A security sign with several degrees of protection comprises a polymeric layer, where a hidden polarizing image is formed as separate layer areas with reduced anisotropy, where the anisotropic properties of the mentioned layer are formed by microlines, and a reflecting layer. The sign comprises at least one polymeric layer area with hidden fluorescent polarization image and a paint nonreflecting layer, and the reflecting layer is made at the back of the hidden polarization image, the paint nonreflecting layer is arranged at the back of the mentioned area of the hidden fluorescent polarization image. |
