PROBLEM TO BE SOLVED: To provide a composition which is (i) quickly cured by the irradiation with light energy and gives a three-dimensional molded product with (ii)good mechanical properties (tensile strength, elongation, tensile modulus, and heat resistance) and (iii) a high transparency. SOLUTION: The composition for three-dimensional molding contains urethane (meth)acrylate (A) yielded by reacting a compound (a1) represented by general formula (I) with an organic diisocyanate compound (a2). In general formula (I), X<SP>1</SP>and X<SP>2</SP>are each H or an acryloyl, methacryloyl, hydroxy, or alkyl group, provided at least either of them is an acryloyl or methacryloyl group; and R<SP>1</SP>, R<SP>2</SP>, and R<SP>3</SP>are each an oxyalkylene or polyoxyalkylene group.
