ABSTRACT:
Particles for display media are constructed as spherical resin fine particles, in which functional groups indicating positively-charging properties are existent on their surfaces, which are obtained by polymerizing monomer by utilizing initiator having functional groups indicating positively-charging properties produced by reacting organic alkyl sulfonates and both terminal ends of azo initiator having cationic functional group including nitrogen-containing heterocycle or nitrogen-containing fatty series, or, are constructed as spherical resin fine particles, in which functional group indicating charging properties or ionic properties are existent on their surfaces, which are obtained by polymerizing monomer by utilizing initiator having functional groups indicating charging properties or ionic properties at its both terminal ends.
