AQUEOUS MEDIUM-SENSITIVE COATING COMPOSITIONS FOR TRIGGERED RELEASE OF ACTIVE INGREDIENTS AND VISUAL INDICATION FOR WETNESS

摘要

An absorbent article includes a topsheet layer, a backsheet layer and one absorbent core layer. The topsheet layer, absorbent core layer and backsheet layer each include a longitudinally directed side peripheral edge. The absorbent article further includes an aqueous medium-sensitive coating composition for triggered release of active ingredients from the absorbent article. The aqueous medium-sensitive coating composition is affixed to the absorbent article adjacent a longitudinally directed side peripheral edge. The coating composition includes a betaine ester or betaine ester derivative having a functional active group derived from a fragrance with a hydroxyl group, a color changing visual indicator chemistry, where the visual indicator chemistry is selected from at least one of the group of a pH indicator dye and pH adjuster, a thermochromic dye and a polarity-sensitive dye.

主权项

1. An aqueous medium-sensitive, coating composition for triggered release of an active ingredient and visual indication of the presence of aqueous medium, comprising:
a betaine ester or betaine ester derivative including a fragrance radical; and a visual, color changing wetness indicator, which changes color from a first color to a second color upon a change of condition, wherein said visual, color changing wetness indicator includes at least one of a pH indicator dye and pH adjuster, a thermochromic dye, and a polarity-sensitive dye.
