Abstract

Disclosed is an unregularly shaped particle which can provide a molded article for an optical material and having a good balance between light permeability and light-diffusing property, which comprises a particle (X) comprising a first polymer and a particle (Z) comprising a second polymer and arranged at least a part of the surface of the particle (X), and which has a number average particle diameter of 0.3 to 8 μm. Also disclosed is an unregularly shaped particle which can provide a molded article for an optical material and having reduced specularly reflected light on the surface, excellent light-diffusing property and excellent ballistic light transmissivity, which comprises a hollow particle (Y) comprising a third polymer and a particle (Z) comprising a forth polymer and arranged at least a part of the surface of the hollow particle (Y), and which has a number average particle diameter of 0.4 to 10 μm.
