[0022] The utility model will be further described below in conjunction with the accompanying drawings.

[0023] See also Figures 1 to 4 The utility model of the hot stamping anti-counterfeiting label comprises a base paper 4 and a label body, and the label body comprises an adhesive layer 3, a substrate layer 2 and a hot stamping layer 1 from bottom to top.

[0024] The substrate 4 is made of glassine paper or release film; if the substrate is glassine paper, a 60-80g single-sided glassine release paper is used.

[0025] The thickness of the adhesive layer 3 is 10-20 μm, and the adhesive layer 3 is made of environmentally friendly acrylic latex, hot melt adhesive or oil adhesive.

[0026] The substrate layer 2 is made of self-adhesive paper, coated paper, fragile paper or printable PET or PVC; a plurality of anti-tear lines 20 are arranged on the edge of the substrate layer 2 to prevent the label body from being peeled off and used for other purposes.

[0027] The hot stamping layer 1 includes a protective film layer 11, an information pattern layer 12, an aluminum plating layer 13 and an adhesive layer 14 arranged in sequence from top to bottom. The hot stamping layer 1 is bonded to the upper surface of the substrate layer 2 through the adhesive layer 14 after die-cutting; the protective film layer 11 is made of a transparent biaxially oriented polypropylene film, which can protect the surface of the label body;

[0028] The information pattern layer 12 plays the role of carrying the molded information. The material of the information pattern layer 12 is a thermoplastic resin, which is prepared by mixing polyacrylic resin and polyurethane resin. The surface of the material is coated with 4-6U transparent solvent ink by a micro-concave coating machine. It is required to be high temperature resistant, non-sticky, and have a long thermoplastic temperature range. After the grating holographic texture is molded by the molding machine, it has a strong bonding force with the aluminum plating layer 13 and can be used to display the company's logo and other brand patterns, product information and other beautification patterns. The information pattern layer 12 contains five anti-counterfeiting effect display layers, namely, a diffraction black effect layer 121, a dynamic matte effect layer 122, a micro-text layer 123, a relief effect layer 124 and a lens effect layer 125.

[0029] The diffraction black effect layer 121 presents a dark contrast to the design elements at almost all viewing positions; when tilted around the horizontal axis and viewed at an inclined angle, the design elements appear bright blue-green; the diffraction black effect layer 121 adopts high-frequency grating technology, using optical micro-nano grating stripes to arrange, and an optical phenomenon presented by a texture with an angle of 40 to 60 degrees; when the label is viewed from the front or the label is rotated 90 degrees to view the character pattern vertically, a high-frequency grating will appear, achieving a black visual effect from the front and an adjustable color effect such as blue or green at 45 degrees;

[0030] The dynamic matte effect layer 122 is a frosted texture with a surface roughness Ra=0.10-0.30 μm. When the back of the information pattern layer 12 is plated with aluminum (aluminum-plated layer 13), a dynamic matte silver effect can be achieved; if the back of the information pattern layer 12 is plated with other colors, a dynamic matte effect can also be presented; by adjusting the surface roughness Ra of the frosted texture, different matte effects can be presented;

[0031] The micro-text layer 123 is engraved by a photolithography machine, and the line thickness of the characters is 3 to 10 microns, and the height of the characters is 50 to 100 microns; the characters in the micro-text layer 123 are invisible to the naked eye and can only be seen under a 100-fold magnifying glass;

[0032] The relief effect layer 124 is realized by a specially designed diffraction structure, which gives the design element a unique sense of depth and movement; it seems to protrude from the plane and feels good to the touch, but is actually completely flat; the image and text present a depth of field effect by applying a photolithography algorithm, and the texture with an angle of 20 to 30 degrees by using an optical micro-nano grating stripe arrangement can achieve an adjustable effect such as gold or yellow on the front visual effect;

[0033] The lens effect layer 125 adds a lens effect, whereby a bright beam of light appears to converge on a virtual point under the design surface and radiate from the virtual point; when viewed with a bright light, the beam of light can be seen as the color of the spectrum; a high-gloss mirror texture is used, and when the back side is aluminum-plated (aluminum-plated layer 13), a lens effect can be achieved;

[0034] The diffraction black effect layer 121, the dynamic matte silver effect layer 122, the micro-text layer 123, the relief effect layer 124 and the lens effect layer 125 are randomly stacked or tiled;

[0035] The five anti-counterfeiting effect display layers in the information pattern layer 12 use a nickel plate mold (the nickel plate mold is made by pre-making a grating structure with embossed concave-convex grooves on the surface, and then using special equipment to burn the texture structure into a nickel plate mold). The nickel plate mold is wrapped on a molding machine, and the grating texture image on the nickel plate mold is pressed onto the information pattern layer 12 (thermoplastic resin) at a temperature of 120 to 200° and a pressure of 5 to 10 kg. After cooling, demolding, and winding in the molding machine, the aluminum layer 13 is electroplated with aluminum. The grating structure of the molded hologram is fine, with a spatial frequency of 1000 to 1500 lines / mm and a depth of several microns to tens of microns. The specific depth depends on the grating production process used and the grating texture effect to be achieved. Generally, the greater the depth of the grating structure, the better the resolution and three-dimensional sense of the anti-counterfeiting hologram, but it will also increase the difficulty and cost of production.

[0036] The aluminum plating layer 13 is formed by vacuum high-temperature evaporation, cooling, and deposition of metal aluminum, and has a thickness of 0.025-0.5 μm. Its main function is to reflect light, so that the information pattern layer 12 presents a metallic luster.

[0037] The adhesive layer 14 is mainly made of environmentally friendly acrylic latex, hot melt adhesive or oil adhesive, with a thickness of 1 to 2 μm. Its function is to bond the hot stamping layer 1 to the substrate layer 2 under the action of pressure and temperature.

[0038] When the utility model is used, the hot stamping anti-counterfeiting label is peeled off from the base paper 4 through the adhesive layer 3, and then transferred to the object to be pasted (the surface of various products) under the action of pressure and temperature.

[0039] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Technicians in the relevant technical field can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
