(57) [Summary] [Structure] An ink composition containing a near-infrared absorber and an acrylic resin, a hydrocarbon resin, or a copolymer resin of an acrylic compound and a hydrocarbon compound. [Effect] The ink composition of the present invention exhibits high light resistance, and a printed matter produced using the ink composition has a remarkable difference in reflectance between a recorded portion and a non-recorded portion in a specific near-infrared region, which causes a reading error. Unlikely to occur. |
