Problems solved by technology

As described in the patent application 201110248762X "a kind of UV coating with ice flower effect", the application uses trifunctional polyester acrylate and twelve functional polyurethane acrylate as main raw materials, trimethylol propane triacrylate and Ethyl ester is used as a diluent to prepare UV coatings with ice flower effect, but the above-mentioned ink has the following disadvantages: one is that a volatile solvent is used, which cannot meet the new requirements of environmental protection and energy saving; the other is that the VOC content does not meet the requirements of the environmental protection standards of the tobacco industry ; and more importantly, present tobacco packaging all will have anti-counterfeit function, above-mentioned UV paint does not have anti-counterfeit function, if will increase anti-counterfeit function, then will carry out the printing of anti-counterfeit label etc. in addition, increased the cost of tobacco packaging, also improved reduce the production cost of tobacco packaging

Embodiment 1

[0017] In a stirring open cylinder with a certain volume, according to the weight ratio, mix 5 parts of polyvinyl butyral, 5 parts of polyketone resin, 2 parts of trifunctional polyurethane acrylate resin, 10 parts of acryloyl morpholine (ACMO) and 10 parts Parts of 1,6-hexanediol diacrylate (HDDA) were mixed, and dispersed at a medium speed with a disc stirring blade for 20 minutes to obtain a pre-prepared resin solution; the photoinitiator was mixed with the remaining 37 parts of 1,6-hexanediol diacrylate Acrylate cooking; then add 8 parts of active amine, 0.5 parts of additive BYK-337 and 0.5 parts of BYK-185 and 1,6-hexanediol diacrylate cooking Photoinitiator mixture (including 3 parts of photoinitiator ITX and 3 parts of photoinitiator 379), the rotation speed is gradually increased from low speed to high speed when starting to stir, and then dispersed and stirred at high speed for 10 minutes; finally add 14 parts of red-to-green light-changing powder and 2 parts of inte...

Embodiment 2

[0019] In a stirring open cylinder with a certain volume, according to the weight ratio, mix 3 parts of polyvinyl butyral, 6 parts of polyketone resin, 3 parts of trifunctional polyurethane acrylate resin, 6 parts of acryloyl morpholine (ACMO) and 12 parts Parts of 1,6-hexanediol diacrylate (HDDA), dispersed for 20 minutes at medium speed with a disk-type stirring blade, to obtain a pre-prepared resin solution; use the remaining 29 parts of 1,6-hexanediol diacrylate Ester cooking; then add 8 parts of active amine, 0.5 parts of additive BYK-337 and 0.5 parts of BYK-185 and light that has been cooked with 1,6-hexanediol diacrylate to the pre-prepared resin solution Initiator mixture (including 4 parts of photoinitiator ITX and 2 parts of photoinitiator 379), the rotation speed is gradually increased from low speed to high speed when starting to stir, and then disperse and stir at high speed for 10 minutes; finally add 13.5 parts of red-to-green light-changing powder and 2.5 Part...

Embodiment 3

[0021] In a stirring open cylinder with a certain volume, according to the weight ratio, mix 3 parts of polyvinyl butyral, 4 parts of polyketone resin, 2 parts of trifunctional polyurethane acrylate resin, 12 parts of acryloyl morpholine (ACMO) and 8 parts 1,6-hexanediol diacrylate (HDDA), dispersed for 20 minutes at a medium speed with a disc-type stirring blade, to obtain a pre-prepared resin solution; use the remaining 41 parts of 1,6-hexanediol diacrylate Ester cooking; then add 8 parts of active amine, 1 part of additive BYK-337 and 1 part of BYK-185 and the light that has been cooked with 1,6-hexanediol diacrylate to the pre-prepared resin solution. Initiator mixture (including 3 parts of photoinitiator ITX and 2 parts of photoinitiator 379), the rotation speed is gradually upgraded from low speed to high speed when starting to stir, and then disperse and stir at high speed for 10 minutes; finally add 8 parts of red-to-green light-changing powder and 2 Part of interferen...

Abstract

The invention relates to gravure snowflake ultraviolet (UV) oil ink with an anti-fake function. The UV oil ink is prepared by mixing the following components according to weight ratio: 9-20 parts of macromolecule resin binding material, 10-20 parts of optical variable pigment, 47-61 parts of reactive diluent, 5-8 parts of photoinitiator, 6-8 parts of active amine and 1-10 parts of assistant. By the components, the gravure snowflake UV oil ink, which is energy-saving, environment-friendly and high in printing adaptability and has the special anti-fake function, is provided. The oil ink can be applied to cigarette packaging objects to represent a snowflake-shaped effect, and has light change effect from red to green and a color-changing and anti-fake function.

Description

technical field [0001] The invention relates to an anti-counterfeiting ink, in particular to a UV ink which is printed on tobacco packages and has a special anti-counterfeiting function and a snowflake effect. Background technique [0002] Snowflake ink has the characteristics of saturated ink color, wear resistance, good adhesion, not easy to change color, and delicate hand feeling. It has the advantages of fine pattern, strong three-dimensional effect, luxurious and elegant visually. It is widely used in cigarette packs, wine boxes, gift boxes and other Print for fine drinks. Printing snowflake ink on the printed matter can make the surface present a layer of thin snow or ice brick-like effect, which is commonly known in the industry as "snowflake" (larger pattern, generally larger than 2mm) or "freezing point" (smaller pattern, general pattern less than mm). [0003] To obtain the snowflake-like effect of printed cigarette packs, solvent screen printing snowflake ink, U...
