  • Patent number: 8361587
    Abstract: An optical article comprising a primary mark disposed on the optical article and a secondary mark disposed on the optical article in close proximity to the primary mark. The primary mark comprises a first optical-state change material and the secondary mark comprises a second optical-state change material. The optical article is transformed from a pre-activated state to an activated state when a localized authorized activation method is used that selectively activates the primary mark. The optical article is transformed from a pre-activated state to an deactivated state when a non-localized unauthorized activation method is used that activates the secondary mark along with the primary mark resulting in the second optical-state change material undergoing a reverse color change when compared to the first optical-state change material. An optical article with a single mark including multiple color change optical-state change material is also disclosed.
