ABSTRACT:
A dye composition prepared by polymerizing an unsaturated monomer in the presence of a quinoneimine dye and an azo initiator in amounts expressed by x.gtoreq.5 and y.gtoreq.0.33x.sup.1.2 wherein x is the amount of the quinoneimine dye in % by weight based on the unsaturated monomer, and y is the amount of the azo initiator in % by weight based on the unsaturated monomer. The composition is useful for preparing toners for developing electrostatic images because of its outstanding charge control effect and also for preparing electrostatic coating powder compositions.
