Problems solved by technology

The disadvantage of fluorescent ink is that this technology only detects whether there is fluorescent material in the ink. This technology is still easy to be imitated, just add fluorescent powder to the ink.

Embodiment 1

[0035] First, the 10nm magnetic memory material r-Fe 2 o 3 Carry out magnetization, and then give the magnetic memory material r-Fe by electromagnetic conversion 2 o 3 Enter the password information to make the r-Fe of each particle 2 o 3 Zhongdu memorizes the password information with the same content (the tone of C key 2 in the vocal range), take 200 copies of ink, r-Fe 2 o 3 33 parts, 36 parts of 30 nanometer infrared phosphor, 35 parts of 50 nanometer ultraviolet long wave phosphor, 28 parts of 50 nanometer ultraviolet short wave phosphor, 18 parts of surfactant oleic acid, NH 3 6.6 parts, miscible, use NaOH or KOH, NH 4 OH to adjust the PH value of the ink to 8, if not, add a small amount of alkaline compound, add kerosene or fluoroether oil to keep the filling amount of magnetic memory material, infrared phosphor, and ultraviolet phosphor at 13-30 %, add 0.5 parts of anhydrous sodium sulfate to adjust the viscosity, add 5 parts of ethylene glycol to lower the soli...

Embodiment 2

[0037] Firstly, the 30nm magnetic memory material CrO 2 Carry out magnetization, and then give the magnetic memory material CrO through electromagnetic conversion 2 Enter the password information to make each particle of CrO 2 Zhongdu memorizes the password information with the same content (the sound of C key 3 in the range), take 200 copies of ink, CrO 2 37 parts, 38 parts of 30 nanometer infrared phosphor, 30 parts of 50 nanometer ultraviolet long wave phosphor, 29 parts of 50 nanometer ultraviolet short wave phosphor, 20 parts of surfactant oleic acid, NH 3 6.6 parts, miscible, use NaOH or KOH, NH 4 OH to adjust the pH value of the ink to 8.5, if not, add a small amount of basic compounds, add kerosene or fluoroether oil, and keep the filling amount of magnetic memory materials, infrared phosphors, and ultraviolet phosphors at 13-30 %, add 0.2 parts of anhydrous sodium sulfate to adjust the viscosity, add 5 parts of ethylene glycol to lower the solidification temperatur...

Embodiment 3

[0039] First, the 30nm magnetic memory material Co-Fe 2 o 3 Carry out magnetization, and then give the magnetic memory material Co-Fe by electromagnetic conversion 2 o 3 Enter the password information to make the Co-Fe of each particle 2 o 3 Zhongdu memorizes the password information with the same content (the sound of C key 4 in the vocal range), take 200 copies of ink, Co-Fe 2 o 3 32 parts, 30 parts of 30 nanometer infrared phosphor, 28 parts of 50 nanometer ultraviolet long-wave phosphor, 26 parts of 50 nanometer ultraviolet short-wave phosphor, 16.6 parts of the mixture of perfluorooctanoic acid and fluorocarbon oil, NH 3 6 parts, miscible, use NaOH or KOH, NH 4 OH to adjust the PH value of the ink to 9, if it cannot be reached, add a small amount of alkaline compound, add kerosene or fluoroether oil, and keep the filling amount of magnetic memory material, infrared phosphor, and ultraviolet phosphor at 13-30 %, add 1 part of anhydrous sodium sulfate to adjust the v...

Abstract

The invention is a multiple anti-falsification ink with a memory code and a method of detecting the ink marks of writing with it, synthesized of general ink, magnetic memory material, infrared fluorescent material and UV fluorescent material, etc. and the detecting method: making magnetic-electric conversion on the code information in the magnetic material in the ink marks and detecting, identifying the code information, and the infrared light generator excites infrared fluorescent information in the ink marks and the UV light of the UV lamp excites long-short wavelength UV fluorescent information in the ink marks. It has good anti-falsification effect, and the handwriting contains an electromagnetic code, infrared fluorescent information and UV fluorescent information, detected by special apparatuses and the code has uniqueness, so that the falsifier is difficult to simulate, thus able to effectively the occurrence of forging signatures, altering, forging written pledges, and other illegal activities. It is applied to important bills of documents and notes, signature, contracts and documents, etc.

Description

technical field [0001] The invention relates to a writing ink, in particular to a multiple anti-counterfeit ink with memory codes, a detector and a method for detecting ink traces written with the ink. Background technique [0002] The anti-counterfeiting technology of existing ink has several forms, one is by mixing luminescent material in the ink, i.e. fluorescent powder, then irradiating the ink with a purple light lamp, and using the fluorescent reverse signal to judge and identify its authenticity, as in the Chinese patent ( Application number) 96200746 Combination writing highlighter for anti-counterfeiting and anti-theft, which is composed of a fluorescent writing pen with colorless writing ink containing organic ultraviolet fluorescent complexes and an ultraviolet counterfeit detector. Use it to write invisible signatures or passwords on documents and valuables, which can effectively prevent counterfeiting and anti-theft. Immediately after writing, use the ultraviole...
