Abstract

The present invention provides an adhesive material to be adhered to the skin etc., which maintains, for a certain time period after adhesion thereof to the skin surface, suitable adhesiveness that does not allow easy peeling or cause irritation to the skin, and which permits, when it is to be peeled off from the skin surface after the lapse of a desired certain time period, easy peeling without causing pain or physical irritation, and an adhesive preparation containing the adhesive material and a percutaneously absorbable drug in the adhesive layer. Specifically, the present invention provides an adhesive material containing a support and an adhesive layer laminated on one surface of the support, wherein the adhesive layer has an apparent viscosity at 30°C of 0.2×10 4 to 10×10 4Pa.cndot.s and comprises two kinds of synthetic rubbers having different flowability.

Claims (15)

1. An adhesive material comprising a support and an adhesive layer laminated on one surface of the support, wherein the adhesive layer has an apparent viscosity at 30°C of 0.2×10 4 to 10×10 4Pa.cndot.s and comprises two kinds of synthetic rubbers having different flowability.
2. The adhesive material of claim 1, wherein said adhesive layer may further comprise a tackifier.
3. The adhesive material of claim 2, wherein said adhesive layer further comprises an organic liquid compatible with said two kinds of synthetic rubbers and the tackifier.
4. The adhesive material of claim 3, wherein the organic liquid is contained in a proportion of not more than 20% of the total weight of said adhesive layer.
5. The adhesive material of claim 1 or 2, wherein the two kinds of synthetic rubbers comprise a first synthetic rubber, which is a branched aliphatic hydrocarbon having a Staudinger Index of 170-300 cm3/g, and a second synthetic rubber, which is a branched aliphatic hydrocarbon having a Staudinger Index of 30-60 cm3/g.
6. The adhesive material of claim 5, wherein the branched aliphatic hydrocarbon is a 2-methylpropene polymer.
7. The adhesive material of claim 2, wherein the tackifier is an ethylethylene polymer, a 1,2-dimethylethylene polymer or an ethylethylene-1,2-dimethylethylene copolymer having a kinematic viscosity at 40°C of 200-4000 mm2/s.
8. The adhesive material of claim 2, wherein the tackifier is an alicyclic saturated hydrocarbon resin having a softening point of 70-125°C.
9. The adhesive material of claim 2, wherein the two kinds of synthetic rubbers comprise a first synthetic rubber and a second synthetic rubber having a lower Staudinger Index than the first synthetic rubber, and a mixing ratio of the first synthetic rubber:the second synthetic rubber:tackifier is
10:12-20:7-11 by weight.
10. The adhesive-material of claim 2, wherein the two kinds of synthetic rubbers comprise a first synthetic rubber and a second synthetic rubber having a lower Staudinger Index than the first synthetic rubber, and a mixing ratio of the first synthetic rubber:the second synthetic rubber:tackifier is 10:12-20:2-6 by weight.
11. The adhesive material of claim 2, wherein the two kinds of synthetic rubbers comprise a first synthetic rubber and a second synthetic rubber having a lower Saudinger Index than the first synthetic rubber, and a mixing ratio of the first synthetic rubber:the second synthetic rubber:tackifier is 10:25-45:0-2 by weight.
12. The adhesive material of claim 3 or 4, wherein the organic liquid is at least one member selected from isopropyl myristate and a branched long-chain alcohol.
13. The adhesive material of claim 12, wherein the branched long-chain alcohol is at least one member selected from isostearyl alcohol and octyldodecanol.
14. The adhesive material of claim 12 or 13, wherein the organic liquid is isopropyl myristate, the organic liquid optionally further comprises a branched long-chain alcohol, and a mixing ratio of isopropyl myristate:branched long-chain alcohol is 1:0-4 by weight.
15. An adhesive preparation comprising a percutaneously absorbable drug in the adhesive layer of the adhesive material of claim 1 to claim 14.
