摘要： A self-dispersing graft-copolymer capable of self-dispersion in a high-electrical insulating carrier liquid to form grains therein. The graft-copolymer is combined with a pigment or dye to provide a self-dispersing solid colorant, which is suitable as a toner or toner supply for a liquid developing agent for electrostatic photography. The colorant is also applicable to a printing ink, an ink for an ink-jet system or a coating paint composition. The colorant well self-disperses in a carrier liquid to form well dispersed grains therein without the necessity of mechanical dispersing means.

摘要： A non-aqueous dispersing agent comprising a graft copolymer is characterized in that monomer(s) to constitute the graft portion(s) of the graft copolymer is (are) at least one or more macromonomers each having a terminal polymerizable functional group and that the graft copolymer is substantially soluble in a high electric-resistance non-aqueous solvent having a dielectric constant of 3 or less and a volume specific resistance of 10.sup.9 .OMEGA.cm of more. The dispersing agent may sufficiently disperse any of a colorant of pigment or dye, a fixing resin-coated colorant or a fixing resin itself by wet-dispersion, and it has an excellent storage stability. The agent is therefore useful in a liquid developer for electrostatic photography or in a liquid developer for preparing printing plates.
