Publication number: 20090215620Abstract: 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.Type: ApplicationFiled: March 13, 2009Publication date: August 27, 2009Applicant: GENERAL ELECTRIC COMPANYInventors: James Anthony Cella, David Gilles Gascoyne, Ben Purushotam Patel, Paul Michael Smigelski, JR., James Mitchell White, Gregory Allen O'Neil, Andrea Jeannine Peters, Matthew Jeremiah Misner, Trevor James Dale, Whitney Jeanne Olson, Marc Brian Wisnudel
