Abstract
Abstract A photo-curable composition having a high photosensitivity which comprises a photopolymerizable monomer and, as a photopolymerization initiatiation system, an aromatic ketone and an amine, characterized in that at least a portion of said monomer and/or said amine is an amine having an acryloyl or methacryloyl group in the molecule.
