Embodiment 1

[0011] Embodiment 1: first get a container and get 8 grams of phenolic resin and 75 grams of alkyd resin, 8 grams of zinc salicylate, 8 grams of bromocresol purple, 1 gram of red dry oil in the container, stir with high-speed mixer for 20 minutes, Then grind the stirred material several times with a three-roller grinder, and test it with a scraper fineness meter. When the fineness is ≤15 μm, the finished ink can be packed into a box.

Embodiment 2

[0012] Embodiment 2: first get a container and get 6 grams of phenolic resin and 75 grams of alkyd resin, 10 grams of zinc salicylate, 8 grams of bromothymol blue, 1 gram of red dry oil in the container, stir with a high-speed mixer for 20 minutes, Then grind the stirred material several times with a three-roller grinder, and test it with a scraper fineness meter. When the fineness is ≤15 μm, the finished ink can be packed into a box.

[0013] The double-color developing ink that makes by the present invention can reach following technical index:

[0014] Color: light yellow

Abstract

The invention discloses a dual-visualization ink and preparing method thereof, which includes 79-83 percent offset resin, 10-8 percent of A visualization reagent, 10-8 percent B visualization reagent and 1 percent of drier. The offset resin is offset phenolic resin and alkyd resin, the A visualization reagent is zinc salicylate and the B visualization reagent is bromocresol purple or bromocresol green, and the driers is red drying oil. The preparing method for the dual-visualization ink includes the following steps: first, accurately weighting, stirring and mixing the offset resin, the A visualization reagent, the B visualization reagent and the drier; second, grinding the mixture by a three-roll mill; third, when grinding fineness is less than or equals to 15mum, obtaining the ink. The invention has the beneficial effects that the antifake effect is enhanced and the visualization effect is stable and reliable due to use of the ink made of two kinds of visualization reagents. The dual-visualization ink is convenient for preparation and is suitable for batch printing.

Description

technical field [0001] The invention relates to an offset printing ink; in particular, to an ink capable of multiple color development and a preparation method thereof. Background technique [0002] In recent years, the phenomenon of counterfeit bill labels has appeared from time to time, disrupting the economic order of the society, and at the same time bringing huge economic damage to the merchants. Therefore, merchants pay more and more attention to the printing of bills and labels. Many anti-counterfeiting technologies have promoted the development of the anti-counterfeiting industry, and various new anti-counterfeiting technologies are in the ascendant. At present, when printing bills and labels in the market, a color-changing ink is often used for anti-counterfeiting to achieve a certain anti-counterfeiting effect, but a single color-changing ink still has the risk of being copied. Contents of the invention [0003] The technical problem to be solved by the present ...
