Abstract
A water-based pigment type inkjet ink composition contains: a pigment whose surface is formed as a resin layer produced by crosslinking, using a crosslinking agent having two or more functionalities, an alkali-soluble resin whose acid value is 40 to 300 KOHmg/g, and 50 to 90% of whose acid groups have been neutralized by a basic compound; a water-soluble organic solvent; and a surface-active agent; wherein the alkali-soluble resin is such that lauryl(meth)acrylate is contained in the alkali-soluble resin, as its constitutional unit monomer, by 20 to 40 percent by mass relative to the total quantity of monomers. The water-based pigment type inkjet ink composition can exhibit good printability characteristics as well as a wide color gamut and can also offer excellent storage stability.
