A disposable diaper having front and rear augmented waistband zones having a specified size and stiffness is disclosed. For relatively thinner, less bulky diapers of currently marketed designs, providing augmented waistband zones is believed to reduce mental and physical effort for the caregiver in application of the diaper. The augmented waistband zones provide a robust-feeling structure proximate the waist edges, which the caregiver may grasp at front and rear to adjust the diaper on the wearer. Caregiver perception of a need to reach deeper into the diaper structure to grasp it at a thicker area to tug at it is believed to be reduced.

Provided is a water-absorbing agent which maintains a certain degree of liquid permeability and water absorption speed while also reducing re-wet in a disposable diaper, without the use of costly raw materials or costly apparatuses. The water-absorbing agent of the present invention contains a polyacrylic acid salt-based water-absorbing resin as a main component and has physical properties falling within a specific range, the physical properties being saline flow conductivity (SFC), gap fluid retention property under pressure, and a proportion of particles having a particle diameter of not less than 150 μm and less than 710 μm.

Provided is an absorbent article having excellent shape retention of an absorber even when an external force is applied thereto. The present invention is an absorbent article having: an aqueous-liquid absorbing part having crosslinked polymer particles having as essential constitutional units thereof a water-soluble vinyl monomer and/or a vinyl monomer which became the water-soluble vinyl monomer by hydrolysis, and a crosslinking agent; and a nonwoven fabric having porous fibers as an essential constituent thereof, the crosslinked polymer particles preferably absorbing 40 times the weight thereof of physiological saline 40 in 40-150 seconds.

A water permeability-imparting agent containing an alkylene oxide adduct (A) of a polyvalent active hydrogen compound represented by Formula (1):

R—[O(A.sup.1O).sub.m—(CH.sub.2CH.sub.2O).sub.n—H].sub.1   (1)

wherein R represents a residue, after removal of all active hydrogen, of the polyvalent active hydrogen compound; A.sup.1O represents a C2 to C4 alkyleneoxy group; m represents an average addition mole number of A.sup.1O and is a number of 4 to 50; n represents an average addition mole number of CH.sub.2CH.sub.2O; and 1 represents a valence and is an integer of 3 to 6, and an average addition mole number ratio between A.sup.1O and CH.sub.2CH.sub.2O in Formula (1), n/m, is 0 to 0.5.

Arrays of absorbent articles having signals or combinations of signals that help communicate functional features of the component article, including the presence and/or absence of channels.

A pant type disposable absorbent product comprising a front body panel, a back body panel positioned at a distance from said front body panel, and an absorbent member; said absorbent product having a longitudinal central axis X-X and a transverse central axis Y-Y; said front body panel being substantially rectangular, and having a waist edge, two side edges, and an inward edge comprising a crotch edge, and leg opening edges on each side of the crotch edge, between the crotch edge and each side edge, said front body panel being at least partially elasticized, said back body panel having a waist edge, two side edges, a crotch edge, and leg opening edges on each side of the crotch edge, between the crotch edge and each side edge, wherein a distance from the crotch edge to the waist edge is greater than the length of the side edges.

Both high air permeability and high peeling strength are achieved.

The above problem is solved by providing an underpants-type disposable diaper including a stretchable region (80) stretchable at least in one direction in an outer body (20), in which the stretchable region (80) is formed by stacking an elastic film (30) between a first sheet layer (20A) composed of a nonwoven fabric and a second sheet layer (20B) composed of a nonwoven fabric, and in a state in which the elastic film (30) is stretched in the stretching and contracting direction, the first sheet layer (20A) and the second sheet layer (20B) are joined via through holes (31) formed in the elastic film (30) at a large number of sheet bond portions (40) arranged at intervals in each of a stretching and contracting direction and a direction orthogonal thereto, and in the sheet bond portions (40), the first sheet layer (20A) and the second sheet layer (20B) are joined at least by a melted and solidified material (30m) of the elastic film (30) among the first sheet layer (20A) and the second sheet layer (20B).

An absorbent article comprising a composition, said composition comprising a metathesized unsaturated polyol ester, said metathesized unsaturated polyol ester having one or more of the following properties: (i) a weight average molecular weight of from about 5,000 Daltons to about 50,000 Daltons; (ii) an oligomer index from greater than 0 to 1; (iii) an iodine value of from about 30 to about 200.
