Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A disposable absorbent article comprising: a top sheet, an acquisition distribution layer, and a hot melt adhesive composition comprising, an olefin polymer, and from 5% by weight to 60% by weight of a high softening point hydrocarbon tackifying agent having a softening point of from 110° C. to 150° C., wherein the hot melt adhesive composition adheres the top sheet to the acquisition distribution layer, and the acquisition distribution layer is a hydrophilic substrate. 2. The disposable absorbent article of claim 1 wherein the hot melt adhesive composition further comprises from 3% by weight to 35% by weight of a plasticizer. 3. The disposable absorbent article of claim 1 wherein the hot melt adhesive composition comprises from 20% by weight to 55% by weight of the high softening point hydrocarbon tackifying agent. 4. The disposable absorbent article of claim 1 wherein the high softening point hydrocarbon tackifying agent is selected from the group consisting of aliphatic and cycloaliphatic hydrocarbon resins. 5. The disposable absorbent article of claim 1 wherein the high softening point hydrocarbon tackifying agent has an aromatic content as tested by Nuclear Magnetic Resonance (NMR) of from 0% by weight to 20% by weight. 6. The disposable absorbent article of claim 1 wherein the high softening point hydrocarbon tackifying agent is at least partially hydrogenated. 7. The disposable absorbent article of claim 1 wherein the high softening point hydrocarbon tackifying agent has a softening point of from 115° C. to 145° C. 8. The disposable absorbent article of claim 1 wherein the olefin polymer is a single site catalyzed propylene based polymer. 9. The disposable absorbent article of claim 1 wherein the olefin polymer is a single site catalyzed propylene based polymer and the hot melt adhesive composition comprises from 30% by weight to 40% by weight of the hydrocarbon tackifying agent. 10. The disposable absorbent article of claim 1 selected from the group consisting of a disposable diaper and an adult incontinence product. 11. The disposable absorbent article of claim 1 wherein the hot melt adhesive composition comprises: a. from 10% by weight to 80% by weight of a single-site catalyzed propylene based polymer and, from 15% by weight to 60% by weight of a high softening point hydrocarbon tackifying agent having a softening point of from 110° C. to 150° C.
