[PROBLEMS] The present invention provides a spherical composite material comprising a resin comprising unsaturated vinyl units and a magnetic material; a spherical composite composition, which is produced by a simple production process having high productivity without the need of two or more production steps; and a process of producing the spherical composite composition. [MEANS FOR SOLVING PROBLEMS] The invention provides a spherical composite composition obtained by adding a magnetic material to an aqueous medium having a resin dispersed therein, dispersing the material in the medium, and then forming the dispersion into particles by spray drying, and a process of producing the spherical composite composition. |
