Beschreibung
Zusammenfassung:	An object of the present invention is to provide a dispersion composition which is free from the precipitation problem because of its improved dispersion stability, permits employment of various kinds of organic solvents and insoluble granular materials, is widely utilizable, and is useful as, in particular, a liquid developer or a jet printing ink, in which electrostatic force is utilized. The present invention provides a dispersion composition comprising a dispersion of a granular material in an organic solvent and further comprising a high-molecular weight compound having acidic groups and a high-molecular weight compound having basic groups, at least a part of said high-molecular compounds being insoluble in the organic solvent, and said high-molecular weight compounds being adsorbed on at least a portion of the granular material.
