    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 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. In the method, the resin has a site derived from a (meth)acrylic acid ester having a C2-C10 halogenated alkyl group or alicyclic hydrocarbon group and has a weight-average molecular weight of from 150,000 to 1,000,000. The vinyl-based polymerizable monomer contains 5 to 50 wt % crosslinking monomer.
