摘要：
A photobleachable ink composition having: at least one light-sensitive optical-state change material; at least one bleaching accelerant; 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 change from a first optical state to a second optical state upon exposure to light. The composition may also include a plasticizer.
