摘要
A non-aqueous ink-jet ink which has printability on non-absorbing recording media such as polyvinyl chloride (abrasion resistance and water resistance), is excellent in ejection stability and safety, is free from problems concerning odor, does not cause operational abnormality in an ink-jet head even in long-term use, and can be stably used even after long-term storage. Also provided is a method of ink-jet recording with the ink. This non-aqueous ink-jet ink comprises a pigment, a binder resin, and an organic solvent. It is characterized in that at least 60 mass% of the organic solvent is accounted for by a water-soluble organic solvent and that the content in the ink of a metal salt which is the highest in content among the salts of metals selected among sodium, potassium, magnesium, and calcium is 3-50 ppm in terms of metal-ion concentration.
