Abstract
A dual color electronically addressable ink includes a non-polar carrier fluid; a first colorant of a first color; and a second colorant of a second color that is different than the first color. The first colorant includes a first particle core, and a first functional group attached to a surface of the particle core. The first functional group is capable of carrying a positive charge and is chosen from a base or a salt of the base. The second colorant includes a particle core, and a second functional group attached to a surface of the particle core. The second functional group is capable of carrying a negative charge and is chosen from an acid or a salt of the acid. The ink further includes an additive chosen from polyhydroxystearic amide salt, polyhydroxystearic acid, aromatic butyric acid, and combinations thereof.
