Patent ID: 8820793

Claim:
A security device, comprising: a first color-shifting layer; a second color-shifting layer having a reflective characteristic different than a reflective characteristic of the first color-shifting layer, the first and second color-shifting layers exhibiting a visible color at normal incidence; a first light absorbing layer between first surfaces of the first and second color-shifting layers such that a first region is formed where the first absorbing layer is not between the first and second color-shifting lavers and a second region where the first light absorbing layer lies between the first and second color-shifting layers; and a second light absorbing layer on a second surface of the second color-shifting layer, wherein the first absorbing layer has a color selected to substantially match a color of light reflected at a normal angle of incidence by the second color-shifting layer combined with the second absorbing layer so that when the security device is viewed at an angle which is away from the normal angle of incidence the first and second regions are of a color that is different to that observed at normal incidence for the respective region.
