<p>A toilet article comprises a sheet-like material (1), a pressure sensitive adhesive layer (2) formed on the sheet-like material (1) and hydrogel formable polymer layer (3) formed on the surface of the pressure sensitive adhesive layer (2). The sheet-like material (1) may be a film obtained from flexible synthetic resin such as polyethylene, polypropylene, polyester, polyamide, polyurethane, polyvinyl alcohol, rayon, polyvinyl chloride, a sheet of an unwoven fabric or a woven fabric, or a porous film. The pressure sensitive adhesive layer (2) is sticky and may be an acrylic resin adhesive, a polyester resin adhesive, a rubber adhesive or an elastomeric adhesive. The hydrogel formable polymer is a substance which forms gel when water is applied to it and has a water retention characteristic of between ten times and one hundred times. Typically, usable hydrogel substances are crosslinked substances of alkali metal salt of carboxymethylcellulose, alkali metal salt of polyacrylic acid, crosslinked substance of polyalkylene oxide, cellulose, carboxylic alkali metal salt formed from acrylonitrile graft polymer, starch-acrylonitrile substance, any of which has a good water absorbent and water retention. The hydrogel formable polymer layer may have cosmetics in a water free condition contained therein or coated on the surface thereof.</p> |
