Problems solved by technology

[0003] At present, the fluorescent anti-counterfeiting inks used in the market are of various qualities and different manufacturers. It is difficult for users to identify good and bad. When encountering counterfeiting by their peers, the manufacturer cannot provide reasonable evidence in favor of itself, and cannot explain whether the printed product is the manufacturer’s own product or not. Self-produced products, therefore, the existing fluorescent anti-counterfeiting inks have poor anti-counterfeiting effects

Embodiment 1

[0036] Mix 10 parts of infrared fluorescent powder, 25 parts of zirconia, 70 parts of offset printing ink and 3 parts of low-aromatic mineral oil at 25°C for 30 minutes, and grind at a temperature lower than 65°C to obtain fluorescent encryption anti-counterfeiting ink.

[0037] The fluorescent encrypted anti-counterfeiting ink prepared in Example 1 exhibits fluorescent effects under ultraviolet or infrared fluorescent lamps, and specific data are detected under special instruments.

[0038] The fluorescent encrypted anti-counterfeit ink prepared in Example 1 is printed as an anti-counterfeit area of ​​2mm × 3mm, and it is observed to emit green fluorescence under the irradiation of an infrared lamp; it is detected under a special instrument, and there is corresponding detection data. According to the data, it can be Judging the fidelity of the anti-counterfeiting ink, it has a double anti-counterfeiting effect, that is, it has a good anti-counterfeiting effect.

Embodiment 2

[0040] Mix 25 parts of ultraviolet fluorescent powder, 15 parts of strontium oxide, 60 parts of gravure printing ink and 10 parts of additives at 25°C for 30 minutes, and grind at a temperature lower than 65°C to obtain fluorescent encryption anti-counterfeiting ink.

[0041] The fluorescent encrypted anti-counterfeiting ink prepared in Example 2 exhibits a fluorescent effect under ultraviolet or infrared fluorescent lamps, and the viscosity is 30s / 25°C, and the specific data is detected under a special instrument.

[0042]The fluorescent encryption anti-counterfeiting ink prepared in Example 2 is printed as an anti-counterfeiting area of ​​3 mm × 3 mm, and it is observed to emit yellow fluorescence under ultraviolet light; it is detected under a special instrument, and there are corresponding detection data, according to the data. Judging the fidelity of the anti-counterfeiting ink, it has a double anti-counterfeiting effect, that is, it has a good anti-counterfeiting effect. ...

Embodiment 3

[0044] Mix 25 parts of infrared fluorescent powder, 15 parts of yttrium oxide, 60 parts of gravure printing ink and 10 parts of additives at 25°C for 30 minutes, and grind at a temperature lower than 65°C to obtain fluorescent encryption anti-counterfeiting ink.

[0045] The fluorescent encrypted anti-counterfeiting ink prepared in Example 3 exhibits fluorescent effects under ultraviolet or infrared fluorescent lamps, and specific data are detected under special instruments.

[0046] The fluorescent encrypted anti-counterfeit ink prepared in Example 3 is printed as an anti-counterfeit area of ​​2mm × 2mm, and it is observed to emit green fluorescence under the irradiation of an infrared lamp; it is detected under a special instrument, and there is corresponding detection data, according to the data. Judging the fidelity of the anti-counterfeiting ink, it has a double anti-counterfeiting effect, that is, it has a good anti-counterfeiting effect.

Abstract

The invention provides fluorescent encryption anti-counterfeiting ink and application of the fluorescent encryption anti-counterfeiting ink. The ink comprises the following components by weight: 7-25parts of fluorescent powder, 7-25 parts of encryption powder, 60-80 parts of printing ink, and 1-10 parts of an auxiliary; and the encryption powder is chosen from metallic oxide. The provided fluorescent encryption anti-counterfeiting ink has double anti-counterfeiting effects under the synergetic effects of the components at the specific contents, and the anti-counterfeiting effect is good. Theexperiment result shows that the ink shows corresponding fluorescence under the irradiation of the infrared ray or an ultraviolet lamp; and the printing ink is detected by a special instrument on an anti-counterfeiting area with the printing area not less than 2mm*2 mm, and has corresponding detection data, the fidelity of the anti-counterfeiting ink is judged according to the data, and the ink has the double anti-counterfeiting effect.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a fluorescent encryption anti-counterfeiting ink and an application thereof. Background technique [0002] With the rapid development of the social economy and the rapid development of science and technology, while the commodity economy is booming, the phenomenon of counterfeiting in the society emerges in an endless stream. In order to prevent the further spread of counterfeiting, anti-counterfeiting technology has emerged, and fluorescent anti-counterfeiting ink is one of them. Fluorescent anti-counterfeiting ink is a kind of ink that can emit fluorescence after being irradiated by visible light or ultraviolet light. Fluorescent encryption anti-counterfeiting ink is different from ordinary fluorescent inks because the encryption components in the ink are unique and have double anti-counterfeiting properties. Therefore, when identifying its authenticity, as long as a special inst...
