Abstract
An electrically responsive ink composition comprising at least one electrically responsive optical-state change material, at least one electrolyte material, at least one solvent, and at least one binder material, wherein the ink composition has a viscosity between about 0.1 centipoise and about 10,000 centipoise, and a maximum optical absorbance in a range from about 200 nanometers to about 800 nanometers; and wherein the ink composition is capable of transforming from a first optical state to a second optical state upon exposure to an electrical stimulus. The electrically responsive ink composition may be used to deposit an electrically responsive coating composition, which may be used as part of an anti-theft system for optical articles. Articles comprising electrically responsive coating compositions are also disclosed, as are methods for activation.
