<p>A print medium includes a first layer on at least one of a first side and a second side of a substrate and a second layer. The first layer consists essentially of at least 80% by dry weight of one or more particulate inorganic pigments (PIPs). A combination of a particle size and a coat weight of the first layer on the substrate yields an effective pore size of the first layer in a range of about 0.008 to about 0.5 microns. For two or more PIPs in the first layer, the average particle size of one of the PIPs differs by no more than about 50% from the average particle size of another of the PIPs. The second layer is on top of the first layer and includes a particulate inorganic pigment (PIP) having an average particle size of about 0.1 to about 2 microns.</p>
