Abstract
Official abstract text for this publication.
Provided is an ink composition for inkjet printing, comprising a coloring material, water, an organic solvent, resin fine particles, and a surfactant, wherein the organic solvent includes a first organic solvent and a second organic solvent that is different from the first organic solvent, wherein a total amount of the first organic solvent and the second organic solvent is 90 mass % or more in the organic solvent, wherein the first organic solvent is propylene glycol, wherein the second organic solvent has a boiling point of 120 to 200° C., and includes at least one of glycols, glycol ethers, or methoxybutanols, and wherein a content of the first organic solvent is 15 to 50 mass % in the ink composition.
First claim
Opening claim text (preview).
1 . An ink composition for inkjet printing, comprising a coloring material, water, an organic solvent, resin fine particles, and a surfactant, wherein the organic solvent includes a first organic solvent and a second organic solvent that is different from the first organic solvent, wherein a total amount of the first organic solvent and the second organic solvent is 90 mass % or more in the organic solvent, wherein the first organic solvent is propylene glycol, wherein the second organic solvent has a boiling point of 120 to 200° C., includes at least one of glycols, glycol ethers, or methoxybutanols, and includes at least one of propylene glycol monomethyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol tertiary butyl ether, or 3-methoxy-1-butanol, and wherein a content of the first organic solvent is 15 to 50 mass % in the ink composition, wherein a content of the second organic solvent is 20 to 40 mass % in the ink composition. 2 . The ink composition for inkjet printing according to claim 1 , wherein the surfactant includes at least one of a nonionic surfactant or a silicone-based surfactant. 3 . The ink composition for inkjet printing according to claim 1 , wherein the resin fine particles include at least one of wax or emulsion. 4 . The ink composition for inkjet printing according to claim 2 , wherein the resin fine particles include at least one of wax or emulsion.
