Embodiment 1

[0041] A specific embodiment of the anti-counterfeiting paper of the present invention is provided below, as figure 1 As shown, the anti-counterfeiting paper includes two layers of paper sheets 3 formed separately, and a fiber textile belt 2 is arranged in the two layers of paper sheets 3, and an anti-counterfeiting element 1 is arranged on the fiber textile belt 2, where the anti-counterfeiting element 1 It is a common magnetic anti-counterfeiting sheet, and the fiber textile belt 2 includes a wire mesh layer woven from nylon fibers with a melting point of 85°C. The nylon here is selected from nylon 6 with a low melting point commonly found in the market. Here, it is selected from South Korea. Nylon 6 imported by Hyosung. The textile fiber strip 2 forms a white watermark in the paper sheet 3 , and the security element 1 forms a black watermark in the paper sheet 3 .

[0042] The manufacture method of above-mentioned anti-counterfeiting paper, comprises the steps:

[0043] ①...

Embodiment 2

[0048] On the basis of the above embodiment 1, in order to form a stable white watermark effect after the fiber textile belt 2 is melted, the silk screen layer can be woven from silk threads of 50-1000 denier, preferably 200-500 denier, Select the silk thread of 300 deniers in the present embodiment; The thickness of described screen layer selects 5-100 micron, preferably 20-50 micron, selects 30 micron in the present embodiment; The mesh number of described silk screen layer is 10 order-200 Mesh, select 50 mesh in the present embodiment; The light transmittance of described screen layer is 20%-80%, selects light transmittance in the present embodiment 50%.

[0049] In addition, in this embodiment, fluorescent fibers are also woven into a part of the fiber textile belt 2 , forming a heterogeneous region with novel features that is different from ordinary paper.

[0050] The anti-counterfeiting paper described in this embodiment can be produced through the following steps,

[...

Embodiment 3

[0058] On the basis of the above embodiments, in order to ensure that the anti-counterfeiting element 1 is added to the paper page 3 to have a better black watermark effect, and the paper page 3 is smooth and beautiful after forming the paper, the thickness of the anti-counterfeiting element 1 is generally selected to be 10-100 micron, preferably 30-50 microns, the overall thickness of the anti-counterfeiting element 1 in this embodiment is 40 microns, and the anti-counterfeiting element 1 here has a sandwich structure, such as figure 2 As shown, the sandwich structure includes two base layers 4, 6 and a machine-readable material layer 5 between the base layers 4, 6, and the machine-readable material layer 5 includes an amorphous soft magnetic film with a thickness of 20-300 nanometers , the film has uniaxial magnetic anisotropy in the film plane, and has a machine-readable large Barkhausen effect along the direction of its easy magnetization axis.

Abstract

A security paper comprises at least two layers of independently molded paper pages. A fiber textile belt is arranged between the two paper pages and provided with a security element; the fiber textile belt comprises a silk screen layer woven from a hot melting material with melting point at 50-100 DEG C; the fiber textile belt forms a white watermark on the paper page; and the security element forms a black watermark on the paper page. The invention solves technical problems in the prior art that a positioning security component addition method is not suitable for a molded security element and that security element addition using a water-soluble material as a carrier requires a long processing time and results in poor paper effect. The security paper provided by the invention is particularly suitable for the production of valuable documents and security document.

Description

technical field [0001] The invention relates to an anti-counterfeit paper for producing valuable documents and a method for producing the anti-counterfeit document, in particular to an anti-counterfeit paper with anti-counterfeit features. Background technique [0002] In the production of security documents (such as banknotes, passport ID cards, etc.), in order to improve their anti-counterfeiting performance, a more effective measure is to form a heterogeneous area with novel features and ordinary paper. Common methods include using security lines and anti-counterfeiting labels. And add special fibers, anti-counterfeiting sheets, etc. [0003] In order to form a heterogeneous area with anti-counterfeiting features, the patent document CN1021971722A proposes a multiple anti-counterfeiting watermark paper and its manufacturing method. The watermark paper has patterns, patterns or lines formed by weaving or embroidering non-water-soluble fibers or anti-counterfeiting fibers. ...
