    • 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.
    • 吸收性物品(10)具有前腰带部分(14),后腰带部分(12)和中间部分(16)。 该制品包括柔性底片构件(30)和透液性顶片层(28)。 具有保持部分(48)的吸收体结构(32)被夹在底片部件(30)和顶片层(28)之间,并且湿度指示器(40)在视觉上表现出在 文章。 湿度指示器由包括聚合物片层(96)的底片构件(30)的至少一个指示器部分提供。 理想地,湿度指示器由底片构件(30)的至少一个指示器部分提供,其包括具有附接到聚合物片层(96)的纤维非织造纤维网(94)的底片层压材料。 底片构件(30)的指示部包括多个半透明窗(98),它们以区域图案布置并且通过聚合物片层(96)的选择的热处理形成。 在具体布置中,半透明窗口(98)可以以区域图案布置,并且可以通过将纤维非织造纤维网(94)粘合到底片层压材料中的聚合物片层(96)而形成。 一层造影材料(44)可以在介于物品的预期佩戴者和底片构件(30)的指示器部分之间的操作位置处附接到物品。 在特定布置中,当对比材料干燥时,对比层(44)可以具有通过半透明窗(98)的第一外观,并且当对比材料被润湿时可以通过半透明窗(98)具有视觉上不同的第二外观 与水或其他水性液体。
