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