Abstract
(EN)
Provided is a composition for optical three-dimensional shaping which can be optically shaped (photocured) within a shorter period of time and gives a three-dimensionally shaped article having excellent strength (for example, durability against fracture, etc. upon impact or dropping and durability against repeated folding). The composition for optical three-dimensional shaping according to the present invention at least comprises: (A) as radical-polymerizable compounds, (A1) 2-40 mass% of a dioxane (meth)acrylate radical-polymerizable compound, (A2) 5-40 mass% of a bifunctional polyester type urethane (meth)acrylate radical-polymerizable compound, (A3) 5-40 mass% of a bifunctional polyether type urethane (meth)acrylate radical-polymerizable compound, and (A4) 20-87 weight% of a radical-polymerizable compound other than (A1), (A2) and (A3); (B) 0.1-5 mass% of a photopolymerization initiator; and (C) 0.1-5 mass% of a sensitizer.
