PURPOSE:To provide an optical stereoscopic shaping resin composition and an optical stereoscopic shaping method using the composition, the deformation after the shaping of which is small and the mechanical characteristics of which are excellent. CONSTITUTION:An optical stereoscopic shaping resin composition contains an energy rays curable cationic polymerizable organic substance (1), a silicone resin (2), which contains both an energy rays curable cationic polymerizable group and a group improving the solubility of the substance (1), and an energy rays sensitive cationic polymerization initiator (3). Since the resin composition mainly made of the energy rays curable cationic organic substance is employed, the optical stereoscopic shaping method neither being effected by oxygen in the air nor being required by a postcuring treatment, which is indispensable for a resin composition mainly made of an energy rays curable radical polymerization resin. Accordingly, the deformation of the cured matter due to the postcuring treatment can be improved. |
