Problems solved by technology

This is not only inconvenient, but also commodities such as banknotes and securities cannot be destroyed, so its anti-counterfeiting effect is greatly limited, and counterfeiters often use thin lines to imitate it, and it is easy to get away with it

Embodiment Construction

[0028] figure 1 It shows that an enlarged anti-counterfeit fiber 2 is distributed in the anti-counterfeit material 1, part of the surface 3 of the anti-counterfeit fiber 2 is presented on the surface 1' of the anti-counterfeit material, and part of the surface 3 has a concave-convex shielding structure. The concave-convex shielding structure in this figure is formed by The cross-section 4 of the anti-counterfeiting fiber 2 is composed of triangular elements. The vertex angle of the triangular elements and the surface where the hypotenuses are located constitute a convex shielding structure. The surfaces 3' and 3" where the two hypotenuses are located form the surface 3. The characteristic pattern A is distributed on the surface 3", and the characteristic pattern B is distributed on the surface 3". When observing part of the surface 3 from different angles on the surface 1' of the anti-counterfeiting material 1, the characteristic patterns A and B can be seen respectively, such ...

Abstract

An antifraud material is featured as distributing antifraud fibre on partial surface of the antifraud material, having concave-convex sheltering structure of the partial surface, setting two-character drawing A and Bon the structure to have obvious visual difference, seeing character drawing A and B separately at time of viewing the partial surface from different angles.

Description

technical field [0001] The invention relates to an anti-counterfeit material such as anti-counterfeit paper or anti-counterfeit film or anti-counterfeit packaging, especially an anti-counterfeit material distributed with anti-counterfeit fibers. Background technique [0002] It has been nearly a hundred years since colored fiber was added to paper to make anti-counterfeit paper, and it is still used in banknotes in many countries, and some securities, tax invoices, product brochures, and printed labels are also used. To sum up, the anti-counterfeiting fiber has a single monochromatic fiber. What is described in Chinese patent 02168121.0 "an anti-counterfeiting fiber" is a single multi-color section fiber, that is, a fiber has at least two colors along the length direction. What is also described in Chinese patent 02170092.4 "An anti-counterfeiting fiber and anti-counterfeiting paper using the fiber" is a fiber with different colors on the front and back sides, that is, the ...
