A method for improving one or more surface properties of a sheet of paper or paperboard, the method comprising: (a) at least one side of the paper or paperboard sheet, (1) one or more anionic pigments A dispersion having a positive zeta potential formed by combining (2) one or more polyamine-epihalohydrin cationic wet strength resins with a mixture containing from about 0.1 g / m 2 to about 20 g / m 2 Coating with a coating amount; (b) drying the coated paper or paperboard sheet; (c) one of: liquid water, water vapor, gas permeability, oil and grease, slipping, and static electricity Or applying a functional barrier top coating that is resistant to more than one, or an anionic latex pigment coating that provides improved opacity, whiteness, or printability The invention also encompasses the dispersion as well as paper or paperboard coated with the dispersion. |
