Beschreibung
Zusammenfassung:	The present invention provides a composition comprising an ion-trigger polymer coating joined to a water-sensitive substrate. When the composition is employed as a diaper outercover or a pantiliner baffle, for example, the ion-trigger coating is oriented toward the body and is exposed to bodily fluids. The coating inhibits the transport of the fluids to the inner, body-side water-sensitive substrate, maintaining the structural integrity of the composition. When the entire article is disposed of in a large volume of water, such as in the hydraulic flow of a toilet, both the water-sensitive substrate layer and the ion-trigger polymer coating layer mechanically weaken and break apart into small pieces.
