Problems solved by technology

Most customers "turn a blind eye", coupled with insufficient publicity, most customers do not know whether the Zhonghua cigarettes they smoke are genuine or not
Therefore, the anti-counterfeiting function of the existing anti-counterfeiting inkjet ink is poor

Embodiment 1

[0031] Combine 5 parts of nitrocellulose, 10 parts of epoxy resin, 7 parts of fluorescent orange red, 1 part of phosphor, 70 parts of methyl ethyl ketone, 0.4 parts of polyoxyethylene octyl phenol ether-10 and 0.1 part of N-methylpyrrolidone at 30°C Mix for 20 minutes, and grind at 45°C to obtain fluorescent anti-counterfeiting inkjet ink.

[0032] The fluorescent anti-counterfeiting inkjet ink prepared in Example 1 of the present invention is orange-red in appearance, and orange-red fluorescence under ultraviolet light irradiation, which realizes the organic combination of invisible fluorescence and apparent appearance, and has a high anti-counterfeiting function.

Embodiment 2

[0034] Combine 8 parts of nitrocellulose, 5 parts of epoxy resin, 10 parts of fluorescent red, 2 parts of phosphor, 75 parts of methyl ethyl ketone, 0.5 parts of polyoxyethylene octyl phenol ether-10 and 0.7 parts of N-methylpyrrolidone at 35°C Mix for 30 minutes, roll and grind at 40°C to obtain fluorescent anti-counterfeiting inkjet ink.

[0035] The fluorescent anti-counterfeiting inkjet ink prepared in Example 2 of the present invention is orange-yellow in appearance and orange-yellow fluorescence under ultraviolet light irradiation, which realizes the organic combination of invisible fluorescence and apparent appearance, and has a high anti-counterfeiting function.

Embodiment 3

[0037] Combine 10 parts of nitrocellulose, 7 parts of epoxy resin, 5 parts of fluorescent pink, 1.5 parts of phosphor powder, 80 parts of methyl ethyl ketone, 0.15 parts of polyoxyethylene octyl phenol ether-10 and 0.4 parts of N-methylpyrrolidone at 40°C Mix for 10 minutes and grind at 30°C to obtain fluorescent anti-counterfeiting inkjet ink.

[0038] The fluorescent anti-counterfeiting inkjet ink prepared in Example 3 of the present invention is orange-red in appearance, and orange-red fluorescence under ultraviolet light irradiation, realizing the organic combination of invisible fluorescence and apparent appearance, and having a high anti-counterfeiting function.

[0039] It can be seen from the above embodiments that the fluorescent anti-counterfeiting inkjet ink provided by the present invention, in parts by weight, includes the following components: 5-10 parts of nitrocellulose, 5-10 parts of epoxy resin, and 5-10 parts of solvent-based fluorescent dyes. , 1-2 parts of fluo...

Abstract

The invention provides fluorescent anti-counterfeiting printing ink. The fluorescent anti-counterfeiting printing ink comprises the following components: 5-10 parts of nitro-cotton, 5-10 parts of epoxy resin, 5-10 parts of a solvent type fluorescent dye, 1-2 parts of fluorescent powder, 70-80 parts of an organic solvent, 0.1-0.5 part of polyoxyethylene octyl phenol ether-10, and 0.1-0.7 part of N-methyl pyrrolidone; and the solvent type fluorescent dye is chosen from one or more of fluorescent orange red, fluorescent red and fluorescent peach. The provided fluorescent anti-counterfeiting printing ink is orange-yellow under the synergic action of the components at the specific contents, and shows orange-yellow fluorescence under the irradiation of an ultraviolet lamp; the ink is orange redand shows orange red fluorescence under the irradiation of the ultraviolet lamp; and the invisible fluorescent ink and the apparent style ink are organically combined, and therefore, the anti-counterfeiting function of the fluorescent anti-counterfeiting printing ink is better.

Description

Technical field [0001] The invention relates to the technical field of coding inks, in particular to a fluorescent anti-counterfeiting coding ink. Background technique [0002] Inkjet printer ink is a kind of liquid ink that can be ejected from the nozzle of an inkjet printer and sprayed on the surface of the substrate as required by the force of an electric field to produce image characters. It is a very demanding special ink. It must be stable, non-toxic, non-clogging nozzles, good moisture retention and sprayability, no corrosion to metal objects such as nozzles, and not easy to burn and fade. There are many types of inks for inkjet printers, and each ink has different uses. For example, high-adhesion inks, mostly black and blue, are used for plastic, metal, and food plastic outer packaging; gasoline-resistant inks, black inks, and inks that keep good adhesion after contact with gasoline or alcohol. For auto parts coding; anti-counterfeiting invisible ink, invisible ink that...
