<p>PROBLEM TO BE SOLVED: To obtain a photocurable composition for optical three-dimensional molding, which can be easily cured by irradiation with a ray at a wavelength of 400 nm or more and which gives a molded article that can be easily detached from a container.SOLUTION: The photocurable composition for optical three-dimensional molding comprises: a radical polymerizable compound (A); a photopolymerization initiator (B) that generates a radical by irradiation with a ray at a wavelength of 400 nm or more; and a water-insoluble surfactant (C). A cured film having a film thickness of 30μm obtained by irradiating the above photocurable composition with a ray at a wavelength of 400 nm or more has an elastic modulus of 10 to 500 MPa by a tension test; the cured film has a breaking strength of 1 to 50 MPa; and the cured film has a breaking elongation of 10 to 100%.</p> |
