Abstract
A wetness indicating composition comprising a colorant disposed in a carrier matrix. The colorant provides a visible signal when activated by urine. The colorant resists leaching from the carrier matrix by being chemically bound to a component of the carrier matrix. The colorant may be bound by ionic or covalent bonds, or by intermolecular forces. The colorant may be a pH indicator. The wetness indicating composition may be incorporated into a wearable article, such as a disposable absorbent article.
