Disclosed is a low cool curl microwave dryable ink suitable for use in Thermal Ink Jet (TIJ) printing applications. The ink formulations use triethanolamine (TEA) in high concentration 015 wt"/.) as the anti-curl additive and sodium bromide as the coupling salt. TEA is inexpensive, relatively nontoxic and readily available. TEA is a satisfactory solvent for the sodium bromide @Jar) coupling salt. Test inks, in large solid area draw down prints, remain flat after ambient drying for 24 hours. This result is as good as inks with, for example, 20% TMP (trhethylolpropane).
