Abstract

An absorbent article has a planar direction and a thickness direction. The absorbent article includes a volatile first functional component, a volatile second functional component, water-disintegrable microcapsules that contain the second functional component, and a solvent that keeps the second functional component contained inside the microcapsules. Between a liquid-permeable layer and an absorption layer, the absorbent article has functional composition coated regions that extend in the planar direction and that are coated with the functional composition, and has adhesive coated regions that extend in the planar direction and that are coated with an adhesive. The adhesive coated regions have an adhesive region that directly or indirectly joins the liquid-permeable payer and the absorption layer.

Dependent claims

An absorbent article including a liquid-permeable layer, a liquid-impermeable layer, an absorbing layer between the liquid-permeable layer and liquid-impermeable layer, and a functional composition, the absorbent article having a planar direction and a thickness direction,

wherein the functional composition includes a volatile first functional component, a volatile second functional component, water-disintegratable microcapsules encapsulating the second functional component, and a solvent that keeps the second functional component encapsulated in the microcapsules,
the absorbent article has a functional composition-coated region in which the functional composition has been coated, extending in the planar direction between the liquid-permeable layer and the absorbing layer, and an adhesive-coated region in which an adhesive has been coated, and
the adhesive-coated region has an adhered region in which the liquid-permeable layer and the absorbing layer are directly or indirectly adhered.

Dependencies are inferred from the claim text.
