Problems solved by technology
[0007] However, such as listed above, the prior art composite fibers, fluorescent silicon nanoparticles, micro-dots or micro-mark shapes and random distribution as anti-counterfeiting means are not the effect that can prevent others from forging as described in the open text. With the advancement of science and technology, these technical means can be imitated cheaply. The only thing that cannot be imitated is the background database described in prior art 3, but the background data is not safe. Enterprise databases are easily attacked by hackers, and communication security is required. Still not ideal
Existing technology 3 and prior art 4 can solve most of the anti-counterfeiting needs. However, anti-counterfeiting materials composed of a single material are easy to be imitated, and the uniform gray tone has no sense of hierarchy and three-dimensionality, which still cannot meet high-end needs. Therefore, it is necessary to constantly innovate and improve

Embodiment Construction
[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0050] refer to figure 1 , figure 2 , figure 2 Yes figure 1 In the sectional view of plane A-A, the first embodiment of the present invention is an anti-counterfeiting material, which includes a sheet-shaped monocrystalline silicon module 001, and the monocrystalline silicon module 001 has a hollowed out area. The anti-counterfeiting material also includes a metal module 002, and the metal module 002 Inlaid in the hollow area. The metal module 002 refers to the sum of each sub-module composed of metal in a unit of anti-counterfeiting material 000, each sub-module is discretely distributed, and the metal module 002 is composed of three sub-modules to form the string "Red ", it should be understood that the metal module 002 can be a graphic or a character, and the metal module 002 can also be composed of a plurality of sub-modules to form a set of graphic...

Abstract
The invention relates to the anti-counterfeit technology, in particular to a multi-material and three-dimensional anti-counterfeit material and a production method thereof. The anti-counterfeit material comprises a sheet monocrystalline silicon module provided with a hollow area. The anti-counterfeit material further comprises a metal module embedded into the hollow area. The production method of the anti-counterfeit material includes: plating an adhering layer on a glass substrate, plating a sacrificial layer, plating a monocrystalline silicon layer, coating light-curing adhesives, exposing, developing, cleaning, etching the monocrystalline silicon layer, coating the adhesives again, exposing, developing, cleaning, plating the metal module, cleaning the light-curing adhesives, etching the sacrificial layer, and cleaning and filtering.
Description
technical field [0001] The invention relates to anti-counterfeiting technology, in particular to an anti-counterfeiting material and a preparation method thereof. Background technique [0002] In the anti-counterfeiting technology of the prior art, watermarks, colored fibers, fluorescent ink printing, shapes and random distribution of micro-dots or tiny marks are mostly used as anti-counterfeiting means. [0003] For example, prior art 1, Chinese patent document CN102108653A, discloses a sheet-shaped anti-counterfeiting material, the sheet-shaped anti-counterfeiting material adopts a special-shaped structure other than a regular quadrilateral; and the sheet-shaped anti-counterfeiting material is composed of the following layered structure: paper A quality anti-counterfeiting carrier layer, wherein the paper-based anti-counterfeiting carrier is paper manufactured by compounding at least two kinds of fibers; and an anti-counterfeiting layer. Also disclosed are a preparation m...
