label has an obvious metallic luster and an embedded holographic pattern due to the optical structure layer and the holographic pattern layer, so on-site security personnel can quickly and accurately identify the label by visual inspection.

[0042] Example 2

[0043] This embodiment provides a method for preparing the personalized printed anti-counterfeiting mark having an optical holographic pattern and an anti-uncovering effect as described in Example 1, comprising the following steps:

[0044] S1, cutting to obtain the bearing layer;

[0045] S2. Printing a local release pattern layer: First, a printing plate with predetermined characters and / or patterns is prepared. Then, the predetermined characters and / or patterns are printed on a local location on the bottom surface of the carrier layer using the printing plate with polyethylene wax as a medium to form a local release pattern layer.

[0046] S3. Fabricating the optical structure layer: Using vacuum coating technology, aluminum is melted and vaporized by electron beam heating, and then vapor-deposited on the bottom surface of the carrier layer provided with the partial release pattern layer under vacuum conditions of 10 MPa or more, with a coating thickness of 0.04 μm or more, so that the optical structure layer partially covers the bottom surface of the partial release pattern layer, and the remaining portion covers the bottom surface of the carrier layer;

[0047] S4. Making a molded structure layer: dissolving acrylic resin in butanone solvent, with a weight ratio of acrylic resin to butanone solvent of 1:1.7, and adding 0.2% defoamer, 1.2% leveling agent, and 2.6% mold resistance additive according to the percentage of the total weight of the acrylic resin and butanone solvent. Then, the obtained mixture is flow-coated to cover the bottom surface of the optical structure layer 3 to form a molded structure layer with a thickness of 2 μm;

[0048] In this embodiment, the defoaming agent is dimethyl silicone, the leveling agent is polybutyl acrylate, and the anti-molding auxiliary agent is polytetrafluoroethylene (PTFE) powder.

[0049] S5. Making a holographic pattern layer: Using photolithography technology, a nickel plate with a predetermined pattern having interference and diffraction effects is made; the nickel plate is placed on the bottom surface of the molded structural layer, ensuring close contact between the nickel plate and the bottom surface of the molded structural layer; then, a stamping machine is used to heat the nickel plate to 120° C., and an appropriate amount of pressure is applied, ensuring uniform pressure for more than 10 seconds to ensure that the pattern is completely transferred to the molded structural layer; then, the molded structural layer is cured (by ultraviolet irradiation, thermal curing, etc.), at which point, a holographic pattern layer having laser holographic information is formed on the bottom surface of the molded structural layer;

[0050] S6. Applying an adhesive layer: Mixing 40% polyurethane resin, 35% ethyl acetate, 15% thickener, 6% filler, and 4% leveling agent by mass to form a self-adhesive adhesive, applying the self-adhesive adhesive to the bottom surface of the holographic pattern layer by roller coating to form an adhesive layer, and then bonding the top surface of the base paper layer to the bottom surface of the adhesive layer;

[0053] In this embodiment, the binder is polyurethane emulsion, the dispersant is sodium hexametaphosphate, and the defoaming agent is polysiloxane.

[0054] It should be noted that fumed alumina is an ultrafine powder with a high specific surface area. It is primarily synthesized through a vapor phase process and absorbs water-based inks quickly and efficiently, resulting in rich, vibrant colors. Fumed silica is an inorganic chemical material synthesized through a vapor phase reaction. It is an ultrafine white powder with an extremely small particle size and a large specific surface area. It exhibits excellent thickening and thixotropic properties, which improve ink absorption.

[0055] S8.

[0056] Furthermore, the logo can be separated and removed by positioning the die-cutting machine or by using digital die-cutting.

[0057] Those skilled in the art can make various corresponding changes and modifications based on the above technical solutions and concepts, and all of these changes and modifications should be included in the scope of protection of the claims of the present invention.
