Holographic rainbow laser secret type anti-counterfeiting mark and preparation method thereof

Abstract

The invention belongs to the technical field of anti-counterfeiting marks, and particularly relates to a holographic rainbow laser secret type anti-counterfeiting mark and a preparation method thereof. The mark comprises a plastic film layer, a coating, a mould pressing holographic information layer, a transfer coating, a polyamide layer, a printing layer, a pressure-sensitive adhesive layer, a holographic rainbow transfer layer, a first glue layer, a fragile paper layer and a second glue 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; and the mark can be uncovered and is divided into a stripping part and a copy part, the stripping part is the part above the transfer coating, and the backing part is the transfer coating and the part below the transfer coating. After the mark is uncovered, the upper surface and the lower surface of the stripping part both display a hidden laser effect, the copy part displays the rainbow holographic effect and the hidden laser effect, and when a consumer identifies the hidden information, judges the authenticity of the mark and adheres the mark together, the hidden laser information is still displayed; and the preparation method is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting marks, in particular to a holographic rainbow laser concealed anti-counterfeiting mark and a preparation method thereof. Background technique [0002] Counterfeit and shoddy goods cause huge harm and losses to enterprises and consumers. Anti-counterfeiting technology is a means to prevent counterfeiting. The development of anti-counterfeiting technology can provide the purification market with a mark that is difficult to forge and can quickly identify the authenticity of products, and protect the legitimate rights and interests of genuine product producers and consumers. [0003] Most of the anti-counterfeiting marks on the market are relatively simple in form, and the preparation process is relatively simple, so they are easy to be copied or transferred for secondary use.

AI Technical Summary

Problems solved by technology

[0005] However, the anti-counterfeiting label described in this patent encounters a problem in the actual use process: in a warm and humid environment, when the label is taken and pasted on the object, the label will separate and fall off from the separation layer, and when it falls off, it will Take away part of the digital printing layer information, making the logo unusable and severely restricting its use

In addition, the anti-counterfeiting information in this mark is relatively single, and the anti-counterfeiting effect is limited
