Abstract
Official abstract text for this publication.
A non-aqueous pigment ink includes a pigment, a non-aqueous solvent, a non-water-soluble resin and a water-soluble resin, wherein the non-water-soluble resin is an acrylic polymer formed by a copolymer of a monomer mixture containing at least an alkyl (meth)acrylate (A) having a C8 to C18 alkyl group and a monomer (B) having a β-diketone group or β-keto acid ester group.
First claim
Opening claim text (preview).
What is claimed is: 1 . A non-aqueous pigment ink comprising: a pigment; a non-aqueous solvent; a non-water-soluble resin; and a water-soluble resin; wherein the non-water-soluble resin is an acrylic polymer formed by a copolymer of a monomer mixture containing at least an alkyl (meth)acrylate (A) having a C 8 to C 18 alkyl group and a monomer (B) having a β-diketone group or β-keto acid ester group; and the acrylic polymer does not include a urethane group. 2 . The non-aqueous pigment ink as claimed in claim 1 , wherein the water-soluble resin is a polyethylene imine having a mass average molecular weight of from 200 to 2000. 3 . The non-aqueous pigment ink as claimed in claim 1 , wherein a content of the water-soluble resin is from 0.01 to 0.5 in mass ratio relative to the pigment. 4 . The non-aqueous pigment ink as claimed in claim 1 , wherein a content of the acrylic polymer is from 0.1 to 1.0 in mass ratio relative to the pigment. 5 . The non-aqueous pigment ink as claimed in claim 1 , wherein a content of the acrylic polymer is from 0.1 to 20 in mass ratio relative to the water-soluble resin. 6 . The non-aqueous pigment ink as claimed in claim 1 , wherein the monomer (B) has a β-diketone group. 7 . The non-aqueous pigment ink as claimed in claim 6 , wherein the β-diketone group is an acetoacetyl group or a propion acetyl group. 8 . The non-aqueous pigment ink as claimed in claim 1 , wherein the monomer (B) has a β-keto acid ester group. 9 . The non-aqueous pigment ink as claimed in claim 8 , wherein the β-keto acid ester group is an acetoacetoxy group or a propion acetoxy group. 10 . The non-aqueous pigment ink as claimed in claim 1 , wherein the content of the alkyl (meth)acrylate (A) having a C 8 to C 18 alkyl group in the monomer mixture is 30 mass % or more. 11 . The non-aqueous pigment ink as claimed in claim 1 , wherein the content of the monomer (B) having a β-diketone group or β-keto acid ester group in the monomer mixture is from 3 mass % to 30 mass %. 12 . The non-aqueous pigment ink as claimed in claim 1 , wherein the content of the alkyl (meth)acrylate (A) having a C 8 to C 18 alkyl group in the monomer mixture is from 50 mass % to 90 mass %, and the content of the monomer (B) having a β-diketone group or β-keto acid ester group in the monomer mixture is from 5 mass % to 20 mass %.
