Beschreibung
Zusammenfassung:	A non-aqueous pigment ink composition contains at least a pigment, a solvent, and non-aqueous resin dispersion of fine particles having pigment dispersing ability. The non-aqueous resin dispersing fine particles may be obtained from copolymerization of a polymerizable monomer mixture containing, as principal constituents, (meth)acrylic acid alkyl ester monomers, which are soluble in a solvent and which are capable of being insolubilized by undergoing polymerization. The (meth)acrylic acid alkyl ester monomers may contain: (i) at least one kind of monomer having a long chain alkyl group having 12 to 25 carbon atoms, and (ii) at least one kind of monomer having at least one kind of functional group selected from the group consisting of a tertiary amino group, a glycidyl group, a carboxyl group, and a macromonomer having a styrene-derived functional group.
