Film for anti-counterfeiting alteration and application method thereof

Abstract

The invention relates to an anti-counterfeiting altered film applying combination of a flash layer and a polarizing layer and an application method of the anti-counterfeiting altered film, in particular to an anti-counterfeiting altered film and an application method of the anti-counterfeiting altered film, in which a specific pattern is printed in the flash layer, so that whether a specific image or hue is changed or not can be confirmed by naked eyes. The anti-fake alteration film and the electronic tag comprising the film of the present invention simultaneously comprise a means for confirming whether fake alteration is performed or not by using pictures or images shot by naked eyes or a camera in a smartphone, thereby having the advantage of very difficult fake alteration.

Description

【Technical field】 [0001] The present invention relates to an anti-counterfeit and altered film with a combination of a flash layer and a polarizing layer and an application method thereof, specifically, an anti-counterfeit and altered film with a specific pattern printed in the flash layer so that the naked eye can confirm whether a specific image or hue changes or not and an application method thereof . 【Background technique】 [0002] With the development of industry in the 21st century, information and communication technology has also developed accordingly, and ordinary users' awareness of market products and technologies has continued to increase.

Problems solved by technology

In the past, fine patterns, Braille, holograms, RFID and other technologies were mainly used to prevent counterfeiting and alteration of goods, but the problem with this technology is that it is difficult for ordinary users to identify whether the goods are counterfeit or The means of manufacturing need to invest a lot of cost

[0009] However, the problem with the above-mentioned anti-copy RFID tags is that it can only be judged by the RFID reader whether it is fake or not, and it cannot be confirmed by the naked eye.

In addition, the Covert technology for anti-counterfeiting at home and abroad uses more infrared and ultraviolet luminescent materials, but most of them are only one color after the ink itself is applied. The difficulty of the technology itself is not high, so there is also the risk of counterfeiting.
