Abstract
A non-aqueous pigment ink which suppresses show-through and improves the print density in printed items, and also exhibits excellent storage stability. The non-aqueous pigment ink comprises a pigment, a non-aqueous solvent, and non-aqueous resin dispersion particles having a pigment dispersion capability, wherein the non-aqueous resin dispersion particles comprise a urethane-modified alkyd resin formed from an oil-modified alkyd resin and/or fatty acid-modified alkyd resin having an oil length of not less than 50% by mass into which urethane groups have been introduced, and the urethane-modified alkyd resin is prepared by bonding an amino alcohol to double bonds within the oil-modified alkyd resin and/or fatty acid-modified alkyd resin, and then reacting the amino alcohol with a polyvalent isocyanate compound to introduce the urethane groups.
