In one example, a print medium (200) includes pigment particles sized less than a hundred nanometers and frictional control additives. An undercoating (205) is disposed between the base material and top coating. The undercoat includes a first sub-layer (202) comprising a pigment fixative agent and a second sub-layer (203) comprising a dye fixative agent. The top coating forms a protective and low friction coating over the undercoating.
