First Claim
1. An absorbent article comprising:
- a chassis comprising a topsheet, a backsheet and an absorbent core located between said topsheet and said backsheet, wherein said absorbent core comprises;
a. a first layer comprising;
i. a first substrate material having a first surface and a second surface, ii. a first absorbent polymer material layer having a first surface and a second surface, and iii. a first thermoplastic composition;
wherein at least portions of said second surface of said first absorbent polymer material layer are in contact with at least portions of said first surface of said first substrate material;
wherein at least portions of said first thermoplastic composition are in contact with at least portions of said first surface of said first absorbent polymer material layer; and
b. a second layer comprising;
i. a second substrate material having a first surface and a second surface, ii. a second absorbent polymer material layer having a first surface and a second surface, and iii. a second thermoplastic composition;
wherein at least portions of said second surface of said second absorbent polymer material layer are in contact with at least portions of said first surface of said second substrate material;
wherein at least portions of said second thermoplastic composition are in contact with at least portions of said first surface of said second absorbent polymer material layer;
wherein said first layer and said second layer are combined together such that said first thermoplastic composition and said second thermoplastic composition are in direct contact with each other.

Abstract
An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed that provides an improved immobilization of absorbent polymer material when the article is fully or partially urine loaded. This absorbent core is useful for providing an absorbent article of increased wearing comfort. Specifically disclosed is an absorbent core useful for an absorbent article comprising a substrate layer and absorbent material, the absorbent material comprising an absorbent polymer material, the absorbent material optionally comprising absorbent fibrous material, the absorbent fibrous material not representing more than 20% of the weight of absorbent polymer material, wherein the absorbent material is immobilized when wet such that the absorbent core achieves a wet immobilization of more than 50%, preferably of more than 60%, 70%, 80% or 90% according to the Wet Immobilization Test described herein.
