| 发明名称 | Absorbent article | ||
| 摘要 | An absorbent article includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body between the liquid-permeable top sheet and liquid-impermeable back sheet. The top sheet exhibits a color difference in a range of 37-80, based on the L*a*b* color system and measured from a skin contact surface of the top sheet in a liquid dropping test. Further, the top sheet has a color-reducing agent having an IOB of 0.00-0.35, a melting point of no higher than 45° C. and a water solubility of 0.00-0.05 g in 100 g of water at 25° C. The absorbent article is configured to allow a user to visually confirm reduction in residue of highly viscous menstrual blood on the top sheet after its absorption, thereby providing reassurance to the user. | ||
