Problems solved by technology

[0003] At present, the anti-counterfeiting technical means used for documents are mainly reflected in printing and paper, electronic information, and Internet technology. The former is easy to counterfeit and difficult to identify, while the latter requires terminal equipment, which is not suitable for any venue or regional screening, and has certain limitations.

Embodiment 1

[0040] A security anti-counterfeiting film for transfer type documents such as figure 1 As shown, the base layer 1 of 20 μm optical grade PET base film is used, and the separation layer 2 is coated on the surface layer by the same coating machine, and the modified two-component epoxy resin is used as the protective layer 3 coating, and the reaction is cured. Then coat the information layer 4, and use commercial molding equipment to copy the optical structure on the motherboard to the surface of the information layer, and perform corona treatment on the surface of the information layer. Use a continuous vacuum coating machine to perform zinc sulfide electroplating on the molded information layer to embed the dielectric film layer 5, and finally use a coating machine to apply high-temperature hot-melt adhesive to obtain an adhesive layer 6, and carry out the above-mentioned semi-finished coil material suitable for certificate transfer Slitting of equipment specifications and len...

Embodiment 2

[0042] The second transfer-type document security anti-counterfeiting film such as figure 1, using 20μm optical grade PET base film base layer 1, coating the separation layer 2 on the surface layer with a coating machine, using modified two-component epoxy resin as the protective layer 3 coating, and coating after reaction curing UV information layer 4, copying and curing the optical structure on the motherboard on the surface of the UV layer; corona treatment is carried out on the surface of the information layer, and the information image obtained by copying is tracked and positioned with a digital printing machine to print the cursor code, as shown in Figure 4 (a ); Use a continuous vacuum coating machine to carry out zinc sulfide electroplating and landfill on the information layer after molding. figure 1 , and finally use a coating machine for high-temperature hot-melt adhesive coating to obtain a coating see figure 1 , cut the above-mentioned semi-finished coil material...

Embodiment 3

[0044] The third type of security anti-counterfeiting film for transfer documents figure 1 , use 20μm optical grade PET base film base layer 1, and use a coating machine to coat the separation layer 2 on the surface layer; use modified two-component epoxy resin as the protective layer coating 3; after reaction and curing, coat Cloth the information layer 4; adopt commercial positioning molding and printing integrated equipment, first input the film material coated with the information layer into the molding unit, copy the optical structure on the motherboard to the surface of the information layer by hot pressing, and then directly enter the printing unit , register the printed ink tracking line and position the cursor through the molded information, see Figure 4(a); corona treatment is performed on the surface of the information layer; zinc sulfide electroplating is used to bury the molded information layer with a continuous vacuum coating machine, see Figure 4(a). figure 1 ,...

Abstract

The invention relates to the field of public security identification, and mainly relates to a transfer type perspective safe-guarding and anti-counterfeiting film for protecting certificate security. The film consists of at least six layers of different chemical materials, wherein the first layer is a basic layer 1 of which the thickness is 15-25 microns; the second layer is a separation layer 2 of which the thickness is 1-2 microns; the third layer is a protection layer 3 of which the thickness is 2-4 microns; the fourth layer is an information layer 4 of which the thickness is 2-3 microns; the fifth layer is a medium film layer 5 of which the thickness is 0.04-0.1 micron; the sixth layer is a bonding layer 6 of which the thickness is 2-5 microns. The perspective safe-guarding and anti-counterfeiting film is attached to the surface of a certificate to generate a visible diffraction optical anti-counterfeiting image. The transfer type perspective safe-guarding and anti-counterfeiting film has the advantages that a six-layer structure needs to be adopted, and a design layer is added to completely meet the requirement of certificate protection; the film has high resistance to scratching, wiping, sweat stain, oil stain, weak acids and alkalis as well as solvent erosion, has high flexibility in comparison to an ordinary laser holographic film, and contributes to effective prolonging of the service life of the certificate; a high polymer chemical material process is adopted.

Description

[technical field] [0001] The invention relates to the field of public safety identification, mainly used for visual anti-counterfeiting identification of documents such as passports, visas, driver's licenses, vehicle driving licenses, passes, real estate certificates, etc., and is one of the most effective technical measures for preventing counterfeiting and tampering of document texts It has broad application prospects in the field of public security and prevention at home and abroad. [Background technique] [0002] Certificates are used in fields such as identification, important circulation management, qualification certificates, and ownership certificates. The text content contains important legal information of the holder. This content includes the original login information of the issuing agency, and new marking and issuance are also required to be recorded. content. Therefore, the protection of its text information after writing is very important. It is not uncommon ...
