  • Patent number: 10973702
    Abstract: An absorbent article comprises a three-dimensional liquid permeable topsheet. The topsheet comprises a first layer comprising a hydrophobic material and a second layer comprising a hydrophilic material. The first layer is joined to the second layer. The topsheet comprises a plurality of recesses, a plurality of projections, and a plurality of land areas. The land areas surround at least a majority of the plurality of projections and a plurality of the recesses. The absorbent article comprises a liquid impermeable backsheet, an acquisition material, an absorbent core disposed at least partially intermediate the acquisition material and the liquid impermeable backsheet, and an indicia. The indicia is on the acquisition material or the liquid permeable topsheet. The indicia is visible from a wearer-facing side of the absorbent article. The indicia is different color than the acquisition material or the liquid permeable topsheet.
