Abstract

This invention relates to a moisture-vapor-permeable pressuresensitive adhesive material for use on animal skin and nails, e.g. a surgical drape, suture strip or sheet, adhesive dressing, bandage, plaster, strapping tape, decorative nail covering, or decorative cosmetic product. The adhesive material comprises a backing material, and a pressure-sensitive adhesive on at least substantially the whole of the body adhering portion of at least one surface of said backing material, both said backing material and said adhesive being moisture-vapor-permeable and unaffected by water and at least one of said backing material and said adhesive comprising a synthetic polymer and being continuous and nonpermeable to liquid water, said adhesive material having a moisture vapor permeability of at least 300 g./sq. meter/24 hours/40* C./80 percent RH.

Claims

2. A pressure-sensitive adhesive material as claimed in claim 1, which has a moisture vapor permeability of at least 500 g./sq. meter/24 hours at 40* C. and 80 percent RH.

3. A pressure-sensitive adhesive material as claimed in claim 1, which is oxygen-permeable.

4. A pressure-sensitive adhesive material as claimed in claim 1, wherein the backing material is continuous and the adhesive is not continuous.

5. A pressure-sensitive adhesive material as claimed in claim 1, which is in the form of a surgical drape, suture strip or sheet, adhesive dressing, bandage, plaster, strapping tape, decorative nail covering, or decorative cosmetic product.

6. A moisture-vapour-permeable pressure-sensitive adhesive material for use on animal skin and nails comprising a backing material and a pressure-sensitive adhesive on at least substantially the whole of the body-adhering portion of at least one surface of said backing material, both said backing material and said adhesive being moisture-vapour-permeable and unaffected by water and at least said adhesive comprising a synthetic polymer and being continuous and nonpermeable to liquid water, said adhesive material having a moisture vapor permeability of at least 300 g./sq. meter/24 hours/ 40* C./80 percent RH.

7. A pressure-sensitive adhesive as claimed in claim 6 wherein the adhesive is a polyvinyl ethyl ethers or an acrylic ester copolymer containing hydrophilic groups.

8. A pressure-sensitive adhesive material as claimed in claim 6 wherein the backing material is noncontinuous.

9. A pressure-sensitive adhesive material as claimed in claim 8, wherein the backing material is a microporous film of plasticized polyvinyl chloride or nonwoven fabric.

10. A pressure-sensitive adhesive material as claimed in claim 9, wherein the nonwoven fabric is based on cellulose or synthetic polymer fibers which may be crimped and/or laid down in such a manner as to give an elastic fabric.

11. A pressure-sensitive adhesive material as claimed in claim 10, wherein the fabric comprises extruded composite synthetic fibers or a spun-bonded polyester fabric.

12. A moisture-vapour-permeable pressure-sensitive adhesive material for use on animal skin and nails, comprising a baking material having a pressure-sensitive adhesive on at least substantially the whole of the body-adhering portion of at least one surface of said backing material, both said backing material and said adhesive being moisture-vapour-permeable and unaffected by water and both said backing material and said adhesive comprising a synthetic polymer and being continuous and nonpermeable to liquid water, said adhesive material having a moisture vapor permeability of at least 300 g./sq.meter/24 hours/40* C./80 percent RH.

13. A pressure-sensitive adhesive material as claimed in claim 12 wherein the backing material comprises a copolymer obtainable by copolymerizing an hydroxy alkyl acrylate or methacrylate with an alkoxy alkyl acrylate or methacrylate and optionally with a minor amount of a further monomer.

14. A pressure-sensitive adhesive material as claimed in claim 12, wherein the backing material comprises a homopolymer of ethoxy ethyl methacrylate or methoxy ethyl methacrylate or a copolymer of methyl methacrylate with ethoxy ethyl methacrylate or methoxy ethyl methacrylate.

15. A pressure-sensitive adhesive material as claimed in claim 12 wherein the backing material comprises a thermoplastic polyurethane film.

16. A pressure-sensitive adhesive material as claimed in claim 12, wherein the adhesive comprises a polyvinyl ethyl ether.

17. A pressure-sensitive adhesive material as claimed in claim 12 which is in the form of a nail cover, a medical or surgical dressing, a surgical drape, a suture strip, an elastic adhesive bandage or a strapping tape.

18. A pressure-sensitive adhesive material as claimed in claim 12, which is in the form of a nail cover and the backing material has a thickness of from 1 to 3 mils.

19. A pressure-sensitive adhesive material as claimed in claim 17 which is in the form of a nail cover and in which the adhesive is applied in an amount of from 5 to 75 grams per square meter.

20. A pressure-sensitive adhesive material as claimed in claim 12 wherein the backing material comprises a copolymer obtainable by reacting an alkoxy alkyl acrylate or methacrylate with a different alkoxy alkyl acrylate or methacrylate, no monomers other than alkoxy alkyl acrylates or methacrylates or polymers formed therefrom being present in the reaction mixture.

21. A pressure-sensitive adhesive material as claimed in claim 20, wherein the backing material comprises a copolymer of ethoxyethyl methacrylate and methoxy ethyl methacrylate.

22. A pressure-sensitive adhesive material as claimed in claim 21, wherein the backing material comprises a 50/50, 60/40 or 70/30 copolymer of MEMA/EEMA.
