    摘要: A pigment dispersant contains the following component (a) alone or the following components (a) and (b) in combination:Component (a): a composite pigment formed of a diketopyrrolopyrrole pigment having a sulfonic group and another diketopyrrolopyrrole pigment having no sulfonic group, wherein the number of sulfonic group per molecule of the diketopyrrolopyrrole pigments in the composite pigment is from 0.05 to 0.5; andComponent (b): a pigment other than the component (a), wherein the pigment has a sulfonic group or its metal salt, ammonium salt or amine salt.Also disclosed are a colored composition for color filters, a process for the fabrication of a color filter, the color filter fabricated by the process, an image display device including the color filter, and an information communication equipment including the image display device. These colored composition, process, color filter, image display device and information communication equipment all make either direct or indirect use of the pigment dispersant.

    摘要: Dispersants for organic pigments comprise compounds represented by the following formula (I): wherein X and X′ each independently represent H, OH, alkoxy, primary, secondary or tertiary amino, or acylamino; Y represents an anthraquinonylamino, phenylamino or phenoxy group having H, OH, alkoxy, primary, secondary or tertiary amino, or acylamino at the 4-position or 5-position; A and B each independently represent alkyl, cycloalkyl or aryl, and at least one of A and B has at least one substituent group containing a basic nitrogen atom; and Z represents H, CN, halogen, alkyl, alkoxy, NO2, benzoylamino or 3-benzoyl, and the 3-benzoyl group may be fused together with X to form an acridone ring. Pigment dispersions making use of the above dispersants are suited for the production of writing or recording pigment inks.
