| 摘要 |
This photopolymerization method photopolymerizes, under acidic conditions, an ink composition containing (A) a polymerizable compound, (B) a photopolymerization initiator, and (C) a hydrogen donor. This photopolymerization method photopolymerizes, under acidic conditions, an ink composition containing (A) a polymerizable compound having an ethylenic unsaturated group, (B) a photopolymerization initiator represented by general formula (1), and (C) a hydrogen donor having a structure in which a nitrogen atom is linked directly to an aromatic ring, the hydrogen donor being such that the aromatic ring has an electron-withdrawing group or such that the nitrogen atom is a constituent of a hetero ring. In general formula (1), R1-R30 represent hydrogen atoms, halogen atoms, alkyl groups, or alkoxy groups. |
