Abstract
An absorbent article having a longitudinal axis extending in a longitudinal direction and a transversal axis extending in a transversal direction perpendicular to the longitudinal direction. The absorbent article comprises a fluid-permeable topsheet, a lotion on the topsheet having a lotion pattern covering a lotion pattern area, a fluid-impermeable backsheet, and an absorbent core between the topsheet and the backsheet. The core wrap defines a core footprint in a plane parallel to the longitudinal direction and transversal direction. The article comprises an intermediate layer between the topsheet and the absorbent core, the intermediate layer comprising at least one longitudinally-extending channel, preferably at least a pair of longitudinally-extending channels disposed symmetrically on each side of the longitudinal axis. The topsheet is depressed in the channel(s). The lotion-to-channel overlap ratio ranges from 0% to 20% of the area of the channel(s). The lotion-to-channel overlap ratio is the percentage of the channel(s) of the intermediate layer overlapping with the lotion pattern.
