Abstract

Printing paper such as newspaper printing paper, the water absorbency of which is controlled by coating material for controlling water absorbency on the surface of base paper, wherein the coating material contains component A which is at least one water-soluble polyacrylamide selected from nonionic polyacrylamides, cationicpolyacrylamides, and water-solublepolyacrylamides, and component B which is water-soluble anionic polymers of monomers having hydrophobic substitute(s) and monomers having at least carboxyl group(s) or sulfone group(s).
