Abstract: The invention features a disposable absorbent article including a thermoplastic composition applied in a full coat layer (i.e. a layer with 100% coverage) as a discrete shape to either the top sheet or to a component of the absorbent core (i.e. core or core wrap). The discrete shape is strategically located to decrease the likelihood of leaks in the desired location. The thermoplastic composition serves as a leak barrier to prevent bodily fluids and solids (i.e. urine, stool, menstrual flow, wound seepage) from leaking from the absorbent core.

Abstract: This invention claims hot melt adhesive compositions that can be used to form elastic composites that are useful in disposable absorbent articles. The hot melt adhesive compositions combine several desirable properties including low viscosity, low odor, a desirable retractive profile improved snap back) as demonstrated by low mechanical hysteresis values and acceptable adhesion. These properties make the hot melt adhesives well suited to forming elastic composites. The improved retractive profile further allows for the ability to apply a lower coat weight and still maintain the elastic properties.
