Drop‐on‐demand ink‐jet inks made from dyes generally show poor light and wet fastness. A number of studies have been carried out previously to improve the fastness of such inks by introducing novel dyes and new additives. Based on the research results, use of fast dyes could give ink‐jet inks with good properties. This study describes new black dyes for aqueous ink‐jet inks, which show better light and wet fastness and print quality, compared to an analogous ink formulated from CI Food Black 2.
