Ink jet inks and printing processes

摘要: Disclosed is an ink composition which comprises aqueous liquid vehicle, a colorant, and additive material selected from the group consisting of (a) symmetric acetylenic bisester alcohols, (b) bisalkyl alcohols bisalkoxy (c) bisamido (d) (e) mono amido (f) trialkylhydroxy compounds, (g) derivatives 1,2-diols 1,3-diols, (h) thio diols, (i) aromatic (j) heterocyclic (k) imino (l) salts hydroxyl (m) saccharides saccharide derivatives, (n) mixtures thereof. Also disclosed jet process (1) incorporating into thermal printing apparatus aforementioned composition; (2) causing droplets to be ejected in imagewise pattern onto substrate, thereby generating images on substrate. Further substrate; (3) exposing substrate microwave radiation, drying
