[0020] Self-erasing ink is a special ink that becomes colorless when exposed to certain environmental factors. This property gives it broad application prospects in the anti-counterfeiting field. Fragile paper is a special paper that is fragile and will break once it is affected by external force. It can be used as an effective physical anti-counterfeiting method.

[0021] Therefore, the utility model combines the chemical anti-counterfeiting properties of self-erasing ink and the physical anti-counterfeiting properties of fragile paper to design a dual anti-counterfeiting label to improve the safety and reliability of the product. The label can not only improve the safety and reliability of the product, but also reduce the label cost and enhance the anti-counterfeiting effect. Through the design and application of this patent, the dual anti-counterfeiting label based on self-erasing ink and fragile paper will be able to play a more important role in protecting product safety and combating counterfeiting and shoddy products.

[0022] For details, please refer to Figure 1 and Figure 2 The utility model proposes a degradable double anti-counterfeiting label based on self-erasable ink and shatter-proof paper. The preferred embodiment of the degradable double anti-counterfeiting label based on self-erasable ink and shatter-proof paper of the utility model includes: an electrochromic structure layer 10, a label surface paper layer 20, an adhesive layer 30 and a shatter-proof paper layer 40 arranged in sequence from top to bottom.

[0023] In this embodiment, the electrochromic structure layer 10 constitutes the first anti-counterfeiting design. The electrochromic structure layer 10 uses the label paper as a substrate, and is printed with an electrode layer 101, an electrolyte layer 102, a color-changing layer 103 and a pattern layer 104 from bottom to top.

[0024] The electrode layer 101 is made of carbon paste or silver paste.

[0025] The electrolyte layer 102 is a UV-curable gel electrolyte.

[0026] The pattern layer 104 is a pattern printed with self-erasable ink.

[0027] The preparation method of the electrochromic structure layer 10 is as follows:

[0028] The electrochromic label is obtained by screen printing layer by layer: with the label paper as the substrate, the electrode material (electrode layer 101, such as carbon paste / silver paste, etc.), UV-curable gel electrolyte (electrolyte layer 102), electrochromic conductive ink (color-changing layer 103) and the pattern printed with self-erasable ink (pattern layer 104) are printed in sequence.

[0029] First, anti-counterfeiting verification is performed through electrochromic technology. The driving power supply provides voltage to the label, so that the label changes color, thereby realizing anti-counterfeiting verification. Second, self-erasing ink is used as the pattern layer 104 of the label. By utilizing the characteristics of self-erasing ink, an anti-counterfeiting mark, such as a verification code or a product serial number, is formed on the label. When the label is affected by environmental factors, the anti-counterfeiting mark disappears and the label becomes colorless, and this process is irreversible.

[0030] This embodiment uses electrochromic technology to achieve the anti-counterfeiting goal: electrochromic technology can generate variable colors or patterns, and this change process is difficult to imitate or copy, which improves the security and reliability of anti-counterfeiting. At the same time, it increases the interest of the label to a certain extent.

[0031] In this embodiment, the preparation method of the self-erasing ink is as follows: alkaline indicators (such as thymol blue, phenolphthalein, alizarin yellow R, etc.), alkaline solutions (such as NaOH, KOH, etc.), binders (alcohol-soluble acrylic resins), additives, etc. are mixed in a solvent (alcohols) in proportion, and the pH of the solution is adjusted to be maintained between 8 and 14. Among them, the mass fraction of the alkaline indicator is 0.5wt% to 3.0wt%, the mass fraction of the alkaline solution is 0.02wt% to 0.5wt%, and the binder is 30wt% to 85wt%. The self-erasing ink can react with air to produce irreversible color disappearance.

[0032] The present embodiment uses irreversible self-erasable ink as the printing layer of the label, which has the following effects: (1) the self-erasable ink will lose its color under the action of air and cannot be restored, which can effectively prevent the label from being tampered with or copied, thereby improving the anti-counterfeiting effect; (2) due to the irreversible characteristics of the self-erasable ink, the original appearance of the label cannot be restored by conventional means, thereby increasing the difficulty and cost of counterfeiting; (3) improving the recyclability of the label paper.

[0033] In this embodiment, fragile paper is used as the bottom paper layer of the degradable dual anti-counterfeiting label based on self-erasable ink and fragile paper, forming the second anti-counterfeiting design. This embodiment uses the characteristics of fragile paper. When the label is pasted on the surface of the product or outer packaging, the fragile paper will break when it is peeled off and cannot be restored, thereby forming a unique feature that is difficult to copy, which can effectively prevent the label from being tampered with or replaced, and improve the anti-counterfeiting effect. At the same time, QR code, RFID and other technologies can be used to store product information and other sensitive data in the label, increasing the anti-counterfeiting ability and security of the label.

[0034] Furthermore, in this embodiment, the label surface paper is made of water-soluble paper, and the adhesive layer 30 is made of water-soluble glue.

[0035] In this embodiment, the label face paper printing layer uses self-decolorizing ink. After the ink is decolorized, the label face paper can be recycled. When the label life cycle ends, the water-soluble face paper can be directly decomposed in water, avoiding unnecessary burden on the environment and facilitating degradation and environmental protection.

[0036] The beneficial effects of the degradable double anti-counterfeiting label based on self-erasable ink and shatter-proof paper of the utility model are:

[0037] The utility model adopts the above technical scheme, including: an electrochromic structure layer, a label surface paper layer, an adhesive layer and a fragile paper layer arranged in sequence from top to bottom, and adopts an electrochromic structure layer and a fragile paper layer to form a double anti-counterfeiting design, which can improve the safety and reliability of the product, reduce the label cost, enhance the anti-counterfeiting effect, and play a more important role in protecting product safety and combating counterfeiting and shoddy products.

[0038] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
