PRINTING PAPER AND NEWSPRINT PAPER WITH IMPROVED WATER ABSORPTIVITY AND THE MANUFACTURING PROCESS

摘要

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