Abstract
Aqueous inks containing 1,2-alkyl of from C4 to C10 diols, specifically 1,2-hexanediol or 1,2-pentanediol are employed in jet inks. Two such inks of different colors applied side-by-side to paper do not bleed and therefore give excellent image definition. The diols are not flammable, odorous or highly volatile.
