Description

ABSTRACT:
A disposable diaper which is capable of providing a readily visible indication when wet which includes a strip of moisture absorbing paper of a selected water insoluble color, or carrying a water insoluble printed pattern on its inner side, the strip being inserted between the absorbent pad of the diaper and the translucent moisture-impervious outer layer. So long as the diaper is dry, the pattern is covered by the carrier strip, and is not visible. However, when the diaper is wet, the carrier strip absorbs the moisture and becomes transparent, so that the pattern is visible through the translucent outer layer not only that the diaper is wet, but the degree of wetness.
