    摘要： An oil-based inkjet ink set is disclosed that includes: an oil-based inkjet ink A containing a non-aqueous solvent, the non-aqueous solvent of the oil-based inkjet ink A containing at least 15% by mass of a silicone oil relative to the total mass of the non-aqueous solvent of the oil-based inkjet ink A, and an oil-based inkjet ink B containing a non-aqueous solvent, the non-aqueous solvent of the oil-based inkjet ink B containing at least 50% by mass of a petroleum-based hydrocarbon solvent relative to the total mass of the non-aqueous solvent of the oil-based inkjet ink B. A method for producing a printed item is also disclosed.

    摘要： An oil-based inkjet ink can be provided which exhibits excellent discharge stability even after a long idle period, and also yields high image density and prevents show-through in printed items. The oil-based inkjet ink contains a pigment, an amide-based dispersant and a non-aqueous solvent, wherein the non-aqueous solvent contains a modified silicone oil having 2 or 3 silicon atoms in one molecule, and a petroleum-based hydrocarbon solvent.

    摘要： An oil-based inkjet ink can be provided which prevents dye conversion of a dye lake pigment contained in the ink, prevents adhesion of the ink to the nozzle plate, and yields excellent drying properties for printed items. The oil-based inkjet ink contains a dye lake pigment, a pigment dispersant and a non-aqueous solvent, wherein the non-aqueous solvent contains a silicone oil having a surface tension of at least 20 mN/m but not more than 28 mN/m. The surface tension of the silicone oil is preferably at least 22 mN/m but not more than 26 mN/m.
