Abstract:
Herein is disclosed an electrostatic ink composition comprising: a) chargeable particles comprising a resin; b) a charge director comprising a sulfosuccinate salt of the general formula M′Am, wherein M′ is a metal, m is the valence of M′, and A is an ion of the general formula (I): (I) [R3—O—C(O)CH2CH(SO3)C(O)—O—R4]− wherein each of R3 and R4 is an alkyl group; and c) an optionally substituted naphthalene-sulfonate moiety. Also disclosed is a method of manufacturing an electrostatic ink composition and a printed medium having printed thereon an electrostatic ink composition.
