Abstract
Inkjet inks are described herein. In an example, an inkjet ink can comprise: at least one colorant; at least one solvent comprising glycerol in an amount of from about 1 wt % to about 20 wt % based on the total weight of the inkjet ink; water; and at least one binder, wherein the binder comprises a polyurethane-based binder dispersion.
Claims14
An inkjet ink composition comprising:
- a colorant;
- a solvent comprising glycerol in an amount of from about 1 wt % to about 20 wt % based on the total weight of the inkjet ink composition;
- water;
- and
- a binder comprising a polyurethane-based binder dispersion including water and a polyurethane, the polyurethane comprising:
- (A) polyisocyanate,
- (B) a first polyol having a chain with two hydroxyl functional groups at one end of the chain and no hydroxyl groups at an opposed end of the chain,
- (C) a second polyol having a chain with two hydroxyl functional groups at both ends of the chain,
- (D) a carboxylic acid functional group that further includes two hydroxyl functional groups, and
- (E) a sulfonate or sulfonic acid functional group that further includes two amino functional groups.

Art ink set comprising:
- (i) a black ink comprising:
- water,
- a solvent comprising glycerol in an amount of from about 3 wt % to about 12 wt % based on the total weight of the inkjet ink composition;
- a black pigment in a polymeric dispersion, wherein the polymeric dispersion comprises a styrene acrylic polymer, and
- a binder, wherein the binder comprises a polyurethane-based binder dispersion, which comprises water and a polyurethane, wherein the polyurethane comprises:
- (A) a polyisocyanate,

- (C) a second polyol having a chain with two hydroxyl functional groups at both ends of the chain,
- (D) a carboxylic acid functional group that further includes two hydroxyl functional groups, and
- (E) a sulfonate or sulfonic acid functional group that further includes two amino functional groups;
- and
- (ii) a cyan ink comprising:
- water,
- a solvent comprising glycerol in an amount of from about 3 wt % to about 12 wt % based on the total weight of the inkjet ink composition;
- a cyan pigment in a polymeric dispersion, wherein the polymeric dispersion comprises a styrene acrylic polymer, and
- a binder, wherein the binder comprises a polyurethane-based binder dispersion, which comprises water and a polyurethane, wherein the polyurethane comprises:
- (A) a polyisocyanate,
- (B) a first polyol having a chain with two hydroxyl functional groups at one end of the chain and no hydroxyl groups at an opposed end of the chain,
- (C) a second polyol having a chain with two hydroxyl functional groups at both ends of the chain,
- (D) a carboxylic acid functional group further includes two hydroxyl functional groups, and
- (E) a sulfonate or sulfonic acid functional group that further includes two amino functional groups.
