Abstract
An ink composition has a high storage stability such that decomposition of the components contained in the ink composition can be minimized. This ink composition, which is discharged by using the inkjet method, contains a luminescent pigment, and the amount of hydrogen generated per 100 g of the ink composition measured in a room temperature and normal pressure environment is 1 mL or less. The ink composition may be an active energy ray-curable ink composition or a non-aqueous ink composition containing an organic solvent.
