ABSTRACT:
A thermochromic ink composition comprises at least one thermochromic optical-state change material, at least one thermally responsive pH modifier, and at least one base and at least one binder material. The quantity of the thermally responsive pH modifier is less than or equal to about 0.25 milli moles based on the amount of optical-state change material. The 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 comprise a nitro dye. A thermochromic coating composition formed using the thermochromic ink composition is also disclosed.
