摘要

Core-shell (C-S) particles with a colored shell layer are prepared in an organic solvent system by a coacervation process. As the core-particles, a toner size polyethylene-norbornene copolymer particles are used. A dye molecules dissolved in acetone are precipitated onto the core particles from an acetone/water mixed solvent to form the colored C-S particles. The C-S particles are obtained without surfactant, need no washing process, and show sufficient color strength as well as good color reproduction. The colored shell layer also shows an excellent charge controlling capability, but the dye particles abraded from the colored shell layer function as a charge reducing agent. A resinous protecting layer deposited on the colored shell layer realizes colored particles with excellent durability and charge controlling capability.
