Problems solved by technology

However, the optical change effect of the label is only formed by fixed magnetism, and the optical change form is relatively simple. With the development of science and technology, some criminals have begun to try to counterfeit it, and further improving its anti-counterfeiting strength and difficulty of counterfeiting has become an urgent solution technical issues
In addition, the molded information layer of the label can only present a single silver color, and cannot present a colorful effect

Embodiment 1

[0056] Such as figure 1 As shown, the magnetic optically variable anti-counterfeiting effect holographic anti-counterfeiting label includes a magnetic optically variable anti-counterfeiting layer 1, a protective layer 2, a printing layer 3, a plastic film layer 4, a laser aluminized coating 5, Molded information layer 6, aluminum layer 7 and glue layer 8;

[0057] Wherein, the magnetic optically variable anti-counterfeiting layer 1 is printed with magnetic ink, and a dynamic optically variable effect of depth of field is formed by magnetization and photocuring. The magnetic optically variable anti-counterfeiting layer 1 is printed with magnetic ink doped with invisible anti-counterfeiting ink, and the invisible anti-counterfeiting ink is light point display ink.

[0058] The protective layer 2 is a UV varnish protective layer.

[0059] The printing layer 3 contains variable information (two-dimensional code).

[0060] The laser aluminized coating 5 is a permanent laser alum...

Embodiment 2

[0073] Such as figure 2 As shown, the magnetic optically variable anti-counterfeiting effect holographic anti-counterfeiting label includes a magnetic optically variable anti-counterfeiting layer 1, a protective layer 2, a printing layer 3, a plastic film layer 4, a laser aluminized coating 5, Molded information layer 6, aluminum layer 7 and glue layer 8;

[0074] Wherein, the magnetic optically variable anti-counterfeiting layer 1 is printed with magnetic ink, and a dynamic optically variable effect of depth of field is formed by magnetization and photocuring. The magnetic optically variable anti-counterfeiting layer 1 is printed with magnetic ink doped with invisible anti-counterfeiting ink, and the invisible anti-counterfeiting ink is voice ink. The magnetic optically variable anti-counterfeiting layer 1 is divided into a graphic area 1.1 and an optically variable area 1.2.

[0075] The protective layer 2 is a PET precoat film.

[0076] The printing layer 3 contains gra...

Embodiment 3

[0091] The structure and preparation method of the label are the same as in Example 2.

[0092] The difference is: step 7) specifically: after printing the magnetic ink on the protective layer 2 through a screen printing machine, use a bar magnet to fix the magnetism, and after the magnetic ink reaches the position of the UV-LED light, use UV light in the graphic area 1.1 - The LED parallel light is turned on and irradiated, and the irradiation time is 2s, so that the graphic area 1.1 is solidified, and the fixed magnetic graphic area 1.1 forms a dynamic three-dimensional beam effect, and other areas are not cured. After the UV-LED light is turned off, the magnetic ink moves to the fixed position. In the magnetic area, the ring magnet is used to make the pigments in the uncured magnetic ink be oriented and distributed. After UV light curing, a magnetic dynamic optical variable effect area is formed, that is, the optical variable area 1.2. The effect of the anti-counterfeiting ...

Abstract

The invention relates to an anti-counterfeit label, in particular to a holographic anti-counterfeit label with a magnetic optical variable anti-counterfeit effect and a preparation method thereof. The holographic anti-counterfeit label with the magnetic optically variable anti-counterfeit effect comprises a magnetic optically variable anti-counterfeit layer, a protective layer, a printing layer, a plastic film layer, a laser aluminized coating, a mould pressing information layer, an aluminized layer and a glue layer which are sequentially arranged from top to bottom; the magnetic optically variable anti-counterfeiting layer is printed by adopting magnetic ink, and a depth-of-field dynamic optically variable effect is formed through fixed magnetism and photocuring. The anti-counterfeit label is gorgeous in color, unique in light changing effect, more in contained anti-counterfeit information, capable of achieving multiple anti-counterfeit, simple in identification, large in counterfeit difficulty and good in anti-counterfeit effect, and further has the function that the label is not prone to being transferred and used for the second time; the preparation method is scientific, reasonable, simple and easy to implement.

Description

technical field [0001] The invention relates to an anti-counterfeiting label, in particular to a holographic anti-counterfeiting label with a magnetic optical variable anti-counterfeiting effect and a preparation method thereof. Background technique [0002] With the continuous development of the economy, the number of counterfeit and shoddy products is increasing, making the anti-counterfeiting of products more and more important. Anti-counterfeiting. [0003] Chinese patent CN 211787899 U announces a holographic anti-counterfeiting label with 3D light-changing effect. The glue layer, the printing layer, the second plastic film layer, the release layer, the molded information layer, the aluminum plating layer and the second glue layer, the 3D light-changing effect layer is printed with magnetic ink, and the 3D light-changing effect is formed through fixed magnetism; The label can be peeled off and is divided into a peeling part and a bottom part. When peeling off, the rel...
