ABSTRACT:
A process for preparing permeable adhesive tapes, which comprises dispersing water or water and a water absorptive high-molecular weight compound homogeneously in a solution of a natural or synthethic rubber or acrylic pressure sensitive adhesive agent in an organic solvent, applying the dispersion onto a releasing agent applied sheet, drying the adhesive agent applied sheet, and laminating a porous backing material on the adhesive agent applied surface to obtain a permeable adhesive tape.
