Example Embodiment

[0031] The preparation method of the present invention is specifically described below in conjunction with examples.

[0032] like figure 1 As shown, the holographic anti-counterfeiting hot stamping foil can usually be composed of five layers of different materials, including a plastic carrier film 1, a separation layer 2, an information recording layer 3, a medium layer 4 and an adhesive layer 6 stacked in sequence.

[0033] like figure 2 As shown, the laser holographic anti-counterfeiting hot stamping foil containing magnetically encrypted information of the present invention is composed of six different material layers, including a plastic carrier film 1, a separation layer 2, an information recording layer 3, a dielectric layer 4, and a magnetic coating layer stacked in sequence. 5 and adhesive layer 6.

Example Embodiment

[0034] Example 1

[0035] A high-speed coater is used to uniformly coat a separation layer 2 on a 15 μm PET plastic carrier film 1 at a coating temperature of 120° C. and a speed of 80 m / min. The acrylic resin was evenly coated on the separation layer 2 to form the information recording layer 3 at a coating temperature of 90° C. and a speed of 80 m / min. On the molding machine, the laser holographic information on the metal nickel plate is transferred to the information recording layer 3, so that the information recording layer 3 is provided with the laser holographic information. The molding temperature is 150° C., and the speed is 40 m / min. In a vacuum state, silicon dioxide is plated on the surface of the information recording layer 3 to form a dielectric layer 4 with a thickness of 350 angstroms. A magnetic coating 5 is coated on the dielectric layer 4 at a coating temperature of 120° C. and a speed of 60 m / min. Ethylene-vinyl acetate copolymer resin hot-melt adhesive is ...

[0036] Example 2

[0037] A high-speed coater is used to evenly coat the separation layer 2 on the 12 μm PET plastic carrier film 1 with a coating temperature of 120° C. and a speed of 80 m / min. The acrylic resin was evenly coated on the separation layer 2 to form the information recording layer 3 at a coating temperature of 90° C. and a speed of 80 m / min. On the molding machine, the laser holographic information on the metal nickel plate is transferred to the information recording layer 3, so that the information recording layer 3 is provided with the laser holographic information. The molding temperature is 150° C., and the speed is 40 m / min. In a vacuum state, zinc sulfide is plated on the surface of the information recording layer 3 to form a dielectric layer 4 with a thickness of 350 angstroms. A magnetic coating 5 is coated on the dielectric layer 4 at a coating temperature of 120° C. and a speed of 60 m / min. Polyethylene and ethylene copolymer hot-melt adhesives are c...

Abstract

The invention provides a laser holographic anti-counterfeiting stamping foil containing magnetic encryption information and a preparation method thereof. A separation layer, an information recording layer and a medium layer are arranged in turn between a plastic carrier film layer and a bonding glue layer. The laser holographic anti-counterfeiting stamping foil is characterized in that a magnetic coat is also arranged between the medium layer and the bonding glue layer; moreover, a magnetic material is not printed on the surface of the stamping foil but coated on the medium layer; thus, the magnetic material cannot cover holographic patterns, and magnetic information writing and reading can be carried out through an instrument; therefore, the stamping foil not only contains holographic anti-counterfeiting information, but also has the function of magnetic encryption information anti-counterfeiting protection to obtain the effect of multiple anti counterfeiting.

Description

technical field [0001] The invention belongs to comprehensive anti-counterfeiting technology, and specifically discloses a laser holographic anti-counterfeiting hot stamping foil containing magnetic encryption information and a preparation method thereof. Background technique [0002] Counterfeit and shoddy products are a global problem. Since the development of the socialist market economy in our country, we have been fighting against the illegal and criminal activities of counterfeit and shoddy products. At present, our country is still in the initial stage of market economy development, the market system is not perfect, and the competition mechanism is not perfect. Illegal and criminal acts of counterfeiting and shoddy products not only disrupt the market order and damage the legitimate rights and interests of manufacturers of famous and high-quality products, but more seriously, they directly endanger the health of the general public and the environment. Therefore, crac...
