Patent ID: 7760614

Claim:
An optical article configured for transformation from a pre-activated state of functionality to an activated state of functionality, comprising: at least one data side; an optical data layer for storing data; an electrically responsive layer having a first surface and a second surface, wherein the electrically responsive layer is characterized by an optical absorbance in the range of about 200 nanometers to about 800 nanometers, the electrically responsive layer being configured to transform from a first optical state to a second optical state upon exposure to an external stimulus, and being capable of irreversibly transforming the optical article from the pre-activated state of functionality to the activated state of functionality, wherein the electrically responsive layer comprises: a binder; an electrically responsive material; an electrolyte; and at least two electrodes in electrical contact with the electrically responsive layer, wherein the electrodes are in electrical communication with the same surface of the electrically responsive layer.
