Abstract
An absorbent article (10) has a front waistband portion (14), a back waistband portion (12) and an intermediate portion (16). The article comprises a flexible backsheet member (30), and a liquid permeable topsheet layer (28). An absorbent body structure (32), with a retention portion (48), is sandwiched between the backsheet member (30) and the topsheet layer (28), and a wetness indicator (40) visually shows a presence of liquid in selected areas of the article. The wetness indicator is provided by at least one indicator section of the backsheet member (30) which includes a polymer sheet layer (96). Desirably, The wetness indicator is provided by at least one indicator section of the backsheet member (30) which includes a backsheet laminate material having a fibrous nonwoven web (94) attached to a polymer sheet layer (96). The indicator section of the backsheet member (30) includes a plurality of translucent windows (98) which are arranged in an area pattern and are formed by a selected thermal treatment of the polymer sheet layer (96). In particular arrangements, the translucent windows (98) can be arranged in an area pattern and can be formed by a bonding of the fibrous nonwoven web (94) to the polymer sheet layer (96) in the backsheet laminate material. A layer of contrast material (44) may be attached to the article at an operative location which is interposed between an intended wearer of the article and the indicator section of the backsheet member (30). In particular arrangements, the contrast layer (44) can have a first appearance through the translucent windows (98) when the contrast material is dry, and can have a visually different second appearance through the translucent windows (98) when the contrast material is wetted with water or other aqueous liquid.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
