Abstract

Official abstract text for this publication.

A non-aqueous magenta ink composition for ink jet printing comprising a pigment, a pigment dispersant, a binder resin and an organic solvent, wherein the pigment comprises C.I. Pigment Red 254 and a red pigment having a quinacridone skeleton, and wherein a total amount of the C.I. Pigment Red 254 and the red pigment having a quinacridone skeleton is not less than 50% by mass in the pigment.

First claim

Opening claim text (preview).

The invention claimed is: 1. A non-aqueous magenta ink composition for ink jet printing comprising a pigment, a pigment dispersant, a binder resin and an organic solvent, wherein the pigment comprises C.I. Pigment Red 254 and a red pigment having a quinacridone skeleton, wherein a total amount of the C.I. Pigment Red 254 and the red pigment having a quinacridone skeleton is not less than 50% by mass in the pigment, wherein the compounding ratio of the C.I. Pigment Red 254 to the red pigment having a quinacridone skeleton is 4:6 to 6:4, and wherein the organic solvent comprises alkylene glycol dialkyl ether. 2. The non-aqueous magenta ink composition for ink jet printing of claim 1 , wherein the pigment having a quinacridone skeleton is at least one selected from C.I. Pigment Violet 19, C.I. Pigment Red 122 and C.I. Pigment Red 202. 3. The non-aqueous magenta ink composition for ink jet printing of claim 1 , wherein the pigment having a quinacridone skeleton is C.I. Pigment Red 122. 4. The non-aqueous magenta ink composition for ink jet printing of claim 1 , wherein the binder resin comprises at least either of a vinyl polymer and an acrylic resin, and the vinyl polymer comprises at least one selected from the group consisting of a vinyl chloride polymer, a vinyl chloride-vinyl acetate copolymer and an ethylene-vinyl acetate copolymer. 5. The non-aqueous magenta ink composition for ink jet printing of claim 1 , comprising the organic solvent comprising at least one selected from the group consisting of a cyclic ester compound, (poly)propylene glycol monoalkyl ether and (poly)propylene glycol monoalkyl ether monoalkyl ester in a total amount of 1 to 30% by mass in the non-aqueous magenta ink composition.
