<P>PROBLEM TO BE SOLVED: To provide an active-ray curable ink composition which can form a cured film excellent in flexibility without damaging photopolymerizability even under high humidity and an inkjet recording method. <P>SOLUTION: The active ray curable ink composition includes a photoacid generator, a polymerizable monomer, and an urethane compound, and not less than 50 mass% of the polymerizable monomer is a vinyl ether compound, and the urethane compound has at least one vinyl ether group, methacryloyl group or acryloyl group as a polymerizable group, and the active ray curable composition has a viscosity at 25°C of 7-100 mPa s and a water content of 0.5 mass% or less. <P>COPYRIGHT: (C)2011,JPO&INPIT |
