摘要

A nonaqueous ink-jet ink which is excellent in suitability for printing on polyvinyl chloride, delivery stability, and safety, is extremely reduced in odor emission, and can be stably used over long without causing a trouble in the ink-jet head(s). The nonaqueous ink-jet ink is characterized by comprising the solvent (A) shown below, the solvent (B) shown below, a pigment, and a polymer, the contents of the solvent (A) and the solvent (B) being 3-15 mass% and 50-90 mass%, respectively. Solvent (A): 1,3-dimethyl-2-imidazolidinone Solvent (B): solvent comprising one or more compounds selected from compounds represented by the following general formulae (1) and (2).
