Purple-port pearlescent light variation false proof printing ink

Abstract

A magnetic purple pearlescent light-variation anti-fake ink comprises an anti-fake pigment, a bonder, filler, a flatting agent, a wetting agent, an antifoam agent and a solvent. The anti-fake ink is characterized in that the compositions in weight proportion of the ink are: 5 to 30g of green-to-purple magnetic anti-fake pigment (the pigment), 20 to 40g of macromolecular polymerization resin (the bonder), 5 to 20g of pearl essence (the filler), 0.3 to 3g of flatting agent, 0.3 to 3g of wetting agent, 0.5 to 3g of antifoam agent and 40 to 60g of n-propyl ester (the solvent). The magnetic purple pearlescent light-variation anti-fake ink has the following characteristics that: (1) the anti-fake ink has a professional anti-fake technology; (2) the light-variation effects of the prior light-variation ink is changed, and a process anti-fake function of a light-variation ink is increased; (3) the anti-fake ink adds a 'blue-to-purple' color-changing color system which can not be realized by the prior color-changing ink; and (4), through adding purple pearl essence, the particle of a color-changing ink becomes larger, and solid content in the ink is increased, thereby obtaining more printed work, increasing output capacity and improving printing texture on the basis of identical ink consumption.

Description

technical field [0001] The invention relates to a printing ink, which is a kind of magnetic 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. However, as a first-line anti-counterfeiting ink, optically variable ink mainly makes the pattern or text area printed by the ink change in color with different viewing angles. The anti-counterfeiting function it can provide is relatively simple and is easy to be imitated. [0004] Moreover, due ...

Problems solved by technology

[0006] In order to overcome the disadvantages of single anti-counterfeit function, low color and high material consumption of current optical variable ink, the present invention is based on magnetic optical variable ink and implements process anti-counterfeit by adding special filler purple pearl powder, thereby providing a new high-performance Magnetic purple pearlescent photochromic anti-counterfeiting ink makes it more complex, vivid and unique anti-counterfeiting performance, increases the multiple anti-counterfeiting effects of magnetic zero and photochromic, complements the "blue to purple" photochromic ink color change color system, and improves Improve the multi-color decoration effect of optical variable ink. At the same time, by enhancing the three-dimensional texture of ink printing, improving the printing process and reducing the amount of ink used, the purpose of saving raw materials and improving efficiency is achieved.
