Beschreibung
Zusammenfassung:	An absorbent article comprises a backsheet and an absorbent layer, where the absorbent layer comprises a support substrate and a superabsorbent polymer composition positioned adjacent to the substrate. The absorbent layer may also include an additional substrate, and the article may additionally include a topsheet. The superabsorbent polymer composition comprises a water-soluble ionic polymer capable of sufficient non-radiative crosslinking within about 10 minutes at a temperature of about 120° C. or less to reach an absorbent capacity of at least 1 g/g as measured by the Centrifuge Retention Capacity Test. In addition, the absorbent layer is restretched. The result is an absorbent article which exhibits improved performance as well as greater comfort and confidence among the user.
