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.

Claim 1
Independent Claim 49 words
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.
Claim 2
Dependent Claim 49 words
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.
Claim 3
Dependent Claim 12 words
The composition according to claim 1, which comprises further a polymeric material.
Claim 4
Dependent Claim 24 words
The composition according to claim 1, wherein the amine in the photopolymerization initiation system is totally replaced by the acryloyl or methacryloyl group-containing amine.
Claim 5
Dependent Claim 24 words
