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 with figure 2 The front view of the upper surface and the lower surface of a security fiber are shown separately. figure 1 The color feature of the upper surface 1 displayed is a single color, such as red, figure 2 The displayed color feature of the lower surface 2 is another single color, such as blue.

Embodiment 2

[0030] Example 2: image 3 with Figure 4 The front views of the upper surface 1 and the lower surface 2 of another anti-counterfeiting fiber are shown respectively. image 3 The displayed color feature of the upper surface 1 is a single color, such as red, Figure 4 The color feature of the bottom surface 2 is two color segments 2 composed of two colors 1 And 2 2 The two colors can be two colors 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 another color such as blue.

[0031] Example 1 and Example 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 invention objective of the present invention, the color characteristics of the upper surface 1 and the lower surface 2 of a single anti-counterfeiting fiber The color characteristics must be different.

Embodiment 3

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

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] Colored fibers have been added to paper to make anti-counterfeiting paper for more than one hundred years. The existing 100 US dollar banknotes, new version 100 yuan, 20 yuan RMB, new version 1,000 Hong Kong dollars, Swiss francs, Dutch guilders, Indonesian dollars, Austrian shillings The anti-counterfeiting technology of adding colored fibers in the papermaking process is adopted for the banknote printing papers used in other industries and a large number of securities papers. However, the above-mentioned added fibers have only one color on one fiber. The production itself is not difficult, but its fatal disadvantage is: from the visual effect of monochromatic fibers, counterfeiters are very easy to imitate realistically with monochro...
