skin-facing surface; an absorbent member
that is interposed between the topsheet
and the backsheet; the sanitary napkin
contains a pair of wings longitudinally extending outward from a pair of lateral side
edges of the absorbent member, wherein
each of the wings includes a portion of the
topsheet and the backsheet; and a target
region that is disposed so as to face an excretory part of a wearer when the wearer
wears the absorbent article sanitary napkin and that is located between the pair of
lateral side edges of the absorbent member, wherein the target region is a region
formed between one root and the other
root of the wings in the longitudinal direction, wherein the absorbent member is a
hydrophilic foam body made of a hydrophobic material subjected to hydrophilic
treatment, a plurality of through holes
penetrating the absorbent member in a
thickness direction are formed at a portion
of the absorbent member that is located in
the target region, the absorbent member
has a layer-stacked structure in which a
plurality of layers are stacked in the thickness direction, a ratio of the Klemm water
absorption height as measured according to JIS P8141, of a lower layer, which
is most proximal to the backsheet, of the
layer-stacked structure to that of an upper
layer that is most proximal to the topsheet
is 2.0 or more, the backsheet is formed of
a moisture permeable film that includes
a plurality of microvoids, water repellent
finishing is performed on a portion, which
is located in the target region, of a skin-facing surface of the moisture permeable
film, so that water repellent portions are
formed, and a ratio of the total area of portions on which the water repellent finishing is performed to the area of the target
region is in the range of from 30% to 60%,
wherein the absorbent member does not
include an absorbent polymer; and its upper and lower layers are bonded to each
other and the layers are inseparably integrated with each other.

A composite material for an absorbent
article, comprising a substrate material
having a surface which is positively or
negatively electrostatically charged in a
predetermined solvent selected from a
non-polar organic solvent, a polar organic
solvent, and a mixed solvent of a polar
organic solvent and water, and a water
absorbent material adsorbed thereon by
electrostatic interaction, having a surface
which is electrostatically charged to an
electric charge opposite to that of the surface of the substrate material, wherein the
substrate material comprises a fibrous base
material or resinous base material and a
polyelectrolyte layer provided in a surface
layer thereof, and/or, the water absorbent
material has a water absorbent particulate
base material or water absorbent fibrous
base material and a polyelectrolyte layer
provided in a surface layer thereof.

A method of producing a multi-layered
absorbent article having two or more col-
ored regions, the method comprising the
steps of: a. providing an absorbent article
converting line; b. supplying a first precur-
sor web to the converting line; c. printing
a first colored region to the first precursor
web using contact printing at a contact
printing station; d. supplying a precursor
nonwoven web to the converting line; e.
producing a composite substrate from
the first precursor web and the precursor
nonwoven web; f. supplying a nonwoven
web material; g. printing a second colored
region to the nonwoven web material us-
ing non-contact printing at a non-contact
printing station; h. cutting the composite
substrate into individual sheets; i. cutting
the nonwoven web material into individ-
ual sheets; and j. combining an individual
sheet of composite substrate and an in-
dividual sheet of nonwoven material to
produce an absorbent article; wherein the
second colored region is printed to a sur-
face of the nonwoven web material that
faces the composite substrate.
