ABSTRACT:
To provide an active energy ray curable aqueous ink composition exhibiting excellent curing performance by including a water-soluble polymerizable substance with high reactivity and a water-soluble polymerization initiator having high initiation efficiency; and an inkjet recording method, ink cartridge, recording unit, and inkjet recording apparatus all using the active energy ray curable aqueous ink composition. The active energy ray curable aqueous ink composition includes at least water; a polymerizable substance which undergoes radical polymerization by active energy rays; and a polymerization initiator which generates radicals by active energy rays, in which the polymerizable substance is a water-soluble compound having 2 to 6 (meth)acrylic groups; and the polymerization initiator is a water-soluble acylphosphine oxide compound.
