Abstract (en)

[origin: WO9957371A1] A paper liner for a plasterboard has a base paper with a surface size applied to one surface. The surface size includes oxidized starch, as sizing agent selected from the group consisting of alkenyl succinic anhydride, succinic anhydride, wood rosin, alkyl ketene dimer and mixtures thereof, and an acrylic containing polymer. A coating including at least one inorganic filler and at least one binder is applied to the side of the paper having the external surface size. The surface size and coating are sufficiently porous to enable drying of the gypsum slurry used in manufacture of the plasterboard. The paper also provides a surface that can be printed with a decorative pattern and does not require painting or wall papering to provide and esthetically pleasing appearance.
