Light-curable resin composition, cured product and three-dimensional shape, and method for manufacturing three-dimensional shape

Abstract

This invention provides a photocurable resin composition capable of forming optical three-dimensional shapes possessing both mechanical properties, impact resistance, and heat resistance; the cured form thereof; the three-dimensional shape thereof; and a method for manufacturing the three-dimensional shape. The photocurable resin composition of this invention comprises the following components a to e: a. a difunctional alicyclic epoxy compound in which two alicyclic epoxy groups are linked by a linking group (L), wherein the linking group (L) has two or more ester groups and an alkyl group having two or more carbon atoms; b. a compound having one or more oxobutane rings in its molecule; c. a polyfunctional (meth)acrylate; d. a cationic photoinitiator; e. a free radical initiator.
