PURPOSE:To provide a photocurable composition which can be cured with low energy of visible light of long wavelengths or near-infrared rays. CONSTITUTION:The composition essentially consists of a compound containing a radical-polymerizable unsaturation, a metal arene compound, a squarylium color and N,N-dialkylaniline. When irradiated with visible light of long wavelength or near-infrared rays, this composition can generate free radicals and can be polymerized. |
