Technical Field

[0001] This utility model belongs to the field of anti-counterfeiting label technology, and in particular relates to an anti-counterfeiting label with a dotted concave-convex structure. Background Technology

[0002] With the rapid development of the commodity market, the problem of counterfeit and shoddy products has become increasingly serious. Traditional anti-counterfeiting technologies (such as barcodes and QR codes) have gradually revealed their defects of being easy to copy and imitate, making it difficult to meet the needs of modern commodity anti-counterfeiting.

[0003] Traditional optical anti-counterfeiting labels have limited information carrying capacity, making it difficult to meet diverse anti-counterfeiting needs. There is an urgent need for a new type of anti-counterfeiting label that combines high anti-counterfeiting performance, low cost, and large information capacity.

[0004] Therefore, developing an anti-counterfeiting label with higher anti-counterfeiting performance and that is difficult to replicate has become an important research direction in the current technology field. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-counterfeiting label with a dotted embossed structure in order to solve the common problems of anti-counterfeiting labels being easy to copy and counterfeit, and having limited information carrying capacity.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a substrate layer, on which a dotted uneven structure layer is provided, the dotted uneven structure layer is composed of multiple protruding and recessed dotted structures, a protective layer is provided on the dotted uneven structure layer, the protruding and recessed dotted structures in the dotted uneven structure layer are arranged in a matrix, a ring, or a spiral, the dotted structures in the dotted uneven structure layer are recessed and protruding structures with light reflection and refraction characteristics to form a holographic effect and a rainbow effect, and an adhesive layer is provided below the substrate layer.

[0007] Furthermore, the dot-shaped concave-convex structure in the dot-shaped concave-convex structure layer is circular, elliptical, triangular, square, or hexagonal. The cross-sectional shape of the protrusions and depressions in the dot-shaped concave-convex structure layer is trapezoidal, and the edges of the protrusions and depressions are at least one of smooth, serrated, or wavy.

[0008] Furthermore, the density of the dotted structures in the dotted uneven structure layer varies in different regions, forming specific patterns and information.

[0009] Furthermore, the dotted structure surface in the dotted uneven structure layer is coated with a fluorescent coating.

[0010] Furthermore, the dotted structure in the dotted uneven structure layer is arranged to encode specific information, such as the serial number and production date.

[0011] Furthermore, the diameter of the protrusions and depressions in the dotted uneven structure layer ranges from 0.1 mm to 1 mm, and the height or depth of the protrusions and depressions in the dotted uneven structure layer ranges from 0.05 mm to 0.5 mm.

[0012] Furthermore, both the substrate layer and the protective layer are made of semi-transparent materials.

[0013] Furthermore, the adhesive layer is a pressure-sensitive adhesive.

[0014] Furthermore, the anti-counterfeiting label also includes a printing layer disposed on the protective layer, the printing layer containing anti-counterfeiting information.

[0015] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0016] 1. In this utility model, by setting a dotted concave-convex structure layer, the light reflection and refraction characteristics are utilized to form a holographic effect and a rainbow effect, which significantly improves the visual recognition and anti-counterfeiting performance of the anti-counterfeiting label. Moreover, this unique optical effect is difficult to replicate, effectively preventing counterfeiting.

[0017] 2. In this utility model, the diverse shapes and arrangements of the dotted concave-convex structure (such as matrix, ring, and spiral arrangements), as well as the density variations in different areas, enable the anti-counterfeiting label to carry more information and form specific patterns, further enhancing the anti-counterfeiting function.

[0018] 3. In this utility model, by coating the surface of the dotted structure with a fluorescent coating, this solution can display different anti-counterfeiting effects under both conventional light and ultraviolet light, which increases the concealment and detection means of the anti-counterfeiting label and improves the reliability of anti-counterfeiting.

[0019] 4. In this utility model, the arrangement of the dot-like structure encodes specific information (such as serial number and production date), which enables the anti-counterfeiting label to not only have visual anti-counterfeiting function, but also to read the encoded information through specific devices, thereby realizing dual anti-counterfeiting verification and improving the practicality and security of the anti-counterfeiting label.
