Abstract

An absorbent article, for example, a diaper, a training pant, a swimming pant, or a feminine care article, and so forth, includes a topsheet, which forms a body-facing surface of the absorbent article, a backsheet disposed distally from the topsheet, which forms a garment-facing surface of the absorbent article, an absorbent core positioned between the topsheet and the backsheet, and a heat-activatable expandable treatment on the garment-facing surface. The heat-activatable expandable treatment is present on the garment-facing surface in a visually distinctive shape or pattern and provides visual and/or tactile cues to a user of the absorbent article.
