Absorbent articles

An absorbent article comprising, in sequence, a liquid pervious topsheet, an absorbent body comprising, in sequence from the top:

• an upper assembly that includes:
• an upper acquisition layer substantially free of super absorbent material, and a super absorbent layer consisting mainly of first super absorbent layer which has a Gel Layer Permeability (GLP) value of at least about 4.times.10.sup.-7 cm.sup.3 sec/gm and which is present in an amount of at least about 20 g/m2, and
• a lower assembly that includes:
• a second superabsorbent material having an Absorbent Against Pressure of at least 15 g/g at 50 g/cm.sup.2 and which comprises:
• an upper layer having void space for storage of liquid discharges, and
• a lower layer which contains second superabsorbent material and wherein at least 70% by weight of the total amount of the second superabsorbent material which is in the upper and lower layers is in the lower half of the combined thickness of the upper and lower layers, arranged with the upper acquisition layer towards the topsheet, and
• a liquid impervious backsheet.

An absorbent article comprising, in sequence, a liquid pervious topsheet, an absorbent body comprising, in sequence through its thickness from the top:

• an upper assembly comprising:
• an upper layer comprising a first porous material having a wet compressibility of at least 5 cm.sup.3 g.sup.-1 and a drip capacity of at least 10 g/g, the assembly also comprising a first superabsorbent material having a substantially non-decreasing Dynamic Swelling Rate, and
• a lower assembly comprising:
• a second porous material and a second superabsorbent material having a dynamic swelling rate of at least 0.2 g/g/s and an absorption constant against pressure of at least 15 g/g at 50 g/cm.sup.2 (0.7 psi),
• wherein the Dynamic Swelling Rate of the second superabsorbent material is at least 1.5 times the Dynamic Swelling Rate of the second superabsorbent material, arranged with the upper layer towards the topsheet and
• a liquid impervious backsheet.
