[0002] Holographic anti-counterfeiting refers to an anti-counterfeiting technology completed by using laser color hologram plate-making technology and molded replication technology. At present, holographic anti-counterfeiting films generally use PET film or OPP film as a carrier, and then sequentially coat information with holograms on the carrier. layer and protective layer, but because many certificates are mostly made of PVC, it is difficult for the holographic anti-counterfeiting film with PET film or OPP film as the carrier to be closely attached to the PVC material certificate, which urgently needs to be developed. The current holographic anti-counterfeiting film with PVC film as the carrier mainly has the following defects in the production process of holographic anti-counterfeiting film on the market:
[0003] Because PVC film is not resistant to high temperature, it is easy to deform when it exceeds 80°C, and the molding temperature of holographic anti-counterfeiting film is generally 120°C-200°C, so the holographic anti-counterfeiting film with PVC film as the carrier is not suitable for conventional heating and pressing holographic pressure. The pattern process can only use UV curing method, and UV curing will lose part of the holographic stripes due to liquid coating flow, mold size and other reasons during the production process, which will affect the clarity of the hologram

Abstract

The present invention opens a holographic anti-counterfeiting film production process. It is a laser anti-counterfeiting technology field. It adopts the method of transfer. First, the PET membrane is used as a carrier. At a temperature of 60-80 ° CThe printing of the holographic information is ensured, and then the information layer with a holographic diagram is transferred to the PVC film with a adhesive to solve the traditional PVC holographic anti -counterfeiting membrane.Modern pressure obtains the short -term image shortage of holographic images.
