Abstract

Un colorant électrostatique liquide comporte essentiellement un solvant hydrophobe inerte dans lequel sont dispersées des particules de matière tinctoriale, ces particules étant pratiquement insolubles dans le solvant et étant solubles dans une surface polymère hydrophobe à des températures supérieures à la température de ramollissement de cette dernière, ainsi qu'un agent de modulation de fonçage qui de préférence se répartit sur les particules de matière tinctoriale. Est également décrit un procédé d'impression électrostatique consistant à mettre en contact avec la surface polymère hydrophobe d'une feuille un colorant électrostatique liquide imagé du type décrit, la surface polymère hydrophobe présentant une température de ramollissement, et à chauffer la surface polymérique à au moins la température de ramollissement précitée. On obtient ainsi des images couleur très nettes. La reproduction d'images en couleur pure à partir d'une mémoire d'ordinateur est une caractéristique particulière de la présente invention.
