Anti-counterfeiting ink composition and method of use thereof

Abstract

The present invention relates to the field of anti-counterfeiting technology, specifically a kind of anti-counterfeiting ink composition with moderate viscosity, which can meet the requirements of reliable preservation of anti-counterfeiting patterns in the identification period and timely elimination of anti-counterfeiting patterns after the identification period, and its use method, which is characterized in that it comprises the following: Components: water, thymolphthalein or phenolphthalein, glycerin, alcohol, sodium stearate or sodium polyacrylate, sodium hydroxide, when the cover plate of the anti-counterfeiting label is destroyed during use, part or all of the information on the label will be displayed on the Disappear within a period of time, this method can solve the disadvantages of high anti-counterfeiting costs and cumbersome search methods, and at the same time effectively prevent counterfeiters from using the old packaging of the product to fake in batches.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to an anti-counterfeiting ink composition with moderate viscosity, which can meet the requirements of reliable preservation of anti-counterfeiting patterns during the identification period and timely elimination of anti-counterfeiting patterns after the identification period and its use method. Background technique [0002] The existing anti-counterfeiting means mainly include: chemical ink anti-counterfeiting, digital anti-counterfeiting (SMS anti-counterfeiting, telephone anti-counterfeiting), optical anti-counterfeiting, barcode anti-counterfeiting, two-dimensional code anti-counterfeiting, radio frequency anti-counterfeiting, etc. Among them, the chemical ink is anti-counterfeiting, and the anti-counterfeiting method is visual observation, which has great limitations. The imitators will directly obtain forged information according to the intuitive color of the ink fo...

Problems solved by technology

Consumers can obtain the authenticity of the product by checking several sets of numbers on the label or packaging, and by sending text messages or calling the merchant's inquiry platform to inquire about the authenticity of the product. However, this method is cumbersome to use, especially when consumers enter information on the keyboard. It is easy to enter wrongly or the input speed is slow, which is not conducive to convenient and fast query

Two-dimensional code anti-counterfeiting is an emerging orientation or information query technology in recent years. It mainly uses the two-dimensional code pattern to use the PC terminal, that is, the mobile phone, to use the mobile phone scanning software to identify the two-dimensional code information, and upload it to the merchant website to query and get the reply product. However, in this method, the QR code pattern of a category of products is fixed, and it is easy for counterfeiters to copy the pattern printing, because the information in the batch of products is fixed, so it is easy for counterfeiters to fake in batches , and this method requires multiple authentications, and it cannot guarantee that the buyer is the first authenticator, and at the same time reduces the query rate

Barcode anti-counterfeiting, the principle and mechanism are almost the same as QR code search, which cannot prevent counterfeiters from making large-scale counterfeiting

[0003] In order to solve the above problems, the researchers proposed a disappearable anti-counterfeiting pattern, so that the anti-counterfeiting pattern can be eliminated after the identification period, effectively preventing the anti-counterfeiting pattern from being copied and imitated. This kind of technology requires ensuring the stability of the anti-counterfeiting pattern during the identification period. The anti-counterfeiting ink is a water-based substance. When it is applied to the anti-counterfeiting label, it is easy to overflow from the ink bag structure in the case of violent collision, damage the dot matrix numbers, cause the anti-counterfeiting information to be lost and incomplete, and have poor stability.
