Problems solved by technology

[0006] In order to overcome the shortcomings of the current optical variable inks that are not rich in color and consume a lot of materials, the present invention is based on optical variable inks and provides a new high-performance purple pearlescent optical variable anti-counterfeiting ink by adding special fillers such as purple pearlescent powder. It has a more vivid and unique anti-counterfeiting performance, complements the color-changing color system of "blue-to-purple" optical variable ink, improves the multi-color decoration effect of optical variable ink, and at the same time, improves the printing process by enhancing the three-dimensional texture of ink printing , reduce ink consumption, achieve the purpose of saving raw materials and improving efficiency

Embodiment 1

[0023] Prepare materials according to the following weight ratios: 17g of green-to-purple anti-counterfeiting pigment, 30g of acrylic resin, 12g of pearlescent powder, 1.5g of leveling agent, 1.4g of wetting agent, 1.3g of defoamer, and 50g of n-propyl ester.

[0024] The production process is as follows: in a light-shielding and dust-free workshop, the temperature is 24°C, and the humidity is 68%. In the reaction kettle, first put the solvent n-propyl ester, then put in the acrylic resin, stir, add the anti-counterfeiting pigment after it is completely dissolved, and wait for the pigment to disperse evenly Then add purple pearl powder for stirring, and then add leveling agent, wetting agent and defoamer in sequence. After the ink is ready, check the hue and control the viscosity at 60-70S. Use No. 3 Zahn cup to test, the solid content It is 45%. After passing the test, it is filtered with a 200-mesh filter cloth, and packed in an iron drum for storage.

Embodiment 2

[0026] Prepare materials according to the following materials, chameleon brand green-to-purple anti-counterfeiting pigment produced by Huizhou Huayang Optical Technology Co., Ltd., Guangdong Province, GIB65; linking material is produced by Hunan Jinguli Ink and Coating Co., Ltd., which can withstand high temperature of 150 ℃, adhesion Strong and friction-resistant acrylic resin; the filler is Merck brand purple pearl powder produced by Germany Merck Group, with a particle size of 5-10 μm; the leveling agent is Digao 410 produced by Shenzhen Digao Chemical Co., Ltd. The foaming agent is Digo 850 produced by Shenzhen Digo Chemical Co., Ltd., the wetting agent is Liangu 140E produced by Guangzhou Liangu Fine Chemical Co., Ltd., and the concentration of the solvent n-propyl ester is 99%.

[0027] The weight ratios of various components are the same as in Example 1.

[0028] Production technology is identical with embodiment one.

Abstract

Disclosed is violet pearlescent anti-forgery phototropic printing ink, containing anti-forgery dye violet pearl luster, printing ink vehicle, filler, flatting agent, wetting agent, foam killer and solvent. The violet pearlescent anti-forgery ink is characterized in that the weight percentages of the ingredients are as follow: 5-30g green-turn-violet anti-forgery printing ink, 20-40g printing ink vehicle acrylics, 5-20g filler lead carbonate, 0.3-3g flatting agent, 0.3-3g wetting agent, 0.5-3g foam killer, and 40-60g solvent n-propyl. The invention is characterized in that: 1, the phototropic printing ink is hard to forge and is high in fidelity, thus improving actual anti-forgery value; 2,the violet pearlescent phototropic oil, added with violet lead carbonate, supplements the color system of changing from blue to violet, which conventional printing ink fails to realize; 3, the violet pearlescent phototropic oil, added with violet lead carbonate, is enlarged in granule and increased in solid content; on the basis of the same consumption, more printings can be produced, thus improving output and improving the texture of the printings.

Description

technical field [0001] The invention relates to a printing ink, which is a kind of purple pearlescent light-changing anti-counterfeiting ink. Background technique [0002] The so-called anti-counterfeiting ink is a special printing ink made by adding anti-counterfeiting materials with special properties into the ink raw materials and processed by a special process. The specific implementation is mainly printed on tickets, product trademarks and packaging with ink printing. [0003] Most of the anti-counterfeiting features of anti-counterfeiting inks are to allow the public to distinguish between true and false under the conditions of the first time and the first occasion. [0004] Due to the limitations of traditional crafts and materials, the currently widely used optically variable inks only have the following color changes: yellow-green to blue, green to purple, magenta to yellow-green, and purple to deep red. The light-changing color system is relatively fixed and sing...
