Abstract: The present disclosure is drawn to ink compositions including an aqueous liquid vehicle, from 1 wt % to 9 wt % pigment dispersed in the aqueous liquid vehicle by an ionic polymeric dispersant associated with pigment, from 0.5 wt % to 5 wt % non-ionic polymeric binder having a weight average molecular weight from 400 Mw to 20,000 Mw, and from 0.1 wt % to 1.5 wt % monovalent salt.

Abstract: An example of an ink supply includes an ink chamber containing a liquid ink, a salt chamber containing a salt solution, a separator positioned between the liquid ink and the salt solution, and a release mechanism. The separator completely separates the liquid ink from the salt solution prior to the release mechanism being triggered. The release mechanism has a triggered position and a retracted position. The triggered position causes the separator to at least partially open, and enables the liquid ink and the salt solution to be combined to form a mixture.
