| abstract |
An ink composition having good stability over time, curing sensitivity, and landing position accuracy of the ink composition is provided. A pigment, water, a water-soluble polymerizable compound, and an oxazinyl group at a terminal and a substituent containing an -OM group, a -COOM group, or a -SO3M group via an oxygen atom or a sulfur atom at the para position. An ink composition containing a compound having a specific structure is used. An ink set in which a polymerizable compound has a (meth) acrylamide structure, and includes these ink compositions and a treatment liquid containing an aggregating agent that aggregates the components in the ink composition.
