Abstract: A recording medium includes a protective layer and a porous ink receiving layer. The protective layer includes a first binder and a first set of polymeric beads. The first set of polymeric beads has an average volume-based particle size equal to or greater than ten microns. The protective layer has a coat weight equal to or less than three grams per square meter. The recording medium also includes a porous ink receiving layer including a first set of pigments and a second binder.

Abstract: The present disclosure provides pre-treatment compositions and related methods. As such, a pre-treatment coating for a print medium can include a an evaporable solvent, a matrix, and a wax. The matrix can include from 5 wt % to 20 wt % of a fixer, from 5 wt % to 20 wt % of a low Tg latex, and from 30 wt % to 80 wt % of a high Tg latex. The wax can include from 5 wt % to 30 wt % of a wax. The weight percentages of the matrix and the wax are based on a total amount present in the pre-treatment coating after removal of solvent.
