PROBLEM TO BE SOLVED: To provide a novel titanium oxide particle excellent in light scattering performance against light ranging from visible light to near-infrared light. SOLUTION: A hydrolysate of titanium alkoxide or a hydrolysate of a titanium metal salt is mixed with organic alkalis in a prescribed solvent to prepare a reaction solution. The reaction solution is subsequently heated in a sealed vessel to produce the titanium oxide particle which has radially extended parts, each having a ridge in almost the middle of its length, and forms a star shape as a whole. The star-shaped titanium oxide particle can be contained in a paint, a resin composition, a plastic film, a plastic sheet, etc. to improve their whiteness. COPYRIGHT: (C)2006,JPO&NCIPI
