1. A disposable absorbent article comprising:
- a chassis including a topsheet and a backsheet; and
a substantially cellulose free absorbent core located between the topsheet and the backsheet and including first and second absorbent layers, the first absorbent layer including a first substrate and the second absorbent layer including a second substrate, the first and second absorbent layers further including superabsorbent particulate polymer material deposited on said first and second substrates and thermoplastic adhesive material covering the absorbent particulate polymer material on the respective first and second substrates, said first and second absorbent layers combined together such that at least a portion of said thermoplastic adhesive material of said first absorbent layer contacts at least a portion of the thermoplastic adhesive material of said second absorbent layer, the absorbent particulate polymer material is disposed between the first and second substrates in an absorbent particulate polymer material area, and the absorbent particulate polymer material is substantially continuously distributed across the absorbent particulate polymer material area.

19. A method of making a disposable absorbent article comprising:
-
depositing absorbent particulate polymer material on a first substrate in a first pattern to form a first absorbent layer such that the absorbent particulate polymer material is discontinuously distributed on the first substrate; depositing absorbent particulate polymer material on a second substrate in a second pattern to form a second absorbent layer such that the absorbent particulate polymer material is discontinuously distributed on the second substrate; depositing a thermoplastic adhesive material on the absorbent particulate polymer material and the first and second substrates to cover the absorbent particulate polymer material on the first and second substrates; and combining said first and second absorbent layers together such that at least a portion of said thermoplastic adhesive material of said first absorbent layer contacts at least a portion of the thermoplastic adhesive material of said second absorbent layer, the absorbent particulate polymer material is disposed between the first and second substrates in an absorbent particulate polymer material area, and the absorbent particulate polymer material is substantially continuously distributed across the absorbent particulate polymer material area. - View Dependent Claims (20, 21)
