preparation example Construction

[0054] Such as figure 1 Shown, a kind of preparation method of the anti-counterfeiting ink with specific spectral line feature, comprises:

[0055] Step S10: First, mix the multi-spectrum organic rare earth complex luminescent pigment, pigment, binder, diluent, filler, and auxiliary agent according to the weight ratio of each component, and stir in the mixing tank for 30 minutes;

[0056] Step S11: Grinding on a grinder until the particle size is not greater than 25 μm, an anti-counterfeit ink with specific spectral line characteristics can be prepared; wherein, the weight ratio of each component refers to:

[0057]

Embodiment 1

[0059] A kind of anti-counterfeiting ink (offset printing colorless) with specific spectral line characteristics has the following components and component ratios:

[0060]

[0061]

[0062] The preparation method is as follows:

[0063] First, mix the multi-spectrum organic rare earth complex luminescent pigments, pigments, binders, diluents, fillers, and additives according to the weight ratio of the above-mentioned components, and stir in the mixing tank for 30 minutes; Grinding on a grinding machine (grinding time greater than 24 hours) until the particle size is not greater than 25 μm, the anti-counterfeiting ink with specific spectral line characteristics can be prepared.

Embodiment 2

[0065] A kind of anti-counterfeiting ink (water-based gravure golden light red) with specific spectral line features has the following components and component ratios:

[0066]

[0067] The preparation method is as follows:

Abstract

The present application provides anti-counterfeiting ink having specific spectral line features and a preparation method of the ink. The ink comprises the following components, in parts by weight: 20-30 parts of a multi-frequency spectrum organic rare earth complex luminescent pigment, 10-15 parts of a pigment, 20-60 parts of a connecting material, 3-5 parts of a diluent, 5-25 parts of a filler and 3-5 parts of an auxiliary agent. The anti-counterfeiting ink with specific spectral line features provided by the invention is nearly colorless, can be used to print various invisible barcodes and figures invisible to naked eyes on various invoices, Hong Kong and Macao passes, passports, banknotes, ID cards, credit cards, lottery tickets and the like, has strong concealment, strong confidentiality and high anti-counterfeiting strength, can effectively prevent copying and counterfeiting, has simple identification operation, quick identification and strong aging resistance, and is convenient for promotion.

Description

technical field [0001] The present application relates to the technical field of inks, in particular to an anti-counterfeiting ink with specific spectral line characteristics and a preparation method thereof. Background technique [0002] Today's social economy is highly developed, economic activities are becoming more and more frequent, and people's pursuit of material is also increasing, and the "counterfeiting industry" is also developing very rapidly. The prevalence of counterfeit and shoddy products has caused huge losses to the country and seriously damaged the interests of the people. [0003] The "counterfeiting industry" is becoming more and more rampant, and the means of counterfeiting are becoming more and more advanced. Conventional primary and secondary anti-counterfeiting technologies are easily forged. For example, the existing anti-counterfeiting ink is to add some specific substances to the ink to make fluorescent ink, photochromic ink, temperature-changing...
