An electrically peelable pressure sensitive adhesive composition, which contains an acrylic polymer (A), a (poly)alkylene polyol (B) having a number average molecular weight of no greater than 2000, and an ammonium salt (C), has a high adhesiveness before voltage application, but the adhesiveness can decrease effectively by voltage application for a short time.

Electrically peelable adhesive composition and electrically peelable adhesive sheet, and method for using electrically peelable adhesive sheet

A pressure-sensitive adhesive composition including an addition reaction type silicone polymer as a component (A); an ultraviolet absorber as a component (B); and a platinum group metal catalyst as a component (C). The ultraviolet absorber as the component (B) includes a benzophenone-based ultraviolet absorber and its amount is set to a value within the range of 1 part to 4 parts by weight relative to 100 parts by weight of the addition reaction type silicone polymer as the component (A). The amount of the platinum group metal catalyst as the component (C) is set to a value within the range of 0.001 parts to 0.05 parts by weight relative to 100 parts by weight of the addition reaction type silicone polymer as the component (A).

Disclosed herein is a package material for adhesive bandage which is used for packaging therein an adhesive bandage including a surface base having one surface, an adhesive layer provided on the one surface of the surface base and a releasing sheet attached to the adhesive layer so as to cover it. The package material comprises a first sheet having a first sheet base and a first cold seal layer provided on the first sheet base, and a second sheet having a second sheet base and a second cold seal layer provided on the second sheet base. The first cold seal layer faces the surface base of the adhesive bandage and the second cold seal layer faces the releasing sheet of the adhesive bandage when the adhesive bandage is packaged in the package material. Further, each of the first cold seal layer and the second cold seal layer is formed of a mixture of rubber and acrylic resin, and an amount of the rubber contained in the first cold seal layer is smaller than an amount of the rubber contained in the second cold seal layer.

Package material for adhesive bandage and packaged adhesive bandage

The present invention provides a percutaneous absorption system and a percutaneous absorption method, which have a simple constitution and can realize the easy and continuous percutaneous absorption of medicine even when the medicine is formed of a water-soluble oligomer solution or a high-molecular solution. In the percutaneous absorption system comprising a medicine reservoir portion having a medicine holding portion which holds medicine therein and a support portion for supporting the medicine reservoir portion, the support portion including an adhesive layer and a substrate having medicine non-permeating property, the system is provided with an elastic member for applying pressure to the medicine held in the inside of the medicine reservoir portion, and by breaking the substrate having medicine non-permeating property in the support portion using a mechanical stimulus such as an injection needle or the like, the medicine is released (delivered) at a fixed rate.
