An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.

Absorbent articles having channel-forming areas and wetness indicator

A package comprising a plurality of disposable absorbent articles contained in an outer wrap is disclosed. The outer wrap is formed of a film having a thickness and has a path of scoring that partially but not completely penetrates the thickness, and defines a path of weakness in the film along which tear propagation is facilitated.

Humidity-stable package of disposable absorbent articles with wetness indicators

An absorbent article comprising an absorbent core having at least two longitudinally extending channel-forming areas and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid the core wrap forms channels along these areas substantially free of absorbent material.

The present invention relates to wetness indicator compositions that comprise at least one leuco dye and one color developer in a hot-melt adhesive matrix. Upon contact with water or with water-containing fluids, said wetness indicator compositions are apt to change their color from a colorless state to a colorful state or from a first colored state to a second colored state having a color different from the first one; in particular, from a first colorless, white, or translucent state to a second state having a visible color, or vice versa. The disclosed wetness indicator compositions can be used as wetness/fluid indicators in various applications, e.g. in packaging articles and in absorbent articles; in an absorbent mat or sheet or operatory cloth for medical use; in a wound dressing product; in an absorbent mat or sheet for food products.

Wetness indicator compositions comprising leuco dyes

An absorbent article comprising an absorbent core having at least two longitudinally extending channel-forming areas and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid the core wrap forms channels along these areas substantially free of absorbent material. The wetness indicator is placed between the channel-forming areas or between at least one channel-forming area and at least one longitudinally extending side edge of the article, as seen for the exterior of the article.

An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the article further comprises at least two volume indicators, and wherein at least one volume indicator comprises a masking layer comprising a water-soluble colorant and a stationary color layer comprising a permanent colorant.
