Abstract
Disclosed is a photocurable ink composition for use in an ink jet recording method wherein an ink composition is brought into contact with a recording medium followed by a photocuring reaction to perform printing. The photocurable ink composition can offer good coating strength, chemical resistance, dispersion stability, and printing stability. This photocurable ink composition comprises at least a colorant, a urethane oligomer, a monomer having a tri- or higher functional reactive group, a photopolymerization initiator, and an aqueous solvent. After printing the photocurable ink composition, ultraviolet light is applied to cure the print. The colorant is preferably anatase titanium dioxide.
