Abstract
A liquid container may be connected to a liquid consuming unit. The liquid container includes an ink holder containing an ink composition, and an ink delivering portion through which the ink composition flows out of the ink holder. The ink composition contains an aqueous medium and a water-resistant metal pigment that includes pigment particles whose surfaces are covered with a coating and reacts with the aqueous medium to generate hydrogen gas. The amount of hydrogen gas generated per day from the ink composition in the ink holder is lower than or equal to the amount of hydrogen gas permeating per day through the ink holder, in an environment of 25° C.
