The present invention relates to absorbent articles, typically for feminine protection, comprising a topsheet, a backsheet, an absorbent element positioned between the topsheet and the backsheet, and at least a fluid acquisition/distribution layer. The absorbent article also comprises edge barrier elements for intercepting fluids. The edge barrier elements comprise a liquid absorbent thermoplastic composition comprising a polymeric base material having particles of water-insoluble water-swellable absorbent material dispersed therein, and are comprised between the absorbent core and the at least one fluid acquisition/distribution layer.

What is claimed is: 1. An absorbent article having a longitudinal axis and a transverse axis, said absorbent article comprising a topsheet, a backsheet, an absorbent core positioned between said topsheet and said backsheet, and at least a fluid acquisition/distribution layer; wherein said absorbent article further comprises at least a first and a second edge barrier element for intercepting fluids, said at least first and second edge barrier element being positioned on opposing sides of said longitudinal axis and/or of said transverse axis; wherein said at least first and second edge barrier elements comprising a liquid absorbing thermoplastic composition which comprises a polymeric base material having particles of water-insoluble water-swellable absorbent material dispersed therein; wherein said absorbent article further comprises an upper fluid acquisition/distribution layer positioned between said topsheet and said absorbent core, a lower fluid acquisition/distribution layer positioned between said backsheet and said absorbent core, at least a first and a second edge barrier element positioned between said upper fluid acquisition/distribution layer and said core, and at least a first and a second edge barrier element positioned between said lower fluid acquisition/distribution layer and said absorbent core. 2. An absorbent article according to claim 1, wherein each of said at least first and second edge barrier elements comprise at least two parallel stripes. 3. An absorbent article according to claim 1, wherein said at least first and second edge barrier elements are positioned on opposing sides of said longitudinal axis, and each of said first and second edge barrier elements laterally extends partially outside a respective longitudinal edge margin of said absorbent core and/or of said fluid acquisition/distribution layer. 4. An absorbent article according to claim 3, wherein each of said first and second edge barrier element laterally extends along its entire length partially outside the respective longitudinal edge margin of said absorbent core, or of said liquid acquisition/distribution layer. 5. An absorbent article according to claim 1, wherein said at least first and second edge barrier elements are positioned on opposing sides of said longitudinal axis, and each of said first and second edge barrier elements laterally extends partially outside a respective longitudinal edge margin of said absorbent core, wherein said fluid acquisition/distribution layer is wider than said absorbent core. 6. An absorbent article according to claim 1, wherein said at least first and second edge barrier elements are positioned on opposing sides of said longitudinal axis, and each of said first and second edge barrier element laterally extends partially outside a respective longitudinal edge margin of said fluid acquisition/distribution layer, wherein said absorbent core is wider than said fluid acquisition/distribution layer. 7. An absorbent article according to claim 1, wherein said at least first and second edge barrier elements overall cover an area not more than about 60 cm2.
