Abstract
A coated substrate which includes a first, second, and third layer. The first layer has first and second surfaces. For example, the first layer may be a film or a nonwoven web. Desirably, the first layer will be a cellulosic nonwoven web. The second layer overlays the first surface of the first layer. The second layer is composed of from about 25 to about 70 percent by weight of a latex binder, from about 25 to about 65 percent by weight of a hydrophilic silica, from about 5 to about 20 percent by weight of a latent base, and from about 1 to about 4 percent by weight of a water-soluble viscosity modifier, in which all percents by weight are based on the total dry weight of the second layer. The third layer overlays the second layer and is composed of a water-soluble cationic polymer. Additional layers may be present, if desired.
