    CPC classification number: C09D11/50

    Abstract: A thermochromic ink composition comprises at least one thermochromic optical-state change material, at least one thermally responsive pH modifier, at least one solvent, and at least one binder material, wherein the thermochromic ink composition has a viscosity between about 0.1 centipoise (cPs) and about 10,000 cps, and a maximum optical absorbance in a range from about 200 nm (nanometers) to about 800 nm, and wherein the thermochromic ink composition is capable of transforming from a first optical state to a second optical state upon exposure to a thermal stimulus. The thermochromic ink composition may be used to deposit a thermochromic coating composition which may be used as part of an anti-theft system for optical articles. Methods for thermal activation of the compositions are also provided.
