Disposable composite insensitive to surface moisture but disintegratable in aqueous liquid

Image Number 2 for United States Patent #4186233.

A disposable composite comprising an absorbent, swellable film such as a lightly cross-linked polyacrylate, having on its two major surfaces a hydrophobic coating such as polyvinylidene chloride, is useful as a liner or packaging for disposable articles such as sanitary napkins. The hydrophobic coating protects the coated surfaces of the absorbent, swellable film from moisture, thereby maintaining the composite's integrity during use. Upon the composite's immersion in an aqueous fluid, the exposure of any uncoated film to water causes the composite to disintegrate, providing for easy flushability.
