Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of a three-dimensional shaped article constituted of a titanium oxide-containing composition which reduces the lowering of a curing depth caused by the light scattering of a titanium oxide and the obstruction cause of photopolymerization reaction caused by light activity, shows favorable following performance and photosetting properties even if the content of the titanium oxide is increased and can be easily shaped into a desired three-dimensional shaped article by an optical laminate shaping method. SOLUTION: A photosetting liquid composition which contains titanium oxide particles (A) of which the number average particle size by an electron microscopic method is 10-500 nm, a compound (B) having a polymerizable functional group and a photopolymerization initiator (C) is irradiated with light to form the cured layer of the composition and the composition is again supplied to the surface of the cured layer and irradiated with light to further form the cured layer of the composition. By repeating this process, the three-dimensional shaped article having the cured layer integrally laminated thereto is shaped. COPYRIGHT: (C)2008,JPO&INPIT
