Abstract

A planar security device suitable for use in a security document comprises a substrate 2, a first fluorescent layer 3 on a first side, a layer of UV absorbent material 4 on the first fluorescent layer 3 and a second fluorescent layer 5 on the UV absorbent layer 4. When the device is viewed from the first side in transmitted UV light, the light will pass through the substrate 2 and illuminate the first fluorescent layer 3. But not the second 5 because of the absorbent layer 4. When viewed from the first side in reflected UV light the second fluorescent layer 5 will fluoresce but not the first layer 3. In use when the device is viewed from the first side in first transmitted and then reflected UV light, the fluorescence will appear to switch from the colour of the first fluorescent layer 3 to that of the second layer 5.
