<p>[Problem] Conventional particles having good redispersibility include dispersion stabilizers such as surfactants, and when these particles are added to various types of molded products or coating materials, problems such as discoloration and degraded physical properties occur. The purpose of the present invention is to overcome these problems by providing an aggregated microparticle having excellent handling properties that can be used in a wide range of applications including inks, coating materials, or resin molded articles, and that readily redisperses to primary particles when added to an organic solvent or kneaded into various types of resin. [Solution] An aggregate resin particle in which an oil-soluble vinyl-based polymer is compounded with a raw-material aggregate particle obtained by aggregation of fine resin particles, the composite aggregate resin particle having an amorphous shape overall, and the fine resin particles contained therein maintaining the pre-aggregation shape thereof.</p> |
