Patent abstract
A dispersion containing a coloring agent particle is mixed in a dispersion of a radical polymerizable monomer, and a reducing agent containing an iron(II) salt is added in the presence of a polymerization initiator to polymerize the dispersed radical polymerizable monomer by the action of a generated radical, thereby not only forming a binder resin fine particle but coagulating the binder resin fine particle and the coloring agent particle to form a coagulated particle.
