<P>PROBLEM TO BE SOLVED: To provide active energy ray-curable inkjet ink which suppresses curling of a base material caused by the curing shrinkage of a formed image with the lapse of time and suppresses an ejection failure caused by clogging of the nozzle in an inkjet recording head by incorporating a specified ultraviolet absorber into the active energy ray-curable inkjet ink hardly influenced by polymerization inhibition caused by oxygen and humidity and cured with high sensitivity even in small droplets, and an image forming method using the same. <P>SOLUTION: The active energy ray-curable inkjet ink contains: two or more kinds of polymerizable monomers having a polymerizable unsaturated bond; and an ultraviolet absorber. The polymerizable monomers contain at least one kind of electron donating monomer and at least one kind of electron accepting monomer. Also, the ultraviolet absorber includes at least one kind selected from a benzophenone compound, salicylic acid ester compound, a cyanoacrylate compound, a benzotriazole compound and a triazine compound. <P>COPYRIGHT: (C)2013,JPO&INPIT |
