Abstract

Official abstract text for this publication.

A colored resin particle dispersion having improved fixation to the printed item immediately after printing and improved color development properties for the printed item, and an inkjet ink containing the colored resin particle dispersion. The colored resin particle dispersion contains colored resin particles, a basic dispersant, and a non-aqueous solvent, wherein the colored resin particles contain a colorant and a (meth)acrylic-based resin, and the (meth)acrylic-based resin has a unit A having a carboxyl group, a unit B having a phosphoric acid group and/or a phosphate ester group, and a unit C having an aromatic ring.

First claim

Opening claim text (preview).

What is claimed is: 1. A colored resin particle dispersion comprising colored resin particles, a basic dispersant, and a non-aqueous solvent, wherein the colored resin particles comprise a colorant and a (meth)acrylic-based resin, and the (meth)acrylic-based resin has: a unit A having a carboxyl group, a unit B having a phosphoric acid group and/or a phosphate ester group, and a unit C having an aromatic ring. 2. The colored resin particle dispersion according to claim 1 , wherein the colored resin particles further comprise a liquid organic compound having an acidic group. 3. The colored resin particle dispersion according to claim 1 , wherein the (meth)acrylic-based resin has a weight-average molecular weight within a range from 5,000 to 100,000 and an acid value within a range from 30 to 300 mgKOH/g. 4. The colored resin particle dispersion according to claim 1 , wherein relative to all the units that constitute the (meth)acrylic-based resin, the unit A having a carboxyl group represents 5 to 45% by mass, the unit B having a phosphoric acid group and/or a phosphate ester group represents 1 to 10% by mass, and unit C having an aromatic ring represents 5 to 50% by mass. 5. The colored resin particle dispersion according to claim 1 , wherein the (meth)acrylic-based resin further comprises a unit D having an alkoxysilyl group. 6. The colored resin particle dispersion according to claim 5 , wherein the (meth)acrylic-based resin further comprises a unit D having an alkoxysilyl group in an amount of 0.1 to 10% by mass relative to all the units that constitute the (meth)acrylic-based resin. 7. An inkjet ink comprising the colored resin particle dispersion according to claim 1 .
