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;

    absorbent particulate polymer material deposited on said first and second substrates, wherein the absorbent particulate polymer material has a saline flow conductivity greater than about 100×
