Abstract:
1. An absorbent article that comprises a body portion that includes a liquid permeable topsheet, generally liquid impermeable backsheet, absorbent core positioned between the backsheet and the topsheet, and optionally a release liner coated with a release agent, wherein the backsheet, the release liner or both comprise water-sensitive elastic film comprising: at least one water-soluble polymer, wherein the water-soluble polymer has a weight average molecular weight of from about 10,000 to about 150,000 grams per mole and a number average molecular weight of from about 1,000 to about 80,000 grams per mole; at least one plasticizer, wherein the weight ratio of the water-soluble polymer to the plasticizer is from about 1 to about 50; and at least one thermoplastic polyurethane synthesized from at least one polyol and at least one organic diisocyanate, wherein the weight ratio of the water-soluble polymer to the thermoplastic polyurethane is from about 0.1 to about 2.5.
