摘要： An integrated security structure is provided employing an external source of energy to change the appearance of the structure rendering the structure more challenging to duplicate due to its complexity. The security structure includes a substrate forming part of a bank note, identification document, or other security device; an active device within the substrate changing color between at least two colors wherein a color of the substrate surrounding the active device matches one of the at least two colors to form a metameric device. At least one Interference Security Image Structure (ISIS) is configured to be metameric with a bleached state of the active device and is therefore invisible at normal incidence. Another ISIS is metameric with the colored state of the electrochromic device and consequently becomes invisible during coloration. When the whole device is tilted, both ISIS's change color while the rest of the device essentially remains the same.

摘要： An interference filter having a plurality of layers and a spectrum as a function of angle of observation is combined with a metameric element adjacent the interference filter and appearing to have a same color as the interference filter at at least one angle of observation and a contrasting color as said interference filter at least one other angle of observation. A plurality of interference filter layers, including a metallic layer, can be provided on a support structure for the layers. The support structure is then adapted to allow the layers to be seen from a top and a bottom side, with the layers being adapted to have different spectra as a function of angle of observation in reflection and transmission.
