<p><P>PROBLEM TO BE SOLVED: To provide a photo-curable composition for micro-optical shape-forming, which is used for producing a metal-shaped article by using a micro-optical shape-forming process, and can easily produce a shape-formed article having adequate electroconductivity and a fine and highly precise three-dimensional shape that can be used for MEMS or the like. <P>SOLUTION: The photo-curable composition includes (A) a monomer having three or more ethylenic unsaturated groups, (B) a photoinitiator, and (C) metallic microparticles having a number average particle diameter of 0.5 to 3μm when measured with a dynamic light scattering method. The blended ratio of the component (C) is 60 to 95 mass% with respect to 100 mass% of the total mass of the photo-curable composition. Blended ratios of the component (A) and the component (B) is respectively 70 to 95 mass% and 0.01 to 10 mass% with respect to 100 mass% of the total mass of the photo-curable composition except the component (C). The composition 20 is used as a material of a layer 19 to be hardened in the micro-optical forming process, and is formed into a three-dimensional shape-formed article. The metal-shaped article is obtained by sintering the three-dimensional shape-formed article. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
