[0046]

[0047] The X-ray excited luminescent powder is Eu:Lu 2 SiO 5

[0048] The components of the weight percentage of the binder:

[0049] (a) Resin 70%

[0050] (b) Solvent 10%

[0051] (c) Vegetable oil 20%

[0052] Resin is rosin modified phenolic resin

[0053] The solvent is 210# mineral oil;

[0054] The vegetable oil is linseed oil;

[0055] The pigment is FBB permanent red;

[0056] The UV-screening agent is phenyl o-hydroxybenzoate;

[0057] The auxiliary agent is polydimethylsiloxane;

[0058] 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.

Abstract

The invention discloses an anti-forgery ink composition through X-ray excited luminescence. The composition is characterized by comprising an X-ray excited luminescence material. The anti-forgery ink composition can be an offset printing ink, a relief printing ink, a plate engraving ink or a silk screen printing ink and the like. A pattern printed by the anti-forgery ink composition does not give out light or give out weaker light under a UV lamp (Ultraviolet Lamp), but give out UV or visible light under the X-ray excitation, therefore the false of the ink composition can be discerned from the genuine; furthermore, the ink composition can be applied to bank notes, securities, bills and commodity labels. Because the ink composition provided by the invention does not give out light under the UV but give out light under the X-day, the anti-forgery effect is good and the anti-forgery difficulty is high; meanwhile, anti-forgery features need to be detected by virtue of special instruments and equipments, therefore the ink composition can be applied to judicial expertise; in addition, the anti-forgery ink is good in moisture resistance, thermal resistance, acid resistance, alkaline resistance and soap fastness.

Description

technical field [0001] The invention relates to an anti-counterfeiting ink composition which can be used for forensic identification, and more specifically, the invention relates to an anti-counterfeiting ink composition containing materials with X-ray excitation and luminescent properties. Background technique [0002] At present, fluorescent anti-counterfeiting inks such as ultraviolet fluorescent inks and infrared excited fluorescent inks have been widely used in securities. For example, Chinese patent CN104386 discloses a kind of ultraviolet fluorescent anti-counterfeiting ink, which is used for anti-counterfeiting printing of train tickets and ships, but the ultraviolet fluorescent materials used in it are relatively easy to obtain in the market, and it is difficult for high-end anti-counterfeiting. Contents of the invention [0003] The object of the present invention is to provide an X-ray excited luminescent anti-counterfeiting ink composition to overcome the defec...
