METHOD FOR PRODUCING CORE-SHELL FINE PARTICLE AND METHOD FOR PRODUCING INTERMEDIATE WHICH IS USED FOR PRODUCTION OF THE CORE-SHELL FINE PARTICLE

摘要

A core-shell fine particle (10) is produced as follows. First of all, a monomer mixture containing 15-99% by mass of a crosslinkable monomer and 1-85% by mass of a monomer having an ATRP initiating group is adsorbed into an organic monodispersed seed particle. Next, the monomer mixture is polymerized by a polymerization initiator, thereby forming a core layer composed of a monodispersed crosslinked fine particle (11) containing an ATRP initiating group (12). A shell layer (13) is then formed by graft-polymerizing a monomer onto the thus-obtained core layer.
