    • A non-aqueous pigment ink comprising a pigment, a non-aqueous solvent, and non-aqueous resin dispersion microparticles having a pigment dispersion capability, wherein the non-aqueous resin dispersion microparticles are an acrylic polymer comprising an alkyl (meth)acrylate unit having an alkyl group of 12 or more carbon atoms and a (meth)acrylate unit having a urethane group. The acrylic polymer is a copolymer of a monomer mixture comprising an alkyl (meth)acrylate (A) having an alkyl group of 12 or more carbon atoms and a reactive (meth)acrylate (B) having a functional group capable of reacting with an amino group, wherein the urethane group is introduced by a reaction between the functional group capable of reacting with an amino group, an amino alcohol and a polyvalent isocyanate compound, and the mass ratio within the acrylic polymer between the copolymer portion and the introduced urethane group portions is within a range from 60:40 to 99:1.
