Provided are a photocurable resin composition and an optical three-dimensional modeling method capable of producing a three-dimensional modeled article that is excellent in handleability during optical modeling and excellent in mechanical properties. A photocurable resin composition comprising a urethanized acrylic compound (I) represented by the following general formula (I), a monofunctional acrylate, another (meth) acrylate compound, and a radical photopolymerization initiator. {In the formula, R 1 is H or a methyl group, d is 1 or 2, and when d is 2, one or both R 1 is a methyl group, A is a diol or triol residue, D is divalent or trivalent An unsubstituted or substituted hydrocarbon group, G is a group represented by the formula:-(CH 2 CH 2 O) g- (wherein g is 1 to 4), a formula:-[(CH 2 CH (CH 3) O] h- (group or the formula :-( CH 2 CH 2 O) j [(CH 2 CH (CH 3 h in the formula represented by 1~4)) O] k- (and wherein j k is 1 to 3 and the sum of j and k is 2 to 4), R 2 is H or an alkyl group, e is 1 or 2, and f is 3 or 4} [Selection figure] None |
