There are provided inorganic/polymer composite particles having good UV-scattering efficiency and improved dispersion stability in organic formulation; and a method for preparing the same, which comprises the following steps of (1) dispersing hydrophobic-treated inorganic particles in monomer and then adding initiator thereto; (2) emulsifying the inorganic dispersion of step (1) in presence of surfactant and dispersion stabilizer; and (3) suspension polymerizing the inorganic/monomer emulsion of step (2), to give inorganic/polymer composite particles.
