ABSTRACT:
The printing sheet of the invention comprises a base sheet and two successive coating layers provided thereon, of which the first coating layer, which serves as a water-absorbing layer, is formed of a dispersion of a powdery highly water-absorptive resin, e.g., poly(sodium acrylate), in a polymeric vehicle and the second coating layer, which serves as a water absorption-controlling layer, is formed of a dispersion of an inorganic powder such as silica in a polymeric vehicle. By virtue of the adequately controlled velocity and capacity of water absorption, the printing sheet can give a very satisfactory printed matter in respect of the color density and sharpness of the printed patterns when it is used in printing on an ink-jet printer by using an aqueous ink.
