摘要: Polymeric dyes that comprise (a) segments render the soluble or dispersible in hydrocarbon solvents and (b) impart color. The polymeric can be introduced into formed to form stable colored dispersions, which used as toners for electrophotography. In these toners, dye contains macromeric moieties solvents. may contain either a charge-directing chelating moiety surface-release promoting both of moieties.
