Verification information uncovering anti-counterfeiting card and preparation method thereof

Abstract

The invention belongs to the technical field of anti-counterfeiting marks, and particularly relates to a verification information uncovering anti-counterfeiting card and a preparation method thereof. The card comprises a plastic film layer, a coating, a mould pressing holographic information layer, a transfer coating, a polyamide layer, a first printing layer, a pressure-sensitive adhesive layer, a holographic rainbow transfer layer, a first glue layer and a base material layer which are sequentially arranged from top to bottom; the holographic rainbow transfer layer comprises a laser mould pressing information layer and an aluminum plating layer, and the laser mould pressing information layer is located above the aluminum plating layer; the anti-counterfeiting card can be uncovered and is divided into a stripping part and a bottom reserving part, the stripping part is the part above the transfer coating, and the bottom reserving part is the transfer coating and the part below the transfer coating. After the anti-counterfeiting card is uncovered, the upper face and the lower face of the stripping part both display the hidden laser effect, the copy part displays the rainbow holographic effect and the hidden laser effect, and when a consumer identifies hidden information, judges the authenticity of an identifier and adheres the identifier together, the hidden laser information is still displayed; the preparation method is simple and feasible.

Description

Technical field [0001] The present invention belongs to the technical field of anti-counterfeiting identifiers, and specific relates to an unveiling verification information security card and its preparation method thereof. Background technique [0002] Counterfeit and shoddy goods cause huge hazards and losses to enterprises and consumers, anti-counterfeiting techniques are a means of preventing counterfeiting. Development of anti-counterfeiting technologies can provide difficulty for the purification market, which can quickly identify product authenticity identification and anti-counterfeiting cards, etc., protect the legitimate rights and interests of genuine products and consumers. [0003] Nowadays, the anti-counterfeiting card on the market is relatively single, and the preparation process is relatively simple, easy to be patterned or transferred twice. [0004] CN202601083U Announces a laser-type plastic film anti-counterfeiting identifier, which sequentially includes a do...

Problems solved by technology

[0005] In addition, the anti-counterfeiting information in the logo is relatively single, and the anti-counterfeiting effect is limited

At present, the peel-off anti-counterfeiting cards on the market are easy to be peeled off from the substrate paper layer when peeling off, resulting in disorderly layering of the card, which cannot be destroyed from the transfer layer, resulting in the failure to display the laser information and hidden variable information of the logo.
