The present disclosure is drawn to a coated print medium, a method of preparing a print medium, and a printing system. The coated print medium can comprise a substrate and a coating applied to the substrate. The coating can comprise, by dry weight, 5 wt % to 30 wt % of a polymeric binder, 20 wt % to 50 wt % of a cationic latex, 5 wt % to 15 wt % of a multivalent cationic salt, 1 wt % to 20 wt % of an optical brightener, and 1 wt % to 10 wt % of an anti-quenching agent selected from the group consisting of a sulfonated diphenyloxide, polyvinyl pyrrolidone, and combination thereof. In this example, if the polymeric binder is polyvinyl pyrrolidone, the anti-quenching agent is the sulfonated diphenyloxide.

A print medium can include a cellulose-based paper substrate with a first surface and a second surface opposite the first surface. The first surface can be treated with an electrically charged treatment layer. An ink-absorbing layer can be positioned on the electrically charged treatment layer. The ink-absorbing layer can include a polymeric binder and surface-activated fumed silica particles. The surface-activated fumed silica particles can include fumed silica particles that are surface-activated with charged multivalent aluminum salt and organosilane reagent.
