Abstract
A nano-pigment inkjet ink composition that has a low odor and is environmentally-friendly includes, based on total weight of the inkjet ink composition, from 1 to 10 percent by weight of N-ethyl pyrrolidone; from 1 to 20 percent by weight of propylene carbonate; from 50 to 80 percent by weight of a glycol ether solvent; a pigment that is a nano-pigment having a nano-particle size; a dispersant; a resin; a plasticizer; a surfactant; and from 0.1 to 3.0 percent by weight of an acidity regulator that is at least one cyclic tertiary amine compound. This inkjet ink composition meets both environmental and print quality requirements. The composition has a high flash point and includes raw materials having low toxicity and low odor. It has good storage stability, inkjet stability, and good print quality. Printhead nozzles are not easily clogged. The printed image has high gloss, scratch resistance, and weather resistance.
