Abstract: The present disclosure provides swellable pre-treatment compositions, printable media, and related methods. As such, a swellable pre-treatment coating for a print medium can include an evaporable solvent, a matrix, and a wax. The matrix can include from 10 wt % to 20 wt % of a fixer, from 25 wt % to 35 wt % of aluminum chlorohydrate, from 0.5 wt % to 10 wt % of a first binder, from 20 wt % to 30 wt % of a second cross-linkable binder, and from 1 wt % to 5 wt % of a cross-linker. The wax can be present at from 10 wt % to 20 wt %, The weight percentages of the matrix and the wax are based on a total amount present in the swellable pre-treatment coating after removal of the evaporable solvent.
