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 can almost get away with printing thin lines to imitate

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 color pattern A is distributed on the surface 3", and the color 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 color patterns A and B can be seen respectively, such as from a If you observe f...

Abstract

The present invention provides anti-fake material with distributed anti-fake fiber and the anti-fake fiber has partial surface exhibited on the surface of the anti-fake material. The anti-fake material features that the partial surface possesses uneven shielding structure and at least two distributed color patterns, A and B, with obvious visual difference and capable of being watched separately when observed in different angles. Owing to the visual difference caused by the stereo fiber structure and incapable of being simulated via printing, the present invention can avoid printing simulation effectively.

Description

technical field [0001] The invention relates to an anti-counterfeit material such as anti-counterfeit paper or film or anti-counterfeit packaging, especially an anti-counterfeit material distributed with anti-counterfeit fibers and whose visual characteristics cannot be imitated by printing. Background technique [0002] It has been nearly a hundred years since colored fibers were added to paper to make anti-counterfeiting paper, and it is still used in banknotes in many countries. Some securities, tax invoices, product brochures, and printed labels are also used; especially fluorescent fibers, it is also used in paper money. Used in almost all banknotes. To sum up, anti-counterfeiting fibers usually have a single monochrome fiber and a single multicolor 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 Chi...
