Abstract

A curable resin composition for producing a three-dimensional object formed of a cured resin product comprises a polyfunctional urethane (meth)acrylate having a weight-average molecular weight of 1,000 or more and 60,000 or less; a monofunctional radically polymerizable compound having one radically polymerizable functional group in a molecule; a polyfunctional radically polymerizable compound other than the polyfunctional urethane (meth)acrylate; rubber particles; and a radical polymerization initiator. The monofunctional radically polymerizable compound includes a monofunctional acrylamide-based compound, and the content of the polyfunctional radically polymerizable compound other than polyfunctional urethane (meth)acrylate (particularly one having a radically polymerizable functional group equivalent of less than 300 g/eq) is controlled.
