Photo-curable resin composition

摘要

A novel photo-curable resin composition. The resin composition capable of providing a three-dimensional object having excellent mechanical strength and high dimensional accuracy. The resin composition capable of providing a three-dimensional object with excellent stability in shape and properties in a short time using an photo-fabrication process. The composition comprises, (A) a compound having a cyclohexene oxide structure, (B) a compound having a glycidyl ether structure, (C) an onium salt represented by the following formula (1), (D) an ethylenically unsaturated monomer, (E) a radical photo-initiator, and (F)a polyol having three or more hydroxyl groups in one molecule. wherein Aro represents an aromatic group with a valence of 1-4, X represents a bisphenylsulfonio group which may contain a specific substitutional group, and Z represents a specific halide, a is an integer from 1-4, b is 0 or an integer from 1-3, the sum of a and b is an integer from 1-4, and n is an integer from 1-4.
