An ink jet ink composition comprises water; a colorant selected from the group consisting of a dye, a pigment, and a mixture of a dye and pigment; and a material selected from the group consisting of (1) a hydroxyamide derivative having at least one hydroxyl group and at least one amide group; (2) a mercaptoamide derivative having at least one mercaptol group and at least one amide group; (3) a hydroxythioamide derivative having at least one hydroxyl group and at least one thioamide group; (4) a mercaptothioamide derivative having at least one mercaptol group and at least one thioamide group; (5) an oxyalkylene(alkyleneoxide) reaction product of the above said derivatives; (6) a thioalkylene(alkylenesulfide) reaction product of the above said derivatives; and (7) mixtures thereof. The inks comprising the said ink jet ink composition exhibit good latency especially in a high resolution thermal ink jet printhead (e.g., 600 spi) and can be printed onto a print substrate either with or without heat for the drying to give excellent images with reduced curl and cockle.
