Abstract
An object of the invention is to provide a yellow ink composition for nonaqueous inkjet that achieves excellent density and weather resistance on printed matters whose printing surface is constituted by a polyvinyl chloride polymer, ethylene-vinyl acetate copolymer, or other vinyl polymer or the like, while also ensuring excellent discharge stability, even in a high-speed printing mode. To this end, a yellow ink composition for nonaqueous inkjet is provided that contains, as the pigment, C. I. Pigment Yellow 150 and C. I. Pigment Yellow 83 at a ratio by mass, calculated by 'C. I. Pigment Yellow 150/C. I. Pigment Yellow 83,' of 5/5 to 9/1, and further contains a pigment dispersant, a resin, and an organic solvent.
