Abstract
An agent for improving surface quality of paper comrising an acrylamide resin composition obtained by hydrolyzing an acrylamide resin which is obtained by polymerizing an acrylamide monomer in the presence of a urea compound, or copolymerizing an acrylamide monomer and an acrylonitrile monomer; an acrylamide monomer and a cross-linking agent; or an acrylamide monomer, an acrylnitrile monomer and a cross-linking agent in the presence of a urea compound. This agent provides paper with excellent surface strength, tensile strength and internal strength far better than conventional paper quality improving agents.
