Cationically polymerizable resin composition for three-dimensional photofabrication and method for producing three-dimensional photofabricated product

Abstract

Provided is a cationically polymerizable resin composition for three-dimensional photofabrication that contains a cationically polymerizable monomer (A), a photocationic polymerization initiator (B) containing a photoacid generator (b1), a photosensitizer (b2), and an electron-donating compound (b3) that is at least one type of thiophene compound selected from the group consisting of monothiophene compounds having a π-conjugated substituent as a substituent, dithiophene compounds, and trithiophene compounds, and a basic compound (C). The content of the electron-donating compound (b3) is 0.001-10 parts by mass and the content of the basic compound (C) is 0.0001-5.0 parts by mass per 100 parts by mass of the cationically polymerizable monomer (A). Also provided is a method for producing a three-dimensional photofabricated product using this cationically polymerizable resin composition for three-dimensional photofabrication.
