    • A fluid dispersed suspension of clay or other negatively charged pigment or filler is produced by adding the pigment or filler to water in the presence of the combination of a nonionic surface active agent and a cationic surface active agent at an alkaline pH. The resulting suspension may be incorporated into cationic media, e.g., a solution of cationic starch, protein adhesive or cationic latex, to produce improved paper coating compositions. The suspension may be incorporated into a solution of a cationic resin to produce a conductive coating for electrographic reproduction paper. Improved optical performance and printability are obtained when the suspension is employed in the production of a filled paper product.
    • 在碱性pH下,在非离子表面活性剂和阳离子表面活性剂的组合存在下,通过将颜料或填料加入水中来制备粘土或其它带负电荷的颜料或填料的流体分散悬浮液。 所得悬浮液可以并入阳离子介质中,例如阳离子淀粉,蛋白质粘合剂或阳离子胶乳的溶液,以产生改进的纸涂层组合物。 悬浮液可以结合到阳离子树脂的溶液中以产生用于电子照相再现纸的导电涂层。 当悬浮液用于生产填充的纸制品时,获得了改进的光学性能和可印刷性。
