A security device comprises a transparent, coloured element (2) in a first region of the device and in a surface of which a first optically variable effect generating relief structure (21) is formed. A reflection enhancing layer (30) extends over the first optically variable effect generating relief microstructure (21) and follows the contour of the relief, the reflection enhancing layer also being provided in a second region of the device laterally offset from the first region. |
