Claims
- 1. A laminate structure for use in a disposable absorbent article, comprising:
- a substrate;
- a topsheet having a first surface facing said substrate and a second skin-engaging surface;
- an emollient in contact with the second skin-engaging surface of said topsheet; and
- an emollient resistant hot melt adhesive disposed between and bonding said substrate to said topsheet, said adhesive consisting essentially of a blend of:
- (a) about 10% to about 65% by weight of a polybutylene copolymer, homopolymer, or blend thereof;
- about 15% to about 70% by weight of a tackifying resin, said tackifying resin is selected from the group consisting of fully hydrogenated aromatic hydrocarbon resins, fully hydrogenated aliphatic hydrocarbon resins, and mixtures thereof;
- about 0% to about 30% by weight of a plasticizer;
- about 0% to about 20% by weight of a wax; and
- about 0.1% to about 2% by weight of a stabilizer, wherein the minimum polymer content is 20% by weight.
- 2. The laminate structure of claim 1 wherein the plasticizer is selected from the group consisting of mineral oil and polybutene.
- 3. The laminate structure of claim 1 wherein the adhesive comprises:
- (a) about 37% by weight of a polybutylene copolymer and homopolymer blend;
- (b) about 51% by weight of a tackifying resin;
- (c) about 11% by weight of a wax; and
- (d) about 1% by weight of a stabilizer.
- 4. The laminate structure of claim 1 wherein said substrate is composed of a material selected from the group consisting of absorbent cellulosic material, polyolefins, superabsorbent polymers, polyesters, elastics and combinations thereof.
- 5. The laminate structure of claim 1 wherein said topsheet is selected from the group consisting of nonwoven fabric, tissue, absorbent fluff, superabsorbents, elastics, a polyolefin, and combinations thereof.
- 6. The laminate structure of claim 5 wherein said polyolefin comprises a polyethylene or polypropylene layer.
- 7. The laminate structure of claim 1 wherein the disposable absorbent article is a diaper.
- 8. The laminate structure of claim 1 wherein the disposable absorbent article is a feminine care pad.
- 9. The laminate structure of claim 1 wherein said resin is a fully hydrogenated C9 type.
- 10. The laminate structure of claim 1 wherein said emollient is coated on said topsheet.
