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 surfaces (3) have concave-convex sheltering structure, and at least 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 surfaces (3), resulting that the color patterns (A, B) can be seen from the surface (1') of the anti-forge material (1) 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.

L'invention concerne un matériau anti-contrefaçon. Les anti-fibres (2) sont réparties sur le matériau anti-contrefaçon. Des surfaces partielles (3) des fibres anti-contrefaçon (2) sont situées à la surface (1) du matériau anti-contrefaçon (1), où lesdites surfaces partielles (3) ont une structure de protection concave/convexe, et au moins deux motifs de couleur (A, B) sont répartis sur les surfaces. Lesdits au moins deux motifs de couleur (A, B) ont une différence visuelle distincte sur lesdites surfaces partielles (3), avec pour résultat que les motifs de couleur (A, B) sont visibles de la surface (1') du matériau anti-contrefaçon (1) respectivement, vus d'un angle différent. Du fait de la différence visuelle selon la présente invention formée en protégeant les motifs répartis sur les surfaces partielles (3) des fibres anti-contrefaçon (2) dans le matériau anti-contrefaçon avec la structure de protection concave/convexe, l'impression exacte est incapable d'imiter la structure en trois dimensions. C'est la raison pour laquelle la présente invention est capable d'empêcher efficacement l'imitation de l'impression.
