According to the present, invention, a process for producing an epoxy compound, where an epoxy compound can be selectively produced from olefins with good yield at low cost in a safe manner by a simple operation under mild conditions without using a quaternary ammonium salt or a metal compound, is provided. The present invention relates to a process for producing an epoxy compound, comprising epoxidizing a carbon-carbon double bond of an organic compound having a carbon-carbon double bond by using hydrogen peroxide as an oxidant, wherein the epoxidation is carried by out using an organic nitrile compound and an organic amine compound.

The purpose of the present invention is to provide a resin composition which is capable of producing a three-dimensional object having high tensile strength and dimensional accuracy and is easily detectable by a metal detector. The resin composition is used in a method in which a liquid-liquid type resin composition is selectively irradiated with an active energy ray to produce a three-dimensional object composed of a cured product of the resin composition. The resin composition contains a photopolymerizable compound and a metal-containing particle, which can be detected by a metal detector and has been surface-treated with a surfactant, the content of the metal-containing particle being 10-55 mass% with respect to the solid content of a resin.
