Patent ID: 10286712

Abstract:
A coated print medium can include a base stock having a basis weight of 35 gsm to 250 gsm, and a coating layer applied to the base stock at from 1 gsm to 50 gsm by dry weight. The base stock can include from 65 wt % to 95 wt % cellulose fiber with 20 wt % to 100 wt % being mechanical pulp, and from 5 wt % to 35 wt % inorganic pigment filler. The coating layer can include inorganic pigment particles having an average equivalent spherical diameter from 0.2 μm to 3.5 μm; a fixative agent including metal salt, cationic amine polymer, quaternary ammonium salt, quaternary phosphonium salt, or mixture thereof; and a polymer blend including water soluble polymer and water dispersible polymer having a Zeta potential greater than −40 mV, wherein a weight ratio water soluble polymer to water dispersible polymer is from 1:25 to 1:1.
