Beschreibung
Zusammenfassung:	A wetness indicating composition is disclosed that changes color in response to a change in pH. The composition comprises a water-insoluble, thermoplastic polymer composition, a superabsorbent polymer, a wetness indicator, and surfactant. The wetness indicating composition is useful in disposable absorbent articles, e.g., disposable diapers, feminine napkins, medical dressings and beddings for humans and animals. La présente invention concerne une composition indiquant l~humidité qui change de couleur en réponse à une modification de pH. Ladite composition comprend une composition polymère thermoplastique insoluble dans l~eau, un polymère superabsorbant, un indicateur d~humidité et un agent de surface. Ladite composition indiquant l~humidité est utile dans des articles absorbants jetables, par exemple des couches jetables, des serviettes hygiéniques, des pansements médicaux et des articles de literie pour êtres humains et animaux.
