Embodiment I

[0029] Embodiment 1 is a kind of manufacture method of blue fluorescent nuclear micropore comprehensive anti-counterfeiting mark

[0030] The method for manufacturing the blue fluorescent nuclear micropore comprehensive anti-counterfeiting label of this embodiment can basically be divided into five relatively independent manufacturing steps:

[0031] 1. Irradiation of heavy ions The heavy ions produced by the heavy ion accelerator of Shanshan irradiate the transparent polyethylene terephthalate (PET) film in the irradiation vacuum chamber. The heavy ion irradiation process is a disordered random process, so nuclear latent traces that obey statistical laws are formed in the irradiated PET film:

[0032] 2. Production of laser rainbow embossed holographic image This step is completely independent from the above step 1, which is convenient for control and management. Apply laser rainbow hologram plate-making technology and molded replication technology to make a visible or invis...

Embodiment 2

[0040] Embodiment 2 is a manufacturing method of a purple fluorescent nuclear micropore comprehensive anti-counterfeiting label

[0041] The comprehensive anti-counterfeiting mark of purple fluorescent core micropore is one of the comprehensive anti-counterfeiting marks. The method for manufacturing the comprehensive anti-counterfeiting label of purple fluorescent nuclear micropores in the present invention can basically be divided into 6 relatively independent steps:

[0042] 1, heavy ion irradiation; this step is identical with the step 1 of embodiment 1

[0043] 2. Fabrication of laser rainbow embossed holographic images; this step is the same as step 2 of embodiment 1.

[0044] 3. Add 8% fluorescent substance B into the protective glue, stir to dissolve at 115-120°C and mix well. The molecular formula of fluorescent substance B is:

[0045] 4. Printing anti-counterfeiting marks; this step is the same as step 4 of embodiment 1.

[0046] 5. Chemical etching of nuclear mi...

Embodiment 3

[0048] Embodiment 3 is a manufacturing method of a red fluorescent nuclear micropore comprehensive anti-counterfeiting mark

[0049]The red fluorescent nuclear micropore comprehensive anti-counterfeiting mark is one of the comprehensive anti-counterfeiting marks. The method for manufacturing the red fluorescent nuclear micropore comprehensive anti-counterfeiting label of the present invention can basically be divided into 6 relatively independent steps:

[0050] 1, heavy ion irradiation; this step is identical with the step 1 of embodiment 1

[0051] 2. Fabrication of laser rainbow embossed holographic images; this step is the same as step 2 of embodiment 1.

[0052] 3. Add 4.5% o-phenanthroline trifluoroacetylacetonate europium into the protective gel, stir to dissolve at 65-68°C and mix well.

[0053] 4. Printing anti-counterfeiting marks; this step is the same as step 4 of embodiment 1.

[0054] 5. Chemical etching of nuclear micropores; this step is the same as Step 5 o...

Abstract

The invention includes following steps: transparent high molecular polymer film is irradiated by use of heavy ion with certain energy and mass. Laser rainbow mold pressing image hologram is fabricated on the film irradiated. Mark, pattern and character of nuclear micropore with protection against false are printed on the film irradiated. A layer of fluorescence protecting coat is compounded or coated. The said film is processed by etching to form pore, cleaning, drying procedure with chemical etchant. The invention gathers multi protection against false, aesthetic property and practicability in one product, in order to meet higher and higher demand on the technique of protection against false in merchandise market.

Description

Technical field: [0001] The invention belongs to the field of anti-counterfeiting technology, and relates to a method for manufacturing a nuclear micropore track fluorescent integrated anti-counterfeiting label and its products, especially a comprehensive anti-counterfeiting label based on nuclear micropore anti-counterfeiting technology, supplemented by fluorescence and its spectral analysis and other various anti-counterfeiting technologies. A method of manufacturing anti-counterfeiting marks. Background technique: [0002] Comprehensive anti-counterfeiting is a direction of anti-counterfeiting technology development. Laser anti-counterfeiting marks once played an important role. However, in practical applications, some real signs are not easy to identify, and some simulated signs can be false, which greatly reduces the status of laser holographic anti-counterfeiting signs in people's minds. [0003] The nuclear micropores of the polymer on the membrane are produced by h...
