Abstract
Disclosed herein are aqueous inkjet ink compositions and coating compositions comprising: at least one pigment; at least one polymer; and at least one water-soluble compound having a hydroxyl number of at least 40, wherein the at least one water-soluble compound is selected from ethoxylated C3-C20 polyols, C4-C20 polyols having three or more hydroxyl groups, and polyether polyols, and wherein the at least one water-soluble compound is present in an amount ranging from 1% to by 60% weight, relative to the total weight of the composition, wherein the composition comprises a total amount of water-soluble organic components ranging from 25% to 60% by weight, relative to the total weight of the composition.
Claims24
An aqueous inkjet ink composition comprising:
- at least one pigment;
- at least one polymer;
- and
- at least one water-soluble compound having a hydroxyl number of at least 40, wherein the at least one water-soluble compound is selected from ethoxylated C3-C20 polyols, C4-C20 polyols having three or more hydroxyl groups, and polyether polyols, and wherein the at least one water-soluble compound is present in an amount ranging from 1% to by 60% weight, relative to the total weight of the composition,
- wherein the composition comprises a total amount of water-soluble organic components ranging from 25% to 60% by weight, relative to the total weight of the composition.
A coating composition, comprising:
- at least one pigment;
- at least one polymer;
- and
- at least one water-soluble compound having a hydroxyl number of at least 40, wherein the at least one water-soluble compound is selected from ethoxylated C3-C20 polyols, C4-C20 polyols having three or more hydroxyl groups, and polyether polyols, and wherein the at least one water-soluble compound is present in an amount ranging from 1% to by 60% weight, relative to the total weight of the composition,
- wherein the composition comprises a total amount of water-soluble organic components ranging from 25% to 60% by weight, relative to the total weight of the composition.
A method of inkjet ink printing, comprising:
- depositing onto a coated inkjet paper an aqueous inkjet ink composition comprising:
- at least one pigment;
- at least one polymer;
- and
- at least one water-soluble compound having a hydroxyl number of at least 40, wherein the at least one water-soluble compound is selected from ethoxylated C3-C20 polyols, C4-C20 polyols having three or more hydroxyl groups, and polyether polyols, and wherein the at least one water-soluble compound is present in an amount ranging from 1% to by 60% weight, relative to the total weight of the composition,
- wherein the composition comprises a total amount of water-soluble organic components ranging from 25% to 60% by weight, relative to the total weight of the composition.
