[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.

[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-resistant additive according to 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;

At this time, the personalized printed anti-counterfeiting mark is damaged, and the customized characters / patterns of the partial release pattern layer are also left on the card, that is, the traces of the anti-counterfeiting mark being uncovered are left, so it has the characteristics of being damaged as soon as it is uncovered and being revealed as soon as it is uncovered, and can achieve the effect of anti-uncovering and anti-transfer.

[0027] 3. The personalized printed anti-counterfeiting label of the present invention has an obvious 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 printing 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 arranged 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 bearing layer 1, and the material of the ink absorbing layer 8 is obtained by mixing fumed aluminum oxide, fumed silicon dioxide and polymer resin;

[0034] The local release pattern layer 2 is arranged 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, and part of it covers the bottom surface of the partial release pattern layer, and the rest of it covers the bottom surface of the carrier layer. Through vacuum coating technology, aluminum is melted and vaporized by electron beam heating, and the optical structure layer 3 is formed by evaporation under vacuum conditions above 10Mpa;

[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 a defoaming agent, a leveling agent and a mold-resistant auxiliary agent are added; 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 bearing layer is a PET biaxially stretched film and a transparent film with a thickness of 30 μm.

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

[0040] Taking the card anti-counterfeiting of large-scale activities as an example, the parts of the anti-counterfeiting mark other than the personalized information layer can be pre-produced in batches, and then the personalized information layer can be directly printed on the top surface of the ink absorption layer using an inkjet printer or UV printer at the event site to obtain a personalized printed anti-counterfeiting mark. Then tear off the base paper layer, and use the adhesive layer to affix the personalized printed anti-counterfeiting mark to the card. When an external force is used to uncover or peel off the personalized printed anti-counterfeiting mark, the presence of the local release pattern layer reduces the bonding force between the bearing layer and the optical structure layer, and the bearing layer will be separated from the local release pattern layer under the action of the external force, and other parts such as the holographic pattern layer will also be peeled off together with the bearing layer, while the part below the position of the local release pattern layer will still be bonded to the document. At this time, the personalized printed anti-counterfeiting mark is damaged, and the customized characters / patterns of the local release pattern layer are also left on the card, that is, the traces of the anti-counterfeiting mark being uncovered are left. Therefore, the personalized printed anti-counterfeiting mark of this embodiment has the characteristics of being damaged and appearing as soon as it is uncovered, and the effect of anti-uncovering and anti-transfer can be achieved.

[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, and 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 with an optical holographic pattern and an anti-uncovering effect as described in Embodiment 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 set characters and / or patterns is prepared, and then the printing plate is used to print the set characters and / or patterns at a local position on the bottom surface of the carrier layer using polyethylene wax as a medium to form a local release pattern layer;

[0047] S4, making a molded structure layer: dissolving acrylic resin in butanone solvent, the weight ratio of acrylic resin to butanone solvent is 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 acrylic resin and butanone solvent, and then coating the obtained mixture 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 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 structure layer, ensuring that the nickel plate is in close contact with the bottom surface of the molded structure layer; then using a stamping machine to heat the nickel plate to 120° C., applying a proper amount of pressure, ensuring that the pressure is uniform, and lasting for more than 10 seconds to ensure that the pattern is completely transferred to the molded structure layer; then curing the molded structure layer (ultraviolet irradiation, thermal curing, etc.), at this time, the bottom surface of the molded structure layer forms a holographic pattern layer with laser holographic information;

[0050] S6, coating an adhesive layer: 40% polyurethane resin, 35% ethyl acetate, 15% thickener, 6% filler and 4% leveling agent are mixed according to mass percentage to prepare a self-adhesive adhesive, and the self-adhesive adhesive is coated on the bottom surface of the holographic pattern layer by roller coating to form an adhesive layer, and then the top surface of the base paper layer and the bottom surface of the adhesive layer are combined;

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

[0054] It should be noted that fumed alumina is an ultrafine powder with a high specific surface area. It is mainly synthesized by the gas phase method, and absorbs water-based ink quickly. The high ink absorption makes the printed color full. Fumed silica is an inorganic chemical material, synthesized by gas phase reaction, and is an ultrafine white powder.
