Embodiment 1

[0035] Offset printing ink: (mass percentage)

[0036]

[0037] Weigh the materials in the above proportions into the material barrel, mix them with a mixer for 30 minutes, and grind them on a three-roller mill until the product inspection reaches the technical index of offset printing ink application, then it is X-ray excited luminescent engraving gravure ink.

[0038] figure 1 It is the X-ray absorption imaging image of the ink in the X-ray non-absorbing and absorbing paired ink prints. Among them, (a) is under sunlight, and (b) is under X-ray absorption imaging system.

Embodiment 2

[0040] Engraving gravure printing ink: (mass percentage)

[0041]

[0042]

[0043] Weigh the materials in the above proportions into the material barrel, mix them with a mixer for 30 minutes, and grind them on a three-roller mill until the product inspection reaches the application technical index of engraving gravure printing ink.

Embodiment 3

[0045] UV screen ink preparation:

[0046]

[0047] Weigh the materials in the above ratio into the material bucket, mix them with a mixer for 30 minutes, and filter through a 100-mesh screen. After the product is tested to meet the technical indicators of screen ink application, it will be UV-curable blue X-ray excited luminescent screen ink.

Abstract

The invention discloses an anti-counterfeiting ink composition applicable to judicial expertise. The anti-counterfeiting ink composition is characterized by comprising X-ray absorbing materials. The anti-counterfeiting ink composition is applicable to bank notes, security, bill and goods labels and has the advantages that the anti-counterfeiting printed tickets can be applicable to man-machine quick detection; the anti-counterfeiting features cannot be copied by a scanner or a duplicating machine and can be detected with special instruments; the anti-counterfeiting features are hidden well, and the anti-counterfeiting level is high; the anti-counterfeiting ink composition is high in moisture resistance, heat resistance, acid resistance, alkali resistance, and soap fastness.

Description

technical field [0001] The invention relates to an anti-counterfeiting ink composition. Background technique [0002] At present, near-infrared absorbing anti-counterfeiting ink has been promoted as an anti-counterfeiting means, and has been widely used in the anti-counterfeiting of cards and securities. Chinese patent CN 103242708 A discloses a near-infrared absorbing ink in a wide band of 850-1250nm, which exhibits a good anti-counterfeiting effect. [0003] However, the application of near-infrared absorbing anti-counterfeiting ink has many limitations, such as easy access to materials, simple detection equipment, poor concealment of anti-counterfeiting features, and low anti-counterfeiting level. Contents of the invention [0004] The object of the present invention is to provide an anti-counterfeiting ink composition that can be used for forensic identification, so as to overcome the defects in the prior art. [0005] The anti-counterfeiting ink composition that can...
