This invention relates to a process for preparing dispersible organic pigments by (a) milling a mixture containing (1) one or more organic pigments, (2) at least about 1 % by weight, relative to the organic pigment, of one or more aromatic polyalkylene oxide dispersants, (3) 0 to about 10 parts by weight, relative to the organic pigment, of a milling liquid in which the organic pigment is substantially insoluble, (4) 0 to about 50% by weight, relative to the organic pigment, of one or more milling additives other than dispersant (2), and (5) 0 to about 20% by weight, relative to the organic pigment, of one or more surface treatment additives; (b) optionally, adding to the milled pigment (6) one or more liquids in which the organic pigment is substantially insoluble in amounts such that the total solids content is not reduced below about 10%, and (7) one or more multivalent metal salts and/or one or more quaternary ammonium salt; and (c) isolating the milled organic pigment
La présente invention concerne une méthode de préparation de pigments organiques dispersibles par a) broyage d'un mélange contenant (1) un ou plusieurs pigments organiques, (2) au moins environ 1 % en poids, par rapport au pigment organique, d'un ou plusieurs dispersants d'oxyde de polyalkylène aromatiques, (3) 0 à 10 parties en poids, par rapport au pigment organique, d'un liquide de broyage dans lequel le pigment organique est essentiellement insoluble, (4) 0 % à environ 50 % en poids, par rapport au pigment organique, d'un ou plusieurs additifs de broyage autres que le dispersant (2), et (5) 0 à environ 20 % en poids, par rapport au pigment organique, d'un ou plusieurs additifs de traitement de surface; b) facultativement, ajout au pigment moulu (6) d'un ou plusieurs liquides dans lesquels le pigment organique est essentiellement insoluble en quantités telles que la teneur totale en solides n'est pas réduite sous environ 10 %, et (7) un ou plusieurs sels métalliques multivalents et/ou un ou plusieurs sel d'ammonium quaternaire et c) isolation du pigment organique moulu.
