Abstract

PURPOSE: An inorganic dispersant and black colorant are firmly bound on the surface of polymer particles with ionic linkages, thus fine spherical polymer particles containing black colorant and having uniform particle size distribution is produced.
CONSTITUTION: To a polymerizing monomer such as styrene or acrylonitrile, which is anionically or cationically charged by adding 0.1W5 wt% of a cationically polymerizing monomer, an organic amine hard soluble in water, or anionically polymerizaing monomer, are added (B) 0.1W2 wt% of inorganic dispersant having the charge opposite to the monomer (A) as coloidal silica or alumina, and (C) 0.1W 60 wt% of a black colorant as carbon black, or black direct dye. The suspension polymerization of the resulting mixture is effected in an aqueous medium in the presence of an oil-soluble polymerization initiator under stirring, thus making the inorganic dispersant and black colorant firmly bind on the surface of the polymer particles with ion linkages.
