Problems solved by technology

[0003] The invention solves the defect that the visual features of colored fibers in the existing anti-counterfeiting paper added with colored fibers are easily counterfeited by printing methods, and designs an anti-counterfeiting fiber that prevents printing methods from imitating the visual features of colored fibers and anti-counterfeiting paper using the anti-counterfeiting fiber. It can make it difficult for counterfeiters to counterfeit by printing, and at the same time, it is easy to be directly identified by the naked eye non-destructively

Embodiment 1

[0029] Example 1: figure 1 and figure 2 A front view of the upper and lower surfaces of an anti-counterfeiting fiber is shown, here figure 1 The color of the displayed upper surface 1 is characterized by a single color, such as red, figure 2 The displayed color of the lower surface 2 is characterized by another single color, such as blue.

Embodiment 2

[0030] Example 2: image 3 and Figure 4 The front view of the upper surface 1 and the lower surface 2 of another security fiber are shown respectively, here image 3 The color of the displayed upper surface 1 is characterized by a single color, such as red, Figure 4 The color feature of the lower surface 2 is two color segments 2 composed of two colors 1 and 2 2 , the two colors can be two colors that are completely different from the red on the upper surface 1, such as yellow and blue, or one color can be red, and the other color can be other colors such as blue.

[0031] Embodiments 1 and 2 illustrate that no matter how the respective color characteristics of the upper surface 1 or the lower surface 2 change, to achieve the first inventive object of the present invention, the color characteristics of the upper surface 1 of a single anti-counterfeiting fiber and the lower surface 2 The color characteristics must be different.

Embodiment 3

[0032] Example 3: Figure 5 and Image 6 A front view of the front and back of a security paper using security fibers is shown, respectively. Figure 5 The front side of the anti-counterfeiting paper 3 is shown, and the color characteristic of the upper surface 1 of the anti-counterfeiting fiber 4 displayed on it is a single color, such as red, Image 6 The reverse side of the anti-counterfeiting paper 3 is shown, and the color characteristic of the lower surface 2 of the anti-counterfeiting fiber 4 displayed thereon is also a single color, but another color, such as blue, different from the red on the front side.

Abstract

An antiforge fibrk is disclosed, which features that it has opposite two surfaces with different colours. An antiforge paper using the said antiforge fibre features that one surface of the said antiforge filbre can be seen on one surface of the paper and another surface of the said antiforge fibre can be seen on another surface of the paper. Its advantage is high visually antiforge effect.

Description

Technical field: [0001] The invention relates to an anti-counterfeiting material and its products, in particular to an anti-counterfeiting fiber and an anti-counterfeiting document using the anti-counterfeiting fiber. Background technique: [0002] It has been more than 100 years of history to add colored fibers to paper to make anti-counterfeiting paper. The existing 100 US dollar banknotes, the new version of 100 yuan, 20 yuan, the new version of 1,000 Hong Kong dollars, Swiss francs, Dutch guilders, Indonesian currency, Austrian shilling The anti-counterfeiting technology of adding colored fibers in the papermaking process is used in the printing paper for other purposes and a large amount of paper for securities, but the fibers added above are all only one color on one fiber. It is not difficult to make itself, but its fatal disadvantage is: from the visual effect of monochromatic fibers, it is very easy for counterfeiters to imitate it realistically with monochromatic p...
