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

The invention features a hot melt adhesive composition based on olefin polymers that can be used for elastic attachment in the manufacture of a disposable article. The hot melt adhesive includes from about 3 to about 10% by weight of a first propylene-based copolymer having a melt index measured by ASTM D1238 (190&#xb0; C., 2.16 kg) of no greater than about 5, a second propylene-based polymer with a viscosity at 190&#xb0; C. of no greater than about 5000 cps, a first tackifying agent having a softening point of at least about 90&#xb0; C. and from about 5% by weight to about 20% by weight of a plasticizer.

This invention claims low application temperature hot melt adhesive compositions including at least about 15% by weight of a first styrene block copolymer with a melt flow rate of at least about 15 g/10 minutes (190&#xb0; C., 2.16 kgs) and a diblock content of no greater than about 10% by weight.

Low application temperature hot melt adhesive composition

A hot melt wetness indicator composition that includes a water insoluble thermoplastic polymer, an anionic surfactant, a leuco dye, and a component selected from the group consisting of acid, rosin-based tackifying agent, plasticizer and combinations thereof, and is homogeneous is disclosed. The hot melt wetness indicator composition exhibits a color change after contact with water.

The present invention includes compositions relating to a hot melt adhesive that includes a copolymer of butene-1, a wax, and a tackifying resin. The present invention further relates to adhesives initially exhibiting adhesion properties and subsequently non-adhesion qualities. Methods of using these adhesives are also part of the claimed invention.

Composition and method relating to a hot melt adhesive

A hot melt pressure-sensitive adhesive composition that includes thermoplastic polymer, tackifying agent, plasticizer oil, and from at least 5% by weight to about 25% by weight vegetable wax.
