A novel class of layered microparticles comprises a thermoplastic or crosslinked polymeric core containing anionic functional corona groups bonded to the core particle surface, and an oxidatively polymerized shell such as a polypyrrole embedded in the corona. The particles are useful e.g. as conductor material or electrophoretic or colloidal dye; they may be dried and redispersed in polar solvents by conventional means without changing the particles' properties. |
