Abstract (en)
[origin: EP1793039A1] An anti-forge material is disclosed. Anti-fibers (2) are distributed on the anti-forge material. Part surfaces (3) of the anti-forge fibers (2) are located on the surface (1) of the anti-forge material (1), Wherein said part surface (3) have concave-convex sheltering structure, and at lease two color patterns (A, B) are distributed on the surfaces. Said at least two color patterns(A, B) have distinct visual difference on the said part surface (3), resulting that the color patterns(A, B) can be seen from the surface (1') of the anti-forge material respectively when observed from different angle. Due to the visual difference according to the present invention is formed by shielding the patterns distributed on the part surfaces(3) of the anti-forge fibers (2) in the anti-forge material with the concave-convex sheltering structure, the exact printing is unable to imitate the three-dimensional structure. Therefore the present invention is capable of preventing imitate of printing effectively.
