Embodiment 1

[0035] Add 0.5 parts of UV-excited green to 13.5 parts of dimethyl sulfoxide (analytical pure), 31.5 parts of methyl acetate (analytical pure): butyl ester (analytical pure) in a mixed ester solvent of 1:4 (weight ratio) Fluorescent anti-counterfeiting material (hereinafter referred to as green fluorescent material), heated magnetically and stirred evenly at 30°C, stirred for 45 minutes to form component A; added 11 parts of N,N-methyl formazan to 15.5 parts of epoxy resin (commercially available) Amide (analytical pure), 26.5 parts of propylene glycol methyl ether (analytical pure) ether solvent, in which synthetic resin is, after magnetic stirring evenly, component B is formed, components A and B are mixed and stirred for 30 minutes until the solution is completely transparent, add 1 part Organic fluorine surfactant (TEGO), 0.5 parts of pH regulator triethanolamine (analytical pure). Mix and stir for 20 minutes to obtain the ink, which can be spray-painted on the substrate. ...

Embodiment 2

[0040] Add 3.5 parts of green fluorescent material to 17.5 parts of sulfolane (analytical pure) and 34.5 parts of propylene glycol methyl ether acetate (analytical pure), heat and magnetically stir evenly at a temperature of 55 ° C, and stir for 50 minutes to form A component; add 15.5 parts Add 13.5 parts of N,N-methylacetamide (analytical pure) and 17 parts of ethylene glycol ethyl ether (analytical pure) to polyurethane resin (commercially available), and stir magnetically for 30 minutes to form component B, components A and B Mix and stir for 40 minutes until the solution is completely transparent, add 1 part of silicone surfactant (TEGO) and 1 part of pH regulator triethylamine (analytical pure). Mix and stir for 25 minutes to obtain the ink, which can be spray-painted on the substrate.

Embodiment 3

[0042] Add 5 parts of green fluorescent material to 20 parts of sulfolane (analytically pure) and 15 parts of propylene glycol methyl ether acetate (analytical pure), heat and magnetically stir evenly at a temperature of 45°C, and stir for 60 minutes to form A component; add 19.5 parts Add 21.5 parts of ethylene glycol ether (analytical grade) and 19 parts of diethylene glycol butyl ether: 1,4-dioxane in a mixed ether solvent of 3:2 (weight ratio) to polyurethane resin (commercially available). After magnetically stirring for 30 minutes to form component B, mix and stir components A and B for 60 minutes until the solution is completely transparent, then add 2 parts of organic fluorine surfactant (TEGO) and 1 part of pH regulator N,N-dimethylformamide (analytical pure). Mix and stir for 10 minutes to obtain the ink, which can be spray-painted on the substrate.

Abstract

The invention relates to ultraviolet excited green fluorescent inkjet ink for printing and imaging by an additive method and a preparation method, belonging to the technical field of anti-counterfeit printing. The ink comprises the following components in parts by weight: 0.1-10 parts of ultraviolet excited green fluorescent anti-counterfeit material, 15-50 parts of esters solvents, 15-30 parts of sulfur-containing solvents, 5-30 parts of synthetic resins, 15-40 parts of ethers solvents, 10-30 parts of nitrogen-containing solvents, 0.5-3 parts of surfactants and 0.5-3 parts of pH regulators. The preparation process of the ink is simple and the components can be completely dissolved and uniformly mixed only through magnetic stirring and heating treatment. The green fluorescent anti-counterfeit inkjet ink is suitable for printing hidden one-dimensional and two-dimensional bar codes on various securities, bills, trademarks and the like, is simple in process preparation, has strong hidden property and can effectively prevent duplicating and counterfeiting.

Description

technical field [0001] The invention relates to an ultraviolet-excited green fluorescent ink-jet ink for color-additive printing and imaging and a preparation method. The ink is a printing ink-jet ink and belongs to the technical field of anti-counterfeiting printing. Background technique [0002] With the improvement of living standards and environmental protection awareness, people have put forward higher requirements for anti-counterfeiting of packaging and printing products. At present, there are a variety of counterfeit products in the market, flooding every corner of the market, which has seriously harmed the interests of producers and consumers. People began to pay more attention to the application of anti-counterfeiting technology in printed matter, not only expecting it to achieve the expected anti-counterfeiting effect, but also to meet high-quality printing performance, simple operation, and high anti-counterfeiting performance. This is a topic that many manufactur...
