Title
(EN) LIQUID ELECTROPHOTOGRAPHIC INK COMPOSITION
(FR) COMPOSITION D'ENCRE ÉLECTROPHOTOGRAPHIQUE LIQUIDE
Abstract
(EN)
Herein are describes liquid electrophotographic ink compositions and methods for producing liquid electrophotographic ink composition. The liquid electrophotographic ink compositions may be producing using a method comprising: grinding a resin and a pigment to form a paste; reacting an aluminium C12-24 carboxylate and a molecule having a molecular weight (Mw) of less than about 1000 and comprising a functional group selected from an amide, an ester, a carboxylic acid, an amine, an imide and combinations thereof to form a charge promoting component; and combining the paste and the charge promoting component to form a liquid electrophotographic ink.
(FR)
L'invention concerne des compositions d'encre électrophotographique liquide et des procédés de production d'une composition d'encre électrophotographique liquide. Les compositions d'encre électrophotographique liquide peuvent être produites à l'aide d'un procédé consistant : à broyer une résine et un pigment afin de former une pâte ; à faire réagir un carboxylate en C12-24 d'aluminium et une molécule ayant un poids moléculaire (Mw) inférieur à environ 1 000 et comprenant un groupe fonctionnel choisi parmi un amide, un ester, un acide carboxylique, une amine, un imide et leurs combinaisons afin de former un constituant d’activation de charge ; et à combiner la pâte et le constituant d’activation de charge afin de former une encre électrophotographique liquide.
