摘要:
Organosilicone fine particles which are capable of responding to the highly advanced requirements of recent years imposed on them for purposes of actual use, including further improvement in optical characteristics such as total light transmittance and haze as well as heat-resistant colorability related to resin compositions, further improvement in usability (extensions and expansions at the time of use) and feeling (stickiness, roughness and durability) related to cosmetic materials and further improvement in matte effect and factual sense related to paint compositions, as well as methods of their production and cosmetic materials, resin compositions and paint compositions containing such particles are provided. Organosilicone fine particles have tetrahedral general shapes with surfaces each having a concave part with an approximately circular opening. The maximum external diameters L of the organosilicone fine particles have an average value in the range of 0.5-20 μm, the average value being taken from arbitrarily selected 20 of a scanning electron microscope photograph image of the organosilicone fine particles.
