Embodiment 1

[0028] Make polyvinyl alcohol into a solution of about 35%, and add anti-counterfeiting powder (all particle sizes are less than 3 μm, can directly withstand 365nm ultraviolet light continuous irradiation for 60 hours; can withstand 140°C for 30 minutes) into the solution:

[0029] Temperature-changing powder (produced by Beijing Chenlei Technology Co., Ltd.): reversible discoloration in the temperature range of 50-60 ° C, red at room temperature, red disappears after heating, the amount added is equivalent to about 3% of the polyvinyl alcohol content by weight;

[0030] Phosphor powder (produced by Peking University Deli Technology Co., Ltd.): the amount added is equivalent to about 1% by weight of the polyvinyl alcohol content, and it shows blue fluorescence under ultraviolet light;

[0031] Infrared powder (produced by Peking University Deli Technology Co., Ltd.): the amount added is equivalent to about 1% of the weight of polyvinyl alcohol, and it will show green fluorescen...

Embodiment 2

[0039] Polyvinyl alcohol is prepared into a solution of about 30-40%, and anti-counterfeiting powder is added to the solution (the particle size should be less than 3 μm):

[0040] Temperature-changing powder (produced by Beijing Chenlei Technology Co., Ltd.): reversible discoloration in the temperature range of 50-60°C, blue at room temperature, and disappears after heating. The amount added is equivalent to 3-4% by weight of polyvinyl alcohol content about;

[0041] Phosphor powder (produced by Peking University Deli Technology Co., Ltd.): the amount added is equivalent to about 2% by weight of the polyvinyl alcohol content, and it shows yellow fluorescence under ultraviolet light;

[0042] Infrared powder (produced by Peking University Deli Technology Co., Ltd.): the amount added is equivalent to about 1.5% by weight of the polyvinyl alcohol content, and it will show red fluorescence under infrared irradiation;

[0043] The above-mentioned polyvinyl alcohol solution added ...

Abstract

The invention provides a triple anti-counterfeiting material, its raw material composition includes a carrier and an anti-counterfeiting powder, the carrier is selected from products made of polyvinyl alcohol, polyacryl alcohol, polyamide or viscose fiber, and the anti-counterfeiting powder includes temperature change Materials, fluorescent materials and infrared materials, the content of temperature-changing materials in the anti-counterfeiting material is 1-6% of the weight of the carrier, and the content of fluorescent materials and infrared materials is 0.5-3% of the weight of the carrier respectively; the above-mentioned multifunctional anti-counterfeiting materials not only enhance the The anti-counterfeiting effect of the prior art (to achieve triple anti-counterfeiting), and the firmness of the combination with the paper base is also improved, which solves the problem of poor publicity of the prior art.

Description

technical field [0001] The invention relates to an anti-counterfeiting material, in particular to a multifunctional anti-counterfeiting material applied to paper-based products. The anti-counterfeiting material has triple anti-counterfeiting functions of temperature change, fluorescence and infrared, and can be especially used in the manufacture of anti-counterfeiting paper. Background technique [0002] The anti-counterfeiting methods of paper-based products can be roughly divided into physical and chemical methods in terms of identification principles, such as watermarks in banknotes, anti-counterfeiting threads, anti-counterfeiting fibers that can be seen directly by the naked eye, laser holography of credit cards, invisible barcodes of commodities, etc. It belongs to the physical anti-counterfeiting method, and the chemical anti-counterfeiting method is to reveal the product characteristics by checking the chemical reaction of the anti-counterfeiting components under cert...
