PHOTOCURABLE RESIN COMPOSION

摘要

PURPOSE: A photocurable resin composition is to provide a three dimensional object having excellent mechanical strength, high dimensional accuracy and a three dimensional object with excellent stability in shape using an optical fabricating process. CONSTITUTION: The photocurable resin composition comprises (A) a cationic polymerized compound, (B)a cationic photoinitiator, (c) an ethylenically unsaturated monomer, (D) a radical photoinitiator, (E) a polyether polyol having on the ethylenically unsaturated monomer having three or more ethylenically unsaturated bonds in one molecule.
