摘要：
An absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core comprising a core wrap enclosing absorbent material comprising a superabsorbent polymer. The absorbent core comprises one or more substantially absorbent material free areas through which a portion of the top side of the core wrap is attached to a portion of the bottom side of the core wrap. The top side of the core wrap is at least colored in the portion attached by one or more core wrap bonds to the portion of the bottom side of the core wrap so that the color of the top side of the core wrap forms one or more colored areas visible from the exterior of the article. When the absorbent material swells, the core wrap bonds at least partially opens and the colored areas become less visible from the exterior of the article.
