Problems solved by technology

The anti-counterfeiting features embodied by the sheet-shaped anti-counterfeiting material are relatively single, and counterfeit products are prone to appear, and the sheet-shaped anti-counterfeiting material will affect the consistency and stability of its anti-counterfeiting features due to the shedding of the anti-counterfeiting material during production and use, resulting in detection, Difficulty in authenticity identification
[0005] To sum up, the field lacks a method that can reflect more anti-counterfeiting information, and can ensure the consistency and stability of the anti-counterfeiting information on the sheet-shaped anti-counterfeiting material during production and use, and achieve the purpose of preventing counterfeit products from appearing. anti-counterfeiting technology

preparation example Construction

[0069] The preparation method of described sheet anti-counterfeiting material comprises the steps:

[0070] The sheet-shaped anti-counterfeiting material is obtained by cutting a composite rod-shaped material composed of a plurality of strip-shaped materials containing anti-counterfeiting substances along the radial cross-sectional direction, and the cutting direction is aligned with the length direction of the composite rod-shaped material. angle.

[0071] In a specific embodiment, among the plurality of long strip materials constituting the composite rod-shaped material, anti-counterfeiting substances with anti-counterfeit information are added to at least part of the long strip materials, preferably by adding stock solution.

[0072] In a specific embodiment, in the method of adding the stock solution, at least one of the strip-shaped materials is made of fluid stock solution, and the anti-counterfeiting substance is contained in the stock solution of the strip-shaped mater...

Embodiment approach

[0098] In the above-mentioned sheet-shaped anti-counterfeiting material and its manufacturing method, wherein, the sheet-shaped anti-counterfeiting material is cut along the radial cross-sectional direction by a composite rod-shaped material composed of a plurality of strip-shaped materials carrying anti-counterfeiting features. The cutting direction has a certain included angle with the length direction of the composite rod-shaped material. as attached figure 1 Shown: the angle θ between the cutting direction and the length direction of the composite rod-shaped material can be any value greater than 0° and less than 180°, and the preferred value of the angle θ ranges from 60° to 120°.

[0099] In the above-mentioned sheet-shaped anti-counterfeiting material and its manufacturing method, the composite rod-shaped material is composed of multiple (at least two) strip-shaped materials.

Abstract

The present invention provides a sheet-like anti-counterfeiting material which comprises a composite rod material obtained by compounding a plurality of long strip materials containing an anti-counterfeiting material, the composite rod material is obtained by cutting along radial cross section direction, and an angle is between the cutting direction and the length direction of the composite rod material. The present invention provides an anti-counterfeiting technology which can reflect more anti-counterfeiting information, can guarantee the consistency and stability of the anti-counterfeiting information on the sheet-like material in the production and using process, and can achieve the purpose of prevention of counterfeits.

Description

technical field [0001] The invention relates to a sheet-shaped anti-counterfeiting material and a manufacturing method thereof, belonging to the field of anti-counterfeiting technology. The invention also relates to a security paper containing the sheet-shaped anti-counterfeit material and an anti-counterfeit object manufactured by using the anti-counterfeit paper. Background technique [0002] For the printing of anti-counterfeit objects such as banknotes, securities, passports, bills, certificates, etc., anti-counterfeit paper is mostly used as the printing substrate. The technology of adding anti-counterfeiting materials such as powders, fibers, and sheets carrying anti-counterfeiting information in the manufacturing process of anti-counterfeiting paper has been widely used. [0003] It is a known technology to add sheet-shaped anti-counterfeiting material in anti-counterfeiting paper as an anti-counterfeiting measure. Compared with powder and fibrous anti-counterfeitin...
