Embodiment 1

[0041] A kind of UV offset printing black irradiated red ink of this embodiment is prepared from raw materials comprising the following parts by weight:

[0042] 31 parts of 605 epoxy acrylic resin,

[0043] 5215 fatty acid modified acrylic resin 30 parts,

[0044] 184 photosensitizer 2 parts,

[0045] 7 parts of 907 photosensitizer,

[0046] Inhibitor 0.1 part,

[0047] UV fluorescent powder SW1-FPR-2 15 parts,

[0048] C100 carbon black 10 parts,

[0049] HDD1 Viscosity regulator 5 parts.

[0050] Among them, 605 epoxy acrylic resin, 5215 fatty acid modified acrylic resin, UV phosphor SW1-FPR-2, C100 carbon black, HDD1 viscosity modifier were purchased from Shanghai Dinglin Anti-counterfeiting Technology Development Co., Ltd., 184 photosensitizer, 907 photosensitizer , Inhibitor purchased from Germany BASF. The polymerization inhibitor can be selected from commonly used polymerization inhibitors, such as hindered amine compounds.

[0051] In the present embodiment, t...

Embodiment 2

[0059] The difference between this embodiment and Embodiment 1 is that the UV offset black irradiated red ink is prepared from the following raw materials in parts by weight:

[0060] 25 parts of 605 epoxy acrylic resin,

[0061] 5215 fatty acid modified acrylic resin 35 parts,

[0062] 184 photosensitizer 3 parts,

[0063] 6 parts of 907 photosensitizer,

[0064] Inhibitor 0.1 part,

[0065] UV fluorescent powder SW1-FPR-2 15 parts,

[0066]C100 carbon black 12 parts,

[0067] HDD1 Viscosity regulator 8 parts.

[0068] All the other are the same as in Example 1.

[0069] The UV offset printing black irradiated red ink product obtained in this example was printed and tested for anti-counterfeiting. It was found that after the printing was completed, it showed a black effect, and the printed area of ​​the printed product could become bright red after being irradiated by ultraviolet light. After leaving the ultraviolet light source, the color of the printed product area re...

Embodiment 3

[0072] The difference between this embodiment and Embodiment 1 is that the UV offset black irradiated red ink is prepared from the following raw materials in parts by weight:

Abstract

The invention discloses a black offset printing ink capable of generating red fluorescence under the UV irradiation. The ink is prepared from the following raw materials in parts by weight: 25 to 35 parts of 605 epoxy acrylic resin, 25 to 35 parts of 5215 aliphatic acid modified acrylic resin, 1 to 3 parts of 184 photo-sensitizer, 6 to 8 parts of 907 photo-sensitizer, 0.05 to 0.1 part of polymerization inhibitor, 15 to 18 parts of ultraviolet fluorescent powder SW1-FPR-2, 8 to 12 parts of C100 carbon black, and 3 to 8 parts of HDD1 adhesiveness adjusting agent. The invention also discloses a preparation method of the black offset printing ink at the same time. The black offset printing ink is prepared according to the special formula mentioned above, so the ink can generate red fluorescence under ultraviolet excitation.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and in particular relates to a black irradiation red ink for UV offset printing. Background technique [0002] With the rapid development of the packaging and printing industry, the ink industry has grown rapidly accordingly. Among them, UV offset printing inks have incomparable advantages over traditional inks, and have been widely used in cigarette packs, wine packs, cosmetics packs, pharmaceutical packs or Self-adhesive trademarks and other fields. The excellent properties of UV offset printing inks are as follows: [0003] First, it is very suitable for high-speed operation, good printing suitability, fast UV curing speed, and high production efficiency. Generally, it only takes 1 / 10 second to dry completely and fix on the surface of the substrate; [0004] Second, improve the performance of the product, with good water resistance, oil resistance, and anti-fouling properties; ...
