Abstract
A photo-curable resin composition for three-dimensional shaping includes a polyfunctional radical polymerizable compound (A), a monofunctional radical polymerizable compound (B), polyethylene particles (C), and a curing agent (D). The polyfunctional radical polymerizable compound (A) is a single polyfunctional radical polymerizable compound having an ethylenically unsaturated group equivalent of 700 g/eq or more and 8,000 g/eq or less or a mixture including a plurality of types of polyfunctional radical polymerizable compounds and having an ethylenically unsaturated group equivalent of 700 g/eq or more and 8,000 g/eq or less, the ethylenically unsaturated group equivalent being a weighted average of ethylenically unsaturated group equivalents of the polyfunctional radical polymerizable compounds in terms of weight ratio. A content of the polyethylene particles (C) is 5 parts by mass or more and 50 parts by mass or less relative to 100 parts by mass of a total of the polyfunctional radical polymerizable compound (A) and the monofunctional radical polymerizable compound (B).
