ABSTRACT:
There is described an aqueous ink of the type useful for drop-on-demand printers, that is, comprising more than 40 weight % humectant and a compatible dye. The ink is improved by the addition of from about 0.5 to about 10 weight % of a non-ionic, acetylenic diol surfactant or a dioctyl sulfosuccinate surfactant, effective to provide high quality image properties when printed on plain paper. Without the surfactant, such high quality image is not achieved on the plain paper.
