In the optical three-dimensional modeling by the layered modeling method, the modeling apparatus can be easily washed with water, the modeled object can be easily detached from the support, and can be easily cured by irradiation with light of 400 nm or more, The object is to provide a highly versatile polymerizable composition. A water-soluble radically polymerizable compound (A) represented by the formula (1), a photopolymerization initiator (B) that generates radicals upon irradiation with light having a wavelength of 400 nm or more, and an ionic surfactant (C ) Containing a photopolymerizable composition for stereolithography. In Formula (1), R 1 is an a-valent organic group, and a is an integer of 2 or more. R 2 is hydrogen or alkyl having 1 to 6 carbons. |
