What is claimed is: 1. A disposable absorbent article comprising:a chassis including a topsheet and a backsheet; anda substantially cellulose free absorbent core located between the topsheet and the backsheet and including absorbent polymer material, wherein the absorbent particulate polymer material has a saline flow conductivity greater than about 100×10−7 cm3·sec/g and a centrifuge retention capacity of greater than about 20 g/g;wherein the absorbent polymer material comprises absorbent particulate polymer material;the absorbent core includes first and second absorbent layers, the first absorbent layer including a first substrate and the second absorbent layer including a second substrate;the absorbent particulate polymer material is deposited on said first and second substrates;the absorbent core further comprises thermoplastic adhesive material covering the absorbent particulate polymer material on the respective first and second substrates; andsaid first and second absorbent layers are 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;wherein 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;wherein the absorbent particulate polymer material is deposited on the first and second substrates in respective patterns of land areas and junction areas between the land areas such that the absorbent particulate polymer material is discontinuously distributed on the first and second substrates; and the first and second absorbent layers are combined together such that the respective patterns of absorbent particulate polymer material are offset from one another;wherein the width of the land areas is from about 8 mm to about 12 mm and the width of the junction areas is less than about 5 mm.
