Abstract
An absorbent element for disposable absorbent articles composed of hydrophilic fibres and a discontinuous layer of particles of a hydrogelling absorbent material disposed on the upper surface of the element including two side regions situates at least in correspondence with the central part of the element, in which the hydrogelling absorbent material is distributed at a greater concentration on the surface or within the element. When the absorbent element is used as an absorbent pad for disposable diapers, the two side regions are situated at least in the crutch region of the diaper so as to ensure more effective lateral leak-proofing.
