    • Methods for increasing one or more barrier properties of a sheet of paper or paperboard, which method comprises (a) preparing a dispersion having a cationic zeta potential by combining (1) a mixture containing one or more anionic pigments with (2) one or more polyamine-epihalohydrin cationic wet strength resins; (b) coating at least one side of the sheet of paper or paperboard with the dispersion at a coating weight of from about 0.1 g/m2 to about 20 g/m2; (c) drying the coated sheet of paper or paperboard; (d) coating the dried sheet of paper or paperboard with a functional barrier top coating formulated to provide resistance to one or more of the following (1) liquid water, (2) water vapor, (3) oil, (4) grease, (5) gas permeability, (6) skid, or (7) static. Also claimed are dispersions used in the methods, which dispersions have a cationic zeta potential for use as a preliminary coating on a sheet of paper or paperboard in advance to a functional barrier top coating, which dispersions comprise: (a) a mixture containing: (i) one or more anionic pigments in an amount of at least about 20% dry weight of the anionic pigment-containing mixture, (ii) one or more neutral or cationic water soluble binders in an amount up to about 80% dry weight of the anionic pigment-containing mixture, and (b) one or more polyamine-epihalohydrin cationic wet strength resins in a weight ratio of resin:anionic pigment from about 0.03:1 to about 0.8:1.
    • 提高一张纸或纸板的一种或多种阻隔性能的方法,该方法包括(a)通过将(1)含有一种或多种阴离子颜料的混合物与(2)一种或多种阴离子颜料混合来制备具有阳离子ζ电位的分散体 多胺 - 表卤代醇阳离子湿强度树脂; (b)以约0.1g / m 2至约20g / m 2的涂层重量涂覆该纸或纸板的至少一面与分散体; (c)干燥涂布的纸或纸板; (d)用干燥的纸或纸板涂覆功能性阻隔面涂层,其被配制成对以下(1)液态水中的一种或多种,​​(2)水蒸气,(3)油,(4)润滑脂, (5)透气性,(6)防滑,或(7)静电。 还要求的是在方法中使用的分散体,其分散体具有阳离子ζ电位,用作预先在功能性屏障顶涂层上的纸或纸板上的预涂层,该分散体包含:(a)含有:( i)一种或多种阴离子颜料的含量为至少约20%的含阴离子颜料的混合物的干重,(ii)一种或多种中性或阳离子水溶性粘合剂,其量至多约80% 含有阴离子颜料的混合物,和(b)一种或多种多胺 - 表卤代醇阳离子湿强度树脂,其树脂:阴离子颜料的重量比为约0.03:1至约0.8:1。
