Abstract
A disposable wearing article adapted to prevent indicators from being transferred to a liquid-absorbent structure and to make the indicators develop the color reaction quickly in response to a discharge of body exudates. A disposable diaper has a topsheet, a backsheet and a liquid-absorbent structure interposed between these top- and backsheets. A surface of a first backsheet facing the liquid-absorbent structure is formed with indicators. The indicators contain a hot-melt polymer, an indicator agent adapted to develop a color reaction and a plasticizing oil. The liquid-absorbent structure has a liquid-absorbent core, a liquid-diffusive wrapping sheet adapted to wrap the core. A hydrophilic bottom sheet is interposed between a bottom surface of the core and a bottom surface region of the wrapping sheet. A dimension in the transverse direction of the bottom sheet is larger than a dimension of a region in which the indicators are formed and smaller than a dimension in the transverse direction of the core.
