1. A disposable absorbent article comprising:
a topsheet and a backsheet; and an absorbent core located between the topsheet and the backsheet and comprising a first absorbent layer wherein said first absorbent layer comprises a first substrate comprising a first surface and a second surface, an absorbent particulate polymer material disposed on the second surface of the first substrate in an absorbent particulate polymer material area, and an adhesive at least partially in contact with the absorbent particulate polymer material and partially in contact with the second surface of the first substrate, wherein the first surface of the first substrate is in facing relationship with the backsheet; the disposable absorbent article having a longitudinal axis extending from a first end to a second end, wherein the basis weight of the absorbent particulate polymer material varies across the absorbent core in a direction substantially perpendicular to the longitudinal axis, the absorbent core comprises a first side absorbent zone and a second side absorbent zone spaced from one another and extending substantially parallel to the longitudinal axis and a central absorbent zone extending along the longitudinal axis and between the first and second side absorbent zones, the absorbent particulate polymer material in the first and second side absorbent zones of the absorbent core has a basis weight, the absorbent particulate polymer material in the central absorbent zone of the absorbent core has a basis weight, and the basis weight of the absorbent particulate polymer material in the first and second side absorbent zones is greater than the basis weight of the absorbent particulate polymer material in the central absorbent zone.
