Abstract
An ink composition for printing on metal including a coloring pigment, resins, and a solvent is employed, wherein the ink composition contains a rosin-modified resin having an acid value of 10 to 400 mg KOH/g as at least part of the resins, and the solvent contains at least one compound selected from the group consisting of compounds represented by general formula (1): wherein each A is independently an alkylene group having 2 to 4 carbon atoms that may have a branch structure, R is an alkyl group having 1 to 13 carbon atoms that may have a branch structure and/or a ring structure, and n is an integer of 2 to 6.
