Patent ID: 8067143

Claim:
A method of manufacturing a functional particle comprising a step of flowing a mixed slurry containing a core particle as a resin particle and a shell particle of a resin particle having a volume average particle size less than that of the core particle through a coiled pipeline while heating the mixed slurry to a glass transition temperature or higher of the core particle, thereby obtaining a functional particle in which the shell particle is deposited on a surface of the core particle, wherein the heating temperature A of the mixed slurry containing the core particles and the shell particles in the coiled pipeline satisfies the following relation: Tg ( c )< A<Tg ( s )< Mp ( c ) (1) where Tg(c) represents a glass transition temperature of a core particle, Tg(s) shows a glass transition temperature of a shell particle, and Mp(c) represents the melting point of the core particle).
