Example Embodiment

[0044] Example one:

[0045] In this example, an invisible fluorescent ink anti-counterfeiting label structure with multi-directional and different patterns is as follows figure 1 Shown. From bottom to top, it includes liner layer 11, fluorescent ink layer 12, fluorescent ink layer two 13, prism glass layer 14, photonic crystal layer 15 and photonic crystal layer two 16. In this example, photonic crystal layer 15 and The second photonic crystal layer 16 is respectively coated on the same parallel surface of the prism glass layer 14 by physical vapor deposition, and is distributed in a periodic shape.

[0046] Such as figure 2 As shown, the photonic crystal layer 15 is made of MgF 2 And ZrO 2 Composition, of which MgF 2 The thickness is 40 nanometers, ZrO 2 The thickness of the two materials is 30 nanometers, and the two materials are distributed according to the quasi-periodic Fibonacci sequence (FB sequence for short), and the structure is as image 3 Shown.

Abstract

The invention discloses a multi-way invisible fluorescent ink anti-fake label with different patterns, and belongs to the field of anti-fake technology. The anti-fake label comprises a lining layer, a fluorescent ink layer I, a fluorescent ink layer II and a prism glass layer from bottom to top in sequence, wherein a photonic crystal layer I and a photonic crystal II are arranged on the prism glass layer. The anti-fake label has the characteristics of high elusive capability, imitation difficulty, multi-way display of different patterns and the like; and when the multi-way invisible fluorescent ink anti-fake label is used for commodity anti-fake, the elusive capability and the imitation difficulty of the invisible ink anti-fake label are enhanced, and the applicability of the anti-fake label is improved.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and in particular relates to an anti-counterfeiting label with multi-directional and different patterns of invisible fluorescent ink. Background technique [0002] In the process of commodity circulation, counterfeit and forged commodities have seriously affected the normal order of production and sales of enterprises. Existing anti-counterfeiting technologies, including laser anti-counterfeiting labels, digital anti-counterfeiting inquiries, electronic labels, and anti-counterfeiting packages, all have the characteristics of easy imitation and poor concealment. [0003] With the rapid development of science and technology, physical anti-counterfeiting technologies such as laser anti-counterfeiting and barcodes are very easy to be copied, and ordinary consumers generally cannot recognize the authenticity of signs such as laser anti-counterfeiting. On the other hand, high-quality prod...
