More Information
Summary: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. L'invention concerne une composition d'encre électrostatique comprenant : a) des particules pouvant être chargées comprenant une résine ; b) un directeur de charge comprenant un sel sulfosuccinate de la formule générale M'Am, dans laquelle M' est un métal, m est la valence de M', et A est un ion de la formule générale (I) : (I) [R3-O-C(O)CH2CH(SO3)C(O)-O-R4]- dans laquelle chacun de R3 et R4 est un groupe alkyle ; et c) une fraction naphthalène-sulfonate éventuellement substituée. L'invention concerne également un procédé de fabrication d'une composition d'encre électrostatique et un support imprimé ayant une composition d'encre électrostatique imprimée dessus.
