Title:
CATIONICALLY POLYMERIZABLE RESIN COMPOSITION FOR 3D STEREOLITHOGRAPHY AND METHOD FOR PRODUCING 3D STEREOLITHOGRAPHY PRODUCT
Document Type and Number:
WIPO Patent Application WO/2024/038705
Kind Code:
A1
Abstract:
Provided is a cationically polymerizable resin composition for 3D stereolithography 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, dithiophene compounds, and trithiophene compounds having a π-conjugated substituent as a substituent, and a basic compound (C). The content of the electron-donating compound (b3) is 0.001-10 mass parts and the content of the basic compound (C) is 0.0001-5.0 mass parts per 100 mass parts of the cationically polymerizable monomer (A). Also provided is a method for producing a 3D stereolithography product using this cationically polymerizable resin composition for 3D stereolithography.
