摘要： Disclosed are non-spherical resin particles that allow for improvement of light diffusion, light reflection, and other related properties, and a manufacturing method thereof. The particles have a circular outline when viewed from a direction in which a maximum projected area is produced and a non-circular outline when viewed from a direction in which a minimum projected area is produced, The particles comprise first and second, different resin components (1) and (2), with the second resin component (2) residing locally near the surface of the non-spherical resin particles. The method of manufacturing non-spherical resin particles involves either allowing particles of a resin to absorb a vinyl-based polymerizable monomer contained in an aqueous emulsion followed by polymerization of the absorbed monomer or dissolving a resin in a vinyl-based polymerizable monomer followed by polymerization of the obtained solution in an aqueous medium.
