Claims18
An adhesive sheet for application on skin which comprises an adhesive layer and a laminated film comprising an elastomer film having provided on one side thereof a supporting film, said adhesive layer being formed on the elastomer film side of the laminated film, wherein the adhesive layer mainly comprises an acrylic polymer and both the adhesive layer and the supporting film comprise a component compatible with the acrylic polymer that is liquid or pasty at ordinary temperature.
A process for the production of an adhesive sheet for application on skin, which adhesive sheet comprises an adhesive layer and a laminated film comprising an elastomer film having provided on one side thereof a supporting film, said adhesive layer being formed on the elastomer film side of the laminated film, wherein the adhesive layer comprises a polymer and both the adhesive layer and the supporting film comprise a component compatible with the polymer and liquid or pasty at ordinary temperature, which process for the production of the adhesive sheet comprises applying an adhesive comprising the component liquid or pasty at ordinary temperature to the laminated film, and then allowing a part of the liquid or pasty component comprised in the adhesive to move toward the supporting film so that it is present therein.
A process for the production of an adhesive sheet for application on skin, which adhesive sheet comprises an adhesive layer and a laminated film comprising an elastomer film having provided on one side thereof a supporting film, said adhesive layer being formed on the elastomer film side of the laminated film, wherein the adhesive layer comprises a polymer and both the adhesive layer and the supporting film comprise a component compatible with the polymer that is liquid or pasty at ordinary temperature, which process for the production of the adhesive sheet comprises forming the adhesive layer on the laminated film made of the supporting film and the elastomer film either or both of which have a component liquid or pasty at ordinary temperature incorporated therein on the elastomer film side thereof, and then allowing a part of the liquid or pasty component comprised in either or both of the supporting film and the elastomer film to move toward the adhesive layer.
