The invention includes a hot melt adhesive composition including an olefin polymer and a high melt point hydrocarbon tackifying agent, such compositions unexpectedly provide improved bonding between the layers found in a disposable absorbent article. In particular, such compositions improve the bond between the nonwoven top sheet and the acquisition distribution layer.

Hot melt adhesive with high softening point tackifying agent

This invention claims hot melt adhesive compositions that can be used to form elastic composites that are useful in disposable absorbent articles. The compositions have good elastic recovery and high peel adhesion at a viscosity of less than about 20,000 cps at 177&#xb0; C. The low viscosity makes it possible to apply the adhesive at a high line speed and target application to only those areas requiring elastic performance.
