Abstract
The pressure sensitive transferring adhesive tape which transfers adhesive agent layer alone to an adherent is widely well-known, and in this case, the adhesive agent layer applied to a supporter has to be cut after it has been transferred to the adherent. However, since the adhesive layer is coated continuously, this type has a weak point that the adhesive agent layer causes problem of stringiness and stretching and cannot be cut smoothly. In the present invention, above mentioned weak points are dissolved by coating adhesive agent layer by discontinuous island shape pattern or by making the surface of adhesive agent layer to have concave and convex shape.
