Abstract
An embodiment of the invention is concerned with an aqueous inkjet ink containing an ink solvent containing water and a water-soluble organic solvent containing glycerin and triethylene glycol and a pigment dispersed in the ink solvent. The water-soluble organic solvent accounts for from 30 to 80% by weight of the ink solvent, a weight of the triethylene glycol is from 0.5 to 1.5 times the weight of the glycerin, and the pigment is blended in an amount of from 2 to 20% by weight of the total weight of the ink.
