Curable resin composition and cured product thereof

A method for producing a three-dimensional object, comprising repeating a step of supplying an uncured layer formed of a curable resin composition and a step of irradiating the uncured layer with an active energy lay based on three-dimensional shape data on a three-dimensional model, to thereby obtain a shaped object formed of a cured product of the curable resin composition,

• wherein the curable resin composition 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,
• wherein the monofunctional radically polymerizable compound includes a monofunctional acrylamide-based compound, and
• wherein the polyfunctional radically polymerizable compound other than the polyfunctional urethane (meth)acrylate has a radically polymerizable functional group equivalent of not less than 300 g/eq, or a content of the polyfunctional radically polymerizable compound other than the polyfunctional urethane (meth)acrylate with respect to 100 parts by mass in total of the monofunctional radically polymerizable compound and the polyfunctional radically polymerizable compound other than the polyfunctional urethane (meth)acrylate is more than 0 parts by mass and less than 20 parts by mass.
