Abstract:
A color shifting security device has a Fabry-Perot type structure wherein a dielectric layer (702) is disposed between a reflector (701) and an absorbing layer (703). The absorber and reflector layers may be conforming and the dielectric layer therebetween is non-conforming, filling the regions in the micro structured adjacent absorbing or reflecting layer, at least one of which has a microstructure therein or thereon. By having the dielectric layer not conform to the microstructure it is next to, its thickness varies in cross section, which allows for different colors to be seen where the thickness (t1) varies.
