FIELD: polygraphy.
SUBSTANCE: provided is a security device comprising: a transparent layer having a first optically variable effect generating relief structure formed in a surface thereof; a reflection enhancing body extending over the first relief structure and following the contour of the first relief on a first side of the reflection enhancing body, and a second optically variable effect generating relief structure formed in a second side of the reflection enhancing body. Reflection enhancing body comprises at least a first reflection enhancing layer defining the first and/or second sides of the reflection enhancing body and comprises a binder having reflective particles dispersed therein.
EFFECT: when the device is viewed through the transparent layer, the optically variable effect of the first relief structure is visible and when the device is viewed from the other side, the optically variable effect of the second relief structure is visible.
