Embodiment 1

[0058] Formulation (weight percent)

[0059]

[0060] Preparation:

[0061] (1) first add the auxiliary agent to 90% of the total reactive diluent weight, then add the magnetic pearlescent pigment, disperse, and obtain solution 1;

[0062] (2) Add the remaining active diluent to the formula amount Among 9033 and CN9178, solution 2 was obtained by dispersing and dissolving uniformly;

[0063] (3) Mix solution 1, solution 2 and the GENOMER 7210 of formula quantity, disperse evenly, obtain the ink composition that does not contain photopolymerization initiator;

[0064] Before the ink is printed, the photopolymerization initiator can be added to the ink composition according to the proportion;

[0065] After printing is completed, it will be tested after 72 hours.

Abstract

The invention discloses a cationic-radical UV (Ultraviolet)-cured pearly-luster silk screen ink and a preparation method thereof. The ink is prepared from the following components in percentage by weight: 20 to 80% of UV-cured resin, 5 to 30% of magnetic pearly-luster pigment, 3 to 20% of active monomer diluents, 4 to 12% of photoplymerization, 0 to 10% of solvent, and 3 to 8% of additive. The cationic-radical UV-cured magnetic pearly-luster silk screen ink has a dynamic optical effect that pear luster changes as the change changes and is easily recognized by the public; in addition, the ink has a post-curing characteristic through which the problem of easy falling and bubbling of the surface of an ink film at the part in which sheet-shaped magnetic pigments are vertically arranged can be solved.

Description

technical field [0001] The invention relates to a magnetic pearl screen ink and a preparation method thereof. Background technique [0002] Ultraviolet (UV) cured magnetic pearlescent screen ink is an ink composition obtained by adding magnetic pearlescent materials to UV cured screen ink. It can be used in high-end anti-counterfeiting fields such as cards and tickets. [0003] Pearlescent ink is a kind of ink for special gloss printing. Pearlescent ink can show pearl or metallic luster on the substrate, making the visual effect of the printed product unique, elegant or luxurious, so it is favored by people. The graphics and texts printed with pearlescent ink can show a unique luster under the light. If it is used in the fields of cards and tickets, it can not only increase its natural beauty, but also facilitate public recognition. At the same time, pearlescent ink can make use of light changes to make Modern scanning, copying and other technologies cannot realize accurate...
