Problems solved by technology

[0002] The anti-counterfeiting of fluorescent inks has been used for hundreds of years, especially infrared excitation inks and ultraviolet excitation inks have also been widely used in the anti-counterfeiting industry. The technology of sensory identification of authenticity seems simple and easy, but it is actually unreliable, because the human eye's color discrimination is actually very vague, and criminals can easily create imitations with similar colors that cannot be discerned by the human eye. pin to

Embodiment 1

[0040] Customer order 500,000 pieces

[0041] (1) Coating: Coating the prepared coating solution on PET with a thickness of 16 μm, using a 110-mesh metal plate roller, setting the oven temperature to 75° C., and the speed to 60 m / min. The coating solution is made of the following raw materials in weight percentage:

[0042] Organic photoluminescent material: CD-238: 0.7%; CD-152: 0.1%

[0043] Rosin: 16%

[0044] Isopropanol: 83.2%

[0045] CD-238 and CD-152 are produced by INKSURE Technologies.

[0046] (2) Molding: On the transparent disposable anti-counterfeiting material, use a molding machine to copy the holographic information onto the release layer. The transparent disposable anti-counterfeiting material is composed of PET and the release layer.

[0047] (3) Aluminizing: The disposable anti-counterfeiting material is aluminized by vacuum aluminizing method. The square resistance of the aluminum plating layer is 0.8.

[0048] (4) Compounding: Use a compounding mach...

Embodiment 2

[0053] 1 million customer orders

[0054] (1) Coating: use a 130-mesh metal plate roller to coat the prepared coating solution on the PET with a thickness of 20 μm, set the oven temperature to 85° C., and the speed to 70 m / min. The coating solution is made of the following raw materials in weight percentage:

[0055] Organic photoluminescent material: CD-238: 1%

[0056] C9 petroleum resin: 20%

[0057] Absolute ethanol: 79%.

[0058] (2) Molding: On the aluminum-plated disposable anti-counterfeiting material, use a molding machine to copy the holographic information to the release layer. The aluminum-plated disposable anti-counterfeiting material is composed of PET, release layer and aluminum-coated layer.

[0059] (3) Aluminum washing: Use an aluminum washing machine to wash off the aluminum in the digital area and printing area.

[0060] (4) Overprinting: Use the method of secondary printing to print digital and graphic texts to the specified positions.

[0061] (5) Co...

Embodiment 3

[0066] 2 million customer orders

[0067] (1) Coating: Coat the prepared coating solution on PET with a thickness of 50 μm, use a 150-mesh metal plate roller during coating, set the oven temperature to 95° C., and the speed to 80 m / min. The coating solution is made of the following raw materials in weight percentage:

[0068] Organic photoluminescent material: CD-152: 1.2%

[0069] C5 petroleum resin: 18%

[0070] Isopropanol: 80.8%.

[0071] (2) Molding: On the transparent disposable anti-counterfeiting material, use a molding machine to copy the holographic information onto the release layer. The transparent disposable anti-counterfeiting material is composed of PET and the release layer.

[0072] (3) Aluminizing: The disposable anti-counterfeiting material is aluminized by vacuum aluminizing method. The square resistance of the aluminum plating layer is 1.2.

[0073] (4) Aluminum washing: Use an aluminum washing machine to wash off the aluminum in the digital area.

Abstract

The invention belongs to the technical field of anti-counterfeiting labels, and in particular relates to an organic photoluminescent material information anti-counterfeiting label and a preparation method thereof. The organic photoluminescent material information anti-counterfeiting label is formed by a PET layer, an organic photoluminescent material layer, an information layer, an aluminum plating layer, a release layer, an adhesive layer and a silicon oil paper layer sequentially connected from top to bottom. The organic photoluminescent material information anti-counterfeiting label and the preparation method thereof have the advantages that the problem how to select the proportions of the organic photoluminescent material is solved, the problem how to enable optical recognition and reading systems to correspond to spectrums of light emitted by the organic photoluminescent materials one to one is solved, the problem how to prevent the organic photoluminescent materials from being lost during production is solved, and the anti-counterfeiting strength of the anti-counterfeiting label is enhanced.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting marks, and in particular relates to an anti-counterfeiting mark of organic photoluminescent material information and a preparation method thereof. Background technique [0002] Anti-counterfeiting has been a hundred years old by using excited fluorescent inks, especially infrared-excited inks and ultraviolet-excited inks have also been widely used in the anti-counterfeiting industry. The technology of sensory identification of authenticity seems simple and easy, but it is actually unreliable, because the human eye's color discrimination is actually very vague, and criminals can easily create imitations with similar colors that cannot be distinguished by human eyes. Goods come. Contents of the invention [0003] The object of the present invention is to provide an organic photoluminescent material information anti-counterfeiting label, which has high anti-counterfeiting exclusivity a...
