Abstract
The requirements of offset-printability for the newsprint are increasing due to the higher use of DIP (deinking pulp) and more use of color offset printing.
In this study, we would like to explore the new paper chemicals for newsprint, which fulfill the requirement of current industrial demand. They are the sizing agent (SIZEPINE N-780) and strength agent (POLYSTRON 1208) for internal use, and water resistant polyacrylamide (POLYMERSET 53 N) and surface sizing agent (POLYMERON NS-25) for gate-roll sizepress.
