Specific embodiments To clarify and make more understandable the above and / or other purposes, effects and features of the present utility model, preferred embodiments are explained in detail below: The purpose of the present utility model is to provide an electronic label 1 for thermal transfer printing, as shown in Fig. 1, comprising the following: a substrate material 2; a first ink layer 3, wherein one side of the first ink layer is bonded to one side of the substrate material 2; a second ink layer 4, wherein one side of the second ink layer is bonded to another side of the first ink layer 3, such that the first ink layer 3 is located between the substrate material 2 and the second ink layer 4;a third ink layer 5, wherein one side of the third ink layer is connected to the other side of the second ink layer 4, such that the second ink layer 4 is located between the first ink layer 3 and the third ink layer 5; an antenna layer 6, wherein one side of the antenna layer is connected to another side of the third ink layer 5, such that the third ink layer 5 is located between the second ink layer 4 and the antenna layer 6; and a chip 7, wherein one side of the chip is connected to another side of the antenna layer 6, such that the antenna layer 6 is located between the third ink layer 5 and the chip 7. Preferably, the thickness of the substrate material 2 is 75 µm to 100 µm, but is not limited to this, so that the electronic label 1 for thermal transfer printing is thin and light overall, has a certain degree of structural protection, and can withstand pressure or impacts. In a preferred embodiment, the thickness of the antenna layer 6 is less than or equal to 10 µm, but is not limited to this. In another preferred embodiment, the thickness of the chip 7 is 150 µm to 250 µm, but is not limited to this. In a further preferred embodiment, the thickness of the first ink layer 3, the second ink layer 4, or the third ink layer 5 is 5 µm to 30 µm, but is not limited to this. In a further preferred embodiment, the chip 7 is an RFID or NFC chip.When the chip is used for anti-counterfeiting purposes, the information pre-stored in the RFID or NFC chip is read via a mobile device and compared with the information in the database; based on the comparison result, the authenticity of the product corresponding to the electronic label 1 for thermal transfer printing can be confirmed or refuted. In particular, the design is more reliable and practical with regard to reading information and identifying counterfeits than conventional, externally attached electronic labels, since the electronic label 1 for thermal transfer printing adheres firmly to the product or the item to be labeled. Preferably, the antenna layer 6 consists of conductive ink containing silver or copper filler, but is not limited to this, in order to give the antenna layer 6 high flexibility, to enable large-area application of the antenna layer 6, to increase the efficiency of the arrangement of the antenna layer 6, or to give the antenna layer 6 a certain degree of heat resistance. In a preferred embodiment, the antenna layer 6 is formed on the third ink layer 5 by screen printing, gravure printing, inkjet printing, or flexographic printing, but is not limited to this.In a further preferred embodiment, the composition of the carrier material 2, in order to facilitate corona or plasma treatment, to ensure a certain degree of heat resistance, to adapt the surface roughness, or to provide a certain ink absorption capacity, whereby the ink adheres firmly and fading is prevented, comprises, but is not limited to, the following components: polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polyimide (PI), polycarbonate (PC), polyvinyl chloride (PVC), thermoplastic polyurethane (TPU), plant fibers, glass fibers, or ceramics. Preferably, the electronic label for thermal transfer printing further comprises: a first cover layer 8 formed between the third ink layer 5 and the antenna layer 6, which shields the antenna layer 6 and the chip 7 to reflect light, insulate against temperature, prevent softening of the antenna layer 6, or prevent thermal deformation of the antenna layer 6, as shown in Fig. 2. In a preferred embodiment, the electronic label for thermal transfer printing further comprises: a first elastic buffer layer 9 formed between the first cover layer 8 and the antenna layer 6 to provide a degree of elastic protection so that the antenna layer 6 exerts a cushioning effect under pressure without breaking or shifting or deforming due to compression.In another preferred embodiment, the electronic label for thermal transfer printing further comprises the following: an adhesive layer 10 formed between the first elastic buffer layer 9 and the antenna layer 6 to better control the process yield, ensure the ink print quality, and improve the alignment accuracy between the antenna layer 6 and the chip 7, as shown in Fig. 3. In particular, during the production of electronic labels 1 for thermal transfer printing, the layers are stacked directly one on top of the other on one side of the substrate material 2 until the stacking is complete. However, due to the large number of stacked layers, even a slight displacement of a single layer caused by movement leads to a steady increase in defects in the subsequent layers.This simultaneously impairs the accuracy of the printed image and leads to a shift in the position of chip 7, resulting in no electrical connection to the antenna layer 6, which renders the entire series of electronic labels 1 unusable for thermal transfer printing. To avoid the above problems, the first ink layer 3, the second ink layer 4, the third ink layer 5, the first cover layer 8, and the first elastic buffer layer 9 can be formed sequentially on a substrate 2. Subsequently, the chip 7, the antenna layer 6, and the adhesive layer 10 are formed sequentially on another substrate 2. Finally, the other side of the adhesive layer 10 is precisely fused to the other side of the first elastic buffer layer 9 to assemble the electronic label 1 for thermal transfer printing.It is understood that the procedure described above allows for separate checks of the ink print quality and the precision of the electrical connection. Only after confirmation that both meet the standards can the bonding process be carried out. This reduces errors and increases the production yield of the electronic label 1 for thermal transfer printing. Preferably, the electronic label for thermal transfer printing further comprises: a second cover layer 11, wherein one side of the second cover layer is connected to another side of the chip 7 to shield the chip 7 and the antenna layer 6, thus protecting both sides of the antenna layer 6 and the chip 7 and thereby achieving thermal insulation, and to prevent softening or thermal deformation of the antenna layer 6, as shown in Fig. 4.In a preferred embodiment, the electronic label for thermal transfer printing further comprises: a second elastic buffer layer 12, wherein one side of the second elastic buffer layer is connected to another side of the second cover layer 11, such that the second cover layer 11 is located between the second elastic buffer layer 12 and the chip 7 to enhance elastic protection so that the antenna layer 6 and the chip 7 provide cushioning under pressure without breaking, shifting, or deforming due to compression. In another preferred embodiment, the first cover layer 8 and the second cover layer 11 are formed by spraying white ink; and the first elastic buffer layer 9 and the second elastic buffer layer 12 are formed by spraying transparent ink, although this is not limited to the above.In a further embodiment, the electronic label for thermal transfer printing further comprises the following: a hot-melt adhesive layer 13 formed on the opposite side of the second elastic buffer layer 12, such that the second elastic buffer layer 12 is located between the hot-melt adhesive layer 13 and the second cover layer 11 to ensure adhesion so that the electronic label 1 for thermal transfer printing can be applied to a specific material or the surface of an object. In a further preferred embodiment, the hot-melt adhesive layer 13 is a coating of functional ink and can be transparent or opaque. The formation of the first ink layer 3, the second ink layer 4, and the third ink layer 5 serves to produce spray patterns with different shapes, patterns, or colors on the substrate 2 in order to increase the color or shape variety of the printed pattern. The electronic label for thermal transfer printing further comprises the following: a fourth ink layer 14, which is formed between the first ink layer 3 and the substrate 2, as shown in Fig. 5.
