Abstract
Organic spherical particles having a cationic group and an average particle size of 0.1-1000 .mu.m, which particles have adsorbed on the surface at least one modifier selected from a compound having an anionic group, fine particles having an anionic group and negatively chargeable fine particles, and also a process for their production, wherein where the particles are composed of an epoxy type resin cured with an amine type curing agent, they can satisfactorily adsorb the aforesaid substance. As a result of the adsorption of the aforesaid substance to the particles, the static build-up properties, electrical conductivity, color shade, and other properties of the particles may be modified, and also it is possible to impart ultraviolet light absorbing ability and to prevent blocking between the particles. These particles may be employed as formulation ingredients for cosmetics, paints, electrostatic copier toners etc.
