Problems solved by technology

[0002] As a basic anti-counterfeiting material for papermaking, colored anti-counterfeiting fiber has been widely used in the field of anti-counterfeiting paper, such as banknotes, securities, anti-counterfeiting manual labels, etc., but the problem that has been difficult to solve is that it is easy to imitate its visual characteristics when printing colored thin lines. Especially in some occasions where damage to the paper is not allowed, counterfeit printed thin lines are easy to get away
In addition, another problem of the colored anti-counterfeiting fibers randomly distributed on the paper is that it pollutes the paper surface and affects the aesthetic effect of the entire design pattern

Embodiment 1

[0039] Example 1: The cross-sectional shape of the anti-counterfeiting fiber shown in Figure 1-1 and Figure 1-2 is circular, the outer layer material 1 and the inner layer material 2 are concentric structures, and the outer layer material 1 is color A, such as containing titanium The organic material of white powder, the inner layer material 2 is color B, the color B and color A have obvious visual difference, and the color B is transparent, for example, the inner layer material 2 is a transparent red organic material, the thickness of the outer layer material 1 is the same as that of titanium The concentration of the white powder can just cover the red color of the inner layer material 2 to ensure that the fiber is copied into the white pulp layer, and when the fiber is observed in the paper under the condition of reflected light (sunlight), it is white or the same or similar to the color of the paper surface Excessive coverage will affect the color of the inner layer material...

Embodiment 2

[0042] Embodiment 2: The cross-sectional shape of the anti-counterfeiting fiber described in Fig. 2-1 and Fig. 2-2 is flat, the cross-sectional shape of the inner layer material 2 is flat strip shape, and the outer layer material 1 and the inner layer material 2 are coaxial structures , other material characteristics are the same as those of the above-mentioned embodiment 1.

Embodiment 3

[0043] Embodiment 3: The cross-sectional shape of the anti-counterfeiting fiber shown in Fig. 3-1 and Fig. 3-2 is circular, and the cross-sectional shape of the inner layer material 2 is a circle composed of a semicircle first part 3 and a semicircle second part 4 juxtaposed , the semicircular first part 3 and the semicircular second part 4 have the same color and have different thermal shrinkage rates, which can ensure that the fibers are easy to bend, and other material characteristics are the same as in the above-mentioned embodiment 1.

Abstract

The invention relates to an anti-falsification fiber and an anti-falsification paper with the anti-falsification fiber, and the anti-falsification fiber which is formed by at least outer material (1) and internal material (2) through composition, and the internal material (2) is coated by the outer material (1); the invention is characterized in that: the color of the outer material (1) is color A, and the color of the internal material (2) is color B; an obvious vision difference exists between the color A and the color B, and an obvious vision difference also exists between the color of the reflected light observation of the anti-falsification fiber arranged in a pulp layer and the color of the penetration observation of the anti-falsification fiber after the anti-falsification fiber entering the paper pulp layer. The invention has the advantages of eliminating the passing-off of the printing technology efficiently, and avoiding the pollution on the paper surface in the reflected light observation.

Description

technical field [0001] The invention relates to an anti-counterfeiting fiber and anti-counterfeiting paper containing the anti-counterfeiting fiber, in particular to an anti-counterfeiting fiber and anti-counterfeiting paper containing the anti-counterfeiting fiber which have obvious visual differences when observed by reflected light and transmitted light. Background technique [0002] As a basic anti-counterfeiting material for papermaking, colored anti-counterfeiting fiber has been widely used in the field of anti-counterfeiting paper, such as banknotes, securities, anti-counterfeiting manual labels, etc., but the problem that has been difficult to solve is that it is easy to imitate its visual characteristics when printing colored thin lines. Especially in some occasions where damage to the paper is not allowed, counterfeit printed thin lines are easy to get away. In addition, another problem of the colored anti-counterfeiting fibers randomly distributed on the paper sur...
