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.
