(57) Abstract: An energy ray-curable epoxy resin composition, a resin composition for optical three-dimensional modeling, and an optical three-dimensional modeling method that provide a cured product having excellent physical properties and excellent dimensional stability due to moisture absorption. I will provide a. SOLUTION: As essential constituent components, (1) a specific cationically polymerizable organic substance, (2) an energy ray-sensitive cationic polymerization initiator, and, if necessary, (3) the above specific cationically polymerizable organic substance Ray curable epoxy resin composition containing a cationic polymerizable organic substance other than the above, (4) a radical polymerizable organic compound, and (5) an energy ray sensitive radical polymerization initiator, and optical three-dimensional molding using the same. Resin composition for use and an optical three-dimensional molding method. |
