Abstract

A dermal fastener includes a first adhesive for adherence to an article and a second adhesive for adherence to skin. The second adhesive is a non-liquid water containing film including an organic polymer plasticized with a polyhydric alcohol with the organic polymer being derived from a monomeric mixture including from about 2 to about 30 pph acrylic acid to about 1 to about 30 pph of a glycolvinylether and about 0.01 to about 1.5 pph of a crosslinking agent. The first and second adhesives may also be disposed on opposite sides of a membrane if partition of fluid components in the adhesives is desired.

4. The fastener according to claim 2 wherein said cross linking agent is ETMPTA.

5. The fastener according to claim 1 wherein said glycolvinylether is selected from the group consisting of hydroxybutylvinylether, ethyleneglycolvinylether, diethylene glycol vinylether, and triethyleneglycolmethylvinylether.

6. The fastener according to claim 5 wherein said glycol- vinylether is diethylene glycol vinyl ether.

7. The fastener according to claim 5 wherein said monomeric mixture further comprises from about 35 to 60 pph of glycerol.

8. The fastener according to claim 7 wherein at least a portion of said acrylic acid is replaced with 2-acrylamido propane sulfonic acid (AMPS) or a cationic acrylic ester.

9. The fastener according to claim 1 wherein said monomeric mixture further comprises from 0.05 to 3 pph of ultraviolet sensitive curing agents.

10. The fastener according to claim 9 wherein said ultraviolet sensitive curing agent is selected from the group consisting of 2-hydroxy-2-methyl-1-phenylpropan-2-one, 4-(2-hydroxyethoxy)phenyl (2-hydroxy-2-phenyl-2-hydroxy-2-propyl)ketone, 2,2-dimethoxy-2-phenyl-acetophenone 1-[4-(2-Hydroxyethoxy)-phenyl]-2-hydroxy-2-methyl-1-propane-1-one, 1-hydroxycyclohexylphenyl ketone, trimethyl benzoyl diphenyl phosphine oxide and mixtures thereof.

11. The fastener according to claim 10 wherein said mixture comprises from 5 to 25 pph acrylic acid and from 5 to 25 pph of a glycolvinylether.

12. The fastener according to claim 11 wherein said glycolvinylether is selected from the group consisting of hydroxybutylvinylether, ethyleneglycolvinylether, diethylene glycol vinylether, and triethyleneglycolmethylvinylether.

13. The fastener according to claim 12 wherein said glycol vinylether is diethylene glycol vinyl ether.

14. The fastener according to claim 1 wherein said monomeric mixture further comprises an aldehyde reactant or neutralizer.

15. The fastener according to claim 14 wherein said aldehyde reactant or neutralizer is selected from the group consisting of hydrogen peroxide, hydroxyethylethylene urea and L-arginine hydrochloride.

16. The fastener according to claim 15 wherein said aldehyde reactant or neutralizer is 2-hydroxyethylethylene urea.

17. The fastener according to claim 1 wherein said second adhesive comprises a first layer having a relatively low peel strength for removably contacting the skin and a second layer having a selectively high peel strength for contacting said membrane.

18. The fastener according to claim 17 further comprising a scrim disposed between the second adhesive first and second layer.

19. The fastener according to claim 17 wherein said first adhesive comprises a first layer having a relatively low peel strength for removably contacting the article and a second layer having a relatively high peel strength for contacting said membrane.

20. The fastener according to claim 19 further comprising a scrim disposed between the first adhesive first and second layer.

21. The fastener according to claim 1 wherein said first adhesive has a faster drying rate, when exposed to air, than a drying rate of said second adhesive.

22. A dermal fastener comprising:

a membrane;

a first adhesive, disposed on one side of said membrane, for adherence to an article;

said first adhesive comprising a non-liquid water containing film including an organic polymer plasticized with a polyhydric alcohol (humectant) with said organic polymer being derived from a monomeric mixture comprising from about 2 to about 30 pph acrylic acid, about 1 to about 30 pph of glycovinylether, and about 0.01 to about 1.5 pph of a crosslinking agent; and
