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...

Examples

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.

[0100] In the above-mentioned sheet-like anti-counterfeiting material and its manufacturing ...

Embodiment 1

[0121] as attached figure 2 As shown, the cross-sectional shape is a right-angled triangle, and the length of the right-angled side is 2 millimeters. The strip-shaped material 1 containing colorless red fluorescent anti-counterfeiting substance (made by spinning with colorless red fluorescent pigment in molten PVA), the cross-sectional shape It is circular, with a diameter of 2 mm, and contains magnetic powder strip material 2 (made by adding magnetic powder to molten PVA), with a circular cross-sectional shape, with a diameter of 3 mm, containing metal powder The strip-shaped material 3 (made by spinning after adding nickel powder in the molten PVA), the cross-sectional shape is an equilateral triangle, and the side length is 3 millimeters, and contains the strip-shaped material 4 of colorless blue fluorescent anti-counterfeiting substance ( It is made by adding colorless blue fluorescent pigment in molten PVA and spinning), the cross-sectional shape is square, and the side ...
